In patients undergoing transcatheter aortic valve replacement (TAVR), the incidence of leaflet thrombosis was numerically lower in those treated with the anticoagulant edoxaban for 6 months after the procedure than in those who received dual antiplatelet therapy, although the difference was not statistically significant, in the ADAPT-TAVR study.

There was no difference in new cerebral thromboembolism or neurologic/neurocognitive function between the two groups in the study.

Also, there was no significant relation between subclinical leaflet thrombosis and increased risk for cerebral thromboembolism and neurologic dysfunction.

The ADAPT-TAVR trial was presented April 4 at the American College of Cardiology (ACC) 2022 Scientific Session by Duk-Woo Park, MD, Asan Medical Center, Seoul, South Korea. It was simultaneously published online in Circulation.

The Food and Drug Administration has granted approval to Abbott’s Aveir leadless, single-chamber pacemaker system for patients with bradycardia.

In a press release, Abbott said the device has a unique mapping capability that allows interventionists implanting the device to measure electrical signals within the heart to determine the correct placement before final implantation. Aveir is implanted directly into the right ventricle via a catheter.

The company also said Aveir has a battery life that’s up to twice as long as other commercially available leadless pacemakers when following International Association for Standardization (ISO) standard settings. And the device can be retrieved if necessary, the press release said.

“Leadless pacemakers address known complications associated with traditional pacemakers,” Rahul Doshi, MD, director of electrophysiology at Honor Health in Scottsdale, Ariz., said in the press release. “In addition, the Aveir leadless pacemaker brings unique innovations we’ve been seeking, such as the ability to ensure electrical performance before we commit to placement.”

Investigators of the LEADLESS II phase 2 study reported last year on what they called “key design improvements” of the Aveir device compared to the first leadless pacemaker, the discontinued Nanostim. They included a 12% longer battery life, a shorter and wider form factor, a modified docking button that allows for retrievability, a modified delivery system, and an application-specific integrated circuit chip that can support a dual-chamber pacing system in the future.

The study reported that 96% of the 200 enrolled patients met the primary safety endpoint of no serious device-related adverse events at 6 weeks after implantation. A similar percentage achieved therapeutic pacing and sensing amplitude.

The study also reported that interventionists accurately positioned Aveir the first time or with a single repositioning in 96% of cases.

Patients with persistent cognitive impairment months after illness with mild COVID-19 have higher levels of inflammatory markers in their cerebrospinal fluid (CSF). Researchers found elevated levels of CSF immune activation and immunovascular markers in individuals with cognitive postacute sequelae of SARS-CoV-2 infection (PASC). Patients whose cognitive symptoms developed during the acute phase of COVID-19 had the highest levels of brain inflammation.

The findings add to a growing body of evidence that suggests the condition often referred to as “brain fog” has a neurologic basis, said lead author Joanna Hellmuth, MD, MHS, assistant professor of neurology at the University of California, San Francisco Weill Institute of Neurosciences and the UCSF Memory and Aging Center.

The findings will be presented at the 2022 annual meeting of the American Academy of Neurology.
 

Inflammatory response

There are no effective diagnostic tests or treatments for cognitive PASC, which prompted the investigators to study inflammation in patients with the condition. Initial findings were reported earlier in 2022, which showed abnormalities in the CSF in 77% of patients with cognitive impairment. Patients without cognitive impairments had normal CSF.

Extending that work in this new study, researchers studied patients from the Long-term Impact of Infection With Novel Coronavirus (LIINC) study with confirmed SARS-CoV-2 infection who were not hospitalized. They conducted 2-hour neurocognitive interviews and identified 23 people with new, persistent cognitive symptoms (cognitive PASC) and 10 with no cognitive symptoms who served as controls.

All participants underwent additional neurologic examination and neuropsychological testing, and half agreed to a lumbar puncture to allow researchers to collect CSF samples. The CSF was collected a median of 10.2 months after initial COVID symptoms began.

Participants with cognitive PASC had higher median levels of CSF acute phase reactants C-reactive protein (0.007 mg/L vs. 0.000 mg/L; P =.004) and serum amyloid A (0.001 mg/L vs. 0.000 mg/L; P = .001), compared with COVID controls.

The PASC group also had elevated levels of CSF immune activation markers interferon gamma–inducible protein (IP-10), interleukin-8, and immunovascular markers vascular endothelial growth factor-C and VEGFR-1, although the differences with the control group were not statistically significant.

The timing of the onset of cognitive problems was also associated with higher levels of immune activation and immunovascular markers. Patients with brain fog that developed during the acute phase of COVID-19 had higher levels of CSF VEGF-C, compared with patients whose cognitive symptoms developed more than a month after initial COVID symptoms (173 pg/mL vs. 99 pg/mL; P = .048) and COVID controls (79 pg/mL; P = .048).

Acute onset cognitive PASC participants had higher CSF levels of IP-10 (P = .030), IL-8 (P = .048), placental growth factor (P = .030) and intercellular adhesion molecule-1 (P = .045), compared with COVID controls.

Researchers believe these new findings could mean that intrathecal immune activation and endothelial activation/dysfunction may contribute to cognitive PASC and that the mechanisms involved may be different in patients with acute cognitive PASC versus those with delayed onset.

“Our data suggests that perhaps in these people with more acute cognitive changes they don’t have the return to homeostasis,” Dr. Hellmuth said, while patients with delayed onset cognitive PASC had levels more in line with COVID patients who had no cognitive issues.
 

Moving the needle forward

Commenting on the findings, William Schaffner, MD, professor of infectious diseases, Vanderbilt University Medical Center, Nashville, Tenn., said that, while the study doesn’t rule out a possible psychological basis for cognitive PASC, it adds more weight to the biological argument.

“When you have nonspecific symptoms for which specific tests are unavailable,” Dr. Schaffner explained, “there is a natural question that always comes up: Is this principally a biologically induced phenomenon or psychological? This moves the needle substantially in the direction of a biological phenomenon.”

