Of patients with symptomatic, obstructive hypertrophic cardiomyopathy treated with the investigational oral agent mavacamten, more than twice as many, compared with placebo, had a very large improvement from baseline in their summary quality of life score after 30 weeks of treatment in a pivotal trial with 194 patients evaluable for this endpoint.

The trial’s health-related quality of life assessment, the Kansas City Cardiomyopathy Questionnaire (KCCQ), also showed an average improvement of more than 9 points, compared with placebo, in summary KCCQ scores among 98 mavacamten-treated patients, and a nearly 15-point improvement from baseline that represents a “moderate to large” improvement in overall health-related quality of life, John A. Spertus, MD, said at the annual scientific sessions of the American College of Cardiology.
 

Largest drug benefit ever seen in KCCQ

The 9-point average incremental improvement on mavacamten, a selective cardiac myosin inhibitor, compared with placebo-treated patients, is “the largest drug-mediated benefit we’ve ever observed on the KCCQ,” said Dr. Spertus, who spearheaded development of the KCCQ. Concurrently with his report the results also appeared online in the Lancet.

“Given the strength of the data, I’d reach for this drug early” to treat patients with obstructive hypertrophic cardiomyopathy (HCM), added Dr. Spertus, a professor and cardiovascular outcomes researcher at the University of Missouri–Kansas City and clinical director of outcomes research at Saint Luke’s Mid America Heart Institute, also in Kansas City.

No available treatment for obstructive HCM has had “as vigorous an assessment of impact on health status,” and the study that supplied the data he and his associates analyzed, EXPLORER-HCM, is “the largest trial ever done” in patients with HCM, he added.

Management guidelines for HCM released last year by the ACC and American Heart Association named beta-blockers “first-line” medical therapy for the disorder, with the calcium channel blockers verapamil or diltiazem named as “reasonable alternatives” to beta-blockers. However, these commonly used agents have “limited” evidence supporting health-status benefits in patients with HCM, Dr. Spertus and coauthors wrote in their report.
 

Longer follow-up needed

“This is an important study,” commented Matthew W. Martinez, MD, director of sports cardiology and a HCM specialist at Morristown (N.J.) Medical Center. But “given the longevity of HCM we need follow-up that goes beyond 30 weeks,” he said as designated discussant for the report.

EXPLORER-HCM randomized 251 patients with symptomatic obstructive HCM at 68 centers in 13 countries during 2018-2019. The 30-week trial’s primary outcome was a composite to assess clinical response, compared with baseline, that included a 1.5-mL/kg per min or greater increase in peak oxygen consumption (pVO₂) and at least one New York Heart Association (NYHA) functional class reduction; or a 3.0 mL/kg per min or greater improvement in pVO₂ and no worsening of NYHA class.

Patients averaged about 59 years of age, about 60% were men, and their pVO2 at entry averaged about 20 mL/kg per min. About 73% were in NYHA functional class II, with the remainder in functional class III. Patients received mavacamten as a once-daily oral dose that gradually up-titrated during the trial to reach targeted reductions in each patient’s plasma levels of the drug and in their left ventricular outflow tract gradient.

The results showed that, after 30 weeks on treatment, the primary endpoint was reached by 37% of 123 patients on mavacamten and by 17% of 128 patients on placebo, a significant difference in an intention-to-treat analysis. About 70% of patients completed their KCCQ after 30 weeks, which meant that fewer patients were in the quality of life analyses, according to the report that was published in The Lancet .

Based on these results the drug is now under consideration for approval by the Food and Drug Administration, with a decision expected by early 2022.
 

Benefit fades quickly when mavacamten stops

More detailed analysis of quality of life findings in the new report also showed that, while average KCCQ scores (both overall summary score and clinical summary score) steadily improved with mavacamten treatment, compared with control patients, through 18 weeks on treatment, the scores then roughly plateaued out to 30 weeks. This was followed by a sharp reversal back down to baseline levels and similar to control patients 8 weeks after stopping mavacamten, suggesting that the drug’s benefit quickly fades off treatment and hence must be taken chronically.

The responder analysis showed that 9% of patients on mavacamten had a worsening in their KCCQ overall summary scores by more than 5 points after 30 weeks, compared with 23% of the control patients. In contrast, a very large improvement in KCCQ score, defined as a rise of at least 20 points from baseline after 30 weeks, occurred in 36% of those who received mavacamten and in 15% of the controls. The between-group difference indicates a number needed to treat with mavacamten of roughly five to produce one additional patient with a very large improvement in KCCQ overall summary score, Dr. Spertus noted.

By design, all patients enrolled in EXPLORER-HCM had a left ventricular ejection fraction of at least 55%. During treatment, seven of the mavacamten-treated patients and two in the control arm had a transient decrease in their left ventricular ejection fraction to below 50%, although this later normalized in all affected patients. “An initial criticism” of the trial was that a significant percentage of mavacamten patients “developed left ventricular dysfunction” noted Dr. Martinez, but Dr. Spertus highlighted the poor apparent correlation between this phenomenon and quality of life self-assessment. Six of the seven patients on mavacamten who had a transient drop in their left ventricular ejection fraction had very large improvements in their KCCQ summary scores, Dr. Spertus reported.

Hypertrophic cardiomyopathy is a myocardial disorder characterized by primary left ventricular hypertrophy. Although a complex disease, HCM is broadly defined by pathologically enhanced cardiac actin-myosin interactions that result in hypercontractility, diastolic abnormalities, and dynamic left ventricular outflow tract obstruction. Mavacamten is a first-in-class, small-molecule, selective allosteric inhibitor of cardiac myosin ATPase developed to target the underlying pathophysiology of HCM by reducing actin-myosin cross-bridge formation, thereby reducing contractility and improving myocardial energetics.

EXPLORER-HCM was sponsored by MyoKardia, the company developing mavacamten and a subsidiary of Bristol-Myers Squibb. Dr. Spertus has been a consultant to MyoKardia, as well as to Abbott, Amgen, Bayer, Janssen, Merck, and Novartis. He has received research support from Abbott Vascular, and he holds the copyright for the KCCQ. Dr. Martinez has been a consultant to and received honoraria from Bristol-Myers Squibb.

Medtronic has stopped the sale of its Heartware Ventricular Assist Device (HVAD) system and is advising that physicians cease implanting the device because problems with an internal pump can lead to death or serious injuries.

“There is an increased risk of neurological adverse events and mortality associated with the internal pump,” the U.S. Food and Drug Administration announced today.

There is also a potential for the internal pump to stop, and there may be delay or failure to restart. “Both problems may lead to death or serious injuries,” the agency said.

Between January 2009 and April 22, 2021, Medtronic received a total of 106 complaints involving delay or failure to restart with the HVAD pump. Of these, 26 complaints involved HVAD devices operating under normal conditions (dual stator mode) and 80 involved devices operating in a back-up mode (single stator mode) that allows for continued pump function if electrical continuity between the pump and controller is interrupted.

Of the 26 complaints that occurred under normal conditions, four resulted in patient death and five led to urgent explant. Of the 80 complaints that occurred in single stator mode, 10 deaths and eight explants were reported to Medtronic, according to an urgent medical device communication letter issued by the company today.

“Considering these findings and given the availability of alternative devices such as the Abbott HeartMate 3, Medtronic has made the decision to stop the distribution and sale of the HVAD System,” the letter says. “Medtronic advises that there be no further implantations of the HVAD System.”

Medtronic undertook a previous recall of the Heartware HVAD system in February, focusing on batteries, power, datalink cables, and other peripheral equipment, because of the “risk of wear and tear of the connector plugs (power sources, data cable, and alarm adapter), which could cause damage to the controller port metal pins (for example, bent pins).” The FDA deemed that recall Class I, the most serious category of safety alert, in April.

The company noted that patients who currently have an HVAD implant “may require support for many years,” and that it is moving as quickly as possible to create a plan to guide the ongoing support for patients, caregivers, and health care professionals.

In response to the restart failure issue and evolving data about neurologic risks associated with the HVAD pump, Medtronic said it engaged an Independent Practitioner Quality Panel (IPQP), composed of cardiologists, surgeons, and VAD coordinators, to advise on recommendations for appropriate patient management. Based on information collected to date and IPQP input, Medtronic is recommending that physicians continue following best clinical practices and manage patients implanted with the HVAD pump according to the recommendations in the Instructions for Use (IFU).

