First SGLT1/2 inhibitor shows ‘spectacular’ phase 3 safety and efficacy in T2D
Sotagliflozin, a novel type of sodium-glucose cotransporter inhibitor, showed the diverse benefits this drug class provides along some new twists in a pair of international pivotal trials that together enrolled nearly 12,000 patients with type 2 diabetes.
Unprecedented benefits were seen for the first time with a drug, sotagliflozin (Zynquista) that produces both sodium-glucose cotransporter 2 inhibition as well as SGLT1 inhibition.
They included a big reduction in both MIs and strokes; an ability to meaningfully reduce hyperglycemia in patients with severe renal dysfunction with an estimated glomerular filtration rate (eGFR) of 25-29 mL/min per 1.73 m2; an ability to safely and effectively start in patients still hospitalized (but stable) for an acute heart failure episode; and a striking 37% relative risk reduction in cardiovascular death, heart failure hospitalizations, or an urgent outpatient visit for heart failure in 739 of the patients enrolled in both trials who had heart failure with preserved ejection fraction (HFpEF).
These studies produced for the first time evidence from controlled, prospective, randomized trials that a drug could improve the outcome of HFpEF patients.
All these novel outcomes came on top of the usual benefits clinicians have generally seen across the SGLT2 inhibitors already on the U.S. market: reductions in cardiovascular death and heart failure hospitalizations among all patients with type 2 diabetes, preservation of renal function, and hemoglobin A1c lowering among T2D patients with eGFR levels of at least 30 mL/min per 1.73 m2.
“The data look spectacular,” summed up Deepak L. Bhatt, MD, who presented the results from the two trials, SOLOIST-WHF and SCORED, in talks at the virtual scientific sessions of the American Heart Association.
“I think sotagliflozin has the potential to be the best in class” based on the several added attributes shown in the two trials, he said in an interview. “We’ve shown that it is very safe, well tolerated, and effective.”
The primary results were a significant 33% relative risk reduction with sotagliflozin treatment, compared with placebo in the rate of total cardiovascular deaths, hospitalizations for heart failure, or urgent outpatient visits for heart failure during just over 9 months of median follow-up among patients with T2D recently hospitalized for heart failure in SOLOIST-WFH. And a significant 26% relative risk reduction with sotagliflozin for the same endpoint after a median follow-up of just over 14 months in SCORED, which enrolled patients with T2D and chronic kidney disease.
“Sotagliflozin adds to the SGLT2 inhibitor story,” and the SOLOIST-WHF results “may shift our focus to vulnerable, acute heart failure patients with an opportunity to treat during the transition phase,” when these patients leave the hospital, commented Jane E. Wilcox, MD, the study’s designated discussant and a heart failure cardiologist at Northwestern Medicine in Chicago.
A dual SGLT inhibitor
What sets sotagliflozin apart from the SGLT2 inhibitors is that it not only inhibits that protein but also SGTL1, which primarily resides in the gastrointestinal tract and is the main route for gut absorption of glucose. Dr. Bhatt said that he was unaware of any other SGLT1/2 inhibitors currently in advanced clinical testing.
The activity of sotagliflozin against the SGLT1 protein likely explains its ability to cut A1c levels in patients with severe renal dysfunction, a condition that stymies glucose lowering by SGLT2 inhibitors. In SCORED, which randomized 10,584 patients with T2D at 750 study sites in 44 countries, 813 patients (8%) had an eGFR of 25-29 mL/min per 1.73 m2 at enrollment. Sotagliflozin treatment led to an average 0.6% cut in A1c in this subgroup, and by the same average amount among the patients with GFRs of 30-60 mL/min per 1.73 m2.
“This is a huge finding for endocrinologists and primary care physicians” who treat patients with T2D who have severe renal dysfunction, said Dr. Bhatt, a professor of medicine at Harvard Medical School in Boston. “It’s a good enough reason by itself to approve this drug.”
The same mechanism may also be behind another unexpected finding in SCORED. Treatment with sotagliflozin cut the rate of total episodes of cardiovascular death, nonfatal MI, or nonfatal stroke by an absolute 1.6%, compared with placebo, and by a relative 23%. This benefit was largely driven by a 32% relative risk reduction total in MIs, and a 34% relative risk reduction in total stroke, both significant differences.
“No SGLT2 inhibitor has shown a reduction in stroke, and the MI signals have been mixed. The sizable MI and stroke effects are unique to sotagliflozin,” compared with the SGLT2 inhibitors, and likely reflect one or more mechanisms that result from blocked gut SGLT1 and a cut in GI glucose uptake, said Dr. Bhatt. “Probably some novel mechanism we don’t fully understand.”
First-ever HFpEF benefit
In contrast to these two benefits that are probably unique to drugs that inhibit the SGLT1 protein, sotagliflozin showed two other notable and unprecedented benefits that are likely generalizable to the SGLT2 inhibitors.
First is the striking benefit for HFpEF. Neither SOLOIST, which enrolled 1,222 patients with T2D and just hospitalized for worsening heart failure, nor SCORED, which enrolled patients with T2D and chronic kidney disease based exclusively on an eGFR of 25-60 mL/min per 1.73 m2, excluded patients with HFpEF, defined as heart failure patients with a left ventricular ejection fraction of at least 50%. The two studies together included a total of 739 of these patients, and they split fairly evenly between treatment with sotagliflozin or placebo.
The combined analysis showed that the incidence rate for the primary endpoint in both SOLOIST and SCORED was 59% with placebo and 39% with sotagliflozin, an absolute event reduction of 11.6 events/100 patient-years, and a significant 37% relative risk reduction, with a number needed to treat to prevent 1 event per year event of 9.
Although this observation comes from a nonprespecified combined analysis, “to me this result seems real, and I think it’s a class effect that I’m willing to extrapolate to the SGLT2 inhibitors,” Dr. Bhatt said. “It will change my practice,” he added, by spurring him to more aggressively prescribe an SGLT2 inhibitor to a patient with T2D and HFpEF.