Another important element to the study, Dr. Schaffner said, is that the patients involved had mild COVID.

“Not every patient with long COVID symptoms had been hospitalized with severe disease,” he said. “There are inflammatory phenomenon in various organ systems such that even if the inflammatory response in the lung was not severe enough to get you into the hospital, there were inflammatory responses in other organ systems that could persist once the acute infection resolved.”

Although the small size of the study is a limitation, Dr. Schaffner said that shouldn’t minimize the importance of these findings.

“That it’s small doesn’t diminish its value,” he said. “The next step forward might be to try to associate the markers more specifically with COVID. The more precise we can be, the more convincing the story will become.”

The study was funded by the National Institutes of Health. Dr. Hellmuth received grant support from the National Institutes of Health/National Institute of Mental Health supporting this work and personal fees for medical-legal consultation outside of the submitted work. Dr. Schaffner disclosed no relevant financial relationships.

The Centers for Disease Control and Prevention has recommended that all adults aged 19-59 years receive a vaccination for hepatitis B.

It also added that adults aged 60 years or older without known risk factors for hepatitis B may get vaccinated.

The agency earlier recommended the vaccination for all infants and children under the age of 19 years and for adults aged 60 years or older with known risk factors.

The CDC said it wants to expand vaccinations because, after decades of progress, the number of new hepatitis B infections is increasing among adults. Acute hepatitis B infections among adults lead to chronic hepatitis B disease in an estimated 2%-6% of cases, and can result in cirrhosis, liver cancer, and death.

Among adults aged 40-49 years, the rate of cases increased from 1.9 per 100,000 people in 2011 to 2.7 per 100,000 in 2019. Among adults aged 50-59 years, the rate increased during this period from 1.1 to 1.6 per 100,000.

Most adults aren’t vaccinated. Among adults aged 19 years or older, only 30.0% reported that they’d received at least the three recommended doses of the vaccine. The rate was 40.3% for adults aged 19-49 years, and 19.1% for adults aged 50 years or older.

Hepatitis B infection rates are particularly elevated among African Americans.

Even among adults with chronic liver disease, the vaccination rate is only 33.0%. And, among travelers to countries where the virus has been endemic since 1995, only 38.9% were vaccinated.

In a 2018 survey of internal medicine and family physicians, 68% said their patients had not told them about risk factors, making it difficult to assess whether the patients needed the vaccine according to the recommendations at the time. These risk factors include injection drug use, incarceration, and multiple sex partners, experiences the patients may not have been willing to discuss.

CDC researchers calculated that universal adult hepatitis B vaccination would cost $153,000 for every quality-adjusted life-year (QALY) gained. For adults aged 19-59 years, a QALY would cost $117,000 because infections are more prevalent in that age group.

The CDC specified that it intends its new guidelines to prompt physicians to offer the vaccine to adults aged 60 years or older rather than wait for them to request it.

The Food and Drug Administration has approved both three-dose and two-dose hepatitis B vaccines, with evidence showing similar seroprotection and adverse events.

People who have already completed their vaccination or have a history of hepatitis B infection should only receive additional vaccinations in specific cases, as detailed in the CDC’s 2018 recommendations.

The new heart failure (HF) guidelines released by three North American societies had a lot of catching up to do given the significant, even paradigm-shifting, additions to available treatment options in the last few years.

The landscape now includes both new and repurposed drug therapies that benefit almost without regard to ejection fraction (EF), and evidence-based urgency to engage patients early on with at least four core medication classes, so-called quadruple therapy.

Catherine Hackett/MDedge News

The guideline document offers a roadmap for navigating those key issues and many others and uses some creative tactics. They include the introduction of generalist-friendly labels for the traditional but obscurely named four stages of HF severity that, it is hoped, will have wider reach and expand the use of effective therapies.

It introduces additional disease-staging terminology that characterizes the syndrome as a continuum:  

• “At risk for HF” for stage A, applied to asymptomatic patients with risk factors such as diabetes or hypertension but no known cardiac changes.
• “Pre-HF” for stage B, which adds cardiac structural changes or elevated natriuretic peptides, still in the absence of symptoms.
• “Symptomatic HF” for stage C, that is, structural disease with current or previous symptoms.
• “Advanced HF” for stage D, characterized by severe debilitating symptoms or repeated hospitalizations even with guideline-directed medical therapy (GDMT).

The new terms should be “easier for primary care physicians as well as nonspecialists” to remember and use effectively “and easier to translate to the patients,” compared with the solely alphabetical staging labels appearing in the guidelines for more than 15 years, Biykem Bozkurt, MD, PhD, Baylor College of Medicine, Houston, said in an interview.

An emphasis on “at risk for HF” and “pre-HF” in the new document may help efforts to expand primary prevention of HF and management of preclinical HF. The guideline, Dr. Bozkurt said, includes specific treatment recommendations for those early stages.

The document also updates and sometimes introduces “recommendations for advanced heart failure, acute heart failure, and comorbidities – specifically for atrial fibrillation, iron deficiency, sleep apnea, coronary artery disease, and valvular heart disease,” Dr. Bozkurt observed, as well as for cardiomyopathy and HF related to pregnancy and cancer chemotherapy. “So, it’s a very comprehensive guideline.”

Dr. Bozkurt is vice chair of the guideline writing committee and helped introduce the guideline at the annual scientific sessions of the American College of Cardiology. The document, developed by the ACC, the American Heart Association, and the Heart Failure Society of America, was published April 1, 2022, in the societies’ flagship journals, Journal of the American College of Cardiology, Circulation, and the Journal of Cardiac Failure, respectively. It replaces the 2013 guideline from the ACC and AHA and the ACC/AHA/HFSA–focused update from 2017.

“We really need to treat early, and then we need to treat appropriately,” Douglas L. Mann, MD, Washington University in St. Louis, said in an interview. Dr. Mann, who was not involved in development of the new guideline, said he is “enthusiastic” about the new staging terminology.