“Prophylactic explant of the HVAD™ device is not recommended, as risks associated with explantation may outweigh the potential benefits,” the letter says. “The decision regarding explant and exchange of the HVAD™ pump should be made by physicians on a case-by-case basis, considering the patient’s clinical condition and surgical risks. If a physician determines that pump exchange is appropriate, we recommend exchanging to an alternative commercial LVAD.”

For patients in urgent need of an LVAD, Medtronic said physicians should use an alternative commercial LVAD or, if one is not available, that “a Patient Information form is required to be completed by you and your patient to acknowledge the risks of an HVAD implant prior to implanting your HVAD inventory.”

Today’s letter also provides recommendations on blood pressure management goals and anticoagulation. For any other questions or concerns, physicians should contact the Medtronic Office of Medical Affairs at: [email protected].

Medtronic issued another urgent letter in December 2020, warning physicians that a subset of HVAD devices included an internal pump component from three specific lots that increased the risk for restart failure. At that time, the company had not been able to pinpoint a root cause of the pump restart failure.

Consistent with the December 2020 notice, the rate of failure among pumps outside of the subset of three specific lots currently remains at about 0.4%, according to today’s notice.

Although Medtronic has identified the root cause and mitigations for pumps within the three specific lots, it has not been able to identify a root cause of the other restart failures reported with the HVAD pumps, the company said.

Although recent trial results have established the sodium glucose cotransporter 2 inhibitors dapagliflozin and empagliflozin as a key new part of the recommended multidrug treatment regimen for patients with heart failure with reduced ejection fraction, the current U.S. cost for dapagliflozin means it has merely “intermediate” value when it comes to cost-effectiveness.

adventtr/iStock/Getty Images Plus

A typical regimen with dapagliflozin to treat patients with heart failure with reduced ejection fraction (HFrEF) costs about $474/month or roughly $5,700/year based on Medicare pricing. After factoring in the incremental clinical benefits producing by dapagliflozin seen in the DAPA-HF pivotal trial that helped establish its role, this price produces a cost per quality-adjusted life-year (QALY) gain of about $84,000, which puts dapagliflozin squarely in the intermediate range for value set in 2014 by a task force of the American College of Cardiology and the American Heart Association.

This cost-effectiveness value depends largely on the proven efficacy of dapagliflozin (Farxiga) for decreasing the incidence of cardiovascular death among treated patients with HFrEF, and puts the drug’s value roughly on par with another agent recently approved to treat such patients, sacubitril/valsartan (Entresto), which carries a cost-effectiveness value of about $45,000/QALY.

The U.S. cost per QALY for dapagliflozin treatment of patients with HFrEF dwarfed the value numbers calculated for several other countries that were generally one-tenth this size. This disparity stemmed from both the relatively high price for dapagliflozin in the U.S. compared with other countries – nearly tenfold higher – and relatively higher costs for all types of U.S. medical care, Justin T. Parizo, MD, and coauthors said in a recent report. But the cost, and hence the cost per QALY, of dapagliflozin may soon drop because certain patents on the drug expired in October 2020, added Dr. Parizo, a cardiologist at Stanford (Calif.) University, and associates. Despite the expired patents, as of June 2021 no generic form of dapagliflozin appeared available for U.S. sale.
 

Medicare patients pay about $1,630/year out-of-pocket

“A key caveat” to this finding for dapagliflozin is that being cost-effective “is not by itself a mandate for routine clinical use,” Derek S. Chew, MD, and Daniel B. Mark, MD, said in an editorial that accompanied the report.

A major stumbling block for widespread U.S. prescribing of dapagliflozin to patients with HFrEF is its overall price tag for U.S. patients, estimated at $12 billion/year, as well as an out-of-pocket annual cost for individual Medicare patients of roughly $1,630/year. Adding this out-of-pocket cost to the copay for sacubitril/valsartan and two other much less expensive drug classes that together form the current mainstay, quadruple-drug regimen for HFrEF treatment means a potential annual cost paid by each Medicare patient of about $3,000, wrote Dr. Chew, a cardiologist, and Dr. Mark, a cardiologist and professor, both at Duke University, Durham, N.C.

They cited the precedent of the “unexpectedly slow” and “anemic” uptake of sacubitril/valsartan since its U.S. approval in 2015, a cost-effective agent with “comparable clinical effectiveness” to dapagliflozin. “Even with full inclusion [of sacubitril/valsartan] on formularies and elimination of preapproval requirements, use remains very low, and patient-borne out-of-pocket costs may be a key factor,” wrote Dr. Chew and Dr. Mark. They cited a results from a study that showed abandonment of new prescriptions at retail U.S. pharmacies spiked to a 60% rate when out-of-pocket cost exceeded $500.
 

More than what patients ‘can afford or are willing to spend’

The estimated $3,000-plus total out-of-pocket cost currently borne by some Medicare beneficiaries with HFrEF who have to shell out for both sacubitril/valsartan and dapagliflozin “appears to substantially exceed what many patients with heart failure can afford or are willing to spend,” wrote Dr. Chew and Dr. Mark.

Dr. Parizo and coauthors developed their cost-effectiveness model for dapagliflozin in treating HFrEF using primarily data collected in the DAPA-HF trial, which proved the efficacy of the drug for reducing cardiovascular deaths or acute heart failure events that led to hospitalization or intravenous outpatient treatment in more than 4,700 randomized patients with HFrEF. The trial enrolled roughly similar numbers of patients with or without type 2 diabetes.

The model showed an overall incremental cost-effectiveness ratio of $83,650/QALY, which was about the same regardless of whether patients also had type 2 diabetes. On a more granular level, the cost-effectiveness value estimate was $78,483/QALY in patients with mild health-status impairment due to their heart failure, and $97,608/QALY in patients with moderate impairment, a finding that underscores the importance of starting dapagliflozin treatment early in the course of HFrEF when disease effects are less severe. The analysis could not address value in patients with more advanced heart failure and in New York Heart Association functional class IV because fewer than 1% of patients in DAPA-HF were in this category.

Drug cost was a major determinant of cost-effectiveness. A 50% drop in cost from the Medicare benchmark of $473.64/month resulted in an incremental cost-effectiveness ratio of about $45,000/QALY (putting it into the high-value category based on the 2014 ACC/AHA formula), while a 50% rise in price yielded a value of nearly $123,000/QALY (still in the intermediate range, which spans from $50,000/QALY to $150,000/QALY). No other cost parameters had a meaningful effect on the cost-effectiveness calculation. The analyses also showed that using the basic cost assumptions, treatment with dapagliflozin needs to persist and remain effective for at least 44 months to produce a cost per QALY that’s less than $150,000. The authors stressed that their analysis considered heart failure effects and did not account for added benefit from treatment with dapagliflozin on preservation of renal function.

While it’s indisputable that treatment with dapagliflozin decreases health care costs by, for example, reducing hospitalizations for heart failure, each hospitalization costs just over $12,000, according to the assumptions made by Dr. Parizo and coauthors. But given dapagliflozin’s impact on this outcome, this cost saving translates into about $500/patient during 18 months on treatment (the median duration of treatment in DAPA-HF), which means the savings barely counterbalances the current cost of dapagliflozin treatment for 1 month, noted Dr. Chew and Dr. Mark.

The DAPA-HF trial was sponsored by AstraZeneca, the company that markets dapagliflozin (Farxiga). Dr. Parizo had no disclosures and none of his coauthors had a relationship with AstraZeneca. Dr. Chew had no disclosures. Dr. Mark has received research grants from HeartFlow, Mayo Clinic, and Merck.

Although recent trial results have established the sodium glucose cotransporter 2 inhibitors dapagliflozin and empagliflozin as a key new part of the recommended multidrug treatment regimen for patients with heart failure with reduced ejection fraction, the current U.S. cost for dapagliflozin means it has merely “intermediate” value when it comes to cost-effectiveness.

A typical regimen with dapagliflozin to treat patients with heart failure with reduced ejection fraction (HFrEF) costs about $474/month or roughly $5,700/year based on Medicare pricing.

People with prediabetes, defined by having a hemoglobin A1c of 5.7%-6.4%, had a significantly increased rate of atherosclerotic cardiovascular disease events and incident chronic kidney disease in a study of nearly 337,000 people included in the UK Biobank database.

The findings suggest that people with prediabetes have “heightened risk even without progression to type 2 diabetes,” Michael C. Honigberg, MD, said at the annual scientific sessions of the American College of Cardiology.