“I think there has been some hesitation to use SGLT2 inhibitors in T2D patients with HFpEF” because of the paucity of data in this population, even though labeling and society recommendations do not rule it out. “I hope this finding will move that needle, and also generally improve SGLT2 inhibitor uptake, which has been low,” he said.
Also safe soon after acute heart failure decompensation
The other finding likely generalizable to SGLT2 inhibitors stems from the design of SOLOIST-WHF, which tested the efficacy and safety of starting sotagliflozin in patients with T2D as soon as they were stable after hospitalization for acute heart failure decompensation.
“Showing safety and efficacy when started in the hospital is pretty meaningful, because its tells patients that this drug is important and they should stay on it,” which should improve adherence, predicted Dr. Bhatt, who is also executive director of Interventional Cardiovascular Programs at Brigham and Women’s Hospital in Boston. “That’s the ultimate treatment path to prevent patients from falling through the cracks” and failing to receive an SGLT2 inhibitor.
SOLOIST-WHF enrolled patients hospitalized for worsening heart failure who also required intravenous diuretic treatment but had become stable enough to transition to an oral diuretic and come off oxygen. During a median follow-up of just over 9 months (both SOLOIST-WHF and SCORED ended sooner than planned because of a change in drug company sponsorship), treatment with sotagliflozin cut the primary endpoint by a relative 33%, compared with placebo, and with an absolute reduction of 25 events per 100 patient-years for a number needed to treat of 4. Sotagliflozin produced a strikingly high level of treatment efficiency driven by the high event rate in these recently decompensated patients. The benefit also appeared quickly, with a significant cut in events discernible within 28 days.
Extrapolating this finding to the SGLT2 inhibitors is “not a huge leap of faith,” Dr. Bhatt said.
“There is a role for sotagliflozin in acute heart failure. It showed benefit in these high-risk, transition-phase patients,” said Dr. Wilcox.
Simultaneously with Dr. Bhatt’s presentation, results of SOLOIST-WHF and SCORED were published online in the New England Journal of Medicine.
The trials were sponsored initially by Sanofi, and more recently by Lexicon. Dr. Bhatt has received research funding from both companies, and also from several other companies. He also is an adviser to several companies. Dr. Wilcox has been a consultant to Boehringer Ingelheim and Medtronic.

FROM AHA 2020
Empagliflozin favorably reshaped left ventricles in HFrEF patients
Treatment with the SGLT2 inhibitor empagliflozin led to significant reductions in both left ventricular end systolic and diastolic volumes in two independent randomized studies of patients with heart failure with reduced ejection fraction.
These results provide important new evidence that one way a drug from this class exerts its beneficial effects on cardiovascular outcomes in these patients is by producing favorable left-ventricular remodeling.
One of the two studies involved only patients with heart failure with reduced ejection fraction (HFrEF) with diabetes and examined treatment impact after 36 weeks. The second study focused exclusively on HFrEF patients without diabetes and followed patients for 6 months. Both studies also generated additional significant evidence of favorable left-ventricular effects.
“The results of these two new trials are incredibly important, as they tell cardiologists one of the mechanisms by which SGLT2 [sodium glucose co-transporter 2] inhibitors reduce heart failure hospitalizations and cardiovascular death,” said Mark C. Petrie, MBChB, professor at the Institute of Cardiovascular & Medical Sciences at the University of Glasgow, and principal investigator for one of the two studies.
“Many cardiologists want to know mechanisms as well as clinical benefit. These remodeling data showing that these drugs reduce the size of abnormally large hearts [and] are also very important for patients,” Dr. Petrie said in an interview. “There have been more than 50 publications on potential mechanisms of benefit of SGLT2 inhibitors in HFrEF, but these are the first randomized, mechanistic data.”
Mechanistic clues follow large cardiovascular outcome trials
Results from a large randomized trial, EMPEROR-Reduced, recently showed that treatment with empagliflozin (Jardiance) on top of standard HFrEF treatment led to significant benefits in patients with or without type 2 diabetes (T2D), compared with placebo, for major cardiovascular and renal endpoints, including the combination of cardiovascular death or hospitalization for heart failure. And results from a second large randomized trial, DAPA-HF, showed similar results with a different drug from the same class, dapagliflozin (Farxiga), in an earlier report.
But while these reports led to quick uptake of these two drugs for the treatment of patients with HFrEF, the means by which these agents exert their HFrEF benefits have been unclear.
“Our study identifies why this drug [empagliflozin] is effective – because it improves heart function, something that has not been understood until now,” Carlos G. Santos-Gallego, MD, lead investigator for the second new report, said in a written statement. “Many doctors are afraid of prescribing a drug they do not understand, and our findings will help clinicians feel more comfortable giving this to patients once approved.”
On the strength of the DAPA-HF results, dapagliflozin received a revised U.S. label in May 2020 that added the indication for treating patients with HFrEF regardless of the whether patients also have T2D, the original indication for prescribing the drug. Many experts anticipate that a similar addition to the label for empagliflozin will soon occur.
EMPA-TROPISM examines patients with no T2D
The single-center study reported by Dr. Santos-Gallego randomized 84 patients with HFrEF and no diabetes to standard treatment with empagliflozin or placebo and measured several parameters in 80 patients who completed the planned 6 months of treatment. The primary endpoints were the changes in both left ventricular end systolic and diastolic volume from baseline in the empagliflozin-treated patients compared with patients on placebo, measured by cardiac MR.
The results showed an average reduction of end systolic volume of 26.6 mL from baseline compared with a small rise in the placebo patients, and an average drop in end diastolic volume of 25.1 mL from baseline compared again with a small increase in the controls. Both differences were statistically significant, reported the senior author of the study, Juan J. Badimon, PhD, in a talk at the virtual scientific sessions of the American Heart Association. Concurrently, the results were published online in the Journal of the American College of Cardiology.
