Heart Failure

It remains early days for transcatheter mitral-valve replacement (TMVR) as a minimally invasive way to treat severe, mitral regurgitation (MR), but it’s even earlier days for TMVR as an endovascular procedure. Most of the technique’s limited experience with a dedicated mitral prosthesis has involved transapical delivery.

But now a 15-patient study of transfemoral, transeptal TMVR – with a prosthesis designed for the mitral position and previously tested only transapically – has shown good 30-day results in that MR was essentially abolished with virtually no paravalvular leakage.

Nor were there adverse clinical events such as death, stroke, reintervention, or new need for a pacemaker in any of the high-surgical-risk patients with MR in this feasibility study of the transfemoral Intrepid TMVR System (Medtronic). Implantation failed, however, in one patient who then received a surgical valve via sternotomy.

The current cohort is part of a larger ongoing trial that will track whether patients implanted transfemorally with the Intrepid also show reverse remodeling and good clinical outcomes over at least a year. That study, called APOLLO, is one of several exploring dedicated TMVR valves from different companies, with names like SUMMIT, MISCEND, and TIARA-2.

Currently, TMVR is approved in the United States only using one device designed for the aortic position and only for treating failed surgical mitral bioprostheses in high-risk patients.

If the Intrepid transfemoral system has an Achilles’ heel, at least in the current iteration, it might be its 35 F catheter delivery system that requires surgical access to the femoral vein. Seven of the patients in the small series experienced major bleeding events, including six at the femoral access site, listed as major vascular complications.

Overall, the study’s patients “were extremely sick with a lot of comorbidity. A lot of them had atrial fibrillation, a lot of them were on anticoagulation to start with,” observed Firas Zahr, MD, Oregon Health & Science University, Portland, as part of his presentation of the study at Transcatheter Cardiovascular Therapeutics (TCT) 2021, held virtually as well as onsite in Orlando, Florida.

All had moderate-to-severe, usually primary MR; two thirds of the cohort had been in NYHA class III or IV at baseline, and 40% had been hospitalized for heart failure within the past year. Eight had a history of cardiovascular surgery, and eight had diabetes. Their mean Society of Thoracic Surgeons Predicted Risk of Mortality (STS-PROM) score was 4.7, Dr. Zahr reported.

“At 30 days, there was a significant improvement in their heart failure classification; the vast majority of the patients were [NYHA] class I and class II,” said Dr. Zahr, who is also lead author on the study’s Nov. 6 publication in JACC: Cardiovascular Interventions.

Observers of the study at TCT 2021 seemed enthusiastic about the study’s results but recognized that TMVR in its current form still has formidable limitations.

“This is clearly an exciting look into the future and very reassuring to a degree, aside from the complications, which are somewhat expected as we go with 30-plus French devices,” Rajiv Tayal, MD, MPH, said at a press conference on the Intrepid study held before Dr. Zahr’s formal presentation. Dr. Tayal is an interventional cardiologist with Valley Health System, Ridgewood, New Jersey, and New York Medical College, Valhalla.

“I think we’ve all learned that transapical [access] is just not a viable procedure for a lot of these patients, and so we’ve got to get to transfemoral,” Susheel K. Kodali, MD, interventional cardiologist at New York-Presbyterian/Columbia University Irving Medical Center, said at the same forum.

A 35 F device “is going to be too big,” he said. However, “it is the first step to iterate to a smaller device.” Dr. Kodali said his center contributed a patient to the study, and he is listed as a coauthor on the publication.

The delivery system’s large profile is only part of the vascular complication issue. Not only did the procedure require surgical cutdown for venous access, but “we were fairly aggressive in anticoagulating these patients with the fear of thrombus formation,” Dr. Zahr said in the discussion following his presentation.

“A postprocedure anticoagulation regimen is recommended within the protocol, but ultimate therapy was left to the discretion of the treating site physician,” the published report states, noting that all 14 patients with successful TMVR were discharged on warfarin. They included 12 who were also put on a single antiplatelet and one given dual antiplatelet therapy on top of the oral anticoagulant.

“One thing that we learned is that we probably should standardize our approach to perioperative anticoagulation,” Dr. Zahr observed. Also, a 29 F sheath for the system is in the works, “and we’re hoping that with smaller sheath size, and hopefully going even to percutaneous, might have an impact on lowering the vascular complications.”

Explanations for the “higher-than-expected vascular complication rate” remains somewhat unclear, agreed an editorial accompanying the study’s publication, “but may include a learning curve with the system, the large introducer sheath, the need for surgical cutdown, and postprocedural anticoagulation.”

For trans-septal TMVR to become a default approach, “venous access will need to be achieved percutaneously and vascular complications need to be infrequent,” contends the editorial, with lead author Mohamad Alkhouli, MD, Mayo Clinic, Rochester, Minn.

“These data provide a glimpse into the future of TMVR. The excellent short-term safety and effectiveness of this still very early-stage procedure represent a major step forward in the field,” they write.

Virtual platforms democratized scientific meetings during the COVID-19 pandemic but, as any meeting-goer will tell you, it’s the questions from the floor and the back-and-forth of an expert panel that often reveal the importance of and/or problems with a presentation. It’s the scrutiny that makes the science resonate, especially in this postfactual era.

The all-virtual American Heart Association Scientific Sessions 2021 is looking to recreate the engagement of an in-person meeting by offering more live interactive events. They range from seven late-breaking science (LBS) sessions to Saturday’s fireside chat on the Pfizer and Moderna COVID-19 vaccines and Monday’s dive into the controversial new AHA/American College of Cardiology Chest Pain guidelines.

To help digest the latest science, attendees will be able to have their questions answered in real-time via Slido, meet with the trialists, and hear live commentary from key opinion leaders after the live events. A networking function will also allow attendees and exhibitors to chat or meet virtually.

“In this day and age, many people pretty quickly can get access to the science but it’s what I call the IC sort of phenomenon – the presentation of the information, the context of the information, putting it into how I’m going to use it in my practice, and then the critical appraisal – that’s what most people want at the Scientific Sessions,” program committee chair Manesh R. Patel, MD, of Duke University School of Medicine, said in an interview. “We’re all craving ways in which we can interact with one another to put things in context.”

Plans for a hybrid in-person meeting in Boston were scuttled in September because of the Delta variant surge, but the theme of the meeting remained: “One World. Together for Science.” Attendees will be able to access more than 500 live and on-demand sessions including 117 oral abstracts, 286 poster sessions, 59 moderated digital posters, and over a dozen sessions focused on strategies to promote health equity.

“Last year there was a Presidential Session and a statement on structural racism, so we wanted to take the next step and say, What are the ways in which people are starting to interact and do things to make a difference?” explained Dr. Patel. “So, this year, you’ll see different versions of that from the Main Event session, which has some case vignettes and a panel discussion, to other health equity sessions that describe not just COVID care, but blood pressure care, maternal-fetal medicine, and congenital kids. Wherever we can, we’ve tried to infuse it throughout the sessions and will continue to.”

Late-breaking science

The LBS sessions kick off at 9:30 a.m. ET Saturday with AVATAR, a randomized trial of aortic valve replacement vs. watchful waiting in severe aortic stenosis proved asymptomatic through exercise testing.

“The findings of that trial, depending on what they are, could certainly impact clinical practice because it’s a very common scenario in which we have elderly patients with aortic valve stenosis that might be severe but they may not be symptomatic,” he said.

It’s followed by a randomized trial from the Cardiothoracic Surgical Trials Network, examining whether tricuspid repair at the time of mitral valve surgery leads to beneficial outcomes. “I think it’s a pretty important study,” Dr. Patel said, “because it’ll again affect how we think about our clinical practice.”

Rounding out the LBS.01 session is RAPID CABG, comparing early vs. delayed coronary bypass graft surgery (CABG) in patients with acute coronary syndromes on ticagrelor, and the pivotal U.S. VEST trial of an external support device already approved in Europe for saphenous vein grafts during CABG.

Saturday’s LBS.02 at 3:00 p.m. ET is devoted to hypertension and looks at how the COVID-19 pandemic affected blood pressure control. There’s also a study of remotely delivered hypertension and lipid management in 10,000 patients across the Partners Healthcare System and a cluster randomized trial of a village doctor–led blood pressure intervention in rural China.

Sunday’s LBS.03 at 8:00 a.m. ET is focused on atrial arrhythmias, starting with the CRAVE trial examining the effect of caffeine consumption on cardiac ectopy burden in 108 patients using an N-of-1 design and 2-day blocks on and off caffeine. “There’s an ability to identify a dose response that you get arrhythmias when you increase the amount of coffee you drink vs. not in an individual, so I think that will be likely discussed a lot and worth paying attention to,” Dr. Patel said.

The session also includes GIRAF, a comparison of cognitive outcomes with dabigatran (Pradaxa) vs. warfarin (Coumadin) in nonvalvular atrial fibrillation (AF); PALACS, a randomized trial examining whether left-sided pericardiotomy prevents AF after cardiac surgery; and AMAZE, which study sponsor AtriCure revealed missed its primary efficacy endpoint of freedom from AF with the LARIAT suture delivery device for left atrial appendage closure plus pulmonary vein isolation.

LBS.04 at 3:30 p.m. ET Sunday takes on digital health, with results from the nonrandomized Fitbit Heart Study on AF notifications from 450,000 participants wearing a single-lead ECG patch. “A lot of technologies claim that they can detect things, and we should ask that people go through the rigorous evaluation to see if they in fact do. So, in that respect, I think it›s an important step,” observed Dr. Patel.

Also on tap is I-STOP-AFib, another N-of-1 study using mobile apps and the AliveCor device to identify individual AF triggers; and REVeAL-HF, a 4,000-patient study examining whether electronic alerts that provide clinicians with prognostic information on their heart failure (HF) patients will reduce mortality and 30-day HF hospitalizations.

LBS.05 at 5:00 p.m. ET provides new information from EMPEROR-Preserved in HF with preserved ejection fraction and main results from EMPULSE, also using the sodium-glucose cotransporter 2 (SGLT2) inhibitor empagliflozin (Jardiance) in 530 patients hospitalized for acute HF.

The session also features CHIEF-HF, a randomized trial leveraging mobile technologies to test whether 12 weeks of another SGLT2 inhibitor, canagliflozin (Invokana), is superior to placebo for improving HF symptoms; and DREAM-HF, a comparison of transendocardial delivery of allogeneic mesenchymal precursor cells vs. a sham comparator in chronic HF as a result of left ventricular systolic dysfunction.

Monday’s LBS.06 at 8:00 a.m. ET details the safety and cholesterol-lowering efficacy of MK-0616, an investigational oral PCSK9 inhibitor. “It’s just a phase 2 [trial], but there’s interest in an oral PCSK9 inhibitor, given that the current ones are subcutaneous,” Dr. Patel said.

Results will also be presented from PREPARE-IT 2, which tested icosapent ethyl vs. placebo in outpatients with COVID-19. In the recently reported PREPARE-IT 1, a loading dose of icosapent ethyl failed to reduce the risk of hospitalization with SARS-CoV-2 infection among at-risk individuals.