“Hemoglobin A1c may be better considered as a continuous measure of risk rather than dichotomized” as either less than 6.5%, or 6.5% or higher, the usual threshold defining people with type 2 diabetes, said Dr. Honigberg, a cardiologist at Massachusetts General Hospital in Boston.
 

‘Prediabetes is not a benign entity’

“Our findings reinforce the notion that A1c represents a continuum of risk, with elevated risks observed, especially for atherosclerotic cardiovascular disease [ASCVD], at levels where some clinicians wouldn’t think twice about them. Prediabetes is not a benign entity in the middle-aged population we studied,” Dr. Honigberg said in an interview. “Risks are higher in individuals with type 2 diabetes,” he stressed, “however, prediabetes is so much more common that it appears to confer similar cardio, renal, and metabolic risks at a population level.”

Results from prior observational studies also showed elevated incidence rate of cardiovascular disease events in people with prediabetes, including a 2010 report based on data from about 11,000 U.S. residents, and in a more recent meta-analysis of 129 studies involving more than 10 million people. The new report by Dr. Honigberg “is the first to comprehensively evaluate diverse cardio-renal-metabolic outcomes across a range of A1c levels using a very large, contemporary database,” he noted. In addition, most prior reports did not include chronic kidney disease as an examined outcome.

The primary endpoint examined in the new analysis was the combined incidence during a median follow-up of just over 11 years of ASCVD events (coronary artery disease, ischemic stroke, or peripheral artery disease), CKD, or heart failure among 336,709 adults in the UK Biobank who at baseline had none of these conditions nor type 1 diabetes.

The vast majority, 82%, were normoglycemic at baseline, based on having an A1c of less than 5.7%; 14% had prediabetes, with an A1c of 5.7%-6.4%; and 4% had type 2 diabetes based on an A1c of at least 6.5% or on insulin treatment. Patients averaged about 57 years of age, slightly more than half were women, and average body mass index was in the overweight category except for those with type 2 diabetes.

The primary endpoint, the combined incidence of ASCVD, CKD, and heart failure, was 24% among those with type 2 diabetes, 14% in those with prediabetes, and 8% in those who were normoglycemic at entry. Concurrently with the report, the results appeared online. Most of these events involved ASCVD, which occurred in 11% of those in the prediabetes subgroup (roughly four-fifths of the events in this subgroup), and in 17% of those with type 2 diabetes (nearly three-quarters of the events in this subgroup).

In an analysis that adjusted for more than a dozen demographic and clinical factors, the presence of prediabetes linked with significant increases in the incidence rate of all three outcomes compared with people who were normoglycemic at baseline. The analysis also identified an A1c level of 5.0% as linked with the lowest incidence of each of the three adverse outcomes. And a very granular analysis suggested that a significantly elevated risk for ASCVD first appeared when A1c levels were in the range of 5.4%-5.7%; a significantly increased incidence of CKD became apparent once A1c was in the range of 6.2%-6.5%; and a significantly increased incidence of heart failure began to manifest once A1c levels reached at least 7.0%.

Need for comprehensive cardiometabolic risk management

The findings “highlight the importance of identifying and comprehensively managing cardiometabolic risk in people with prediabetes, including dietary modification, exercise, weight loss and obesity management, smoking cessation, and attention to hypertension and hypercholesterolemia,” Dr. Honigberg said. While these data cannot address the appropriateness of using novel drug interventions in people with prediabetes, they suggest that people with prediabetes should be the focus of future prevention trials testing agents such as sodium-glucose cotransporter 2 inhibitors.

“These data help us discuss risk with patients [with prediabetes], and reemphasize the importance of guideline-directed preventive care,” said Vijay Nambi, MD, PhD, a preventive cardiologist and lipid specialist at Baylor College of Medicine and the Michael E. DeBakey VA Medical Center in Houston, who was not involved with the study.

An additional analysis reported by Dr. Honigberg examined the risk among people with prediabetes who also were current or former smokers and in the top tertile of the prediabetes study population for systolic blood pressure, high non-HDL cholesterol, and C-reactive protein (a marker of inflammation). This very high-risk subgroup of people with prediabetes had incidence rates for ASCVD events and for heart failure that tracked identically to those with type 2 diabetes. However. the incidence rate for CKD in these high-risk people with prediabetes remained below that of patients with type 2 diabetes.

The vast majority, 82%, were normoglycemic at baseline, based on having an A1c of less than 5.7%; 14% had prediabetes, with an A1c of 5.7%-6.4%; and 4% had type 2 diabetes based on an A1c of at least 6.5% or on insulin treatment. Patients averaged about 57 years of age, slightly more than half were women, and average body mass index was in the overweight category except for those with type 2 diabetes.

The primary endpoint, the combined incidence of ASCVD, CKD, and heart failure, was 24% among those with type 2 diabetes, 14% in those with prediabetes, and 8% in those who were normoglycemic at entry. Concurrently with the report, the results appeared online. Most of these events involved ASCVD, which occurred in 11% of those in the prediabetes subgroup (roughly four-fifths of the events in this subgroup), and in 17% of those with type 2 diabetes (nearly three-quarters of the events in this subgroup).

In an analysis that adjusted for more than a dozen demographic and clinical factors, the presence of prediabetes linked with significant increases in the incidence rate of all three outcomes compared with people who were normoglycemic at baseline. The analysis also identified an A1c level of 5.0% as linked with the lowest incidence of each of the three adverse outcomes. And a very granular analysis suggested that a significantly elevated risk for ASCVD first appeared when A1c levels were in the range of 5.4%-5.7%; a significantly increased incidence of CKD became apparent once A1c was in the range of 6.2%-6.5%; and a significantly increased incidence of heart failure began to manifest once A1c levels reached at least 7.0%.

Need for comprehensive cardiometabolic risk management

The findings “highlight the importance of identifying and comprehensively managing cardiometabolic risk in people with prediabetes, including dietary modification, exercise, weight loss and obesity management, smoking cessation, and attention to hypertension and hypercholesterolemia,” Dr. Honigberg said. While these data cannot address the appropriateness of using novel drug interventions in people with prediabetes, they suggest that people with prediabetes should be the focus of future prevention trials testing agents such as sodium-glucose cotransporter 2 inhibitors.

“These data help us discuss risk with patients [with prediabetes], and reemphasize the importance of guideline-directed preventive care,” said Vijay Nambi, MD, PhD, a preventive cardiologist and lipid specialist at Baylor College of Medicine and the Michael E. DeBakey VA Medical Center in Houston, who was not involved with the study.

An additional analysis reported by Dr. Honigberg examined the risk among people with prediabetes who also were current or former smokers and in the top tertile of the prediabetes study population for systolic blood pressure, high non-HDL cholesterol, and C-reactive protein (a marker of inflammation). This very high-risk subgroup of people with prediabetes had incidence rates for ASCVD events and for heart failure that tracked identically to those with type 2 diabetes. However. the incidence rate for CKD in these high-risk people with prediabetes remained below that of patients with type 2 diabetes.

Dr. Honigberg had no disclosures. Dr. Nambi has received research funding from Amgen, Merck, and Roche.

Myocarditis is present in a small percentage of competitive athletes after COVID-19 infection, even in those without symptoms, new research suggests.

In a cohort study of 1,597 competitive collegiate athletes undergoing comprehensive cardiovascular testing in the United States, the prevalence of clinical myocarditis based on a symptom-based screening strategy was only 0.31%.

But screening with cardiac MRI increased the prevalence of clinical and subclinical myocarditis by a factor of 7.4, to 2.3%, the authors reported.

The findings are published online May 27, 2021, in JAMA Cardiology.

“It was the largest study to evaluate college athletes who have had COVID with extensive cardiac testing, including MRI, and this gave us a very objective look at the cardiac findings, as they were not purely based upon a subjective evaluation of symptoms,” lead investigator Curt J. Daniels, MD, professor at Ohio State University Wexner Medical Center, Columbus, said in an interview.

“Unfortunately, our study showed that athletes can be asymptomatic, or at least not report symptoms. This is a very subjective feature, and we don’t know if they don’t report symptoms because they didn’t want to get tested. That is why we took a very objective approach,” Dr. Daniels said.

The finding that more than half of the asymptomatic athletes had myocarditis, or as the investigators called it, “subclinical myocarditis,” was a surprise, he acknowledged.