“I think it makes it easier to convey the message that these people do need medicines, will benefit from medicines, and in some cases heart failure can be preventable,” he said. “I’m in favor of anything that simplifies it and makes it more readily interpretable by busy doctors who aren’t specialists.”

With the new staging terminology and in other ways, the guideline seems to appreciate cardiomyopathy as a journey from preclinical to advanced symptomatic stages – the preclinical “at-risk” stage tightening focus on primary prevention – and updated thinking on classification of HF by EF.

For example, there is new consideration of “HF with improved ejection fraction” (HFimpEF), which suggests the patient may be evolving from HF with reduced EF (HFrEF) to HF with EF that is preserved or mildly reduced, or vice versa.

With HFimpEF, which identifies patients previously with an EF of 40% or lower that improves to beyond 40% at follow-up testing, patients should continue on the medications they had been previously taking for HFrEF, Dr. Bozkurt said.

Patients at risk for HF, in stage A by the older terminology, are characterized by one or more significant HF risk factors, such as hypertension, diabetes, or coronary disease, as they have been in prior guidelines. But the new document, Dr. Bozkurt observed, adds genetic cardiomyopathies and exposure to cardiotoxic agents to the list.

Perhaps surprisingly, the guideline also includes elevated natriuretic peptides as an indicator of “at risk for HF,” with implications for screening. The evidence suggests that, “for patients who are at risk for heart failure, natriuretic peptide-based screening, followed by team-based care, can prevent development of left ventricular dysfunction in heart failure,” Dr. Bozkurt said.

Persons at risk for HF realistically encompass a huge swath of the population given the world prevalence of high blood pressure, obesity, and diabetes. Management of stage A, therefore, focuses on established tenets of primary cardiovascular prevention, such as weight and BP control, exercise, and healthy dietary choices.

They may well be eligible for treatment with sodium-glucose transporter 2 (SGLT2) inhibitors, which have been “game changers,” Dr. Mann said. “Now you can give them to diabetics and it’s going to prevent heart failure and [cardiovascular] events. We didn’t have a drug like that before, so I think that places a lot of emphasis on aggressive treatment of diabetes.”

For patients with symptomatic HF, the document touts multidisciplinary care and early initiation of drugs from each of four drug classes. Such quadruple therapy includes an SGLT2 inhibitor along with a beta-blocker, a mineralocorticoid receptor antagonist (MRA), and a renin-angiotensin system (RAS) inhibitor: the “core foundational therapies” for patients with HFrEF, Dr. Bozkurt observed.

Of note, she said, the angiotensin receptor–neprilysin inhibitor sacubitril/valsartan (Entresto, Novartis) is the preferred RAS inhibitor. But “if the ARNI cannot be used, then use ACE inhibitors.” If the patient is intolerant of ACE inhibitors because of cough or angioedema, then the choice should be an angiotensin-receptor blocker.

“We have very effective therapies offering survival and morbidity benefits as well as improvements in quality of life and reverse remodeling,” Dr. Bozkurt observed. “The most important message is that optimization of therapies, including all of these medication classes, saves lives.”

The guideline also includes, for the first time, a series of “value statements” on cost-effectiveness of different therapies that assign a “high-value” rating to MRAs, hydralazine, and isosorbide dinitrate in otherwise optimally treated self-identified African Americans, and device therapy in appropriately selected patients. The statements hold SGLT2 inhibitors in chronic symptomatic HF and cardiac transplantation in advanced GDMT-resistant HF to be of “intermediate” value.

The value statements, Dr. Bozkurt noted, “are included throughout the document when there is evidence; when there is a high-quality cost-effectiveness study published.”

Dr. Bozkurt disclosed receiving honoraria or consulting fees from Amgen, AstraZeneca, Baxter International, Bristol-Myers Squibb, Sanofi-Aventis, scPharmaceuticals, and Vifor Pharma; serving on a data safety monitoring board for LivaNova USA; and holding other relationships with Abbott Laboratories and Relypsa.

The new heart failure (HF) guidelines released by three North American societies had a lot of catching up to do given the significant, even paradigm-shifting, additions to available treatment options in the last few years.

The landscape now includes both new and repurposed drug therapies that benefit almost without regard to ejection fraction (EF), and evidence-based urgency to engage patients early on with at least four core medication classes, so-called quadruple therapy.

The guideline document offers a roadmap for navigating those key issues and many others and uses some creative tactics. They include the introduction of generalist-friendly labels for the traditional but obscurely named four stages of HF severity that, it is hoped, will have wider reach and expand the use of effective therapies.

It introduces additional disease-staging terminology that characterizes the syndrome as a continuum:  

• “At risk for HF” for stage A, applied to asymptomatic patients with risk factors such as diabetes or hypertension but no known cardiac changes.
• “Pre-HF” for stage B, which adds cardiac structural changes or elevated natriuretic peptides, still in the absence of symptoms.
• “Symptomatic HF” for stage C, that is, structural disease with current or previous symptoms.
• “Advanced HF” for stage D, characterized by severe debilitating symptoms or repeated hospitalizations even with guideline-directed medical therapy (GDMT).

The new terms should be “easier for primary care physicians as well as nonspecialists” to remember and use effectively “and easier to translate to the patients,” compared with the solely alphabetical staging labels appearing in the guidelines for more than 15 years, Biykem Bozkurt, MD, PhD, Baylor College of Medicine, Houston, said in an interview.

An emphasis on “at risk for HF” and “pre-HF” in the new document may help efforts to expand primary prevention of HF and management of preclinical HF. The guideline, Dr. Bozkurt said, includes specific treatment recommendations for those early stages.

The document also updates and sometimes introduces “recommendations for advanced heart failure, acute heart failure, and comorbidities – specifically for atrial fibrillation, iron deficiency, sleep apnea, coronary artery disease, and valvular heart disease,” Dr. Bozkurt observed, as well as for cardiomyopathy and HF related to pregnancy and cancer chemotherapy. “So, it’s a very comprehensive guideline.”