LBS.07 at 11:00 a.m. Monday completes the late-breakers with new results from ASCEND, this time examining the effect of aspirin on dementia and cognitive impairment in patients with diabetes.

Next up is a look at the effectiveness of P2Y12 inhibitors in hospitalized patients with COVID-19 in the adaptive ACTIV-4a trial, followed by results of the pivotal phase 3 REVERSE-IT trial of bentracimab, a recombinant human monoclonal antibody antigen fragment designed to reverse the antiplatelet activity of ticagrelor in the event of major bleeding or when urgent surgery is needed.

Closing out the session is AXIOMATIC-TKR, a double-blind comparison of the safety and efficacy of the investigational oral factor XI anticoagulant JNJ-70033093 vs. subcutaneous enoxaparin (Lovenox) in elective total knee replacement.

For those searching for more AHA-related science online, the Resuscitation Science Symposium (ReSS) will run from this Friday through Sunday and the Quality of Care and Outcomes Research (QCOR) Scientific Sessions will take the stage next Monday, Nov. 15.

Patel, MD, of Duke University School of Medicine, said in an interview. “We’re all craving ways in which we can interact with one another to put things in context.”

Plans for a hybrid in-person meeting in Boston were scuttled in September because of the Delta variant surge, but the theme of the meeting remained: “One World. Together for Science.” Attendees will be able to access more than 500 live and on-demand sessions including 117 oral abstracts, 286 poster sessions, 59 moderated digital posters, and over a dozen sessions focused on strategies to promote health equity.

“Last year there was a Presidential Session and a statement on structural racism, so we wanted to take the next step and say, What are the ways in which people are starting to interact and do things to make a difference?” explained Dr. Patel. “So, this year, you’ll see different versions of that from the Main Event session, which has some case vignettes and a panel discussion, to other health equity sessions that describe not just COVID care, but blood pressure care, maternal-fetal medicine, and congenital kids. Wherever we can, we’ve tried to infuse it throughout the sessions and will continue to.”

Late-breaking science

The LBS sessions kick off at 9:30 a.m. ET Saturday with AVATAR, a randomized trial of aortic valve replacement vs. watchful waiting in severe aortic stenosis proved asymptomatic through exercise testing.

“The findings of that trial, depending on what they are, could certainly impact clinical practice because it’s a very common scenario in which we have elderly patients with aortic valve stenosis that might be severe but they may not be symptomatic,” he said.

It’s followed by a randomized trial from the Cardiothoracic Surgical Trials Network, examining whether tricuspid repair at the time of mitral valve surgery leads to beneficial outcomes. “I think it’s a pretty important study,” Dr. Patel said, “because it’ll again affect how we think about our clinical practice.”

Rounding out the LBS.01 session is RAPID CABG, comparing early vs. delayed coronary bypass graft surgery (CABG) in patients with acute coronary syndromes on ticagrelor, and the pivotal U.S. VEST trial of an external support device already approved in Europe for saphenous vein grafts during CABG.

Saturday’s LBS.02 at 3:00 p.m. ET is devoted to hypertension and looks at how the COVID-19 pandemic affected blood pressure control. There’s also a study of remotely delivered hypertension and lipid management in 10,000 patients across the Partners Healthcare System and a cluster randomized trial of a village doctor–led blood pressure intervention in rural China.

Sunday’s LBS.03 at 8:00 a.m. ET is focused on atrial arrhythmias, starting with the CRAVE trial examining the effect of caffeine consumption on cardiac ectopy burden in 108 patients using an N-of-1 design and 2-day blocks on and off caffeine. “There’s an ability to identify a dose response that you get arrhythmias when you increase the amount of coffee you drink vs. not in an individual, so I think that will be likely discussed a lot and worth paying attention to,” Dr. Patel said.

The session also includes GIRAF, a comparison of cognitive outcomes with dabigatran (Pradaxa) vs. warfarin (Coumadin) in nonvalvular atrial fibrillation (AF); PALACS, a randomized trial examining whether left-sided pericardiotomy prevents AF after cardiac surgery; and AMAZE, which study sponsor AtriCure revealed missed its primary efficacy endpoint of freedom from AF with the LARIAT suture delivery device for left atrial appendage closure plus pulmonary vein isolation.

LBS.04 at 3:30 p.m. ET Sunday takes on digital health, with results from the nonrandomized Fitbit Heart Study on AF notifications from 450,000 participants wearing a single-lead ECG patch. “A lot of technologies claim that they can detect things, and we should ask that people go through the rigorous evaluation to see if they in fact do. So, in that respect, I think it›s an important step,” observed Dr. Patel.

Also on tap is I-STOP-AFib, another N-of-1 study using mobile apps and the AliveCor device to identify individual AF triggers; and REVeAL-HF, a 4,000-patient study examining whether electronic alerts that provide clinicians with prognostic information on their heart failure (HF) patients will reduce mortality and 30-day HF hospitalizations.

LBS.05 at 5:00 p.m. ET provides new information from EMPEROR-Preserved in HF with preserved ejection fraction and main results from EMPULSE, also using the sodium-glucose cotransporter 2 (SGLT2) inhibitor empagliflozin (Jardiance) in 530 patients hospitalized for acute HF.

The session also features CHIEF-HF, a randomized trial leveraging mobile technologies to test whether 12 weeks of another SGLT2 inhibitor, canagliflozin (Invokana), is superior to placebo for improving HF symptoms; and DREAM-HF, a comparison of transendocardial delivery of allogeneic mesenchymal precursor cells vs. a sham comparator in chronic HF as a result of left ventricular systolic dysfunction.

Monday’s LBS.06 at 8:00 a.m. ET details the safety and cholesterol-lowering efficacy of MK-0616, an investigational oral PCSK9 inhibitor. “It’s just a phase 2 [trial], but there’s interest in an oral PCSK9 inhibitor, given that the current ones are subcutaneous,” Dr. Patel said.

Results will also be presented from PREPARE-IT 2, which tested icosapent ethyl vs. placebo in outpatients with COVID-19. In the recently reported PREPARE-IT 1, a loading dose of icosapent ethyl failed to reduce the risk of hospitalization with SARS-CoV-2 infection among at-risk individuals.

LBS.07 at 11:00 a.m. Monday completes the late-breakers with new results from ASCEND, this time examining the effect of aspirin on dementia and cognitive impairment in patients with diabetes.

Next up is a look at the effectiveness of P2Y12 inhibitors in hospitalized patients with COVID-19 in the adaptive ACTIV-4a trial, followed by results of the pivotal phase 3 REVERSE-IT trial of bentracimab, a recombinant human monoclonal antibody antigen fragment designed to reverse the antiplatelet activity of ticagrelor in the event of major bleeding or when urgent surgery is needed.

Closing out the session is AXIOMATIC-TKR, a double-blind comparison of the safety and efficacy of the investigational oral factor XI anticoagulant JNJ-70033093 vs. subcutaneous enoxaparin (Lovenox) in elective total knee replacement.

For those searching for more AHA-related science online, the Resuscitation Science Symposium (ReSS) will run from this Friday through Sunday and the Quality of Care and Outcomes Research (QCOR) Scientific Sessions will take the stage next Monday, Nov. 15.

In a new scientific statement on diet and lifestyle recommendations, the American Heart Association is highlighting, for the first time, structural challenges that impede the adoption of heart-healthy dietary patterns.

American Heart Association

This is in addition to stressing aspects of diet that improve cardiovascular health and reduce cardiovascular risk, with an emphasis on dietary patterns and food-based guidance beyond naming individual foods or nutrients.

The 2021 Dietary Guidance to Improve Cardiovascular Health scientific statement, developed under Alice H. Lichtenstein, DSc, chair of the AHA writing group, provides 10 evidence-based guidance recommendations to promote cardiometabolic health.

“The way to make heart-healthy choices every day,” said Dr. Lichtenstein, of the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University in Boston, in a statement, “is to step back, look at the environment in which you eat, whether it be at home, at work, during social interaction, and then identify what the best choices are. And if there are no good choices, then think about how you can modify your environment so that there are good choices.”

The statement, published in Circulation, underscores growing evidence that nutrition-related chronic diseases have maternal-nutritional origins, and that prevention of pediatric obesity is a key to preserving and prolonging ideal cardiovascular health.

The features are as follows:

• Adjust energy intake and expenditure to achieve and maintain a healthy body weight. To counter the shift toward higher energy intake and more sedentary lifestyles over the past 3 decades, the statement recommends at least 150 minutes of moderate physical activity per week, adjusted for individual’s age, activity level, sex, and size.
• Eat plenty of fruits and vegetables; choose a wide variety. Observational and intervention studies document that dietary patterns rich in varied fruits and vegetables, with the exception of white potatoes, are linked to a lower risk of cardiovascular disease (CVD). Also, whole fruits and vegetables, which more readily provide fiber and satiety, are preferred over juices.
• Choose whole grain foods and products made mostly with whole grains rather than refined grains. Evidence from observational, interventional, and clinical studies confirm the benefits of frequent consumption of whole grains over infrequent consumption or over refined grains in terms of CVD risk, coronary heart disease (CHD), stroke, metabolic syndrome, cardiometabolic risk factors, laxation, and gut microbiota.
• Choose healthy sources of protein, mostly from plants (legumes and nuts).
• Higher intake of legumes, which are rich in protein and fiber, is associated with lower CVD risk, while higher nut intake is associated with lower risks of CVD, CHD, and stroke mortality/incidence. Replacing animal-source foods with plant-source whole foods, beyond health benefits, lowers the diet’s carbon footprint. Meat alternatives are often ultraprocessed and evidence on their short- and long-term health effects is limited. Unsaturated fats are preferred, as are lean, nonprocessed meats.
• Use liquid plant oils rather than tropical oils (coconut, palm, and palm kernel), animal fats (butter and lard), and partially hydrogenated fats. Saturated and trans fats (animal and dairy fats, and partially hydrogenated fat) should be replaced with nontropical liquid plant oils. Evidence supports cardiovascular benefits of dietary unsaturated fats, especially polyunsaturated fats primarily from plant oils (e.g. soybean, corn, safflower and sunflower oils, walnuts, and flax seeds).
• Choose minimally processed foods instead of ultraprocessed foods. Because of their proven association with adverse health outcomes, including overweight and obesity, cardiometabolic disorders (type 2 diabetes, CVD), and all-cause mortality, the consumption of many ultraprocessed foods is of concern. Ultraprocessed foods include artificial colors and flavors and preservatives that promote shelf stability, preserve texture, and increase palatability. A general principle is to emphasize unprocessed or minimally processed foods.
• Minimize intake of beverages and foods with added sugars. Added sugars (commonly glucose, dextrose, sucrose, corn syrup, honey, maple syrup, and concentrated fruit juice) are tied to elevated risk for type 2 diabetes, high cholesterol, and excess body weight. Findings from meta-analyses on body weight and metabolic outcomes for replacing added sugars with low-energy sweeteners are mixed, and the possibility of reverse causality has been raised.
• Choose and prepare foods with little or no salt. In general, the effects of sodium reduction on blood pressure tend to be higher in Black people, middle-aged and older people, and those with hypertension. In the United States, the main combined sources of sodium intake are processed foods, those prepared outside the home, packaged foods, and restaurant foods. Potassium-enriched salts are a promising alternative.
• If you don’t drink alcohol, don’t start; if you choose to drink, limit intake.
• While relationships between alcohol intake and cardiovascular outcomes are complex, the 2020 Dietary Guidelines Advisory Committee recently concluded that those who do drink should consume no more than one drink per day and should not drink alcohol in binges; the 2020 Dietary Guidelines for Americans con­tinues to recommend no more than one drink per day for women and two drinks per day for men.
• Adhere to the guidance regardless in all settings. Food-based dietary guidance applies to all foods and beverages, regardless of where prepared, procured, and consumed. Policies should be enacted that encourage healthier default options (for example, whole grains, minimized sodium and sugar content).