“More than half of the athletes found to have myocarditis reported no symptoms, and yes, that was a surprise, because prior to this study, the protocols that had been published stated that you had to have symptoms to even enter into the protocol for cardiac MRI. But, as our ... paper shows, if we had followed that protocol, we only would have found about 5 cases of myocarditis, as opposed to the total of 37 we found with cardiac MRI,” Dr. Daniels said.

In October 2020, the American College of Cardiology’s Sports and Exercise Council recommended that cardiac MRI be limited to athletes who exhibited symptoms as part of their guide to ensuring a safe return to play.

As reported by this news organization the council recommended a tiered approach to screening based on the presence of symptoms, followed by electrocardiography, injury biomarkers, and echocardiography. Any abnormalities detected were to be further characterized by the selective use of cardiac MRI.

At the time, there were relatively few data to support the recommendations, and all stakeholders called for larger datasets to better drive informed recommendations in the future.

In the current study, Dr. Daniels and associates conducted comprehensive cardiac screening – including ECG, troponin testing, echocardiography, and cardiac MRI – of 1,597 college athlete survivors of COVID-19.

The athletes were part of the Big Ten athletic conference, which consists of 13 major American universities.

Cardiac MRI revealed that 37 (2.3%) of these athletes demonstrated diagnostic criteria for COVID-19 myocarditis; of these, 20 had no cardiovascular symptoms and had normal ECGs, echocardiography, and troponin test results.

“These patients would not have been identified without CMR imaging. If we were going according to the older protocol, we would not have made this discovery. Cardiac MRI is the most sensitive and specific test for myocardial inflammation, there is no argument about that,” Dr. Daniels said.

The catch is, cardiac MRI is expensive and often difficult to access, especially in remote, rural, or other underserviced areas.

“You can’t get an MRI for every person who has had COVID, it’s just not feasible,” Dr. Daniels said. “We are not advocating that everybody get an MRI. But we do hope that our study creates awareness among clinicians and athletes themselves that if you’ve had COVID, even if you’re asymptomatic, there may be some heart changes. So be aware when you start to exercise again, if you have any symptoms, pause and seek medical care.”
 

Kudos to the sports cardiology community

In an accompanying editorial, James E. Udelson, MD, Ethan J. Rowin, MD, and Barry J. Maron, MD, from the CardioVascular Center at Tufts Medical Center, Boston, applauded the sports cardiology community for its diligence in acquiring and publishing data about the post–COVID-19 prevalence of cardiac abnormalities in competitive athletes.

“It is a real tribute to the sports cardiology community. There has been an amazing growth of information, and they not only gathered this information, they analyzed and published it, starting out with a study of 29 or 30 athletes, and now thousands,” Dr. Udelson said in an interview.

At the start of the pandemic, it appeared that 15%-20% of athletes had myocarditis, and athletic conferences were discussing canceling sports events.

However, with greater numbers comes a more accurate picture of the extent of the problem.

“Once you get thousands of subjects in these studies, you can hone in on what the real number is, so now we understand that if you screen everybody with a cardiac MRI, 1%, 2%, or 3% will have some evidence of what looks like myocarditis,” he said.

Dr. Udelson agreed that doing cardiac imaging in everyone is not feasible.

“This study looked at a very large number of people who all had an MRI, but that doesn’t mean everyone should have them. If you just do an echo, an EKG, and a troponin test, and if everything is normal, which is kind of what current recommendations are, this paper tells us that we are going to miss one or two people out of a hundred, and that might be okay,” he said. “So, if you are at a huge university that has a large medical center and you want to screen all your athletes with MRI, great. But if you’re at a high school in a remote area, you know that the alternative, not having an MRI, isn’t so bad, either.”

Pericardial fat is associated with a heightened risk for heart failure, particularly in women, new research suggests.

In a prospective cohort study of nearly 7,000 individuals, excess pericardial fat was linked to a higher risk for heart failure, even after adjustment for established risk factors for heart failure.

Women with high pericardial fat volume (PFV), defined as more than 70 cm³ or 2.4 fluid ounces, had double the risk of developing heart failure. For men, high PFV, defined as more than 120 cm³ or 4.0 fluid ounces, was associated with a 50% increase in the risk for heart failure.

The findings were published in the Journal of the American College of Cardiology.

“People will ask why should they measure fat around the heart. Why can’t they just take the waist circumference or body mass index as a measure for increased risk?” lead author Satish Kenchaiah, MD, MPH, Icahn School of Medicine at Mount Sinai, New York, said in an interview.

“Yet, when we adjusted for waist circumference, hip circumference, waist to hip ratio, and other known variables, pericardial fat was still associated with an increased risk of heart failure. This tells me that it is not just overall fat in the body but something about its location around the heart that is playing a role,” Dr. Kenchaiah said.

“Now that we have found an association between any amount of fat around the pericardium and heart failure, it gives us an impetus to build future research on identifying how exactly these fat deposits influence the development of cardiomyopathy,” he said.

Dr. Kenchaiah and colleagues investigated the association of pericardial fat with incident heart failure by examining chest CT scans from 6,785 participants (3,584 women and 3,201 men aged 45-84 years) in the Multi-Ethnic Study of Atherosclerosis.

The participants were from four different ethnic groups: 38% were White; 28% were Black, 22% were Hispanic, and 12% were Chinese American. They were recruited between July 17, 2000, and Aug. 31, 2002, from six communities in the United States: Baltimore and Baltimore County; Chicago; Forsyth County, N.C.; Los Angeles County northern Manhattan and the Bronx, New York; and St. Paul, Minn.

All participants were free of cardiovascular disease at baseline.

The researchers followed participants for more than 17 years. During this time, 385 (5.7%; 164 women and 221 men) developed newly diagnosed heart failure.

In women, the hazard ratio for every 42 cm³ increase in PFV was 1.44 (95% confidence interval, 1.21-1.71; P < .001). In men, the HR was 1.13 (95% CI, 1.01-1.27; P = .03).

High PVF conferred a twofold greater risk for heart failure in women (HR, 2.06; 95% CI, 1.48-2.87; P < .001) and a 53% higher risk in men (HR, 1.53; 95% CI, 1.13-2.07; P = .006).

These associations remained significant after further adjustment for circulating markers of systemic inflammation (that is, C-reactive protein and interleukin-6), and abdominal subcutaneous or visceral fat.

They also found that the heightened risk persisted, even after adjustment for established risk factors for heart failure, such as age, cigarette smoking, alcohol consumption, sedentary lifestyle, high blood pressure, high blood sugar, high cholesterol, and myocardial infarction.

Results were similar among all of the ethnic groups studied.
 

A surprise finding

“The most surprising part of this study was that the risk for heart failure with increased pericardial fat does not seem to be explained by obesity and systemic inflammation alone,” Andreas P. Kalogeropoulos, MD, MPH, PhD, Stony Brook (N.Y.) University, said in an interview.

“If pericardial fat was merely a proxy for increased visceral fat, one would expect the association of pericardial fat with heart failure risk to go away after factoring in abdominal CT findings, which was not the case here. Also, accounting for inflammatory markers did not change things dramatically. However, we need to be careful here, as abdominal CT scans have not been done simultaneously with the pericardial fat scans in the study,” said Dr. Kalogeropoulos, who coauthored an accompanying editorial with Michael E. Hall, MD, University of Mississippi Medical Center, Jackson.

The other striking finding, although not entirely surprising, was the stronger association of pericardial fat with heart failure risk in women, he noted.

“Although several clues have been reported pointing to women being more sensitive to the adverse cardiac effects of pericardial fat, this is the first large prospective study to connect the dots and show much higher risk in women in a convincing way. For the record, this is the first prospective study to show the connection between pericardial fat and heart failure risk altogether,” Dr. Kalogeropoulos said.

“Obviously, we need to do more work to see how we can use the important findings of Kenchaiah and colleagues to reduce risk for heart failure among patients with increased pericardial fat, especially women. For starters, we would need a way to identify these patients,” he said. “In this aspect, it is encouraging that pericardial fat can be measured in low-radiation CT scans, similar to those used for coronary calcium, and that automation technology to speed up pericardial fat measurements is already in the pipeline.

“The next step would be to see what kind of interventions would reduce risk for heart failure in these patients,” he added. “Weight loss would be an obvious thing, but novel agents with favorable cardiometabolic effects, like newer antidiabetic medications, are intriguing options, too.”

The study was supported by the National Heart, Lung, and Blood Institute and the National Institutes of Health. Dr. Kenchaiah and Dr. Kalogeropoulos reported no relevant financial relationships.

