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.

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.

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.

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.

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.

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.

“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.

When possible, diagnostic tests to determine the cause of a first stroke or transient ischemic attack (TIA) should be completed within 48 hours after symptom onset, the American Heart Association/American Stroke Association said in an updated clinical practice guideline.

“It is critically important to understand the best ways to prevent another stroke once someone has had a stroke or a TIA,” Dawn O. Kleindorfer, MD, chair of the guideline writing group, said in a news release.

“If we can pinpoint the cause of the first stroke or TIA, we can tailor strategies to prevent a second stroke,” said Dr. Kleindorfer, professor and chair, department of neurology, University of Michigan, Ann Arbor.

The updated guideline was published online May 24, 2021, in Stroke.

“The secondary prevention of stroke guideline is one of the ASA’s ‘flagship’ guidelines, last updated in 2014,” Dr. Kleindorfer said.

The update includes “a number of changes to the writing and formatting of this guideline to make it easier for professionals to understand and locate information more quickly, ultimately greatly improving patient care and preventing more strokes in our patients,” she noted.
 

Let pathogenic subtype guide prevention

For patients who have survived a stroke or TIA, management of vascular risk factors, particularly hypertension, diabetes, cholesterol/triglyceride levels, and smoking cessation, are key secondary prevention tactics, the guideline said.

Limiting salt intake and/or following a heart-healthy Mediterranean diet is also advised, as is engaging in at least moderate-intensity aerobic activity for at least 10 minutes four times a week or vigorous-intensity aerobic activity for at least 20 minutes twice a week.

“Approximately 80% of strokes can be prevented by controlling blood pressure, eating a healthy diet, engaging in regular physical activity, not smoking and maintaining a healthy weight,” Amytis Towfighi, MD, vice chair of the guideline writing group and director of neurologic services, Los Angeles County Department of Health Services, noted in the release.

For health care professionals, the guideline said specific recommendations for secondary prevention often depend on the ischemic stroke/TIA subtype. “Therefore, new in this guideline is a section describing recommendations for the diagnostic workup after ischemic stroke, to define ischemic stroke pathogenesis (when possible), and to identify targets for treatment to reduce the risk of recurrent ischemic stroke. Recommendations are now segregated by pathogenetic subtype,” the guideline stated.

Among the recommendations:

• Use multidisciplinary care teams to personalize care for patients and employ shared decision-making with the patient to develop care plans that incorporate a patient’s wishes, goals, and concerns.
• Screen for  and initiate anticoagulant drug therapy to reduce recurrent events.
• Prescribe antithrombotic therapy, including antiplatelets or anticoagulants, in the absence of contraindications. The guideline noted that the combination of antiplatelets and anticoagulation is typically not recommended for preventing second strokes and that dual antiplatelet therapy (DAPT) – taking  along with a second medication to prevent blood clotting – is recommended in the short term and only for specific patients: those with early arriving minor stroke and high-risk TIA or severe symptomatic stenosis.
• Consider  or carotid artery stenting for select patients with narrowing of carotid arteries.
• Aggressive medical management of risk factors and short-term DAPT are preferred for patients with severe intracranial stenosis thought to be the cause of first stroke or TIA.
• In some patients, it’s reasonable to consider percutaneous closure of .

The guideline is accompanied by a systematic review and meta-analysis regarding the benefits and risks of dual antiplatelet versus single antiplatelet therapy for secondary stroke prevention. The authors conclude that DAPT may be appropriate for select patients.

“Additional research is needed to determine: the optimal timing of starting treatment relative to the clinical event; the optimal duration of DAPT to maximize the risk-benefit ratio; whether additional populations excluded from POINT and CHANCE [two of the trials examined], such as those with major stroke, may also benefit from early DAPT; and whether certain genetic profiles eliminate the benefit of early DAPT,” concluded the reviewers, led by Devin Brown, MD, University of Michigan.