Recognizing impediments

The AHA/ASA scientific statement closes with the declaration: “Creating an environment that facilitates, rather than impedes, adherence to heart-healthy dietary patterns among all individuals is a public health imperative.” It points to the National Institutes of Health’s 2020-2030 Strategic Plan for National Institutes of Health Nutrition Research, which focuses on precision nutrition as a means “to determine the impact on health of not only what individuals eat, but also of why, when, and how they eat throughout the life course.”

Ultimately, precision nutrition may provide personalized diets for CVD prevention. But the “food environment,” often conditioned by “rampant nutrition misinformation” through local, state, and federal practices and policies, may impede the adoption of heart-healthy dietary patterns. Factors such as targeted food marketing (for example, of processed food and beverages in minority neighborhoods), structural racism, neighborhood segregation, unhealthy built environments, and food insecurity create environments in which unhealthy foods are the default option.”

These factors compound adverse dietary and health effects, and underscore a need to “directly combat nutrition misinformation among the public and health care professionals.” They also explain why, despite widespread knowledge of heart-healthy dietary pattern components, little progress has been made in achieving dietary goals in the United States.

Datascope/Getinge/Maquet is recalling CardioSave Hybrid and Rescue intra-aortic balloon pumps (IABPs) because some battery packs may have a shortened run time and fail unexpectedly, according to a medical device recall notice posted on the U.S. Food and Drug Administration website.

The FDA has identified this as a class I recall, the most serious type of recall, because of the risk for serious injury or death.

The recalled IABPs have substandard batteries that do not meet performance specifications and were mistakenly released to a limited number of customers.

If a patient requires life-supporting therapy with an IABP and the device does not work or stops working during use because of battery failure, the patient will be at risk for serious injury, including death, the FDA cautions.

Both IABP monitors display battery life and have low battery alarms when alternative power sources are needed.

Datascope/Getting/Maquet has received six complaints but no reports of injury or death related to this issue.

“However, there is a potential for underreporting since the end user reporting a failed battery or short battery run time cannot be aware that they originally received a substandard battery,” the FDA said.

The recall involves 137 battery packs distributed in the United States between Sept. 23, 2017, and Aug. 17, 2021. Product codes and lot numbers are available in the recall notice.  

The company sent an urgent medical device removal letter to customers requesting that they check inventory to determine if there are any CardioSave LiIon battery packs with part number/reference number 0146-00-0097 and with serial numbers listed in the letter.

Customers are asked to replace any affected battery with an unaffected battery and remove the affected product from areas of use.

The company will issue credit or a replacement battery at no cost to the facility upon receipt of the response form attached to the letter.

Distributors who shipped any affected product to customers are asked to forward the device removal letter to customers.

All customers, regardless of whether or not they have defective batteries, are asked to complete and sign the response form to acknowledge that they received the notification and disposed of the affected batteries.

Completed forms can be scanned and emailed to Datascope/Getinge/Maquet at [email protected] or by FAX to 1-877-446-3360.

Customers who have questions about this recall should contact their Datascope/Getinge/Maquet sales representative or, for technical questions, customer service (1-888-943-8872, option 2), Monday through Friday, 8:00 a.m. to 6:00 p.m. ET.

Any adverse events or suspected adverse events related to the recalled CardioSave Hybrid/Rescue IABPs should be reported to the FDA through MedWatch, its adverse event reporting program.

“Short-term hospitalization [for reasons other than diabetes] may not be the time to intervene in long-term diabetes management,” researchers conclude.

They found that, in a national cohort of older almost entirely male veterans with non–insulin-treated type 2 diabetes who were hospitalized for non–diabetes-related common medical conditions, intensified diabetes treatment on hospital discharge was linked to an increased risk of severe hypoglycemia in the immediate postdischarge period.

However, diabetes treatment intensification – that is, receiving a prescription for a new or higher dose of diabetes medicine – was not associated with decreased risks of severe hyperglycemia or with improved glycemic (hemoglobin A1c) control at 30 days or 1 year, according to study results, published in JAMA Network Open.

“We didn’t see a reduction in diabetes emergencies in more intensively treated patients,” lead investigator Timothy S. Anderson, MD, said in an interview.

Also, importantly, there was a low rate of persistence with the new treatment. “Half of the patients were no longer taking these [intensified diabetes medicines] at 1 year, which tells me that context is key,” he pointed out. “If a patient is in the hospital for diabetes [unlike the patients in this study], I think it makes a lot of sense to modify and adjust their regimen to try to help them right then and there.”

The overall risk of severe hyperglycemia or severe hypoglycemia was pretty small in the overall cohort, Dr. Anderson noted, “but we do put people at risk of leaving the hospital and ending up back in the hospital with low blood sugar when we intensify medications, and there’s not necessarily a good signal to suggest that it’s all that urgent to change these medicines.”

Instead, the “safer path” may be to make recommendations to the patient’s outpatient physician and also inform the patient – for example, “We saw some concerns about your diabetes while you were in the hospital, and this is really something that should be looked at when you’re recovered and feeling better from the rest of your health standpoint” – rather than making a diabetes medication change while the person is acutely ill or recovering from illness, said Dr. Anderson, from Beth Israel Deaconess Medical Center and Harvard Medical School, Boston.

The researchers also found an “unexpected” significant decrease in 30-day mortality in the patients with intensified diabetes treatment, which was probably because of confounding that was not accounted for, Dr. Anderson speculated, since clinical trials have consistently shown that benefits from diabetes medications take a longer time to show an effect.
 

‘Important study,’ but lacked newer meds

This is an “important” study for primary care and in-hospital physicians that shows that “hospitalization is really not the time and the place” to intensify diabetes medication, Rozalina G. McCoy, MD, coauthor of an invited commentary, told this news organization in an interview.

“While overcoming treatment inertia is important, [it should be] done appropriately, so that we don’t overtreat patients,” Dr. McCoy, of the Mayo Clinic in Rochester, Minn., stressed.

The very low rate of persistence of taking intensified medications is a major finding, she agreed. Hospitalized patients “are not in their usual state of health, so if we make long-term treatment decisions based on their acute abnormal situation, that may not be appropriate.”

However, patients with high A1c may benefit from a change at hospital discharge rather than when they see their primary care provider, with the caveat that they need close follow-up as an outpatient.

The study emphasizes the “need for longitudinal patient care rather than episodic patches,” according to Dr. McCoy.

For example, a patient who is hospitalized for a chronic obstructive pulmonary disease or asthma exacerbation may be receiving steroids that cause high blood glucose levels but as soon as they’re done with their steroid course, blood glucose will decrease, so the “need for close outpatient follow-up is very important.”

One limitation of the current work is that an earlier study in the same population by the research group showed that 49% of patients whose treatment regimens were intensified had limited life expectancy or were at or below their A1c goal, so they would not have benefited from the stepped-up treatment, she noted.

Another limitation is that the findings cannot be generalized to women or younger patients, or to patients treated with glucagonlike peptide 1 (GLP-1)–receptor agonists or sodium-glucose cotransporter 2 (SGLT2) inhibitors.

The study patients were seen in the U.S. Veterans Health Administration health system when these newer agents were not used. Three-quarters of patients received intensified treatment with sulfonylurea or insulin, and only one patient received a new GLP-1–receptor agonist.

Ideally, Dr. McCoy said, patients should have been prescribed a GLP-1–receptor agonist if they had atherosclerotic cardiovascular disease or kidney disease, or an SGLT2 inhibitor if they had kidney disease or heart failure, which may have led to different results, and would need to be determined in further study.

Dr. Anderson agreed that “SGLT2 inhibitors and GLP1 agonists are broadly much safer than the older diabetes medicines, at least when it comes to risk of hypoglycemia, and may have more clear benefits in heart disease and mortality. So I would not want to extrapolate our findings to those new classes,” he said. “A similar set of studies would need to be done.”
 

Study rationale and findings

Hospitalized older adults with diabetes commonly have transiently elevated blood glucose levels that might lead clinicians to discharge them from hospital with a prescription for more intensive diabetes medications than they were on before they were hospitalized, but it is not clear if these diabetes medication changes would improve outcomes.

To investigate this, the researchers analyzed data from patients with diabetes who were 65 and older and hospitalized for common medical conditions in VHA hospitals during January 2011–September 2016, and then discharged to the community.

They excluded patients who were hospitalized for things that require immediate change in diabetes treatment and patients who were using insulin before their hospitalization (because instructions to modify insulin dosing frequently don’t have a new prescription).

The researchers identified 28,198 adults with diabetes who were not on insulin and were hospitalized in the VHA health system for heart failure (18%), coronary artery disease (13%), chronic obstructive pulmonary disease (10%), pneumonia (9.6%), and urinary tract infection (7.5%), and less often and not in decreasing order, for acute coronary syndrome, arrhythmia, asthma, chest pain, conduction disorders, heart valve disorders, sepsis, skin infection, stroke, and transient ischemic attack.

Of these patients, 2,768 patients (9.8%) received diabetes medication intensification, and the researchers matched 2,648 of these patients with an equal number of patients who did not receive this treatment intensification.

The patients in each group had a mean age of 73 and 98.5% were male; 78% were White.

They had a mean A1c of 7.9%. Most were receiving sulfonylurea (43%) or metformin (39%), and few were receiving thiazolidinediones (4.1%), alpha-glucosidase inhibitors (2.7%), dipeptidyl peptidase 4 inhibitors (2.0%), or other types of diabetes drugs (0.1%).

Of the 2,768 patients who received intensified diabetes medication, most received a prescription for insulin (51%) or sulfonylurea (23%).

In the propensity-matched cohort, patients with intensified diabetes medication had a higher rate of severe hypoglycemia at 30 days (1% vs. 0.5%), which translated into a significant twofold higher risk (hazard ratio, 2.17).

The rates of severe hypoglycemia at 1 year were similar in both groups (3.1% and 2.9%).

The incidence of severe hyperglycemia was the same in both groups at 30 days (0.3%) and 1 year (1.3%).

In secondary outcomes, at 1 year, 48% of new oral diabetes medications and 39% of new insulin prescriptions were no longer being filled.

Overall, patients who were discharged with intensified diabetes medication were significantly less likely to die within 30 days than the other patients (1.3% vs. 2.4%; HR, 0.55).

However, this mortality benefit was found only in the subgroup of 2,524 patients who had uncontrolled diabetes when they were admitted to hospital (A1c >7.5%; mean A1c, 9.1%), and not in the propensity-matched subgroup of 2,672 patients who had controlled diabetes then (A1c up to 7.5%; mean A1c, 6.8%).