Results from the EMPA-TROPISM study also showed several other significant benefits from empagliflozin treatment, both to left ventricular shape and function as well as to other measures of patient well being. The drug regimen led to an increase in left ventricular ejection fraction, a decrease in left ventricular mass, reduced myocardial fibrosis and aortic stiffness, increased peak oxygen consumption, an increased distance traveled in a 6-minute walk test, and improved quality of life, said Dr. Badimon, professor of medicine and director of the Atherothrombosis Research Unit at the Cardiovascular Institute at the Icahn School of Medicine at Mount Sinai in New York.
SUGAR-DM-HF enrolled only T2D patients
The second study, SUGAR-DM-HF, randomized 105 patients with HFrEF and T2D to treatment with empagliflozin or placebo at any of 15 centers in Scotland, with 92 patients completing the full 36 weeks on treatment. One of the study’s two primary endpoints was the change in left ventricular end systolic volume index, which dropped by an average of 7.9 mL/m2 in patients who received empagliflozin and by 1.5 mL/m2 in the controls, a significant average between-group difference of 6.0 mL/m2, reported Matthew M.Y. Lee, MBChB, at the same meeting.
However, the second primary endpoint, change in left ventricular global longitudinal strain, showed no significant difference in effect on empagliflozin compared with placebo, said Dr. Lee, a cardiologist at the University of Glasgow. Concurrently with his report the results appeared in an article published online in Circulation.
The results also showed a significant drop in left ventricular end diastolic volume index from baseline compared with the control patients, with an average between-group difference in the reduction from baseline of 8.2 mL/m2.
“Reverse cardiac remodeling is a mechanism by which SGLT2 inhibitors reduce heart failure hospitalizations and cardiovascular mortality,” Dr. Lee concluded during his presentation at the meeting.
Although the findings from both studies together provide strong evidence for an effect by empagliflozin on left ventricular shape and function, neither study provides much insight into how this drug exerts these effects. The authors of both studies agreed on several potential explanations, including reductions in cardiac preload and afterload that could reduce left ventricular stretch and volume; a change triggered in myocardial energetics that switches from a metabolism mostly dependent on glucose to one more geared to using fatty acids, ketone bodies, and branched chain amino acids; and a possible drug-induced reduction in oxidative stress and inflammation.
SUGAR-DM-HF was sponsored by a grant from Boehringer Ingelheim, the company that along with Eli Lilly markets empagliflozin (Jardiance). Dr. Lee had no disclosures. Dr. Petrie has been a consultant to Boehringer Ingelheim and Eli Lilly and to several other companies. EMPA-TROPISM was sponsored by a grant from Boehringer Ingelheim. Dr. Badimon and Dr. Santos-Gallego had no disclosures.
Treatment with the SGLT2 inhibitor empagliflozin led to significant reductions in both left ventricular end systolic and diastolic volumes in two independent randomized studies of patients with heart failure with reduced ejection fraction.

These remodeling data showing that these drugs reduce the size of abnormally large hearts [and] are also very important for patients,” Dr. Petrie said in an interview. “There have been more than 50 publications on potential mechanisms of benefit of SGLT2 inhibitors in HFrEF, but these are the first randomized, mechanistic data.”
Mechanistic clues follow large cardiovascular outcome trials
Results from a large randomized trial, EMPEROR-Reduced, recently showed that treatment with empagliflozin (Jardiance) on top of standard HFrEF treatment led to significant benefits in patients with or without type 2 diabetes (T2D), compared with placebo, for major cardiovascular and renal endpoints, including the combination of cardiovascular death or hospitalization for heart failure. And results from a second large randomized trial, DAPA-HF, showed similar results with a different drug from the same class, dapagliflozin (Farxiga), in an earlier report.
But while these reports led to quick uptake of these two drugs for the treatment of patients with HFrEF, the means by which these agents exert their HFrEF benefits have been unclear.
“Our study identifies why this drug [empagliflozin] is effective – because it improves heart function, something that has not been understood until now,” Carlos G. Santos-Gallego, MD, lead investigator for the second new report, said in a written statement. “Many doctors are afraid of prescribing a drug they do not understand, and our findings will help clinicians feel more comfortable giving this to patients once approved.”
On the strength of the DAPA-HF results, dapagliflozin received a revised U.S. label in May 2020 that added the indication for treating patients with HFrEF regardless of the whether patients also have T2D, the original indication for prescribing the drug. Many experts anticipate that a similar addition to the label for empagliflozin will soon occur.
EMPA-TROPISM examines patients with no T2D
The single-center study reported by Dr. Santos-Gallego randomized 84 patients with HFrEF and no diabetes to standard treatment with empagliflozin or placebo and measured several parameters in 80 patients who completed the planned 6 months of treatment. The primary endpoints were the changes in both left ventricular end systolic and diastolic volume from baseline in the empagliflozin-treated patients compared with patients on placebo, measured by cardiac MR.
The results showed an average reduction of end systolic volume of 26.6 mL from baseline compared with a small rise in the placebo patients, and an average drop in end diastolic volume of 25.1 mL from baseline compared again with a small increase in the controls. Both differences were statistically significant, reported the senior author of the study, Juan J. Badimon, PhD, in a talk at the virtual scientific sessions of the American Heart Association. Concurrently, the results were published online in the Journal of the American College of Cardiology.
Results from the EMPA-TROPISM study also showed several other significant benefits from empagliflozin treatment, both to left ventricular shape and function as well as to other measures of patient well being. The drug regimen led to an increase in left ventricular ejection fraction, a decrease in left ventricular mass, reduced myocardial fibrosis and aortic stiffness, increased peak oxygen consumption, an increased distance traveled in a 6-minute walk test, and improved quality of life, said Dr. Badimon, professor of medicine and director of the Atherothrombosis Research Unit at the Cardiovascular Institute at the Icahn School of Medicine at Mount Sinai in New York.