The participants were from four different ethnic groups: 38% were White; 28% were Black, 22% were Hispanic, and 12% were Chinese American. They were recruited between July 17, 2000, and Aug. 31, 2002, from six communities in the United States: Baltimore and Baltimore County; Chicago; Forsyth County, N.C.; Los Angeles County northern Manhattan and the Bronx, New York; and St. Paul, Minn.

All participants were free of cardiovascular disease at baseline.

The researchers followed participants for more than 17 years. During this time, 385 (5.7%; 164 women and 221 men) developed newly diagnosed heart failure.

In women, the hazard ratio for every 42 cm³ increase in PFV was 1.44 (95% confidence interval, 1.21-1.71; P < .001). In men, the HR was 1.13 (95% CI, 1.01-1.27; P = .03).

High PVF conferred a twofold greater risk for heart failure in women (HR, 2.06; 95% CI, 1.48-2.87; P < .001) and a 53% higher risk in men (HR, 1.53; 95% CI, 1.13-2.07; P = .006).

These associations remained significant after further adjustment for circulating markers of systemic inflammation (that is, C-reactive protein and interleukin-6), and abdominal subcutaneous or visceral fat.

They also found that the heightened risk persisted, even after adjustment for established risk factors for heart failure, such as age, cigarette smoking, alcohol consumption, sedentary lifestyle, high blood pressure, high blood sugar, high cholesterol, and myocardial infarction.

Results were similar among all of the ethnic groups studied.
 

A surprise finding

“The most surprising part of this study was that the risk for heart failure with increased pericardial fat does not seem to be explained by obesity and systemic inflammation alone,” Andreas P. Kalogeropoulos, MD, MPH, PhD, Stony Brook (N.Y.) University, said in an interview.

“If pericardial fat was merely a proxy for increased visceral fat, one would expect the association of pericardial fat with heart failure risk to go away after factoring in abdominal CT findings, which was not the case here. Also, accounting for inflammatory markers did not change things dramatically. However, we need to be careful here, as abdominal CT scans have not been done simultaneously with the pericardial fat scans in the study,” said Dr. Kalogeropoulos, who coauthored an accompanying editorial with Michael E. Hall, MD, University of Mississippi Medical Center, Jackson.

The other striking finding, although not entirely surprising, was the stronger association of pericardial fat with heart failure risk in women, he noted.

“Although several clues have been reported pointing to women being more sensitive to the adverse cardiac effects of pericardial fat, this is the first large prospective study to connect the dots and show much higher risk in women in a convincing way. For the record, this is the first prospective study to show the connection between pericardial fat and heart failure risk altogether,” Dr. Kalogeropoulos said.

“Obviously, we need to do more work to see how we can use the important findings of Kenchaiah and colleagues to reduce risk for heart failure among patients with increased pericardial fat, especially women. For starters, we would need a way to identify these patients,” he said. “In this aspect, it is encouraging that pericardial fat can be measured in low-radiation CT scans, similar to those used for coronary calcium, and that automation technology to speed up pericardial fat measurements is already in the pipeline.

“The next step would be to see what kind of interventions would reduce risk for heart failure in these patients,” he added. “Weight loss would be an obvious thing, but novel agents with favorable cardiometabolic effects, like newer antidiabetic medications, are intriguing options, too.”

The study was supported by the National Heart, Lung, and Blood Institute and the National Institutes of Health. Dr. Kenchaiah and Dr. Kalogeropoulos reported no relevant financial relationships.

Transcatheter mitral valve repair with the PASCAL device showed high rates of survival and freedom from heart failure rehospitalization at 2 years in the single-arm, safety and efficacy CLASP study.

The Heart Hospital Baylor Plano

The early reductions in mitral regurgitation (MR) were sustained with 97% of patients having MR grades of 2+ or less and 78% having MR grades of 1+ or less at 2 years.

There was also evidence of left ventricular (LV) reverse remodeling and significant improvements in functional status, Molly Szerlip, MD, Baylor Scott & White Health, Plano, Texas, reported as lead author. The results were published online May 18 in JACC: Cardiovascular Interventions.

“The PASCAL transcatheter valve repair system is a favorable option for treating patients with MR,” she said in a simultaneous virtual presentation at the 2021 Congress of European Association of Percutaneous Cardiovascular Interventions (EuroPCR 2021).

The PASCAL system is not approved in the United States, but Dr. Szerlip observed that the investigators are eagerly awaiting results from the ongoing, pivotal CLASP IID/IIF trial comparing the edge-to-edge repair system with another such device, MitraClip, in 1,275 patients with functional or degenerative MR. The primary completion date is set for December 2023.

Abbott’s MitraClip has been available in the United States since 2013 and in Europe since 2008; Edwards Lifesciences received a CE mark for the PASCAL system in 2019.

“The results of the CLASP study are remarkable and indicate an additional differentiated tool ready for clinical routine,” Georg Goliasch, MD, PhD, and Philipp Bartko, MD, both from the Medical University of Vienna, write in an accompanying editorial.

As both systems target similar lesions, there might be “significant overlap in this particular patient population,” Dr. Goliasch told this news organization. From a technical perspective, the separate leaflet grasping was initially one of the advantages of the PASCAL, but this has also been recently introduced for the MitraClip.

That said, the “PASCAL device may offer a leaflet repair with decreased mechanical leaflet traction – specifically appealing to treat ventricular secondary MR – because mechanical forces applied to leaflets remain low, and the [central] spacer augments the leaflet surface in a way that reduces restrictive diastolic opening,” he added. “However, this remains highly speculative.”

The CLASP study enrolled 124 patients (56% male) with symptomatic MR grade of at least 3+ who were receiving optimal medical therapy at 14 sites in five countries. Their mean age was 75 years, 69% had functional MR (FMR), 31% had degenerative MR (DMR), and 60% were NYHA functional class III to IVa.

The primary endpoints of procedural and clinical success and adverse events at 30 days and 1-year outcomes were published last year. Echocardiographic data were available for 36 patients at 2 years with follow-up ongoing.

Composite major adverse event rates were 8.1% at 30 days, 18.5% at 1 year, and 16.9% at 2 years, driven mostly by severe bleeding at 7.3%, 11.3%, and 7.3%, respectively, Dr. Szerlip said.

Kaplan-Meier estimates showed 80.3% survival at 2 years (72.3% FMR, 94.3% DMR) and 84.3% freedom from heart failure rehospitalization (77.5% FMR, 97.3% DMR). The annualized HF rehospitalization rate fell to 85% at 2 years.

These results, the authors noted, hinged on minimizing residual MR. In the FMR group, 100% and 95% of patients achieved MR of 2+ or less at 1 year and 2 years, respectively, compared with 95% and 99% treated with the MitraClip in the COAPT study.

In the DMR group, 100% of patients achieved MR of 2+ or less at both 1 and 2 years, which “compares favorably to 94% from the EXPAND study at 1 year” with the MitraClip NTR and XTR systems, they write.

In CLASP, the LV end-diastolic volume decreased by 11 mL at 30 days and continued to decrease at 1 year (25 mL) and 2 years (33 mL; P < .001).

LV end-diastolic diameter (LVEDD) fell by 2.7 mm at 30 days, 3.9 mm at 1 year, and by 2.7 mm at 2 years (P = .002). At 2 years, 93% of patients were in NYHA class I or II (P < .001).

“The authors of the trial observed significant LV reverse remodeling with a decrease in LVEDD. These findings are indeed of particular interest and warrant further investigation by future studies as this has not been shown to such an extent in previous E2E [edge-to-edge] repair studies,” Dr. Goliasch said in an interview.

He raised an eyebrow, however, at the cross-trial comparisons, adding, “We should be very careful to draw any hasty conclusions considering the high proportion of missing echocardiographic data. Nevertheless, all these aspects might make the design of future studies for direct comparisons between E2E devices in the various structural aspects of mitral valve disease attractive to tailor treatment and optimize patient care.”

Dr. Szerlip and colleagues cited several study limitations including the absence of a control arm that may have contributed to a Hawthorne effect; not all patients had reached 2-year follow-up at the time of the analysis; and adjudication of events and assessment of the 6-minute walk test and quality-of-life measures were limited to 1 year based on the protocol.

The study was sponsored by Edwards Lifesciences. Dr. Szerlip reported serving as a proctor/speaker for Edwards; a national principal investigator for EFS; a speaker for Boston Scientific, and serving on steering committees for Medtronic and Abbott. Dr. Goliasch and Dr. Bartko have disclosed no relevant financial relationships.