Dr. Bozkurt is vice chair of the guideline writing committee and helped introduce the guideline at the annual scientific sessions of the American College of Cardiology. The document, developed by the ACC, the American Heart Association, and the Heart Failure Society of America, was published April 1, 2022, in the societies’ flagship journals, Journal of the American College of Cardiology, Circulation, and the Journal of Cardiac Failure, respectively. It replaces the 2013 guideline from the ACC and AHA and the ACC/AHA/HFSA–focused update from 2017.

“We really need to treat early, and then we need to treat appropriately,” Douglas L. Mann, MD, Washington University in St. Louis, said in an interview. Dr. Mann, who was not involved in development of the new guideline, said he is “enthusiastic” about the new staging terminology.

“I think it makes it easier to convey the message that these people do need medicines, will benefit from medicines, and in some cases heart failure can be preventable,” he said. “I’m in favor of anything that simplifies it and makes it more readily interpretable by busy doctors who aren’t specialists.”

People who received personalized nutrition education in a series of sessions at their regular grocery store significantly improved adherence to a healthy diet, in a new “first-of-its-kind” study in which scientific researchers partnered with a large supermarket company.

In the SuperWIN study, participants were given individualized advice from supermarket-based dietitians using data on their own buying habits recorded on their supermarket loyalty cards. This was associated with an increased adherence to the DASH (Dietary Approaches to Stop Hypertension) diet, which emphasizes vegetables, fruits and whole grains while limiting foods that are high in saturated fat, sugar, and sodium and has been shown to lower blood pressure and LDL cholesterol.

One group of patients also received additional education about healthy eating and meal planning through online technologies, and this group showed even better adherence to the DASH diet.

The study was presented at the annual scientific sessions of the American College of Cardiology by Dylan Steen, MD, adjunct associate professor of medicine at the University of Cincinnati.

“The SuperWIN study provides evidence for the benefit of delivering healthy-eating interventions at modern supermarkets and retail-based clinics,” Dr. Steen said. “It demonstrates the efficacy of dietary interventions harnessing the physical environment of the supermarket, the retail-based dietitians working within the store, and the purchasing data captured on the store’s loyalty cards.”

The study was conducted in partnership with Kroger, the largest supermarket chain in the United States, which also operates a large chain of pharmacies and health clinics.

Dr. Steen said the study was addressing one of the biggest public health problems – unhealthy eating – with an innovative approach. “We need to think about how we can extend the reach of modern health care systems into communities and better deliver services right where people are; meet them where they live,” he said at an ACC press conference.

Commenting on the study at the press conference, Eileen Handberg, PhD, professor of medicine at University of Florida, Gainesville, and immediate past chair of the ACC Cardiovascular Care Team Council, said: “I am amazingly excited about this. There is so much potential here. We have never really taken advantage of the current explosion in retail-based health care before.”

Dr. Handberg suggested the study had major implications for the primary prevention of cardiovascular disease. “Little kids go shopping with their parents, so you have the ability here to change behavior from children on up if you can change the dynamic of the choices they make in the grocery store.”

In his presentation, Dr. Steen noted that, despite many longstanding guidelines on healthy eating, about 75% of Americans still have a poor-quality diet. This trial was conducted to see if a new approach could improve that situation. “If we change the environment in which we deliver dietary education, we can make a difference.”

The SuperWIN trial was conducted in 13 Kroger stores in Ohio and Kentucky. The study enrolled 267 people with at least one cardiovascular risk factor from a primary care network who regularly shopped at one of the study stores. All participants also had to be willing to follow the DASH diet, which was taught at each educational session in the trial.

All participants received one “enhanced” medical nutrition therapy that was guided by the individual’s own dietary intake analytics.

They were then randomly assigned to one of three arms. The control group received no further education. The strategy 1 group received six additional teaching sessions in the supermarket aisles over a 3-month period. Each session was guided by updated individualized purchasing data provided to the dietitian and the participant. 

The strategy 2 group received the same six additional teaching sessions as strategy 1, but they also had some additional teaching on healthy eating and meal planning from a variety of online shopping tools, and nutrition and health care apps.  

“The supermarket analytics were automatically collected so the dietitians could tell what each person liked to eat, how much of each product they were buying and how much they were spending,” Dr. Steen explained.

COVID hit halfway through the trial, and 20 participants were withdrawn for their own safety as they could no longer visit the stores, but the trial continued with the rest of the participants with enhanced safety precautions. The overall analysis cohort was 247 participants.

The average age of the participants was mid-50s, around 70% were female, and most did not have a history of cardiovascular disease.

Eating habits were assessed by three 24-hour dietary recalls assessed at the start of the study and at 3 and 6 months. The DASH score, which is a measure of adherence to the DASH diet, was calculated from this information. The score can range from 0 to 90, with an increased score showing increased adherence.

In one analysis, the researchers compared the DASH scores from the two intervention groups together with the control group, and in a second analysis they compared the scores in the strategy 2 group with those in the strategy 1 group.

Before the pandemic there was “near 100%” attendance for the six visits over the 3-month study period, which Dr. Steen said he thought was “remarkable.” During the pandemic, attendance came down to around 80%.

Results showed that the DASH score increased in all three groups at 3 months, with stepwise increases corresponding to the intensity of the intervention. DASH scores increased by 5.8 points in the control group, by 8.6 points in the strategy 1 group, and by 12.4 points in the strategy 2 group.

DASH scores significantly differed between the two intervention groups and the control group (P = .02). “This shows that purchasing data–guided in-store tours do increase the efficacy of dietary education,” Dr. Steen said.

The difference in scores between the strategy 1 and strategy 2 groups was also significant (P = .01). “This shows online enhancements increase adherence to the DASH diet even further,” Dr. Steen commented

By 6 months, the scores had dropped off a little but were still increased from baseline: by 4.4 points in the control group, 6.6 points in the strategy 1 group, and 8.4 points in the strategy 2 group. “There was again a stepwise increase as the intervention intensified, but there was no longer a significant difference between the interventions and control,” Dr. Steen noted.