SUGAR-DM-HF enrolled only T2D patients
The second study, SUGAR-DM-HF, randomized 105 patients with HFrEF and T2D to treatment with empagliflozin or placebo at any of 15 centers in Scotland, with 92 patients completing the full 36 weeks on treatment. One of the study’s two primary endpoints was the change in left ventricular end systolic volume index, which dropped by an average of 7.9 mL/m2 in patients who received empagliflozin and by 1.5 mL/m2 in the controls, a significant average between-group difference of 6.0 mL/m2, reported Matthew M.Y. Lee, MBChB, at the same meeting.
However, the second primary endpoint, change in left ventricular global longitudinal strain, showed no significant difference in effect on empagliflozin compared with placebo, said Dr. Lee, a cardiologist at the University of Glasgow. Concurrently with his report the results appeared in an article published online in Circulation.
The results also showed a significant drop in left ventricular end diastolic volume index from baseline compared with the control patients, with an average between-group difference in the reduction from baseline of 8.2 mL/m2.
“Reverse cardiac remodeling is a mechanism by which SGLT2 inhibitors reduce heart failure hospitalizations and cardiovascular mortality,” Dr. Lee concluded during his presentation at the meeting.
Although the findings from both studies together provide strong evidence for an effect by empagliflozin on left ventricular shape and function, neither study provides much insight into how this drug exerts these effects. The authors of both studies agreed on several potential explanations, including reductions in cardiac preload and afterload that could reduce left ventricular stretch and volume; a change triggered in myocardial energetics that switches from a metabolism mostly dependent on glucose to one more geared to using fatty acids, ketone bodies, and branched chain amino acids; and a possible drug-induced reduction in oxidative stress and inflammation.
SUGAR-DM-HF was sponsored by a grant from Boehringer Ingelheim, the company that along with Eli Lilly markets empagliflozin (Jardiance). Dr. Lee had no disclosures. Dr. Petrie has been a consultant to Boehringer Ingelheim and Eli Lilly and to several other companies. EMPA-TROPISM was sponsored by a grant from Boehringer Ingelheim. Dr. Badimon and Dr. Santos-Gallego had no disclosures.
Treatment with the SGLT2 inhibitor empagliflozin led to significant reductions in both left ventricular end systolic and diastolic volumes in two independent randomized studies of patients with heart failure with reduced ejection fraction.
These results provide important new evidence that one way a drug from this class exerts its beneficial effects on cardiovascular outcomes in these patients is by producing favorable left-ventricular remodeling.
One of the two studies involved only patients with heart failure with reduced ejection fraction (HFrEF) with diabetes and examined treatment impact after 36 weeks. The second study focused exclusively on HFrEF patients without diabetes and followed patients for 6 months. Both studies also generated additional significant evidence of favorable left-ventricular effects.
“The results of these two new trials are incredibly important, as they tell cardiologists one of the mechanisms by which SGLT2 [sodium glucose co-transporter 2] inhibitors reduce heart failure hospitalizations and cardiovascular death,” said Mark C. Petrie, MBChB, professor at the Institute of Cardiovascular & Medical Sciences at the University of Glasgow, and principal investigator for one of the two studies.

Intravenous iron reduces HF readmissions: AFFIRM-AHF
Iron supplementation reduces heart failure (HF) readmissions in iron-deficient patients hospitalized for acute HF, according to results of the AFFIRM-AHF trial.
After 52 weeks, intravenous ferric carboxymaltose (Ferinject) reduced the risk of total HF hospitalizations and cardiovascular (CV) death by 21% compared with placebo (293 vs 372 events; rate ratio [RR] 0.79; 95% CI, 0.62 - 1.01).
Although the composite primary endpoint failed to achieve statistical significance, it was driven by a significant 26% reduction in the risk of total HF hospital readmissions (P = .013) without an effect on CV mortality (P =.809).
Because the management and follow-up of patients was affected by the COVID-19 pandemic, a prespecified sensitivity analysis was performed that censored patients in each country at the date when its first COVID-19 patient was reported, explained principal investigator Piotr Ponikowski, MD, PhD, Wroclaw Medical University, Wroclaw, Poland.
That analysis revealed a significant 30% reduction in total HF readmissions (P = .005) in patients receiving ferric carboxymaltose (FCM), as well as significant benefits on the primary composite and secondary endpoints.
Notably, 80% of patients required only one or two injections and HF hospitalizations were reduced irrespective of anemia status.
“Iron deficiency should be searched in patients hospitalized with acute heart failure — assessed using a simple blood test — and is now an important therapeutic target,” Ponikowski said at the virtual American Heart Association (AHA) Scientific Sessions 2020.
The results were also published simultaneously in The Lancet.
Iron deficiency is present in up to 70% of patients with acute HF and a predictor of poor outcome, independent of anemia and ejection fraction, he noted.
The FAIR-HF, CONFIRM-HF, and EFFECT-HF trials demonstrated that IV iron supplementation improves exercise capacity, symptoms, and quality of life in iron-deficient HF patients.
However, no such benefit was seen with oral IV in the IRONOUT trial. “So it seems if we are to replace iron, it needs to be done using intravenous therapy,” said John McMurray, MD, University of Glasgow, Scotland, who was invited to discuss the results.
He observed that the reduction in HF hospitalizations in AFFIRM-AHF were relatively modest and that the trial was never expected to show a benefit on CV mortality. Also, the COVID-19 sensitivity analysis providing more convincing effects is a valid approach and one recommended by regulators.
Further, the findings are supported by independent evidence in chronic kidney disease, from the PIVOTAL trial, that intravenous iron reduces HF hospitalizations, McMurray said.
“The million-dollar question, of course, is what will the results of this study mean for the guidelines: I think they probably will change the guidelines,” he said. “Certainly, I hope they will change the US guidelines, which have really given a very lukewarm recommendation for intravenous iron and I think that should probably be stronger.”
In a class IIb recommendation, the 2017 American College of Cardiology/AHA/Heart Failure Society of America heart failure guidelines say intravenous iron “might be reasonable” to improve functional status and quality of life in New York Heart Association class II and III patients with iron deficiency.