After taking it on the chin for previously reporting Bayesian estimates, actual 2-year data from the EVOLUT Low Risk trial confirm that transcatheter aortic valve replacement (TAVR) is noninferior to surgery for the primary endpoint of death or disabling stroke.

Among 1,414 as-treated patients, Kaplan-Meier rates for all-cause death or disabling stroke at 24 months were 4.3% with TAVR and 6.3% with surgery (P = .084).

There was also no difference in the individual components of all-cause death (3.5% vs. 4.4%; log-rank P = .366) and disabling stroke (1.5% vs. 2.7%; log-rank P = .119).

Recent low-risk TAVR studies have raised questions about whether there’s a possible catch-up for surgery between 12 and 24 months, given the early mortality benefit from the less-invasive transcatheter procedure, prompting a landmark analysis, John K. Forrest, MD, said during the virtual presentation at the 2021 Congress of European Association of Percutaneous Cardiovascular Interventions, EuroPCR 2021.

“Between 1 and 2 years, there was no convergence of the Kaplan-Meier curves for death or disabling stroke,” with an incidence of 1.9% for the TAVR group and 2.1% for the surgery group (log-rank P = .742), said Dr. Forrest, of Yale University, New Haven, Conn. “The lines were almost superimposed upon each other.”

Session moderator Bernard Prendergast, MD, observed that the Bayesian analysis, which was reported in 2019 and used 12-month follow-up to predict 2-year outcomes, generated questions and criticism over whether this was an appropriate method, compared with traditional Kaplan-Meier analysis. “Indeed, some people accused the investigators of gaming it with this form of statistical analysis.”

To act as a “fact checker,” Dr. Prendergast called in Christopher Cook, MRC, from the PCR Clinical Research Group and Imperial College London. The key methodologic question, Dr. Cook said, is whether Bayesian methods accurately predict actual clinical outcomes in this randomized clinical trial. “The simple answer to this for me, is yes.”

He pointed out that the Kaplan-Meier data for the primary outcome at 2 years were, in fact, numerically better than Bayesian estimates of 5.3% in the TAVR group and 6.7% in the surgery group.

“This validates the use of the original Bayesian methods to estimate patient outcomes in low-risk TAVI patients and, indeed, it may act as an example of where Bayesian methods can be safely applied in order to fast track potentially transformative procedures and technologies to our patients,” Dr. Cook said.

The rate of disabling stroke with TAVR was 1.5% in the new analysis, up from 1.1% in the Bayesian analysis, and 2.7% with surgery, down from 3.5% in the Bayesian analysis.

All-cause mortality, also noted earlier, was 3.5% with TAVR and 4.4% with surgery, whereas the Bayesian estimate was 4.5% for each group.

Dr. Prendergast of St. Thomas’ Hospital, London, said the actual 2-year data are reassuring regarding the statistical tools used and supplement those recently reported from low-risk patients in PARTNER 3.

But, he asked, “what does this mean for practice, what does it mean for guidelines, and how long do we need to wait until we are comfortable and reassured that we can apply TAVI in younger and low-risk patients with a durable outcome?”

Dr. Forrest said that clinicians can be reassured that these patients “are doing very well” but that long-term follow-up is critical.

“We need to be realistic here. We’re really going to be interested in 5- and 10-year outcomes and potentially even thereafter,” he said. “What happens to these valves when they eventually fail? Are superior hemodynamics going to give us longer valve durability in some way or are there going to be other unforeseen things that come up 10 years out? We don’t know those answers.”

TAVR with a supra-annular, self-expanding valve (CoreValve , Evolut R, or Evolut PRO) had superior hemodynamics in the new 2-year analysis with lower aortic valve gradients (9.0 vs. 11.7 mm Hg) and larger valve areas (2.2 vs. 2.0 cm²).

Prosthesis-patient mismatch also favored TAVR, with moderate or severe mismatch occurring in 7.2% and 2.1%, respectively, compared with 19.1% and 4.9%, respectively, with surgery. “We know that this has an impact on long-term outcomes, so it’s important to note that significant difference here,” Dr. Forrest said.

The chink in TAVR’s armor remains paravalvular leak, particularly mild leak, which was significantly higher at 26.6%, compared with only 2.6% with surgery. Moderate to severe leaks were seen in 1.7% and 0.4%, respectively, reflecting the improvement in TAVR with new iterations, he said.

Surgery was also superior to TAVR with regard to the need for permanent pacemaker implantation (7.9% vs. 21.1%). This compares with Bayesian estimates of 6.7% and 23.0%, respectively.

Rates of myocardial infarction remained constant in the two analyses for the TAVR (2.2%) and surgery (1.6%) groups, whereas heart failure hospitalizations improved slightly, from 5.4% versus 7.9%, respectively, in the Bayesian analysis to 5.3% versus 7.1%, respectively, in the new analysis.

Fellow discussant Marie-Claude Morice, MD, Institute Hospitalier Jacques Cartier, Massy, France, highlighted several meta-analyses in different risk patients showing “a lot of good news,” including decreased stroke and mortality rates and the combined outcome clearly favoring TAVR.

“The remaining question is the longevity of the valve, but with 5 years’ follow-up we have for comparison [in high-risk patients], it is the same,” she said. “What this illustrates is that the tidal wave of TAVR is continuing, and we can look optimistically to the future. Is it the nonsymptomatic patients?”

Medtronic funded the study. Dr. Forrest reported grant support from, serving on the advisory board, and proctoring for Edwards Lifesciences and Medtronic. Dr. Prendergast has received grants from Edwards Lifesciences; and speaker/consultancy fees from Abbott, Anteris, and Edwards.

The chink in TAVR’s armor remains paravalvular leak, particularly mild leak, which was significantly higher at 26.6%, compared with only 2.6% with surgery. Moderate to severe leaks were seen in 1.7% and 0.4%, respectively, reflecting the improvement in TAVR with new iterations, he said.

Surgery was also superior to TAVR with regard to the need for permanent pacemaker implantation (7.9% vs. 21.1%). This compares with Bayesian estimates of 6.7% and 23.0%, respectively.

Rates of myocardial infarction remained constant in the two analyses for the TAVR (2.2%) and surgery (1.6%) groups, whereas heart failure hospitalizations improved slightly, from 5.4% versus 7.9%, respectively, in the Bayesian analysis to 5.3% versus 7.1%, respectively, in the new analysis.

Fellow discussant Marie-Claude Morice, MD, Institute Hospitalier Jacques Cartier, Massy, France, highlighted several meta-analyses in different risk patients showing “a lot of good news,” including decreased stroke and mortality rates and the combined outcome clearly favoring TAVR.

“The remaining question is the longevity of the valve, but with 5 years’ follow-up we have for comparison [in high-risk patients], it is the same,” she said. “What this illustrates is that the tidal wave of TAVR is continuing, and we can look optimistically to the future. Is it the nonsymptomatic patients?”

Medtronic funded the study. Dr. Forrest reported grant support from, serving on the advisory board, and proctoring for Edwards Lifesciences and Medtronic. Dr. Prendergast has received grants from Edwards Lifesciences; and speaker/consultancy fees from Abbott, Anteris, and Edwards.

After taking it on the chin for previously reporting Bayesian estimates, actual 2-year data from the EVOLUT Low Risk trial confirm that transcatheter aortic valve replacement (TAVR) is noninferior to surgery for the primary endpoint of death or disabling stroke.

Among 1,414 as-treated patients, Kaplan-Meier rates for all-cause death or disabling stroke at 24 months were 4.3% with TAVR and 6.3% with surgery (P = .084).

There was also no difference in the individual components of all-cause death (3.5% vs. 4.4%; log-rank P = .366) and disabling stroke (1.5% vs. 2.7%; log-rank P = .119).

Recent low-risk TAVR studies have raised questions about whether there’s a possible catch-up for surgery between 12 and 24 months, given the early mortality benefit from the less-invasive transcatheter procedure, prompting a landmark analysis, John K. Forrest, MD, said during the virtual presentation at the 2021 Congress of European Association of Percutaneous Cardiovascular Interventions, EuroPCR 2021.

“Between 1 and 2 years, there was no convergence of the Kaplan-Meier curves for death or disabling stroke,” with an incidence of 1.9% for the TAVR group and 2.1% for the surgery group (log-rank P = .742), said Dr. Forrest, of Yale University, New Haven, Conn. “The lines were almost superimposed upon each other.”