The guideline was prepared on behalf of and approved by the AHA Stroke Council’s Scientific Statements Oversight Committee on Clinical Practice Guidelines. The writing group included representatives from the AHA/ASA and the American Academy of Neurology. The guideline has been endorsed by the American Association of Neurological Surgeons/Congress of Neurological Surgeons and the Society of Vascular and Interventional Neurology. It has also been affirmed by the AAN as an educational tool for neurologists.

The research had no commercial funding.

The benefits of COVID-19 vaccination “enormously outweigh” the rare possible risk for heart-related complications, including myocarditis, the American Heart Association/American Stroke Association (ASA) says in new statement.

The message follows a Centers for Disease Control and Prevention report that the agency is monitoring the Vaccine Adverse Events Reporting System (VAERS) and the Vaccine Safety Datalink (VSD) for cases of myocarditis that have been associated with the mRNA vaccines against SARS-CoV-2 from Pfizer and Moderna.

The “relatively few” reported cases myocarditis in adolescents or young adults have involved males more often than females, more often followed the second dose rather than the first, and were usually seen in the 4 days after vaccination, the CDC’s COVID-19 Vaccine Safety Technical Work Group (VaST) found.

“Most cases appear to be mild, and follow-up of cases is ongoing,” the CDC says. “Within CDC safety monitoring systems, rates of myocarditis reports in the window following COVID-19 vaccination have not differed from expected baseline rates.”

In their statement, the AHA/ASA “strongly urge” all adults and children 12 years and older to receive a COVID-19 vaccine as soon as possible.

“The evidence continues to indicate that the COVID-19 vaccines are nearly 100% effective at preventing death and hospitalization due to COVID-19 infection,” the groups say.

Although the investigation of cases of myocarditis related to COVID-19 vaccination is ongoing, the AHA/ASA notes that myocarditis is typically the result of an actual viral infection, “and it is yet to be determined if these cases have any correlation to receiving a COVID-19 vaccine.”

“We’ve lost hundreds of children, and there have been thousands who have been hospitalized, thousands who developed an inflammatory syndrome, and one of the pieces of that can be myocarditis,” Richard Besser, MD, president and CEO of the Robert Wood Johnson Foundation (RWJF), said today on ABC’s Good Morning America.

Still, “from my perspective, the risk of COVID is so much greater than any theoretical risk from the vaccine,” said Dr. Besser, former acting director of the CDC.

The symptoms that can occur after COVID-19 vaccination include tiredness, headache, muscle pain, chills, fever, and nausea, reminds the AHA/ASA statement. Such symptoms would “typically appear within 24-48 hours and usually pass within 36-48 hours after receiving the vaccine.”

All health care providers should be aware of the “very rare” adverse events that could be related to a COVID-19 vaccine, including myocarditis, blood clots, low platelets, and symptoms of severe inflammation, it says.

“Health care professionals should strongly consider inquiring about the timing of any recent COVID vaccination among patients presenting with these conditions, as needed, in order to provide appropriate treatment quickly,” the statement advises.

The greatest relative benefit from omecamtiv mecarbil, a member of the novel myotropic drug class that improves cardiac performance, is produced in heart failure patients with the lowest left ventricular ejection fraction (LVEF), a new analysis of the recently published phase 3 GALACTIC-HF trial has found.

The findings reinforce the potential for this drug to be helpful in the management of the most advanced stages of heart failure with reduced ejection fraction (HFrEF), reported John R. Teerlink, MD, director of heart failure at San Francisco Veterans Affairs Medical Center, at the annual scientific sessions of the American College of Cardiology.

The phase 3 multinational GALACTIC-HF trial, published earlier this year, linked omecamtiv mecarbil with an 8% reduction in the risk of a heart failure–related events or cardiovascular death, relative to placebo, which was the primary outcome. For entry, HFrEF patients were required to have a LVEF of 35% or less.