The 2016 European Society of Cardiology guidelines include a class IIa recommendation that IV iron “should be considered” in iron-deficient patients with symptomatic HF with reduced ejection fraction.
“This is the first large-scale [trial] of IV supplementation that could potentially change the way we approach patients, particularly those with hospitalized heart failure,” past AHA president Clyde Yancy, MD, MSc, Northwestern University Feinberg School of Medicine in Chicago, said during an earlier press briefing.
He pointed out that clinicians have been circumspect about the early IV iron data. “I have to congratulate you because you’ve changed the narrative,” Yancy said. “We have to start thinking about iron deficiency; we have to think about how we incorporate this in treatment protocols.”
Press briefing panelist Marc Pfeffer, MD, PhD, Brigham and Women’s Hospital and Harvard Medical School in Boston, acknowledged he was among those circumspect.
“I’m no longer a skeptic and I want to congratulate them for showing it’s a risk factor,” he said. “It’s one thing to have a risk factor; it’s another to be a modifiable risk factor and I think that’s what’s so exciting about this.”
The double-blind, phase 4 AFFIRM-AHF trial randomly assigned 1132 patients to receive a bolus injection of ferric carboxymaltose or normal saline before hospital discharge for an acute HF episode. Subsequent treatment was given, as needed, up to 24 weeks post-randomization.
At admission, all patients had left ventricular ejection fractions less than 50% and iron deficiency (serum ferritin <100 ng/mL or serum ferritin 100-299 ng/mL if transferrin saturation <20%).
The modified intention-to-treat (mITT) analysis included 558 FCM patients and 550 controls in whom study treatment was started and for whom at least one post-randomization value was available.
Press briefing discussant Nancy Sweitzer, MD, PhD, director of the University of Arizona’s Sarver Heart Center in Tucson, said AFFIRM-AHF is an “important trial likely to change guidelines” and “targeted one of the highest risk populations we have in heart failure.”
Patients with iron deficiency tend to be elderly with more comorbidities, have longer hospital lengths of stay, and higher readmission rates. “So impacting hospitalizations in this population is incredibly impactful,” she said.
“Awareness and assessment of iron deficiency are an important part of inpatient care of patients with ejection fractions less than or equal to 50% and acute decompensated heart failure, and I think all of us in the community need to pay much more attention to this issue.”
As with any new therapy, there are implementation challenges such as how to monitor patients and deliver the therapy in a cost-effective way, Sweitzer said.
The trial focused on the most vulnerable period for HF patients, but these patients should be rechecked every 3 to 4 months for iron deficiency, Ponikowski observed during the briefing.
“This is a modifiable risk factor,” he said. “We only need to remember, we only need to assess it, and we have a very, very simple tool in our hands. We just need to measure two biomarkers, transferrin saturation and ferritin — that’s all.”
Unanswered questions include the mechanism behind the reduction in hospitalization, the relationship of benefit to hemoglobin levels, and whether there is a differential benefit based on age, presence of ischemia, or sex, especially as women tend to be more severely affected by iron deficiency, Sweitzer said.
During the formal presentation, Ponikowski said the primary endpoint was consistent in subgroup analyses across baseline hemoglobin, estimated glomerular filtration rate, and N-terminal pro-brain natriuretic peptide levels, HF etiology, ejection fraction, and whether HF was diagnosed prior to the index hospitalization.
Treatment with FCM was safe, with no significant differences between the FCM and placebo groups in serious adverse events (45% vs 51%) or adverse events leading to study discontinuation (18% vs 17%), he reported. The most common adverse events were cardiac disorders (40.1% vs 44.3%) and infections (18.2% vs 22%).
AFFIRM-AHF is the first of three ongoing mortality and morbidity trials in heart failure with intravenous ferric carboxymaltose; the others are FAIR-HF2 and HEART-FID. Additional insights are also expected next year on intravenous iron isomaltoside from the Scottish-based IRONMAN trial in 1300 HF patients with iron deficiency.
The study was sponsored by Vifor International. Ponikowski has received research grants and personal fees from Vifor Pharma; and personal fees from Amgen, Bayer, Novartis, Abbott Vascular, Boehringer Ingelheim, Merck, Pfizer, Servier, AstraZeneca, Berlin Chemie, Cibiem, Renal Guard Solutions Bristol-Myers Squibb, and Impulse Dynamics.
Pfeffer reported honoraria from AstraZeneca, Corvidia, GlaxoSmithKline, Jazz, MyoKardia, Novartis, Roche, Sanofi, and Servier; other relationships with DalCor and Novo Nordisk; research grants from Novartis; and an ownership interest in DalCor. Sweitzer reported research payments from Merck and Novartis; and consulting fees from Myocardia.
McMurray reported relationships with Amgen, AstraZeneca, Bayer, Boehringer Ingelheim, Cytokinetics, Novartis, and Servier. Yancy reported a relationship with Abbott and JAMA Network.

Press briefing discussant Nancy Sweitzer, MD, PhD, director of the University of Arizona’s Sarver Heart Center in Tucson, said AFFIRM-AHF is an “important trial likely to change guidelines” and “targeted one of the highest risk populations we have in heart failure.”
Patients with iron deficiency tend to be elderly with more comorbidities, have longer hospital lengths of stay, and higher readmission rates. “So impacting hospitalizations in this population is incredibly impactful,” she said.
“Awareness and assessment of iron deficiency are an important part of inpatient care of patients with ejection fractions less than or equal to 50% and acute decompensated heart failure, and I think all of us in the community need to pay much more attention to this issue.”
As with any new therapy, there are implementation challenges such as how to monitor patients and deliver the therapy in a cost-effective way, Sweitzer said.
The trial focused on the most vulnerable period for HF patients, but these patients should be rechecked every 3 to 4 months for iron deficiency, Ponikowski observed during the briefing.