Secondary endpoints included blood pressure and body mass index. Systolic blood pressure decreased slightly in all three groups: by 2.8 mm Hg in the control group, 6.6 mm Hg in the strategy 1 group, and 5.7 mm Hg in the strategy 2 group. Body mass index was reduced by 0.2, 0.4 and 0.8, respectively, but the between-group differences were not significant.

Dr. Steen said this is the first study of its kind to date in which scientific researchers collaborated with a large supermarket chain. He explained they also involved a primary care network so that health care utilization information will be available.

“We can the integrate retail-based health care information with traditional health care information. And we can start to look at downstream health care utilization and cost outcomes as well, which will be important as we start to think how to evolve the health care system,” he commented. “The hope is that we can get more scientists working with more retailers to really drive the evidence to shape the evolution of our health care system.”

Challenges ahead

Dr. Handberg pointed out there would be challenges in reaching the underserved population who do not shop at the major supermarkets. “We need to figure out how to get partnerships across the whole spectrum of grocery stores.”

She also noted that 3 months (the duration of the study intervention) was not much time to change the eating habits of a family. “Interventions may have to be a bit more intensive to get the change in blood pressure and weight that we would want to see.”

Dr Handberg hoped the major grocery store companies will see the opportunities in this approach. “Changing behavior is very complicated, and the key will be how to make people stick with the changes. But grocery stores are smart. They have got us going to their pharmacies, so getting us to see a dietitian is not that much of a stretch.”

Moderator of the ACC late-breaker session at which the study was presented, Pamela Morris, MD, from the Medical University of South Carolina, Charleston, who is also ACC annual scientific session chair, asked whether the approach could be sustained.

“I am thinking back to the barber shop study of blood pressure treatment and to my knowledge those PharmDs are no longer in those barbershops, taking blood pressures, counseling patients, and prescribing antihypertensives. So is Kroger maintaining a long-term commitment to providing this education, or how can this be financed over the long term?” she asked.

Dr. Steen replied that he believed sustainability to be one of the key strengths of this model. “Retail-based health care is exploding in the U.S. The number of retail outlets offering a comprehensive list of services is going up all the time. These programs exist regardless of whether this trial was conducted or not.”

But Dr. Steen stressed that having an evidence base will be critically important.

“Validation is an enormous part of this evolution in retail-based health care – not only to figure out what works but also to engage payors and others in the process of supporting these interventions. I think the sustainability is there – it is sort of baked into the model – but research will be a huge part of cementing this in and helping us to understand what we should do.”

The study was funded by Kroger. Dr. Steen is a consultant for Sanofi and CEO and cofounder of High Enroll.

Dr Handberg hoped the major grocery store companies will see the opportunities in this approach. “Changing behavior is very complicated, and the key will be how to make people stick with the changes. But grocery stores are smart. They have got us going to their pharmacies, so getting us to see a dietitian is not that much of a stretch.”

Moderator of the ACC late-breaker session at which the study was presented, Pamela Morris, MD, from the Medical University of South Carolina, Charleston, who is also ACC annual scientific session chair, asked whether the approach could be sustained.

“I am thinking back to the barber shop study of blood pressure treatment and to my knowledge those PharmDs are no longer in those barbershops, taking blood pressures, counseling patients, and prescribing antihypertensives. So is Kroger maintaining a long-term commitment to providing this education, or how can this be financed over the long term?” she asked.

Dr. Steen replied that he believed sustainability to be one of the key strengths of this model. “Retail-based health care is exploding in the U.S. The number of retail outlets offering a comprehensive list of services is going up all the time. These programs exist regardless of whether this trial was conducted or not.”

But Dr. Steen stressed that having an evidence base will be critically important.

“Validation is an enormous part of this evolution in retail-based health care – not only to figure out what works but also to engage payors and others in the process of supporting these interventions. I think the sustainability is there – it is sort of baked into the model – but research will be a huge part of cementing this in and helping us to understand what we should do.”

People who received personalized nutrition education in a series of sessions at their regular grocery store significantly improved adherence to a healthy diet, in a new “first-of-its-kind” study in which scientific researchers partnered with a large supermarket company.

In the SuperWIN study, participants were given individualized advice from supermarket-based dietitians using data on their own buying habits recorded on their supermarket loyalty cards. This was associated with an increased adherence to the DASH (Dietary Approaches to Stop Hypertension) diet, which emphasizes vegetables, fruits and whole grains while limiting foods that are high in saturated fat, sugar, and sodium and has been shown to lower blood pressure and LDL cholesterol.

One group of patients also received additional education about healthy eating and meal planning through online technologies, and this group showed even better adherence to the DASH diet.

The study was presented at the annual scientific sessions of the American College of Cardiology by Dylan Steen, MD, adjunct associate professor of medicine at the University of Cincinnati.

“The SuperWIN study provides evidence for the benefit of delivering healthy-eating interventions at modern supermarkets and retail-based clinics,” Dr. Steen said. “It demonstrates the efficacy of dietary interventions harnessing the physical environment of the supermarket, the retail-based dietitians working within the store, and the purchasing data captured on the store’s loyalty cards.”

The study was conducted in partnership with Kroger, the largest supermarket chain in the United States, which also operates a large chain of pharmacies and health clinics.

Dr. Steen said the study was addressing one of the biggest public health problems – unhealthy eating – with an innovative approach. “We need to think about how we can extend the reach of modern health care systems into communities and better deliver services right where people are; meet them where they live,” he said at an ACC press conference.

Commenting on the study at the press conference, Eileen Handberg, PhD, professor of medicine at University of Florida, Gainesville, and immediate past chair of the ACC Cardiovascular Care Team Council, said: “I am amazingly excited about this. There is so much potential here. We have never really taken advantage of the current explosion in retail-based health care before.”