There was no significant difference in 1-year mortality in patients with versus without intensified treatment (15.8% vs. 17.8%).

There were also no significant between-group difference in rates of hospital readmission at 30 days (roughly 17%) or 1 year (roughly 51%).

The decreases in mean A1c from hospital discharge to 1 year later were also the same in both groups (going from 7.9% to 7.7%).

The study was funded by grants from the National Institute on Aging and the American College of Cardiology. Dr. Anderson has no relevant financial disclosures. Dr. McCoy reported receiving grants from the National Institute of Diabetes and Digestive and Kidney Diseases, AARP, and the Patient-Centered Outcomes Research Institute outside the submitted work.

Agents that form the sodium-glucose cotransporter 2 inhibitor class – including canagliflozin (Invokana), dapagliflozin (Farxiga), and empagliflozin (Jardiance) – have show remarkably consistent cardiovascular efficacy and safety for treating patients with heart failure, chronic kidney disease, and higher-risk patients with type 2 diabetes.

But despite an essential role now established for drugs in the SGLT2 inhibitor class for patients with heart failure with reduced ejection fraction, progressive renal dysfunction, or – most recently – patients with heart failure with preserved ejection fraction, the scope may be less clear when using these agents in patients with type 2 diabetes because they fall across a broad spectrum of risk for cardiorenal disease.

“What makes patients with type 2 diabetes distinct from other patients in whom SGLT2 inhibitors have been studied, such as patients with heart failure, is that they have a much wider spectrum of risk. Low-risk patients with type 2 diabetes were not included in the SGLT2 inhibitor trials. Defining risk in patients with type 2 diabetes has the potential to inform prioritization” for treatment with an SGLT2 inhibitor, explained David D. Berg, MD, who has led one effort to develop risk scores that can risk-stratify patients with type 2 diabetes based on their vulnerability to incident heart failure and hospitalization for these episodes,

The hefty cost for these drugs, with retail prices that run over $6,000 annually for the most widely used and most potent agents in the class, has spurred researchers to try to find cost-effective ways to identify patients with type 2 diabetes who stand to benefit most from taking an SGLT2 inhibitor.
 

‘Cost must be considered’

“Cost must be considered, and at this point it’s probably more responsible on a societal level to advise using SGLT2 inhibitors mainly in patients [with type 2 diabetes] with compelling indications,” said Silvio Inzucchi, MD, professor and director of the Yale Medicine Diabetes Center in New Haven, Conn. Dr. Inzucchi added, however, that “I can easily foresee a day when these agents are considered foundational therapy for all patients with type 2 diabetes, after they go generic and cost is not a major issue. I’m starting to lean toward this very simplified approach, but the costs are prohibitive at this time.”

“If the SGLT2 inhibitors were available at a low cost, I’d argue that they should be used in all patients with type 2 diabetes who have no contraindications or tolerability issues; but we live in a world where they are not yet low cost,” agreed Mikhail N. Kosiborod, MD, a cardiologist and codirector of the Cardiometabolic Center of Excellence at Saint Luke’s Mid-America Heart Institute in Kansas City, Mo.

“We can’t give SGLT2 inhibitors to everyone with type 2 diabetes right now because that would be too costly; these agents are so expensive. You start by targeting the patients with the highest risk” for incident heart failure, said Ambarish Pandey, MD, a cardiologist at the University of Texas Southwestern Medical Center, Dallas.

The spotlight the SGLT2 inhibitor class has received, based on its unexpectedly potent efficacy in cutting rates of acute heart failure episodes in patients with type 2 diabetes, has also sharply raised the profile of this complication of type 2 diabetes, an outcome that until recently many clinicians had largely ignored, overshadowed by a focus on adverse outcomes from atherosclerotic cardiovascular disease such as MIs and strokes.

“Results from the SGLT2 inhibitor trials have reignited interest in the relationship between type 2 diabetes and heart failure and have started to shift the mindset of clinicians toward thinking about reducing both atherothrombotic risk and heart failure risk in patients with type 2 diabetes,” said Dr. Berg, a cardiologist at Brigham and Women’s Hospital in Boston.

“Prior to the SGLT2 inhibitor trials, heart failure was on the radar of diabetes clinicians only as something to watch for as a potential side effect of certain glucose-lowering therapies. Now that there are therapies that can lower heart failure hospitalization, it’s made us think more about heart failure, how common it is in patients with type 2 diabetes, and what can we do to lower this risk,” commented Alice Y.Y. Cheng, MD, a diabetes specialist at the University of Toronto.
 

Banking on biomarkers

Risk scores for assessing the likelihood of people developing incident heart failure date back more than a decade. More recent efforts have focused on patients with type 2 diabetes, starting with scores that relied entirely on clinical markers of risk such as prior heart failure, established coronary artery disease, and chronic kidney disease. Reports of two of these validated scores appeared in 2019, one from a team led by Dr. Berg and associates in 2019, and a second score developed by Dr. Pandey and associates.

More recently, both research teams behind these two scores validated newer versions that further refined assessment of patients with diabetes by including biomarkers of incipient heart failure, such as N-terminal of the prohormone brain natriuretic peptide (NT-proBNP). The UT Southwestern group’s biomarker-based score relies on levels of NT-proBNP as well as on levels of high sensitivity troponin T (hsTnT) and C-reactive protein, plus ECG-based assessment of left ventricular hypertrophy to assess risk for incident heart failure. Developers reported in 2021 that this biomarker score could account for 74% (C-statistic) of the 5-year risk for heart failure among patients with diabetes.

The biomarker-based score devised by Dr. Berg and associates, relies on NT-proBNP, hsTnT, and a history of heart failure to predict the risk for a future hospitalization for heart failure. They reported in Diabetes Care that in validation testing this score accounted for 84% of the risk.

“I’m hopeful that both our original clinically-based risk score and our new biomarker-based score will be endorsed by professional society guidelines. The intent of the biomarker-based score is not to replace the clinical one,” Dr. Berg stressed in an interview. But he acknowledged that it uses biomarker values that currently are not routinely collected in U.S. practice. Biomarkers like NT-proBNP “are highly associated with future heart failure risk, but are not yet routinely assessed,” he said. Because of this, “widespread adoption of the [biomarker] risk tool will require some education.”

It may also require some sort of preliminary screening to determine the appropriateness of using it in a specific patient because of the relative expense of a test for NT-proBNP.

A Texas two-step process

“We can’t perform a [NT-proBNP] test on every patient with type 2 diabetes because cost is a huge barrier,” with a U.K. price of roughly £28 (about $40) per test, commented Naveed Sattar, MD, PhD, professor of metabolic medicine at the University of Glasgow. “NT-proBNP is the best biomarker by far to predict risk” for heart failure,” but “it’s too expensive. It’s not going to happen in everyone,” he said in an interview. He suggested taking a two-step approach to identify patients to test for NT-proBNP based on clinical measures like blood pressure, weight and height, lipid levels and renal function and the presence of suggestive symptoms like dyspnea, fatigue, and peripheral edema, an argument he recently spelled out in detail in an editorial he coauthored.

“More work is needed to define which patients would usefully have cardiac biomarkers measured,” Dr. Sattar wrote with his associate.

Two-step is the approach used in routine practice by clinicians at UT Southwestern Medical Center. “We screen all patients with type 2 diabetes and no diagnosed heart failure who are not already on an SGLT2 inhibitor” using their 2019 screening tool, called the WATCH-DM Risk score, said Dr. Pandey. Patients flagged at high risk by their clinical score receive an SGLT2 inhibitor (presuming no contraindications). The remaining patients with low or intermediate risk may then undergo biomarker-based assessment to find additional patients who warrant SGLT2 inhibitor treatment, he said in an interview.

Often, a record of the most important biomarker, NT-proBNP, is already in the patient’s record and less than a year old, in which case clinicians use that value. An NT-proBNP level of at least 125 pg/mL indicates increased risk in people with a body mass index of less than 30 kg/m², while for those with higher body mass indexes clinicians at Southwestern apply a threshold for higher risk of at least 100 pg/mL.

In addition to starting those patients on an SGLT2 inhibitor, the Southwestern protocol calls for intensified efforts at weight loss and improved fitness to further lower incident heart failure risk, and they are also considering targeting treatment with a glucagonlike peptide–1 receptor agonist to these patients as well. They have a research protocol in place, called WATCH-DM, that will prospectively assess the efficacy of this strategy.

Despite the cost, others also believe that the time is right for biomarker-based tests to boost access to the benefits that treatment with SGLT2 inhibitors can give patients with type 2 diabetes.

“In theory it’s reasonable” to use a risk score like the recent one reported by Dr. Berg and coauthors, said Vanita R. Aroda, MD, an endocrinologist and director of diabetes clinical research at Brigham and Women’s Hospital in Boston. “We need to pay attention to heart failure as an outcome and use risk stratification” to decide which patients with type 2 diabetes but without established cardiovascular disease warrant treatment with an SGLT2 inhibitor, she said in an interview. “Given the data, we need more concrete recommendations” from medical societies on how to reasonably use biomarkers and imaging to identify patients with type 2 diabetes who are at increased risk for heart failure and hence would benefit from treatment. “This should be of high interest to guidelines committees,” she added.

The earlier version of Dr. Berg’s score, based exclusively on clinical observations and conventional measures like estimated glomerular filtration rate and urinary creatinine to albumin ratio, had overlap with established criteria for starting treatment with an SGLT2 inhibitor, such as the presence of chronic kidney disease, she noted. “A biomarker-based score may provide the additional level of discrimination needed to characterize risk and potential benefit.”
 

Asymptomatic diabetic cardiomyopathy

Dr. Aroda and several coauthors recently published a review that describes a subset of patients with type 2 diabetes who might get picked up by intensified screening for heart failure risk: those with asymptomatic diabetic cardiomyopathy, a clinical state that they said represents patients with stage B heart failure based on the new Universal Definition and Classification of Heart Failure. Until recently, these patients with type 2 diabetes and asymptomatic cardiomyopathy have mostly gone unrecognized.

A recent report from Dr. Pandey and associates reviewed records from 2,900 U.S. patients with diabetes and no symptoms who had been included in any of three cohort studies and found echocardiographic evidence of early-stage cardiomyopathy in as many as two-thirds. In an editorial about this report, Dr. Aroda and coauthors called these patients a potential “window of opportunity for prevention and treatment of heart failure.”

“There is evidence of structural cardiac changes that progress through the stages of heart failure,” and starting treatment with an SGLT2 inhibitor during an earlier stage can potentially slow or prevent this progression and thereby limit future functional decline, Dr. Aroda said.

Dr. Sattar agreed. Type 2 diabetes appears to help cause “fluid derangements” and abnormal hemodynamics that produces cardiac stress, changes in heart structure, and adverse remodeling of the heart, a process that “some call cardiomyopathy,” which is exacerbated by other pathologic forces that are also often present in these patients such as obesity and hypertension. SGLT2 inhibitors can help these patients by producing “reverse remodeling of the heart.”