Session moderator Bernard Prendergast, MD, observed that the Bayesian analysis, which was reported in 2019 and used 12-month follow-up to predict 2-year outcomes, generated questions and criticism over whether this was an appropriate method, compared with traditional Kaplan-Meier analysis. “Indeed, some people accused the investigators of gaming it with this form of statistical analysis.”

To act as a “fact checker,” Dr. Prendergast called in Christopher Cook, MRC, from the PCR Clinical Research Group and Imperial College London. The key methodologic question, Dr. Cook said, is whether Bayesian methods accurately predict actual clinical outcomes in this randomized clinical trial. “The simple answer to this for me, is yes.”

He pointed out that the Kaplan-Meier data for the primary outcome at 2 years were, in fact, numerically better than Bayesian estimates of 5.3% in the TAVR group and 6.7% in the surgery group.

“This validates the use of the original Bayesian methods to estimate patient outcomes in low-risk TAVI patients and, indeed, it may act as an example of where Bayesian methods can be safely applied in order to fast track potentially transformative procedures and technologies to our patients,” Dr. Cook said.

The rate of disabling stroke with TAVR was 1.5% in the new analysis, up from 1.1% in the Bayesian analysis, and 2.7% with surgery, down from 3.5% in the Bayesian analysis.

All-cause mortality, also noted earlier, was 3.5% with TAVR and 4.4% with surgery, whereas the Bayesian estimate was 4.5% for each group.

Dr. Prendergast of St. Thomas’ Hospital, London, said the actual 2-year data are reassuring regarding the statistical tools used and supplement those recently reported from low-risk patients in PARTNER 3.

But, he asked, “what does this mean for practice, what does it mean for guidelines, and how long do we need to wait until we are comfortable and reassured that we can apply TAVI in younger and low-risk patients with a durable outcome?”

Dr. Forrest said that clinicians can be reassured that these patients “are doing very well” but that long-term follow-up is critical.

“We need to be realistic here. We’re really going to be interested in 5- and 10-year outcomes and potentially even thereafter,” he said. “What happens to these valves when they eventually fail? Are superior hemodynamics going to give us longer valve durability in some way or are there going to be other unforeseen things that come up 10 years out? We don’t know those answers.”

TAVR with a supra-annular, self-expanding valve (CoreValve , Evolut R, or Evolut PRO) had superior hemodynamics in the new 2-year analysis with lower aortic valve gradients (9.0 vs. 11.7 mm Hg) and larger valve areas (2.2 vs. 2.0 cm²).

Prosthesis-patient mismatch also favored TAVR, with moderate or severe mismatch occurring in 7.2% and 2.1%, respectively, compared with 19.1% and 4.9%, respectively, with surgery. “We know that this has an impact on long-term outcomes, so it’s important to note that significant difference here,” Dr. Forrest said.

Combining minimally invasive endoscopic sleeve gastroplasty with a weekly injection of the glucagonlike peptide–1 agonist semaglutide (Ozempic, Novo Nordisk) leads to significantly greater weight loss than ESG alone in patients with diabetes and excess weight who are not candidates for bariatric surgery, new research shows.

During minimally invasive ESG, a flexible endoscope equipped with an endoscopic suturing device is inserted down the esophagus and into the stomach. The endoscopist then applies the sutures to the upper portion of the stomach, minimizing its size to restrict the amount of food a patient can ingest.

“Our stomachs can stretch back a bit, but we can use the suturing device again,” explained the lead investigator of the research Anna Carolina Hoff, MD, founder and clinical director of Angioskope Brazil in São José dos Campos.

“It’s important that patients with diabetes lose as much weight as possible because, if they lose about 10% of their total body weight, they have a great improvement in their glycemic levels, and some patients can even stop taking their [antidiabetic] medications,” Dr. Hoff said in an interview.

“And we found that by adding the GLP-1 agonist [semaglutide], we could increase weight loss from, on average, about 16%-18% of total body weight with ESG alone to up to 27%, so it’s a great metabolic combination,” she noted.

Dr. Hoff presented the findings at the annual Digestive Disease Week® (DDW).

Asked to comment, Scott Kahan, MD, MPH, director, National Center for Weight and Wellness, George Washington University, Washington, cautioned that it’s still early days for minimally invasive ESG.

“It is reasonable to assume that the long-term outcomes [with ESG] won’t be as good or durable over time as with bariatric surgery, but ... we will have to see.”

However, “we know that, typically, combinations of therapeutic options work better than a one-off option, so I think the real benefit of this study – outside the specific procedure and this specific medication – is that it is a very valuable proof-of-principle study showing that combinations do work better,” Dr. Kahan said in an interview.
 

Minimally invasive endoscopic sleeve gastroplasty

ESG is a surrogate for laparoscopic sleeve gastrectomy that can offer the benefits of such a procedure to those who don’t qualify for, or don’t wish to pursue, bariatric surgery. It can be performed at an earlier stage of disease, in those with a body mass index of 30 mg/kg², whereas generally people are not offered bariatric procedures unless they have a BMI of at least 35 with comorbidities or a BMI of at least 40 if they do not have comorbidities.

Subcutaneous semaglutide is already approved for the treatment of type 2 diabetes in adults at doses of up to 1 mg/week; higher doses are needed for weight loss. Novo Nordisk has been investigating higher doses for weight loss in the STEP trial program, which is now complete, and the company has submitted the data to the Food and Drug Administration and European Medicines Agency for an additional indication of adults with obesity (BMI ≥30) or who are overweight (BMI ≥27) and who have at least one weight-related comorbidity, as an adjunct to a reduced-calorie diet and increased physical activity, with a decision expected soon.

Novo Nordisk has also developed an oral form of semaglutide, which has been approved as a once-daily agent for type 2 diabetes (Rybelsus) in doses of 7 mg and 14 mg to improve glycemic control along with diet and exercise. It is the first GLP-1 agonist available in tablet form.
 

Patients lost fat mass as well as excess weight

The Brazilian study involved 58 patients with obesity or overweight who also had diabetes and were undergoing minimally invasive ESG; they were further randomized to receive semaglutide or placebo.

The GLP-1 agonist (or sham placebo) was initiated 1 month after participants had undergone the procedure and patients were monitored each month for weight loss and type of fat loss achieved with the combination versus ESG alone. The initial dose of semaglutide used was 0.25 mg subcutaneous a week but could be titrated up to a maximum dose of 1.5 mg.

At the end of 11 months of active treatment versus placebo (12 months after ESG), patients who received additional semaglutide lost 86.3% of their excess body weight – the amount of weight patients needed to lose to reach normal BMI – compared with only 60.4% for ESG controls.

Specifically, the mean percentage total body weight loss at the end of 12 months was 25.2% for those in the combination group, compared with 18.6% for those treated with ESG alone (P < .001).

More importantly, patients in the combination group lost 12.6% of their body fat mass, compared with 9% for ESG controls, while mean A1c levels fell more in those treated with additional semaglutide compared with controls (P = .0394).

Indeed, five patients in the combination group reverted to a nondiabetic state and were able to discontinue antidiabetic medications altogether, Dr. Hoff noted.

“Our main goal is not just to lose weight but to lose body mass fat, which is very different from just losing weight,” she explained.

If patients lose weight but still maintain a high percentage of body fat mass, they have what she refers to as “sarcopenic obesity” because in this state patients have lost a lot of muscle mass but still have high levels of metabolically active visceral fat. Among many other inflammatory complexes, metabolically active visceral fat contains a large number of inflammasomes, and it is the latter that have been associated with obesity-related cancers. 

“Obesity is a progressive disease, so what we are trying to do here is buy time for patients so they do not progress to [bariatric] surgery, and this approach gives patients a chance to act earlier before obesity takes over and more metabolic consequences occur,” Dr. Hoff emphasized.

So, when combined with semaglutide, “we now have a minimally invasive procedure that can be just as successful [as surgery] and which can be made available to even more people looking to lose a significant amount of weight,” she concluded.

Dr. Hoff and Dr. Kahan have reported no relevant financial relationships.

New data show for the first time that combining the DASH (Dietary Approaches to Stop Hypertension) diet with sodium restriction decreases myocardial injury and cardiac strain, which are associated with subclinical cardiac damage and long-term cardiovascular risk.

“The benefits of healthy eating are swift and direct. High sodium is not just about taste, it causes heart strain,” Stephen Juraschek, MD, PhD, from Beth Israel Deaconess Medical Center, Boston, said in an interview.