Dr. Handberg suggested the study had major implications for the primary prevention of cardiovascular disease. “Little kids go shopping with their parents, so you have the ability here to change behavior from children on up if you can change the dynamic of the choices they make in the grocery store.”

In his presentation, Dr. Steen noted that, despite many longstanding guidelines on healthy eating, about 75% of Americans still have a poor-quality diet. This trial was conducted to see if a new approach could improve that situation. “If we change the environment in which we deliver dietary education, we can make a difference.”

The SuperWIN trial was conducted in 13 Kroger stores in Ohio and Kentucky. The study enrolled 267 people with at least one cardiovascular risk factor from a primary care network who regularly shopped at one of the study stores. All participants also had to be willing to follow the DASH diet, which was taught at each educational session in the trial.

All participants received one “enhanced” medical nutrition therapy that was guided by the individual’s own dietary intake analytics.

They were then randomly assigned to one of three arms. The control group received no further education. The strategy 1 group received six additional teaching sessions in the supermarket aisles over a 3-month period. Each session was guided by updated individualized purchasing data provided to the dietitian and the participant. 

The strategy 2 group received the same six additional teaching sessions as strategy 1, but they also had some additional teaching on healthy eating and meal planning from a variety of online shopping tools, and nutrition and health care apps.  

“The supermarket analytics were automatically collected so the dietitians could tell what each person liked to eat, how much of each product they were buying and how much they were spending,” Dr. Steen explained.

COVID hit halfway through the trial, and 20 participants were withdrawn for their own safety as they could no longer visit the stores, but the trial continued with the rest of the participants with enhanced safety precautions. The overall analysis cohort was 247 participants.

The average age of the participants was mid-50s, around 70% were female, and most did not have a history of cardiovascular disease.

Eating habits were assessed by three 24-hour dietary recalls assessed at the start of the study and at 3 and 6 months. The DASH score, which is a measure of adherence to the DASH diet, was calculated from this information. The score can range from 0 to 90, with an increased score showing increased adherence.

In one analysis, the researchers compared the DASH scores from the two intervention groups together with the control group, and in a second analysis they compared the scores in the strategy 2 group with those in the strategy 1 group.

Before the pandemic there was “near 100%” attendance for the six visits over the 3-month study period, which Dr. Steen said he thought was “remarkable.” During the pandemic, attendance came down to around 80%.

Results showed that the DASH score increased in all three groups at 3 months, with stepwise increases corresponding to the intensity of the intervention. DASH scores increased by 5.8 points in the control group, by 8.6 points in the strategy 1 group, and by 12.4 points in the strategy 2 group.

DASH scores significantly differed between the two intervention groups and the control group (P = .02). “This shows that purchasing data–guided in-store tours do increase the efficacy of dietary education,” Dr. Steen said.

The difference in scores between the strategy 1 and strategy 2 groups was also significant (P = .01). “This shows online enhancements increase adherence to the DASH diet even further,” Dr. Steen commented

By 6 months, the scores had dropped off a little but were still increased from baseline: by 4.4 points in the control group, 6.6 points in the strategy 1 group, and 8.4 points in the strategy 2 group. “There was again a stepwise increase as the intervention intensified, but there was no longer a significant difference between the interventions and control,” Dr. Steen noted.

Secondary endpoints included blood pressure and body mass index. Systolic blood pressure decreased slightly in all three groups: by 2.8 mm Hg in the control group, 6.6 mm Hg in the strategy 1 group, and 5.7 mm Hg in the strategy 2 group. Body mass index was reduced by 0.2, 0.4 and 0.8, respectively, but the between-group differences were not significant.

Dr. Steen said this is the first study of its kind to date in which scientific researchers collaborated with a large supermarket chain. He explained they also involved a primary care network so that health care utilization information will be available.

“We can the integrate retail-based health care information with traditional health care information. And we can start to look at downstream health care utilization and cost outcomes as well, which will be important as we start to think how to evolve the health care system,” he commented. “The hope is that we can get more scientists working with more retailers to really drive the evidence to shape the evolution of our health care system.”

Challenges ahead

Dr. Handberg pointed out there would be challenges in reaching the underserved population who do not shop at the major supermarkets. “We need to figure out how to get partnerships across the whole spectrum of grocery stores.”

She also noted that 3 months (the duration of the study intervention) was not much time to change the eating habits of a family. “Interventions may have to be a bit more intensive to get the change in blood pressure and weight that we would want to see.”

WASHINGTON – Results from new analyses further fleshed out the potent effect by the investigational SGLT1&2 inhibitor sotagliflozin on major cardiovascular adverse events in patients with type 2 diabetes, chronic kidney disease, and at high risk for cardiovascular disease in the SCORED trial that randomized more than 10,000 patients.

In prespecified, secondary analyses of the SCORED results, treatment with sotagliflozin during a median of 16 months was linked to a significant 21% risk reduction relative to placebo for the combined incidence of total major adverse cardiovascular events (MACE), which included cardiovascular death, first and recurrent episodes of nonfatal MI, and nonfatal stroke among the 5,144 randomized patients who entered the trial with a history of cardiovascular disease (CVD), Deepak L. Bhatt, MD, said at the annual scientific sessions of the American College of Cardiology.

Mitchel L. Zoler/MDedge News

Among the 5,440 patients in the study who did not have a history of CVD (although they did have at least one major risk factor or at least two minor risk factors), treatment with sotagliflozin was linked to a significant 26% relative risk reduction in total MACE events.

Part of these overall MACE benefits resulted from similar improvements from sotagliflozin treatment on the individual outcomes of total nonfatal MI and total nonfatal strokes. Treatment with sotagliflozin cut these MIs by a significant 31% in patients with a history of CVD relative to patients who received placebo, and by a relative 34% in those without a CVD event in their history, a difference compared with placebo that fell short of significance, said Dr. Bhatt, professor of medicine at Harvard Medical School and executive director of interventional cardiovascular programs at Brigham and Women’s Health, both in Boston.