“This is a modifiable risk factor,” he said. “We only need to remember, we only need to assess it, and we have a very, very simple tool in our hands. We just need to measure two biomarkers, transferrin saturation and ferritin — that’s all.”
Unanswered questions include the mechanism behind the reduction in hospitalization, the relationship of benefit to hemoglobin levels, and whether there is a differential benefit based on age, presence of ischemia, or sex, especially as women tend to be more severely affected by iron deficiency, Sweitzer said.
During the formal presentation, Ponikowski said the primary endpoint was consistent in subgroup analyses across baseline hemoglobin, estimated glomerular filtration rate, and N-terminal pro-brain natriuretic peptide levels, HF etiology, ejection fraction, and whether HF was diagnosed prior to the index hospitalization.
Treatment with FCM was safe, with no significant differences between the FCM and placebo groups in serious adverse events (45% vs 51%) or adverse events leading to study discontinuation (18% vs 17%), he reported. The most common adverse events were cardiac disorders (40.1% vs 44.3%) and infections (18.2% vs 22%).
AFFIRM-AHF is the first of three ongoing mortality and morbidity trials in heart failure with intravenous ferric carboxymaltose; the others are FAIR-HF2 and HEART-FID. Additional insights are also expected next year on intravenous iron isomaltoside from the Scottish-based IRONMAN trial in 1300 HF patients with iron deficiency.
The study was sponsored by Vifor International. Ponikowski has received research grants and personal fees from Vifor Pharma; and personal fees from Amgen, Bayer, Novartis, Abbott Vascular, Boehringer Ingelheim, Merck, Pfizer, Servier, AstraZeneca, Berlin Chemie, Cibiem, Renal Guard Solutions Bristol-Myers Squibb, and Impulse Dynamics.

TIPS-3: Polypill provides meaningful primary cardiovascular prevention
A once-daily polypill containing four drugs to lower blood pressure and LDL cholesterol reduced major adverse cardiovascular events by 21% relative to placebo in people at intermediate cardiovascular risk in the landmark TIPS-3 trial.
And with the addition of aspirin at 75 mg per day the combination achieved an even more robust 31% relative risk reduction, investigators reported at the.
“Aspirin contributes importantly to the benefits,” Salim Yusuf, MD, DPhil, emphasized in presenting the International Polycap Study (TIPS-3) results jointly with study coprincipal investigator Prem Pais, MD, at the virtual American Heart Association scientific sessions.
The multinational study provides powerful new support for a broad, population health–based approach to primary cardiovascular prevention.
“If half of eligible people [were to] use a polypill with aspirin, 3-5 million cardiovascular events per year would be avoided globally,” according to Dr. Yusuf, professor of medicine and director of the Population Health Research Institute at McMaster University in Hamilton, Ont.
“This is likely a cost-effective strategy to meet global targets of reducing cardiovascular disease by 30% by 2020,” added Dr. Pais of St. John’s Research Institute in Bangalore, India.
TIPS-3 included 5,713 participants at intermediate cardiovascular risk, with an estimated event risk of 1.8% per year using the INTERHEART Risk Score. Half were women. More than 80% of participants had hypertension, and nearly 40% had diabetes or impaired fasting glucose. Nearly 90% of participants came from India, the Philippines, Malaysia, Indonesia, or Bangladesh. All participants received advice about lifestyle management.
They were then randomized to receive a polypill or placebo, and then each group was further randomized to receive 75 mg/day of aspirin or matching placebo. The polypill contained 40 mg of simvastatin, 100 mg of atenolol, 25 mg of hydrochlorothiazide, and 10 mg of ramipril.
During a mean 4.6 years of follow-up, the primary composite major adverse cardiovascular event rate occurred in 4.4% of the polypill group, 4.1% of the polypill-plus-aspirin group, and 5.8% of the double-placebo group. This translated to a 21% reduction in cardiovascular disease with the polypill, a 31% reduction with polypill plus aspirin, and a 14% reduction in the composite of cardiovascular death, MI, or stroke with aspirin alone.
The polypill and placebo groups diverged in terms of the primary outcome starting about 6 months into the study, Dr. Pais noted.
Serious adverse events were less common with the polypill than with placebo. Importantly, there was no difference in major, minor, or GI bleeding between the polypill-plus-aspirin group and placebo-treated controls. Dr. Yusuf attributed the lack of excess bleeding in aspirin recipients to two factors: people with a history of bleeding or GI symptoms were excluded from TIPS-3, and the dose of aspirin used was lower than in other primary prevention trials, where bleeding offset the reduction in cardiovascular events.
Nonadherence was a major issue in TIPS-3, mainly because of delays in polypill production and distribution, coupled late in the trial with the COVID-19 pandemic. The nonadherence rate was 19% at 2 years, 32% at 4 years, and 43% at the study’s end. Only 5% of discontinuations were due to side effects. In a sensitivity analysis carried out in participants without discontinuation for nonmedical reasons, the benefits of the polypill plus aspirin were larger than in the overall study: a 39% relative risk reduction in the primary endpoint that probably offers a more accurate picture of the combination’s likely real-world performance.
Discussant Anushka Patel, MBBS, PhD, noted that TIPS-3 is the third randomized trial to provide direct evidence that a polypill-based strategy improves clinical outcomes. The effect sizes of the benefits – a 20%-30% reduction in major cardiovascular events – has been consistent in TIPS-3, PolyIran, and HOPE-3, each of which tested a different polypill drug combination.
“If implementation and adherence challenges can be addressed at the system, prescriber, and patient levels, and if high-quality polypills can be made affordable, the public health impact could actually be enormous,” said Dr. Patel, chief scientist at the George Institute for Global Health and professor of medicine at the University of New South Wales in Sydney, Australia.
However, she parted company with Dr. Yusuf regarding routine incorporation of aspirin into polypills.
“I think the totality of evidence would still probably favor taking an individualized approach that also considers bleeding risk,” the cardiologist said.