“We should consciously follow a diet enriched with fruit and vegetables and low in sodium. Collectively, we should think about how foods are promoted in society and what is an acceptable amount of sodium for food supplies,” said Dr. Juraschek.

The findings, from a secondary analysis of the DASH-Sodium trial, were published the Journal of the American College of Cardiology.
 

Renewed focus on diet

“These data should spur a renewed focus on the critical need for widespread adoption of the DASH–low-sodium diet in the United States,” wrote the coauthors of a linked editorial.

“The challenge remains moving the DASH–low-sodium diet from the research world into the real world, where its significant health benefits can be fully realized,” they added.

The researchers evaluated the impact of the DASH diet and sodium restriction, individually and combined, on biomarkers of cardiac injury (high-sensitivity cardiac troponin I [hs-cTnI]), cardiac strain (N-terminal of the prohormone brain natriuretic peptide [NT-proBNP]), and inflammation (high-sensitivity C-reactive protein [hs-CRP]).

The DASH-Sodium trial was a controlled feeding study that enrolled 412 adults (mean age, 48 years; 56% women, 56% Black) with untreated systolic blood pressure between 120 and 159 mm Hg and diastolic blood pressure between 80 and 95 mm Hg. Mean baseline BP was 135/86 mm Hg.

Participants were randomly allocated to a typical American diet (control) or the heart-healthy DASH diet. Further, participants in both groups were assigned to each of three sodium intake levels: low (0.5 mg/kcal), medium (1.1 mg/kcal) or high (1.6 mg/kcal) for 30 days using a crossover design with washout periods in between.

Compared with the control diet, the DASH diet reduced hs-cTnI by 18% and hs-CRP by 13% with no impact on NT-proBNP.

In contrast, lowering sodium from high to low levels reduced NT-proBNP independent of diet by 19%, but did not alter hs-cTnI and mildly increased hs-CRP (9%).

Combining the DASH diet with sodium reduction lowered hs-cTnI by 20% and NT-proBNP by 23%, with no significant change in hs-CRP, compared with the high-sodium-control diet.

“Together, these findings imply that two distinct dietary strategies might improve two key pathways of subclinical cardiac damage: injury and strain,” Dr. Juraschek and colleagues wrote.

“These findings should strengthen public resolve for public policies that promote the DASH dietary pattern and lower sodium intake in the United States and globally,” they concluded.

“We need to talk about DASH more. Most adults in the U.S. have never heard of it,” Dr. Juraschek said in an interview.

“We need to promote nutrition literacy with regard to nutrition facts. Labeling is not very transparent and hard to understand. Many people don’t know where salt is hiding in their diet,” he added.

It will also be important to address disparities in access to healthy foods and food insecurity, Dr. Juraschek said.

“If we don’t address food costs and access, disparities in healthy eating will persist. Greater equity is key. We should also be mindful about populations dependent on others for meal preparation [children in schools or older adults on meal plans]. This might be regulated in ways that promote healthier eating population wide, but for these patients, they may not have autonomy to choose what they eat,” Dr. Juraschek said.

In their editorial, Neha J. Pagidipati, MD, and Laura P. Svetkey, MD, from Duke University and Duke Clinical Research Institute, Durham, N.C., said an important caveat is that the beneficial effects of diet and sodium restriction on cardiac injury and strain occurred in people without any clinical evidence of coronary artery disease or heart failure at baseline, “suggesting that this dietary combination can improve subclinical metrics of cardiac health.”

“Further, the impact on these markers was seen within weeks, indicating a relatively rapid impact on cardiac damage,” they added.

The measurement of cardiac biomarkers was supported by the National Institutes of Health/National Heart, Lung, and Blood Institute. The original DASH trial was supported by the NHLBI, the Office of Research on Minority Health, and the National Center for Research Resources. Dr. Juraschek and coauthors disclosed no relevant conflicts of interest. Dr. Pagidipati has received research support to the institution from Amgen, AstraZeneca, Boehringer Ingelheim, Eli Lilly, Novartis, Novo Nordisk, Regeneron, Sanofi, and Verily Life Sciences; and has received consultation fees from Boehringer Ingelheim, Eli Lilly, AstraZeneca, and Novo Nordisk. Dr. Svetkey has no relevant disclosures.

Compared with the control diet, the DASH diet reduced hs-cTnI by 18% and hs-CRP by 13% with no impact on NT-proBNP.

In contrast, lowering sodium from high to low levels reduced NT-proBNP independent of diet by 19%, but did not alter hs-cTnI and mildly increased hs-CRP (9%).

Combining the DASH diet with sodium reduction lowered hs-cTnI by 20% and NT-proBNP by 23%, with no significant change in hs-CRP, compared with the high-sodium-control diet.

“Together, these findings imply that two distinct dietary strategies might improve two key pathways of subclinical cardiac damage: injury and strain,” Dr. Juraschek and colleagues wrote.

“These findings should strengthen public resolve for public policies that promote the DASH dietary pattern and lower sodium intake in the United States and globally,” they concluded.

“We need to talk about DASH more. Most adults in the U.S. have never heard of it,” Dr. Juraschek said in an interview.

“We need to promote nutrition literacy with regard to nutrition facts. Labeling is not very transparent and hard to understand. Many people don’t know where salt is hiding in their diet,” he added.

It will also be important to address disparities in access to healthy foods and food insecurity, Dr. Juraschek said.

“If we don’t address food costs and access, disparities in healthy eating will persist. Greater equity is key. We should also be mindful about populations dependent on others for meal preparation [children in schools or older adults on meal plans]. This might be regulated in ways that promote healthier eating population wide, but for these patients, they may not have autonomy to choose what they eat,” Dr. Juraschek said.

In their editorial, Neha J. Pagidipati, MD, and Laura P. Svetkey, MD, from Duke University and Duke Clinical Research Institute, Durham, N.C., said an important caveat is that the beneficial effects of diet and sodium restriction on cardiac injury and strain occurred in people without any clinical evidence of coronary artery disease or heart failure at baseline, “suggesting that this dietary combination can improve subclinical metrics of cardiac health.”

“Further, the impact on these markers was seen within weeks, indicating a relatively rapid impact on cardiac damage,” they added.

The measurement of cardiac biomarkers was supported by the National Institutes of Health/National Heart, Lung, and Blood Institute. The original DASH trial was supported by the NHLBI, the Office of Research on Minority Health, and the National Center for Research Resources. Dr. Juraschek and coauthors disclosed no relevant conflicts of interest.

New data show for the first time that combining the DASH (Dietary Approaches to Stop Hypertension) diet with sodium restriction decreases myocardial injury and cardiac strain, which are associated with subclinical cardiac damage and long-term cardiovascular risk.

“The benefits of healthy eating are swift and direct. High sodium is not just about taste, it causes heart strain,” Stephen Juraschek, MD, PhD, from Beth Israel Deaconess Medical Center, Boston, said in an interview.

“We should consciously follow a diet enriched with fruit and vegetables and low in sodium. Collectively, we should think about how foods are promoted in society and what is an acceptable amount of sodium for food supplies,” said Dr. Juraschek.

The findings, from a secondary analysis of the DASH-Sodium trial, were published the Journal of the American College of Cardiology.
 

Renewed focus on diet

“These data should spur a renewed focus on the critical need for widespread adoption of the DASH–low-sodium diet in the United States,” wrote the coauthors of a linked editorial.

“The challenge remains moving the DASH–low-sodium diet from the research world into the real world, where its significant health benefits can be fully realized,” they added.

The researchers evaluated the impact of the DASH diet and sodium restriction, individually and combined, on biomarkers of cardiac injury (high-sensitivity cardiac troponin I [hs-cTnI]), cardiac strain (N-terminal of the prohormone brain natriuretic peptide [NT-proBNP]), and inflammation (high-sensitivity C-reactive protein [hs-CRP]).

The DASH-Sodium trial was a controlled feeding study that enrolled 412 adults (mean age, 48 years; 56% women, 56% Black) with untreated systolic blood pressure between 120 and 159 mm Hg and diastolic blood pressure between 80 and 95 mm Hg. Mean baseline BP was 135/86 mm Hg.

Participants were randomly allocated to a typical American diet (control) or the heart-healthy DASH diet. Further, participants in both groups were assigned to each of three sodium intake levels: low (0.5 mg/kcal), medium (1.1 mg/kcal) or high (1.6 mg/kcal) for 30 days using a crossover design with washout periods in between.