Treatment with sotagliflozin also cut total nonfatal strokes by 31% relative to placebo in patients with a history of CVD, and by a relative 38% in those without a CVD history. Both differences fell short of significance.
 

An early MACE benefit and a stroke benefit

“This stroke benefit has not been clearly seen” with any agent from the closely related sodium-glucose cotransport-2 (SGLT2) inhibitor class, and “the MACE benefit appeared very early,” within 3 months from the start of sotagliflozin treatment, “which may be because of the SGLT1 inhibition,” Dr. Bhatt said during his report.

The SGLT1 receptor is the primary mechanism cells in the gut use to absorb glucose and galactose in the human gastrointestinal tract, Dr. Bhatt explained, while the SGLT2 receptor appears on kidney cells and is the major player in the reabsorption of filtered glucose. The SGLT2 inhibitor class includes the agents canagliflozin (Invokana), dapagliflozin (Farxiga), and empagliflozin (Jardiance), while sotagliflozin inhibits both SGLT1 and SGLT2.

Main results from SCORED appeared in a report first released in late 2020, and showed that for the study’s primary endpoint treatment with sotagliflozin linked with a significant 26% relative risk reduction for the composite of cardiovascular deaths, hospitalizations for heart failure, and urgent visits for heart failure (N Engl J Med. 2021 Jan 14;384[2]:129-39). Patient follow-up in SCORED was not as long as originally planned when the study stopped early due to a loss of funding from a sponsor that was triggered by the COVID-19 pandemic.

MACE results ‘heterogeneous’ from SGLT2 inhibitors

Sotagliflozin and agents from the SGLT2 inhibitor class “have been consistent” in their benefits for reducing cardiovascular death and hospitalization for heart failure, but for MACE, the results from the SGLT2 inhibitors “have been more heterogeneous,” and the effect of sotagliflozin on MACE “were different in SCORED,” commented Michelle L. O’Donoghue, MD, MPH, a cardiologist at Brigham and Women’s Hospital in Boston who was not involved with this work.

Mitchel L. Zoler/MDedge News

“The results suggest a benefit [from sotagliflozin] on atherosclerotic events, which could be a potential advantage” compared with the SGLT2 inhibitors, “but the heterogeneity of this effect” among these agents means that more confirmatory data are needed for sotagliflozin, Dr. O’Donoghue said in an interview.

“There is a lot of enthusiasm for the concept” of combined inhibition of the SGLT1 and 2 receptors, and if more evidence for unique benefits of this effect accumulate “it may lead to increased enthusiasm for sotagliflozin,” she said. “A lot will also depend on pricing decisions” for sotagliflozin, if it receives U.S. marketing approval from the Food and Drug Administration. Decisions about which agent from the SGLT2 inhibitor class to prescribe “are often being made based on price right now,” Dr. O’Donoghue said.

Lexicon Pharmaceuticals, the company developing sotagliflozin, has announced plans to resubmit its new drug application for sotagliflozin to the FDA later in 2022, with the agency’s approval decision likely occurring late in 2022 or sometime during 2023. In February, the company withdrew its December 2021 application to correct a “technical issue” it had found.

An additional analysis reported by Dr. Bhatt used combined data from SCORED as well as several additional randomized trials of sotagliflozin involving a total of more than 20,000 patients that showed a significant 21% reduction in the incidence of MACE compared with placebo.

During his talk, Dr. Bhatt said that sotagliflozin was potentially superior to the agents that inhibit only SGLT2. In an interview, he based this tentative assessment on at least four attributes of sotagliflozin that have emerged from trial results:

• The drug’s ability to significantly reduce MACE and to have this effect apparent within a few months of treatment onset;
• The significantly reduced rate of stroke with sotagliflozin (when patients are not subdivided into those with or without a history of CVD) that has not yet been seen with any SGLT2 inhibitor;
• The ability of sotagliflozin to reduce hemoglobin A1c levels in patients with type 2 diabetes even when their estimated glomerular filtration rate is less than 30 mL/min per 1.73 m², an effect not seen with SGLT2 inhibitors and possibly explained by sotagliflozin having an effect on gut absorption of glucose in addition to its SGLT2 inhibitory effect in the kidney;
• And the proven ability of sotagliflozin to be safe and effective when initiated in patients hospitalized for heart failure, a property that so far has only also been shown for the SGLT2 inhibitor empagliflozin in the EMPULSE trial (Nature Med. 2022 Mar;28: 568-74).

SCORED was sponsored by Sanofi and Lexicon Pharmaceuticals, the companies originally developing sotagliflozin, although with the withdrawal of Sanofi’s support, further development is now sponsored entirely by Lexicon. Dr. Bhatt received research funding from Sanofi and Lexicon that was paid to Brigham and Women’s Health, and he has been an advisor to numerous companies. Dr. O’Donoghue has been a consultant to Amgen, Janssen, and Novartis, and has received research funding from Amgen, AZ MedImmune, Intarcia, Janssen, Merck, and Novartis.

Pregnant women with even mild hypertension should receive blood pressure–lowering medications to reduce the likelihood of adverse outcomes for the mother and the child, according to a large, open-label, randomized trial.

“Treating to the blood pressure goal in this study reduced the risk of adverse events associated with pregnancy but did not impair fetal growth,” Alan T. Tita, MD, PhD, associate dean for Global and Women’s Health, University of Alabama, Birmingham, reported at the annual scientific sessions of the American College of Cardiology.

The question of whether to treat chronic hypertension during pregnancy has been “an international controversy for decades,” said Dr. Tita, who led the investigator-initiated Chronic Hypertension and Pregnancy (CHAP) trial.

For the composite primary outcome of severe preeclampsia, medically indicated preterm birth at less than 35 weeks of gestation, placental abruption, or fetal/neonatal death, the treatment of hypertension versus no treatment showed a relative risk reduction of 18% (30.2% vs. 37%, (hazard ratio, 0.82; P < .001).
 