“This process was neglected because for many years our focus was on ischemic heart disease in patients with type 2 diabetes. It was there in plain sight, but we were missing it,” explained Dr. Sattar. Having agents from the SGLT2 inhibitor class “has allowed us to better understand this mechanism.”

The SGLT2 inhibitors are “absolutely the driving reason” why the diabetes–heart failure link has become so important, said Dr. Inzucchi. Having drugs that reduce heart failure risk provided clinicians with a tool that has “changed our mindset.”

“Heart failure prevention has been largely neglected in patients with type 2 diabetes. Reprioritizing heart failure prevention to first and foremost among patients with type 2 diabetes is long overdue,” commented Gregg C. Fonarow, MD, professor and chief of cardiology at the University of California, Los Angeles.
 

Clinicians don’t like risk scores

Will systematic screening for heart failure risk in selected patients with type 2 diabetes take hold, and with it expanded and better-targeted use of SGLT2 inhibitors?

“I hope so,” said Dr. Kosiborod, but one challenge is that “for the most part clinicians don’t like using risk scores.” Only a few have ever been widely incorporated into practice; mostly they become tools for research. Plus, SGLT2 inhibitor uptake has in general been slow to catch on, which Dr. Kosiborod blames primarily on clinical inertia, a pervasive issue that has also hampered optimal use of drugs as commonplace as statins, ACE inhibitors, and angiotensin-receptor blockers.

“Given the avalanche of positive data, uptake of SGLT2 inhibitors will continue to improve and accelerate; but unfortunately, unless something dramatic happens we’ll likely see their continued underuse for several more years,” he predicted. “Designing better systems of care that prioritize prevention are absolutely needed to improve implementation of effective therapies, including SGLT2 inhibitors.”

Despite their underuse the SGLT2 inhibitor class has, in just 6 years since results from the EMPA-REG OUTCOME trial came out and launched the current treatment era, transformed thinking about the risk that heart failure poses to patients with type 2 diabetes and the need to manage this risk.

“I thank the SGLT2 inhibitors for raising awareness of heart failure risk in patients with diabetes,” and for giving clinicians a new way to mitigate this risk, said Dr. Cheng.

Agents that form the sodium-glucose cotransporter 2 inhibitor class – including canagliflozin (Invokana), dapagliflozin (Farxiga), and empagliflozin (Jardiance) – have show remarkably consistent cardiovascular efficacy and safety for treating patients with heart failure, chronic kidney disease, and higher-risk patients with type 2 diabetes.

But despite an essential role now established for drugs in the SGLT2 inhibitor class for patients with heart failure with reduced ejection fraction, progressive renal dysfunction, or – most recently – patients with heart failure with preserved ejection fraction, the scope may be less clear when using these agents in patients with type 2 diabetes because they fall across a broad spectrum of risk for cardiorenal disease.

“What makes patients with type 2 diabetes distinct from other patients in whom SGLT2 inhibitors have been studied, such as patients with heart failure, is that they have a much wider spectrum of risk. Low-risk patients with type 2 diabetes were not included in the SGLT2 inhibitor trials. Defining risk in patients with type 2 diabetes has the potential to inform prioritization” for treatment with an SGLT2 inhibitor, explained David D. Berg, MD, who has led one effort to develop risk scores that can risk-stratify patients with type 2 diabetes based on their vulnerability to incident heart failure and hospitalization for these episodes,

The hefty cost for these drugs, with retail prices that run over $6,000 annually for the most widely used and most potent agents in the class, has spurred researchers to try to find cost-effective ways to identify patients with type 2 diabetes who stand to benefit most from taking an SGLT2 inhibitor.
 

‘Cost must be considered’

“Cost must be considered, and at this point it’s probably more responsible on a societal level to advise using SGLT2 inhibitors mainly in patients [with type 2 diabetes] with compelling indications,” said Silvio Inzucchi, MD, professor and director of the Yale Medicine Diabetes Center in New Haven, Conn. Dr. Inzucchi added, however, that “I can easily foresee a day when these agents are considered foundational therapy for all patients with type 2 diabetes, after they go generic and cost is not a major issue. I’m starting to lean toward this very simplified approach, but the costs are prohibitive at this time.”

“If the SGLT2 inhibitors were available at a low cost, I’d argue that they should be used in all patients with type 2 diabetes who have no contraindications or tolerability issues; but we live in a world where they are not yet low cost,” agreed Mikhail N. Kosiborod, MD, a cardiologist and codirector of the Cardiometabolic Center of Excellence at Saint Luke’s Mid-America Heart Institute in Kansas City, Mo.

“We can’t give SGLT2 inhibitors to everyone with type 2 diabetes right now because that would be too costly; these agents are so expensive. You start by targeting the patients with the highest risk” for incident heart failure, said Ambarish Pandey, MD, a cardiologist at the University of Texas Southwestern Medical Center, Dallas.

The spotlight the SGLT2 inhibitor class has received, based on its unexpectedly potent efficacy in cutting rates of acute heart failure episodes in patients with type 2 diabetes, has also sharply raised the profile of this complication of type 2 diabetes, an outcome that until recently many clinicians had largely ignored, overshadowed by a focus on adverse outcomes from atherosclerotic cardiovascular disease such as MIs and strokes.

“Results from the SGLT2 inhibitor trials have reignited interest in the relationship between type 2 diabetes and heart failure and have started to shift the mindset of clinicians toward thinking about reducing both atherothrombotic risk and heart failure risk in patients with type 2 diabetes,” said Dr. Berg, a cardiologist at Brigham and Women’s Hospital in Boston.

“Prior to the SGLT2 inhibitor trials, heart failure was on the radar of diabetes clinicians only as something to watch for as a potential side effect of certain glucose-lowering therapies. Now that there are therapies that can lower heart failure hospitalization, it’s made us think more about heart failure, how common it is in patients with type 2 diabetes, and what can we do to lower this risk,” commented Alice Y.Y. Cheng, MD, a diabetes specialist at the University of Toronto.
 

Banking on biomarkers

Risk scores for assessing the likelihood of people developing incident heart failure date back more than a decade. More recent efforts have focused on patients with type 2 diabetes, starting with scores that relied entirely on clinical markers of risk such as prior heart failure, established coronary artery disease, and chronic kidney disease. Reports of two of these validated scores appeared in 2019, one from a team led by Dr. Berg and associates in 2019, and a second score developed by Dr. Pandey and associates.

More recently, both research teams behind these two scores validated newer versions that further refined assessment of patients with diabetes by including biomarkers of incipient heart failure, such as N-terminal of the prohormone brain natriuretic peptide (NT-proBNP). The UT Southwestern group’s biomarker-based score relies on levels of NT-proBNP as well as on levels of high sensitivity troponin T (hsTnT) and C-reactive protein, plus ECG-based assessment of left ventricular hypertrophy to assess risk for incident heart failure. Developers reported in 2021 that this biomarker score could account for 74% (C-statistic) of the 5-year risk for heart failure among patients with diabetes.

The biomarker-based score devised by Dr. Berg and associates, relies on NT-proBNP, hsTnT, and a history of heart failure to predict the risk for a future hospitalization for heart failure. They reported in Diabetes Care that in validation testing this score accounted for 84% of the risk.

“I’m hopeful that both our original clinically-based risk score and our new biomarker-based score will be endorsed by professional society guidelines. The intent of the biomarker-based score is not to replace the clinical one,” Dr. Berg stressed in an interview. But he acknowledged that it uses biomarker values that currently are not routinely collected in U.S. practice. Biomarkers like NT-proBNP “are highly associated with future heart failure risk, but are not yet routinely assessed,” he said. Because of this, “widespread adoption of the [biomarker] risk tool will require some education.”

It may also require some sort of preliminary screening to determine the appropriateness of using it in a specific patient because of the relative expense of a test for NT-proBNP.

A Texas two-step process

“We can’t perform a [NT-proBNP] test on every patient with type 2 diabetes because cost is a huge barrier,” with a U.K. price of roughly £28 (about $40) per test, commented Naveed Sattar, MD, PhD, professor of metabolic medicine at the University of Glasgow. “NT-proBNP is the best biomarker by far to predict risk” for heart failure,” but “it’s too expensive.

“I hope so,” said Dr. Kosiborod, but one challenge is that “for the most part clinicians don’t like using risk scores.” Only a few have ever been widely incorporated into practice; mostly they become tools for research. Plus, SGLT2 inhibitor uptake has in general been slow to catch on, which Dr. Kosiborod blames primarily on clinical inertia, a pervasive issue that has also hampered optimal use of drugs as commonplace as statins, ACE inhibitors, and angiotensin-receptor blockers.

“Given the avalanche of positive data, uptake of SGLT2 inhibitors will continue to improve and accelerate; but unfortunately, unless something dramatic happens we’ll likely see their continued underuse for several more years,” he predicted. “Designing better systems of care that prioritize prevention are absolutely needed to improve implementation of effective therapies, including SGLT2 inhibitors.”

Despite their underuse the SGLT2 inhibitor class has, in just 6 years since results from the EMPA-REG OUTCOME trial came out and launched the current treatment era, transformed thinking about the risk that heart failure poses to patients with type 2 diabetes and the need to manage this risk.

“I thank the SGLT2 inhibitors for raising awareness of heart failure risk in patients with diabetes,” and for giving clinicians a new way to mitigate this risk, said Dr. Cheng.

Dr. Berg has been a consultant to AstraZeneca, and received research grant support to his institution from AstraZeneca and Pfizer. Dr. Cheng has received personal fees from multiple pharmaceutical companies. Dr. Kosiborod has been an adviser and consultant to multiple pharmaceutical companies; has received research grants from AstraZeneca and Boehringer Ingelheim; and has received other research support from AstraZeneca. Dr. Pandey has been an adviser to Roche Diagnostics; has received nonfinancial support from Pfizer and Merck; and has received research support from Gilead Sciences, Myovista, and Applied Therapeutics. Dr. Sattar has received consulting honoraria from multiple pharmaceutical companies, and has received grant support from Boehringer Ingelheim, Roche Diagnostics, and Novartis. Dr. Aroda has been a consultant for several pharmaceutical companies; has a spouse employed with Janssen; and has received research support (institutional contracts) from multiple pharmaceutical companies. Dr. Fonarow has been a consultant to several pharmaceutical companies.

Lupin Pharmaceuticals is recalling all batches of irbesartan tablets USP 75 mg, 150 mg, and 300 mg and irbesartan and hydrochlorothiazide (HCTZ) tablets USP 150 mg/12.5 mg and 300 mg/12.5 mg because of the potential presence of the N-nitrosoirbesartan impurity.

“As part of Lupin’s ongoing assessment, analysis revealed that certain tested active pharmaceutical ingredient (API) batches (but not finished product batches) were above the specification limit for the impurity, N-nitrosoirbesartan,” the company said in a news release posted on the U.S. Food and Drug Administration’s website. It notes that the impurity is a “probable human carcinogen.”

Lupin discontinued the marketing of irbesartan and irbesartan/HCTZ tablets on Jan. 7, 2021. It says it “has received no reports of illness that appear to relate to this issue” and is issuing the recall out of “an abundance of caution.”