Donald Lloyd-Jones, MD, who chaired a press conference highlighting TIPS-3, declared, “You’re seeing a paradigm shift right here in front of your eyes today. This could be a game changer in terms of preventing large numbers of cardiovascular events.”
While TIPS-3 was conducted mainly in low- and middle-income countries, it’s important to recognize that’s where 75% of cardiovascular events and cardiovascular deaths now occur.
“This is very much a disease that has emerged in the developing world,” commented Dr. Lloyd-Jones, the AHA president-elect, chair of the AHA Council on Scientific Sessions Programming, and professor and chair of the department of preventive medicine at Northwestern University, Chicago.
He also sees a polypill strategy for primary cardiovascular prevention as highly viable in high-resource countries. It makes sense to employ it there initially in underserved communities, where a polypill-based approach sidesteps difficulties in monitoring care and adjusting medication doses due to reduced access to health care while minimizing cost and adherence issues, he added.
Dr. Yusuf and Dr. Pais reported receiving institutional research support from the TIPS-3 major sponsors: the Wellcome Trust, Cadila Pharmaceuticals, the Canadian Institutes of Health Research, and the Heart and Stroke Foundation of Canada.
Simultaneously with their presentation at AHA 2020, the TIPS-3 results were published online in the New England Journal of Medicine.

REPORTING FROM AHA 2020
GALACTIC-HF: New ‘myotropic’ drug class shows modest HFrEF benefit
Omecamtiv mecarbil, a member of the novel myotropic drug class that improves cardiac performance, safely produced a significant but modest improvement in heart failure events or cardiovascular death in a pivotal trial with HFrEF patients, leaving experts unsure about the role this drug could have on top of an already crowded list of four first-line drug classes for this condition.
“It remains to be investigated and discussed where omecamtiv mecarbil fits in” the overall approach to treating patients with heart failure with reduced ejection fraction (HFrEF), commented Paul Heidenreich, MD, designated discussant for the report at the virtual scientific sessions of the American Heart Association.
Omecamtiv mecarbil (OM) treatment produced a positive result for the study’s primary endpoint, with a 2.1% absolute cut in the combined rate of cardiovascular death, first heart failure hospitalization, or first urgent visit for heart failure compared with placebo during a median follow-up of about 22 months This represented an 8% relative risk reduction, reported John R. Teerlink, MD, at the meeting, and broke down as a 0.6% absolute drop in cardiovascular death compared with the placebo arm, a 0.7% cut in heart failure hospitalization, and a 0.8% drop in urgent outpatient visits for heart failure. Dr. Teerlink and his associates called this benefit “modest” in their simultaneous publication in the New England Journal of Medicine.
Room for a fifth HFrEF drug?
In addition to the limited benefit, another question raised by the trial is how OM would perform when used on top of what is now considered standard, quadruple therapy for most HFrEF patients: a beta-blocker, a mineralocorticoid receptor antagonist, sacubitril-valsartan (Entresto), and an agent from the sodium glucose co-transporter 2 (SGLT2) inhibitor class, specifically dapagliflozin (Farxiga) or empagliflozin (Jardiance). During the period when the new OM trial was run, 2017-2019, the SGLT2 inhibitors had not yet been established as a key part of standard HFrEF treatment, and hence fewer than 3% of enrolled patients were on one of these drugs.
Because of this evidence gap, OM “can’t be across the board a fifth drug on top of standard treatment,” based on the new results, cautioned Dr. Heidenreich, a cardiologist and professor of medicine at Stanford (Calif.) University School of Medicine.
The new evidence for OM’s efficacy is “not compelling” when compared with what dapagliflozin and empagliflozin each showed in recent trials, with the SGLT2 inhibitors producing about a 25% cut compared with placebo in a primary outcome that was similar to the one used in the OM trial, commented Douglas L. Mann, MD, a heart failure physician and professor of medicine at Washington University School of Medicine in St. Louis. “Would OM still show a benefit with an SGLT2 inhibitor? That’s not known” on the basis of the available data, he said in an interview.
A related factor that could influence potential use of OM in routine practice is that with four established, foundational drug classes, adding a fifth drug that will only be available in a branded formulation raises issues of incremental cost and compliance issues, Dr. Mann noted.
The positives of omecamtiv mercarbil
But in addition to its positive result in the GALACTIC-HF trial, treatment with OM showed other attractive characteristics in a study that treated a wide spectrum of 4,120 patients with HFrEF as well as including 4,112 patients randomized to placebo. Most notably, OM had a very clean safety profile, with adverse event rates similar to placebo patients across all adverse event subtypes, as well as causing no drop in blood pressure and actually an average 2.0–mm Hg increase in systolic blood pressure, no increase in potassium, no apparent impact on renal function, and a small but significant decline in N-terminal pro-B-type natriuretic peptide (NT-proBNP) compared with placebo.
This coupled with the novel mechanism of action of OM – direct augmentation of cardiac sarcomere function by increasing myosin attachment to actin – suggests that OM can be safely added on top of existing HFrEF treatment to provide an unique and incremental benefit.
“Other heart failure drugs [like beta-blockers and sacubitril-valsartan] lower blood pressure, so what can happen is that clinicians run out of room to add full dosages” when patients’ pressures fall too low, commented Gregory D. Lewis, MD, head of Heart Failure at Massachusetts General Hospital in Boston. He is principle investigator for another OM trial, METEORIC-HF, which is examining the possible impact of the drug on exercise capacity in a randomized study with about 270 HFrEF patients.
If the METEORIC-HF results can could confirm some of the GALACTIC-HF results that suggested improvements in patient function, the combined data could potentially lead to regulatory approval for U.S. marketing of the drug, Dr. Lewis suggested. Results from that study are expected in 2021, he said in an interview.
The GALACTIC-HF results hinted at possible functional improvement after 24 weeks on treatment among patients who required hospitalization as measured by the Kansas City Cardiomyopathy Questionnaire, which measures quality life. However, this difference failed to meet the study’s prespecified definition of a significant effect.