Small for gestational age is primary safety endpoint

An increase in preeclampsia risk in women whose fetus was small for gestational age (SGA), a theoretical consequence of reductions in arterial pressure, was not seen. The rate of SGA, defined as below the 10^th percentile, was slightly higher in the treatment group (11.2% vs. 10.4%), but the difference did not approach significance (P = 0.76).

By answering this long-pending question, the CHAP data are “practice changing,” declared an ACC-invited commentator, Athena Poppas, MD, chief of cardiology and director of the Lifespan Cardiovascular Institute, Providence, R.I. She agreed that the need for treatment of mild chronic hypertension has been a dilemma for clinicians that is now acceptably resolved.

In this trial, 2,408 pregnant women with chronic mild hypertension defined as a blood pressure of 160/90 mm Hg were randomized to treatment with a goal blood pressure of less than 140/90 mm Hg or no treatment unless the blood pressure rose to at least 160/105. All women had singleton pregnancies. Enrollment before 23 weeks of gestation was required. Severe hypertension (at least 160/105 mm Hg) was an exclusion criterion, as were several comorbidities, such as kidney disease.
 

Combination therapy accepted for <140/90 mm Hg goal

The beta-blocker labetalol or the calcium channel blocker nifedipine as single agents were the preferred antihypertensive medications in the protocol, but other medications were permitted. To reach the blood pressure goal, the single-agent therapy was titrated to the maximum dose before starting a second agent.

After randomization the systolic and diastolic blood pressures fell in both groups, but they fell more and remained consistently lower in the active treatment group, particularly during the first 20 weeks after randomization, according to graphs displayed by Dr. Tita. Over the course of the study, the mean diastolic blood pressures were 129.5 and 132.6 mm Hg in the active treatment and control groups, respectively, while the systolic pressures were 79.1 vs. 81.5 mm Hg.

When the components of the primary outcome were evaluated separately, the greatest advantage of treatment was the reduction in the rate of severe eclampsia (23.3% vs. 29.1%; HR, 0.80: 95% confidence interval, 0.70-0.92) and preterm birth (12.2% vs. 16.7%; HR, 0.73: 95% CI, 0.60-0.89).

Across a large array of subgroups, including those with or without diabetes and those treated before or after 14 weeks of gestation, there was a consistent advantage for treatment, even if not statistically different. It is notable that 48% of patients were Black and 35% had a body mass index of at least 40. The active treatment was favored across all groups stratified by these characteristics.

Although the incidences of placental abruption (1.7% on treatment vs. 1.9% without) and fetal or neonatal death (3.5% vs. 4.3%) were lower in the active treatment group, they were uncommon events in both arms of the study. The differences did not reach statistical significance.
 

Maternal morbidity rates lower on treatment

Severe SGA, which was defined as below the 5^th percentile, was also numerically but not significantly higher in the control arm than in the group receiving treatment (5.1% vs. 5.5%), but the incidence of composite adverse maternal events was numerically lower (2.1% vs. 2.8%). The incidences of all components of maternal morbidity, such as maternal death (0.1% vs. 0.2%) pulmonary edema (0.4% vs. 0.9%), heart failure (0.1% vs. 0.1%), and acute kidney injury (0.8% vs. 1.2%), were either lower or the same on active treatment versus no treatment.

According to Dr. Tita, who called CHAP one of the largest and most diverse studies to address the value of treating mild hypertension in pregnancy, the American College of Obstetricians and Gynecologists (ACOG) is evaluating these data for changing their current guidelines for managing hypertension during pregnancy.

“The rate of chronic hypertension during pregnancy has been rising in the United States due to the increase in the average age of pregnant women and the rising rates of obesity,” Dr. Tita commented.

“We definitely needed these data,” said Mary Norine Walsh, MD, medical director, Ascension Saint Vincent Cardiovascular Research Institute, Indianapolis. Not only has the value of treating mild hypertension been unresolved, but Dr. Walsh pointed out that the rates of maternal mortality in the United States are rising and now generally exceed those of many other developed countries.

There are several features in the design of this trial that make the results even more salient to clinical practice, according to Dr. Walsh. This includes the fact that about half of patients enrolled were on Medicaid. As a result, the study confirmed benefit in what Dr. Walsh characterized as a “vulnerable” population.

“We will be busy now to make sure that our [pregnant] patients are achieving these target blood pressures,” Dr. Walsh said. She indicated that CHAP validates the treatment target of 140/90 mm Hg as a standard of care.

The results were published in the New England Journal of Medicine simultaneously with its ACC presentation.

The trial was funded by the National Heart, Lung, and Blood Institute. Dr. Tita reports research grants from Pfizer. Dr. Walsh reports a financial relationship with EBR Systems. Dr. Poppas reports no potential conflicts of interest.

Pregnant women with even mild hypertension should receive blood pressure–lowering medications to reduce the likelihood of adverse outcomes for the mother and the child, according to a large, open-label, randomized trial.

“Treating to the blood pressure goal in this study reduced the risk of adverse events associated with pregnancy but did not impair fetal growth,” Alan T. Tita, MD, PhD, associate dean for Global and Women’s Health, University of Alabama, Birmingham, reported at the annual scientific sessions of the American College of Cardiology.

The question of whether to treat chronic hypertension during pregnancy has been “an international controversy for decades,” said Dr. Tita, who led the investigator-initiated Chronic Hypertension and Pregnancy (CHAP) trial.

For the composite primary outcome of severe preeclampsia, medically indicated preterm birth at less than 35 weeks of gestation, placental abruption, or fetal/neonatal death, the treatment of hypertension versus no treatment showed a relative risk reduction of 18% (30.2% vs. 37%, (hazard ratio, 0.82; P < .001).
 

Small for gestational age is primary safety endpoint

An increase in preeclampsia risk in women whose fetus was small for gestational age (SGA), a theoretical consequence of reductions in arterial pressure, was not seen. The rate of SGA, defined as below the 10^th percentile, was slightly higher in the treatment group (11.2% vs. 10.4%), but the difference did not approach significance (P = 0.76).