The company, however, goes on to note that from Oct. 8, 2018 (the earliest date of shipment from the manufacturing site of any of the affected batches) to September 30 of this year, Lupin received four reports of illness from irbesartan and 0 reports from irbesartan/HCTZ.

Irbesartan is an angiotensin II receptor blocker indicated for treatment of hypertension in patients with type 2 diabetes, elevated serum creatinine, and proteinuria.

Irbesartan/HCTZ tablets include irbesartan and hydrochlorothiazide, a thiazide diuretic, indicated for hypertension in patients not adequately controlled with monotherapy or as an initial therapy in patients likely to need multiple drugs to achieve blood pressure goals.

Lupin is notifying wholesalers, distributors, and retail outlets to immediately discontinue sales of the affected product lots and return them to the company. Specific lot numbers can be found here.

The company is advising patients to continue taking their medication and to contact their pharmacist, physician, or health care professional for advice regarding an alternative treatment.

Patients and physicians are also advised to report any adverse events or side effects related to the affected products to MedWatch, the U.S. Food and Drug Administration’s Safety Information and Adverse Event Reporting program.

Daily exposure to phthalates, which are synthetic chemicals founds in many consumer products, may lead to hundreds of thousands of early deaths each year among older adults in the United States, according to a new study published Oct. 12, 2021, in the peer-reviewed journal Environmental Pollution.

The chemicals are found in hundreds of types of products, including children’s toys, food storage containers, makeup, perfume, and shampoo. In the study, those with the highest levels of phthalates had a greater risk of death from any cause, especially heart disease.

“This study adds to the growing database on the impact of plastics on the human body and bolsters public health and business cases for reducing or eliminating the use of plastics,” Leonardo Trasande, MD, the lead author and a professor of environmental medicine and population health at New York University Langone Health, told CNN.

Dr. Trasande and colleagues measured the urine concentration of phthalates in more than 5,000 adults aged 55-64 and compared the levels with the risk of early death over an average of 10 years. The research team controlled for preexisting heart diseases, diabetes, cancer, poor eating habits, physical activity, body mass, and other known hormone disruptors such as bisphenol A, or BPA, an industrial chemical that’s been used since the 1950s to make certain plastics and resins, according to the Mayo Clinic

The research team found that phthalates could contribute to 91,000-107,000 premature deaths per year in the United States. These early deaths could cost the nation $40 billion to $47 billion each year in lost economic productivity.

Phthalates interrupt the body’s endocrine system and hormone production. Previous studies have found that the chemicals are linked with developmental, reproductive, and immune system problems, according to NYU Langone Health. They’ve also been linked with asthma, childhood obesity, heart issues, and cancer.

“These chemicals have a rap sheet,” Dr. Trasande told CNN. “And the fact of the matter is that when you look at the entire body of evidence, it provides a haunting pattern of concern.”

Phthalates are often called “everywhere chemicals” because they are so common, CNN reported. Also called “plasticizers,” they are added to products to make them more durable, including PVC plumbing, vinyl flooring, medical tubing, garden hoses, food packaging, detergents, clothing, furniture, and automotive materials.

People are often exposed when they breathe contaminated air or consume food that comes into contact with the chemical, according to the Centers for Disease Control and Prevention. Children may be exposed by touching plastic items and putting their hands in their mouth.

Dr. Trasande told CNN that it’s possible to lessen exposure to phthalates and other endocrine disruptors such as BPA by using unscented lotions, laundry detergents, and cleaning supplies, as well as substituting glass, stainless steel, ceramic, and wood for plastic food storage.

“First, avoid plastics as much as you can. Never put plastic containers in the microwave or dishwasher, where the heat can break down the linings so they might be absorbed more readily,” he said. “In addition, cooking at home and reducing your use of processed foods can reduce the levels of the chemical exposures you come in contact with.”

Recent literature features new descriptions of myocarditis linked to the two available mRNA vaccines against SARS-CoV-2. They tell a story largely consistent with experience to date, and support what might be its most useful public health message: The associated myocarditis is usually mild and self-limiting, and is far less likely to occur than myocarditis or death in unvaccinated people with COVID-19.

In line with previous research, the new analyses suggest the myocarditis – with onset usually a few days to a week after injection – has an overall incidence that ranges from less than 1 to perhaps 3 per 100,000 people who received at least one of the full mRNA-vaccine regimen’s two injections. Also, as in earlier studies, the incidence climbed higher – sometimes sharply – in certain groups by age and sex, particularly in young men and older male teens.

The new studies “are confirmatory, in terms of the risk being low,” but underscore that clinicians still must be wary of myocarditis as a potential complication of the mRNA vaccines, Biykem Bozkurt, MD, PhD, Baylor College of Medicine, Houston, told this news organization.

Dr. Bozkurt, a leading heart failure specialist and researcher, did not contribute to any of the new reports but does study the myocarditis of COVID-19 and was lead author on a recent review of the potential vaccine complication’s features and possible mechanisms.

In the new myocarditis reports, she observed, more than 90% of the cases were mild and “resolved on their own without a major adverse outcome.” Dr. Bozkurt emphasized the need for perspective regarding the risk. For example, the myocarditis associated with SARS-CoV-2 infection is not only more likely than the vaccine-related myocarditis, but it’s also usually far more severe.

Dr. Bozkurt pointed to a recent study in which the mRNA vaccines, compared with no vaccination, appeared to escalate the myocarditis risk by a factor of 3, whereas the risk for myocarditis in SARS-CoV-2 infection was increased 18 times.

In contrast, she observed, the new myocarditis cases reported this week feature a few that are novel or are at least very rare, including the case of a patient who developed cardiogenic shock and another with fulminant myocarditis who died.

The Centers for Disease Control and Prevention in May publicly described the apparent link between myocarditis and the two available mRNA vaccines against SARS-CoV-2: BNT162b2 (Pfizer-BioNTech) and mRNA-1273 (Moderna). The next month, the Food and Drug Administration added a warning about the risk to the labeling.
 

Less than 1 case per 100,000

Fifteen confirmed cases of myocarditis were identified among about 2.4 million members of Kaiser Permanente Southern California aged 18 or older who received at least one injection of the Pfizer or Moderna mRNA vaccines between December 2020 and July 2021, in a report published in JAMA Internal Medicine. The study counted cases up to 10 days after the first or second injection, of which there were 2 and 13, respectively.

All eight patients who received the Pfizer BNT162b2 vaccine and the eight given the Moderna mRNA-1273 vaccine were male with a median age of 25 years (interquartile range, 20-32 years).

“The main takeaway messages from our study are that the incidence of myocarditis after COVID-19 mRNA vaccinations is very low, that this condition is primarily observed in young men within a few days after the second dose, and that most patients recover quickly,” senior author Mingsum Lee, MD, PhD, Kaiser Permanente Los Angeles Medical Center, told this news organization.

“The incidence of vaccine-related myocarditis was significantly lower than rates of COVID-19 hospitalization during the same period and population area,” she added.

The group saw a per-million incidence of 0.8 and 5.8 myocarditis cases in the 10 days after first and second injections, respectively. That made for an incidence of 0.58 per 100,000, or 1 case per 172,414 fully vaccinated adults.

The group also considered a cohort of 1,577,741 unvaccinated people with a median age of 39 years (interquartile range, 28-53 years) during the same period. Of the 75 cases of myocarditis, 52% were in men, they reported.

Comparing the vaccinated and unvaccinated cohorts, they saw a 10-day vaccine-associated myocarditis incidence rate ratio of 0.38 (95% confidence interval, 0.05-1.40; P = .15) after the first dose, and 2.7 (95% CI, 1.4-4.8; P = .004) after the second dose.

In a comparison of the vaccinated group with itself using data from a 10-day period in the previous year, the corresponding myocarditis IRRs were 1.0 (P > .99) and 3.3 (P = .03), respectively.

Dr. Lee said none of the 15 patients required admission to an intensive care unit. “All patients with myocarditis responded well to treatment and felt better quickly,” she noted.

Myocarditis after an mRNA vaccine injection is rare and, Dr. Lee said emphatically, and “the benefits of the COVID-19 vaccine greatly outweigh the risks.”
 

Sex- and age-stratified rates

In a separate analysis of 5,442,696 people given a first dose of the Pfizer BNT162b2 vaccine and 5,125,635 given a second dose, there were 142 cases of myocarditis with onset 21 days after dose 1 and 30 days after dose 2. Of those cases, 136 were documented as “definite or probable” in an Israeli Ministry of Health database that covered up to the end of May 2021.

There were also 40 cases among vaccinated people seen after the 30-day window, which were considered not related to the vaccination, and 101 cases among unvaccinated people; of the latter, 29 had confirmed diagnoses of COVID-19.

Of the 136 people with definite or probable cases, the myocarditis was “generally mild” in 129 and usually resolved on its own, notes the report on the study, published in the New England Journal of Medicine, with lead author Dror Mevorach, MD, Hadassah-Hebrew University Medical Center, Jerusalem.

The estimated myocarditis incidence after a second such vaccine dose across the entire Israeli population, based on the current study, was about one per 26,000 males and one per 218,000 females, the group writes. Those figures compare with one case per 10,857 among “the general unvaccinated population.”

Again, the risk was concentrated among younger men and male adolescents. In an analysis limited to vaccinated people aged 16-19 years, myocarditis in the 21 days after a second mRNA injection was seen in about one of 6,637 males and one of 99,853 females, the group reported.

The standardized incidence ratio of 5.34 (95% CI, 4.48-6.40) after a second injection, across all groups, “was driven mostly by the diagnosis of myocarditis in younger male recipients.” Among that male subgroup, the ratios by age group were 13.60 (95% CI, 9.30-19.20) for 16-19 years, 8.53 (95% CI, 5.57-12.50) for 20-24 years, and 6.96 (95% CI, 4.25-10.75) for 25-29 years.

Among people who received a second injection, compared with unvaccinated people, the 30-day rate ratio was 2.35 (95% CI, 1.10-5.02). Again, the effect was concentrated in males aged 16-19 years. Among them, the myocarditis rate ratios in the 30 days after a second mRNA vaccine injection were 8.96 (95% CI, 4.50-17.83) for the 16-19 years group, 6.13 (95% CI, 3.16-11.88) for the 20-24 group, and 3.58 (95% CI, 1.82-7.01) for 25-29 years.

Most of the patients with myocarditis showed “significant clinical improvement,” with a mean hospitalization time of only 3-4 days, the report notes. Treatment consisted of nonsteroidal anti-inflammatory drugs “with or without colchicine for presumed pericardial inflammation.”

However, seven patients (4.9%) developed important complications, including left-ventricular dysfunction, ventricular arrhythmias, and heart failure. Among them was a 22-year-old patient who died of fulminant myocarditis within 24 hours of diagnosis, the group wrote.
 

From an Israeli health care organization

Published by the same journal as the study by Dr. Menvorach and associates, an analysis of a separate database showed largely consistent findings among patients in the largest of Israel’s four health care organizations charged by the government to administer health services.

The report, with authors led by Guy Witberg, MD, Rabin Medical Center, Petah Tikva, Israel, focused on members of the health care organization aged 16 years or older who had received at least one Pfizer mRNA vaccine dose by the end of May 2021.