Drilling down on ejection fraction

The new analysis divided participants into quartiles of baseline LVEF and then compared relative outcomes and safety.

In the lowest quartile, defined by a LVEF of 22% or lower, the reduction in risk of events reached 17% (hazard ratio, 0.83; 95% confidence interval, 0.73-0.95) for omecamtiv mecarbil relative to placebo. In the highest, defined by a LVEF of 33% or greater, the benefit fell short of significance (HR 0.99; 95% CI, 0.84-1.16). Across quartiles, LVEF was the “strongest modifier of the treatment effect,” emerging in this analysis as a statistically significant (P = .004) continuous variable.

The comparison by LVEF quartiles also provided an opportunity to show that omecamtiv mecarbil was as safe and well tolerated in those with the most advanced disease as in those less sick. At the lowest levels of LVEF, like the higher levels, omecamtiv mecarbil did not produce any adverse effects on blood pressure, heart rate, potassium homeostasis, or renal function.

In GALACTIC-HF, 8,256 HFrEF patients with LVEF 35% or less were randomized to omecamtiv mecarbil or placebo. The primary composite outcome of hospitalization or urgent visit for heart failure or death from cardiovascular causes was evaluated after a median of 21.8 months on therapy.

When incidence rate per 100 patient years was graphed against the range of LVEF, the relative advantage of omecamtiv mecarbil became visible just below an LVEF of 30%, climbing steadily even to the lowest LVEF, which reached 10%.

Perhaps relevant to the reduction in events, there were also greater relative reductions in NT-proBNP (NT-proB-type natriuretic peptide) for omecamtiv mecarbil at lower relative to higher LVEF. Although omecamtiv mecarbil is not associated with any direct vascular, electrophysiologic, or neurohormonal effects, according to Dr. Teerlink, the indirect effects of selective binding to cardiac myosin has been associated with lower NT-proBNP and other biomarkers of cardiac remodeling in prior clinical studies.

Although Dr. Teerlink acknowledged that relatively few patients in GALACTIC-HF received an angiotensin-receptor neprilysin inhibitor (ARNI) or a sodium glucose cotransporter-2 (SGLT2) inhibitor, he said there is “every reason to believe that omecamtiv mecarbil would be complementary to these therapies.” He said the mechanism of action of omecamtiv mecarbil, which improves systolic function, has no overlap with these drugs.

Importantly, there is a particular need for new treatment options in patients with advanced LVEF, according to Dr. Teerlink, who cited evidence, for example, that “the beneficial effect of [the ARNI] sacubitril valsartan, while still significant, decreases in patients with LVEF less than 35%.”

Overall, based on these results, “we believe that omecamtiv mecarbil represents a novel therapy that holds the promise of improving clinical outcomes in patients with severely reduced ejection fraction, which are the very patients that are most challenging for us to treat,” Dr. Teerlink said.
 

Omecamtiv mecarbil may ‘buy you some time’

Ileana Piña, MD, clinical professor of medicine, Central Michigan University, Mount Pleasant, Mich., agreed. She said that omecamtiv mecarbil, if approved, will be an option for the type of HFrEF patients who are being considered for heart transplant or mechanical-assist devices.

“We are very loath to use inotropes in this population, because we know that ultimately the inotrope is not going to do well,” said Dr. Piña, calling these therapies a “Band-Aid.” Based on the evidence from GALACTIC-HF, she thinks that omecamtiv mecarbil will be more versatile.

“This drug does not increase myocardial oxygen demand as do the inotropes, and it can be given in the outpatient setting if need be, so I see this as a real advance,” Dr. Piña said. Although Dr. Piña acknowledged that omecamtiv mecarbil did not reduce mortality in the GALACTIC-HF trial, “at least it will buy you some time.”

Dr. Teerlink has financial relationships with multiple pharmaceutical companies, including Amgen, Cytogenetics, and Servier, which provided funding for the GALACTIC-HF trial. Dr. Piña reports no potential conflicts of interest.