The cohorts from the two separate reports surely overlap substantially, as the Ministry of Health analysis from Dr. Mevorach and colleagues derived from a nationwide database, and – as Dr. Witberg and associates wrote – the health care organization providing their data covers 52% of the Israeli population.

Of 2,558,421 vaccinated people in the analysis, of whom 94% received two doses, 54 developed confirmed myocarditis in the 42 days after the first dose. Their median age was 27 years (interquartile range, 21-35 years) and all but three (94%) were male. Of those 54 cases, 41 were considered mild and 12 intermediate in severity, and one was fulminant with the patient in cardiogenic shock, the group writes. In addition, nonsustained ventricular tachycardia and atrial fibrillation developed in 5% and 3% of cases, respectively.

The estimated myocarditis incidence in the 42 days after administration of at least one mRNA vaccine dose was 2.13 per 100,000 vaccinated people. In that group, Dr. Witberg and colleagues note, the corresponding incidences per 100,000 were 4.12 and 0.23 for males and females, respectively.

Also in the current report, incidences per 100,000 vaccinated people aged 16-29 years, by sex, included 5.49 (95% CI, 3.59-7.39) overall, and 10.69 (95% CI, 6.93-14.46) for males (the highest rate in the report).

There was only one case in a female aged 16-29 years, and two cases in females 30 years or older.

Of note, some authors of the current study are also authors on the high-profile report from Noam Barda, MD, and colleagues published in the New England Journal of Medicine, that used the same database to arrive at an mRNA-vaccine-related incidence of myocarditis of 2.7 per 100,000. Eligibility criteria and follow-up time were different in that report, as were case ascertainment criteria.

The myocarditis risk associated with the two mRNA vaccines is small compared with “the morbidity and mortality of COVID-19 infection, in which up to 28% of hospitalized patients showed signs of myocardial injury,” wrote Vinay Guduguntla, MD, University of California, San Francisco, and Mitchell H. Katz, MD, NYC Health + Hospitals, New York, in an editorial accompanying the report from Dr. Lee and associates.

“Randomized clinical trials show that COVID-19 mRNA vaccines represent a safe and effective method of preventing infection,” they stated. “The identification of rare myocarditis does not change clinical decision-making.”

Dr. Bozkurt, who is immediate past president of the Heart Failure Society of America, has disclosed consulting for Bayer and scPharmaceuticals and serving on a clinical events committee for a trial supported by Abbott Pharmaceuticals and on a data and safety monitoring board for a trial supported by Liva Nova Pharmaceuticals. Dr. Lee and the report’s other authors had no disclosures. Dr. Mevorach discloses consulting for Enlivex Therapeutics; disclosures for the other authors are available at NEJM.org. Dr. Witberg said he has no interests to disclose; disclosures for the other authors are available at NEJM.org. Dr. Guduguntla is an editorial fellow and Dr. Katz a deputy editor at JAMA Internal Medicine; neither had disclosures.

All eight patients who received the Pfizer BNT162b2 vaccine and the eight given the Moderna mRNA-1273 vaccine were male with a median age of 25 years (interquartile range, 20-32 years).

“The main takeaway messages from our study are that the incidence of myocarditis after COVID-19 mRNA vaccinations is very low, that this condition is primarily observed in young men within a few days after the second dose, and that most patients recover quickly,” senior author Mingsum Lee, MD, PhD, Kaiser Permanente Los Angeles Medical Center, told this news organization.

“The incidence of vaccine-related myocarditis was significantly lower than rates of COVID-19 hospitalization during the same period and population area,” she added.

The group saw a per-million incidence of 0.8 and 5.8 myocarditis cases in the 10 days after first and second injections, respectively. That made for an incidence of 0.58 per 100,000, or 1 case per 172,414 fully vaccinated adults.

The group also considered a cohort of 1,577,741 unvaccinated people with a median age of 39 years (interquartile range, 28-53 years) during the same period. Of the 75 cases of myocarditis, 52% were in men, they reported.

Comparing the vaccinated and unvaccinated cohorts, they saw a 10-day vaccine-associated myocarditis incidence rate ratio of 0.38 (95% confidence interval, 0.05-1.40; P = .15) after the first dose, and 2.7 (95% CI, 1.4-4.8; P = .004) after the second dose.

In a comparison of the vaccinated group with itself using data from a 10-day period in the previous year, the corresponding myocarditis IRRs were 1.0 (P > .99) and 3.3 (P = .03), respectively.

Dr. Lee said none of the 15 patients required admission to an intensive care unit. “All patients with myocarditis responded well to treatment and felt better quickly,” she noted.

Myocarditis after an mRNA vaccine injection is rare and, Dr. Lee said emphatically, and “the benefits of the COVID-19 vaccine greatly outweigh the risks.”
 

Sex- and age-stratified rates

In a separate analysis of 5,442,696 people given a first dose of the Pfizer BNT162b2 vaccine and 5,125,635 given a second dose, there were 142 cases of myocarditis with onset 21 days after dose 1 and 30 days after dose 2. Of those cases, 136 were documented as “definite or probable” in an Israeli Ministry of Health database that covered up to the end of May 2021.

There were also 40 cases among vaccinated people seen after the 30-day window, which were considered not related to the vaccination, and 101 cases among unvaccinated people; of the latter, 29 had confirmed diagnoses of COVID-19.

Of the 136 people with definite or probable cases, the myocarditis was “generally mild” in 129 and usually resolved on its own, notes the report on the study, published in the New England Journal of Medicine, with lead author Dror Mevorach, MD, Hadassah-Hebrew University Medical Center, Jerusalem.

The estimated myocarditis incidence after a second such vaccine dose across the entire Israeli population, based on the current study, was about one per 26,000 males and one per 218,000 females, the group writes. Those figures compare with one case per 10,857 among “the general unvaccinated population.”

Again, the risk was concentrated among younger men and male adolescents. In an analysis limited to vaccinated people aged 16-19 years, myocarditis in the 21 days after a second mRNA injection was seen in about one of 6,637 males and one of 99,853 females, the group reported.

The standardized incidence ratio of 5.34 (95% CI, 4.48-6.40) after a second injection, across all groups, “was driven mostly by the diagnosis of myocarditis in younger male recipients.” Among that male subgroup, the ratios by age group were 13.60 (95% CI, 9.30-19.20) for 16-19 years, 8.53 (95% CI, 5.57-12.50) for 20-24 years, and 6.96 (95% CI, 4.25-10.75) for 25-29 years.

Among people who received a second injection, compared with unvaccinated people, the 30-day rate ratio was 2.35 (95% CI, 1.10-5.02). Again, the effect was concentrated in males aged 16-19 years. Among them, the myocarditis rate ratios in the 30 days after a second mRNA vaccine injection were 8.96 (95% CI, 4.50-17.83) for the 16-19 years group, 6.13 (95% CI, 3.16-11.88) for the 20-24 group, and 3.58 (95% CI, 1.82-7.01) for 25-29 years.

Most of the patients with myocarditis showed “significant clinical improvement,” with a mean hospitalization time of only 3-4 days, the report notes. Treatment consisted of nonsteroidal anti-inflammatory drugs “with or without colchicine for presumed pericardial inflammation.”

However, seven patients (4.9%) developed important complications, including left-ventricular dysfunction, ventricular arrhythmias, and heart failure. Among them was a 22-year-old patient who died of fulminant myocarditis within 24 hours of diagnosis, the group wrote.
 

From an Israeli health care organization

Published by the same journal as the study by Dr. Menvorach and associates, an analysis of a separate database showed largely consistent findings among patients in the largest of Israel’s four health care organizations charged by the government to administer health services.

The report, with authors led by Guy Witberg, MD, Rabin Medical Center, Petah Tikva, Israel, focused on members of the health care organization aged 16 years or older who had received at least one Pfizer mRNA vaccine dose by the end of May 2021.

The cohorts from the two separate reports surely overlap substantially, as the Ministry of Health analysis from Dr. Mevorach and colleagues derived from a nationwide database, and – as Dr. Witberg and associates wrote – the health care organization providing their data covers 52% of the Israeli population.

Of 2,558,421 vaccinated people in the analysis, of whom 94% received two doses, 54 developed confirmed myocarditis in the 42 days after the first dose. Their median age was 27 years (interquartile range, 21-35 years) and all but three (94%) were male. Of those 54 cases, 41 were considered mild and 12 intermediate in severity, and one was fulminant with the patient in cardiogenic shock, the group writes. In addition, nonsustained ventricular tachycardia and atrial fibrillation developed in 5% and 3% of cases, respectively.

The estimated myocarditis incidence in the 42 days after administration of at least one mRNA vaccine dose was 2.13 per 100,000 vaccinated people. In that group, Dr. Witberg and colleagues note, the corresponding incidences per 100,000 were 4.12 and 0.23 for males and females, respectively.

Also in the current report, incidences per 100,000 vaccinated people aged 16-29 years, by sex, included 5.49 (95% CI, 3.59-7.39) overall, and 10.69 (95% CI, 6.93-14.46) for males (the highest rate in the report).

There was only one case in a female aged 16-29 years, and two cases in females 30 years or older.

Of note, some authors of the current study are also authors on the high-profile report from Noam Barda, MD, and colleagues published in the New England Journal of Medicine, that used the same database to arrive at an mRNA-vaccine-related incidence of myocarditis of 2.7 per 100,000. Eligibility criteria and follow-up time were different in that report, as were case ascertainment criteria.

The myocarditis risk associated with the two mRNA vaccines is small compared with “the morbidity and mortality of COVID-19 infection, in which up to 28% of hospitalized patients showed signs of myocardial injury,” wrote Vinay Guduguntla, MD, University of California, San Francisco, and Mitchell H. Katz, MD, NYC Health + Hospitals, New York, in an editorial accompanying the report from Dr. Lee and associates.

“Randomized clinical trials show that COVID-19 mRNA vaccines represent a safe and effective method of preventing infection,” they stated. “The identification of rare myocarditis does not change clinical decision-making.”

Dr. Bozkurt, who is immediate past president of the Heart Failure Society of America, has disclosed consulting for Bayer and scPharmaceuticals and serving on a clinical events committee for a trial supported by Abbott Pharmaceuticals and on a data and safety monitoring board for a trial supported by Liva Nova Pharmaceuticals. Dr. Lee and the report’s other authors had no disclosures. Dr. Mevorach discloses consulting for Enlivex Therapeutics; disclosures for the other authors are available at NEJM.org. Dr. Witberg said he has no interests to disclose; disclosures for the other authors are available at NEJM.org. Dr. Guduguntla is an editorial fellow and Dr. Katz a deputy editor at JAMA Internal Medicine; neither had disclosures.

Recent literature features new descriptions of myocarditis linked to the two available mRNA vaccines against SARS-CoV-2. They tell a story largely consistent with experience to date, and support what might be its most useful public health message: The associated myocarditis is usually mild and self-limiting, and is far less likely to occur than myocarditis or death in unvaccinated people with COVID-19.

In line with previous research, the new analyses suggest the myocarditis – with onset usually a few days to a week after injection – has an overall incidence that ranges from less than 1 to perhaps 3 per 100,000 people who received at least one of the full mRNA-vaccine regimen’s two injections. Also, as in earlier studies, the incidence climbed higher – sometimes sharply – in certain groups by age and sex, particularly in young men and older male teens.

The new studies “are confirmatory, in terms of the risk being low,” but underscore that clinicians still must be wary of myocarditis as a potential complication of the mRNA vaccines, Biykem Bozkurt, MD, PhD, Baylor College of Medicine, Houston, told this news organization.

Dr. Bozkurt, a leading heart failure specialist and researcher, did not contribute to any of the new reports but does study the myocarditis of COVID-19 and was lead author on a recent review of the potential vaccine complication’s features and possible mechanisms.

In the new myocarditis reports, she observed, more than 90% of the cases were mild and “resolved on their own without a major adverse outcome.” Dr. Bozkurt emphasized the need for perspective regarding the risk. For example, the myocarditis associated with SARS-CoV-2 infection is not only more likely than the vaccine-related myocarditis, but it’s also usually far more severe.

Dr. Bozkurt pointed to a recent study in which the mRNA vaccines, compared with no vaccination, appeared to escalate the myocarditis risk by a factor of 3, whereas the risk for myocarditis in SARS-CoV-2 infection was increased 18 times.

In contrast, she observed, the new myocarditis cases reported this week feature a few that are novel or are at least very rare, including the case of a patient who developed cardiogenic shock and another with fulminant myocarditis who died.

The Centers for Disease Control and Prevention in May publicly described the apparent link between myocarditis and the two available mRNA vaccines against SARS-CoV-2: BNT162b2 (Pfizer-BioNTech) and mRNA-1273 (Moderna). The next month, the Food and Drug Administration added a warning about the risk to the labeling.
 

Less than 1 case per 100,000

Fifteen confirmed cases of myocarditis were identified among about 2.4 million members of Kaiser Permanente Southern California aged 18 or older who received at least one injection of the Pfizer or Moderna mRNA vaccines between December 2020 and July 2021, in a report published in JAMA Internal Medicine.

The rapid transition to and reliance on telehealth to manage patients with heart failure during the COVID-19 pandemic does not appear to impact clinical outcomes, according to real-world data.

HF outpatients managed with telehealth visits did not show a significantly higher adjusted risk for subsequent ED visits, hospital admissions, intensive care use, or death at 30 and 90 days, the investigators reported in JACC: Heart Failure.

“Telehealth is safe and effective in probably some of our highest-risk patients who traditionally have needed hands-on, in-person assessment and evaluation – those patients who have heart failure – so we shouldn’t be afraid to use it all the time, not when needed as a minimum,” senior author Brett W. Sperry, MD, said in an interview.

Heart failure is a perfect case example to examine telehealth because the chronic condition not only requires continual assessment and medication adjustments, but HF patients are also particularly vulnerable to complications related to COVID-19 infection, he noted. A small, single-center report on telehealth early in Italy’s outbreak showed fewer HF hospitalizations and similar mortality, compared with in-person visits in 2019 but, overall, few data exist.

The current analysis took a wider sweep, comparing HF patients seen from March 15 to June 15, 2020 with those seen during the same time period in 2018 and 2019 at 16 cardiology clinics in Saint Luke’s Health System, which serves the Kansas City metro area and surrounding suburbs in Missouri and Kansas.

Among 8,263 unique patients and 15,421 visits identified, telehealth was not used in 2018 or 2019 but accounted for 88.5% of visits during the study period in 2020, 70% of which were by telephone and 30% of which were by video.

“We had zero telehealth before March 2020 and basically built an entire telehealth apparatus in a week or 2,” explained Dr. Sperry. “Initially it was a lot of telephone visits while we were getting the video stuff figured out, which is reflected in the paper, and then went to mostly video visits.”

Despite the pandemic, however, more outpatients were seen in 2020 than in 2018 and 2019 (4,063 vs. 3675 and 3,619 patients, respectively). This likely reflects the shift of personnel and resources from hospital duties to outpatient virtual visits, which were strongly recommended by the Heart Failure Society of America and other professional societies to manage patients during the pandemic, he said.

Unadjusted analyses demonstrated fewer ED visits and hospital admissions and more ICU admissions and all-cause mortality in 2020 than in previous years.

A propensity-matched analysis involving 4541 pairs of patients, however, showed admissions to the ED or hospital were lower after the telehealth visits than after in-person visits at 30 days (6.8% vs 10.4%; P < .001) and 90 days (17.9% vs. 23.3%; P < .001).

Among hospitalized patients, there was no difference between telehealth and in-patient visits in ICU admissions at 30 or 90 days. Mortality was also similar at 30 days (0.8% vs. 0.7%; P = .465) and 90 days (2.9% vs. 2.4%; P = .133).

Dr. Sperry said the pendulum has swung since 2020 and that the team is back to seeing most people in person, with about 15% of his clinic visits that day done via video. Standardized quality of life assessments prior to outpatient visits can help triage patients to telehealth in-patient visits, but in-person visits will still be needed for cases with greater acuity, older patients, and those with limited or no access to quality telephone videos or the internet.

“It isn’t for everyone,” Dr. Sperry said. “You’re going to need some kind of hybrid model with both in-person and video visits available and be able to offer both for patients and be able to titrate that as the pandemic changes in the future.”

Ankit Bhatia, MD, an advanced HF cardiologist at Christ Hospital in Cincinnati, who was not part of the study, said in an interview the use of telehealth in 85% of patients may be higher than the norm at most centers but that the study provides much-needed data.

“I’m really appreciative of a study like this because we were all in such a rush last year to get patients seen that very few people thought how could we design a study to really ensure we’re treating our patients within an equipoise with prior practices,” he said.

“The fact that they were able to do that [85%] and demonstrate in a propensity-matched analysis that outcomes were similar really just shows that telehealth is a strategy that we can use well in patients with heart failure to extend our ability to take care of them,” said Dr. Bhatia, a member of the American College of Cardiology Health Care Innovation Council.

Even beyond the pandemic, he said, the trend in health care is for patients to want health care delivered closer to home and for health care systems to become more patient centric. “This accelerated that but what I think this study showed me was that it’s okay to have this be part of my care model and I’m not sacrificing on my patient care if I choose to intersperse telehealth with inpatient visits.”

Besides the inherent limitations of retrospective studies, the authors noted that diagnoses in the study were based on ICD-10 codes and that subsequent ED visits or hospitalizations outside the single system may have been underreported. A further limitation is that they could not identify the cause of death or reasons for hospital encounters.

“Further data are needed to confirm the relative safety of a telehealth strategy in the HF population over a more sustained period of time, although we hypothesize that greater risks would be observed early after telehealth visits, where patients’ acuity might be misjudged,” they wrote.

“I’m really appreciative of a study like this because we were all in such a rush last year to get patients seen that very few people thought how could we design a study to really ensure we’re treating our patients within an equipoise with prior practices,” he said.

“The fact that they were able to do that [85%] and demonstrate in a propensity-matched analysis that outcomes were similar really just shows that telehealth is a strategy that we can use well in patients with heart failure to extend our ability to take care of them,” said Dr. Bhatia, a member of the American College of Cardiology Health Care Innovation Council.

Even beyond the pandemic, he said, the trend in health care is for patients to want health care delivered closer to home and for health care systems to become more patient centric. “This accelerated that but what I think this study showed me was that it’s okay to have this be part of my care model and I’m not sacrificing on my patient care if I choose to intersperse telehealth with inpatient visits.”

Besides the inherent limitations of retrospective studies, the authors noted that diagnoses in the study were based on ICD-10 codes and that subsequent ED visits or hospitalizations outside the single system may have been underreported. A further limitation is that they could not identify the cause of death or reasons for hospital encounters.

“Further data are needed to confirm the relative safety of a telehealth strategy in the HF population over a more sustained period of time, although we hypothesize that greater risks would be observed early after telehealth visits, where patients’ acuity might be misjudged,” they wrote.

The rapid transition to and reliance on telehealth to manage patients with heart failure during the COVID-19 pandemic does not appear to impact clinical outcomes, according to real-world data.

HF outpatients managed with telehealth visits did not show a significantly higher adjusted risk for subsequent ED visits, hospital admissions, intensive care use, or death at 30 and 90 days, the investigators reported in JACC: Heart Failure.

“Telehealth is safe and effective in probably some of our highest-risk patients who traditionally have needed hands-on, in-person assessment and evaluation – those patients who have heart failure – so we shouldn’t be afraid to use it all the time, not when needed as a minimum,” senior author Brett W. Sperry, MD, said in an interview.

Heart failure is a perfect case example to examine telehealth because the chronic condition not only requires continual assessment and medication adjustments, but HF patients are also particularly vulnerable to complications related to COVID-19 infection, he noted. A small, single-center report on telehealth early in Italy’s outbreak showed fewer HF hospitalizations and similar mortality, compared with in-person visits in 2019 but, overall, few data exist.

The current analysis took a wider sweep, comparing HF patients seen from March 15 to June 15, 2020 with those seen during the same time period in 2018 and 2019 at 16 cardiology clinics in Saint Luke’s Health System, which serves the Kansas City metro area and surrounding suburbs in Missouri and Kansas.

Among 8,263 unique patients and 15,421 visits identified, telehealth was not used in 2018 or 2019 but accounted for 88.5% of visits during the study period in 2020, 70% of which were by telephone and 30% of which were by video.

“We had zero telehealth before March 2020 and basically built an entire telehealth apparatus in a week or 2,” explained Dr. Sperry. “Initially it was a lot of telephone visits while we were getting the video stuff figured out, which is reflected in the paper, and then went to mostly video visits.”

Despite the pandemic, however, more outpatients were seen in 2020 than in 2018 and 2019 (4,063 vs. 3675 and 3,619 patients, respectively). This likely reflects the shift of personnel and resources from hospital duties to outpatient virtual visits, which were strongly recommended by the Heart Failure Society of America and other professional societies to manage patients during the pandemic, he said.

Unadjusted analyses demonstrated fewer ED visits and hospital admissions and more ICU admissions and all-cause mortality in 2020 than in previous years.

A propensity-matched analysis involving 4541 pairs of patients, however, showed admissions to the ED or hospital were lower after the telehealth visits than after in-person visits at 30 days (6.8% vs 10.4%; P < .001) and 90 days (17.9% vs. 23.3%; P < .001).

Among hospitalized patients, there was no difference between telehealth and in-patient visits in ICU admissions at 30 or 90 days. Mortality was also similar at 30 days (0.8% vs. 0.7%; P = .465) and 90 days (2.9% vs. 2.4%; P = .133).

Dr. Sperry said the pendulum has swung since 2020 and that the team is back to seeing most people in person, with about 15% of his clinic visits that day done via video. Standardized quality of life assessments prior to outpatient visits can help triage patients to telehealth in-patient visits, but in-person visits will still be needed for cases with greater acuity, older patients, and those with limited or no access to quality telephone videos or the internet.

“It isn’t for everyone,” Dr. Sperry said. “You’re going to need some kind of hybrid model with both in-person and video visits available and be able to offer both for patients and be able to titrate that as the pandemic changes in the future.”