Another intriguing suggestion of focused benefit was in patients with a left ventricular ejection fraction at or below the median in GALACTIC-HF of 28%. In that subgroup, OM treatment was linked with a significant 16% relative reduction in the primary endpoint compared with placebo, while it had no significant effect in the other 50% of patients with higher ejection fractions. (The maximum left ventricular ejection fraction for enrollment was 35%.) This apparent subgroup interaction was statistically significant, reported Dr. Teerlink, a professor of medicine at the University of California, San Francisco, and director of Heart Failure at the San Francisco V.A. Medical Center.
Further analysis of the study data “will provide greater insight into subgroups who may demonstrate greater benefit, such as patients with lower ejection fraction in whom improving cardiac function may have a greater role,” he said. The idea that a drug that improves myocyte function at the molecular level could especially benefit patients with the lowest ejection fractions is “biologically plausible,” Dr. Teerlink said.
This scenario looks reasonable, and could make OM something of a niche drug for at least the near term, said Dr. Mann.
The world’s first myotropic drug
Possibly the most notable aspect of GALACTIC-HF is that it proved the efficacy, modest though it was, of a novel drug mechanism that fulfills a decades-long quest of heart failure researchers: a safe way to improve the heart’s pumping action.
“For years, the heart failure community struggled with treatment to improve cardiac performance, but invariably it ended in disaster by worsening cardiac deaths,” problems that led to abandonment of early inotropic drugs more than a generation ago, noted Dr. Mann.
But a more nuanced approach to inotropic agents recently has emerged from Dr. Teerlink and his associates, built on the premise that the dangers seen years ago related to the calcium modulations they caused. Their new paradigm is that the dangers of these “calcitropic” agents can be sidestepped with different agents that either mediate their effects via myosin, the myotropes like OM, or mitochondrial effects from mitotropic drugs.
The inotrope debacle from the 1990s made that drug-class name “a dirty word that causes fear and loathing in the heart failure community,” observed Dr. Mann. While the term myotrope has not yet really caught on, “If omecamtiv mecarbil starts getting used in routine practice, then I think you’ll start seeing uptake of the term myotrope,” he predicted.
GALACTIC-HF was sponsored by Amgen, Cytokinetics, and Servier, the companies developing omecamtiv mecarbil. Dr. Teerlink has received research support from and been a consultant to Amgen, Cytokinetics, and Servier, as well as Abbott, AstraZeneca, Bayer, Boehringer Ingelheim, Bristol-Myers Squibb, Medtronic, Merck, and Novartis. Dr. Heidenreich had no disclosures. Dr. Mann is on a steering committee for a trial sponsored by Novartis and has no other commercial disclosures. Dr. Lewis is principal investigator for a trial of omecamtiv mecarbil and has no other commercial disclosures.

The GALACTIC-HF results hinted at possible functional improvement after 24 weeks on treatment among patients who required hospitalization as measured by the Kansas City Cardiomyopathy Questionnaire, which measures quality life. However, this difference failed to meet the study’s prespecified definition of a significant effect.
Another intriguing suggestion of focused benefit was in patients with a left ventricular ejection fraction at or below the median in GALACTIC-HF of 28%. In that subgroup, OM treatment was linked with a significant 16% relative reduction in the primary endpoint compared with placebo, while it had no significant effect in the other 50% of patients with higher ejection fractions. (The maximum left ventricular ejection fraction for enrollment was 35%.) This apparent subgroup interaction was statistically significant, reported Dr. Teerlink, a professor of medicine at the University of California, San Francisco, and director of Heart Failure at the San Francisco V.A. Medical Center.
Further analysis of the study data “will provide greater insight into subgroups who may demonstrate greater benefit, such as patients with lower ejection fraction in whom improving cardiac function may have a greater role,” he said. The idea that a drug that improves myocyte function at the molecular level could especially benefit patients with the lowest ejection fractions is “biologically plausible,” Dr. Teerlink said.
This scenario looks reasonable, and could make OM something of a niche drug for at least the near term, said Dr. Mann.
The world’s first myotropic drug
Possibly the most notable aspect of GALACTIC-HF is that it proved the efficacy, modest though it was, of a novel drug mechanism that fulfills a decades-long quest of heart failure researchers: a safe way to improve the heart’s pumping action.
“For years, the heart failure community struggled with treatment to improve cardiac performance, but invariably it ended in disaster by worsening cardiac deaths,” problems that led to abandonment of early inotropic drugs more than a generation ago, noted Dr. Mann.
But a more nuanced approach to inotropic agents recently has emerged from Dr. Teerlink and his associates, built on the premise that the dangers seen years ago related to the calcium modulations they caused. Their new paradigm is that the dangers of these “calcitropic” agents can be sidestepped with different agents that either mediate their effects via myosin, the myotropes like OM, or mitochondrial effects from mitotropic drugs.
The inotrope debacle from the 1990s made that drug-class name “a dirty word that causes fear and loathing in the heart failure community,” observed Dr. Mann. While the term myotrope has not yet really caught on, “If omecamtiv mecarbil starts getting used in routine practice, then I think you’ll start seeing uptake of the term myotrope,” he predicted.
GALACTIC-HF was sponsored by Amgen, Cytokinetics, and Servier, the companies developing omecamtiv mecarbil. Dr. Teerlink has received research support from and been a consultant to Amgen, Cytokinetics, and Servier, as well as Abbott, AstraZeneca, Bayer, Boehringer Ingelheim, Bristol-Myers Squibb, Medtronic, Merck, and Novartis.

Omecamtiv mecarbil, a member of the novel myotropic drug class that improves cardiac performance, safely produced a significant but modest improvement in heart failure events or cardiovascular death in a pivotal trial with HFrEF patients, leaving experts unsure about the role this drug could have on top of an already crowded list of four first-line drug classes for this condition.
“It remains to be investigated and discussed where omecamtiv mecarbil fits in” the overall approach to treating patients with heart failure with reduced ejection fraction (HFrEF), commented Paul Heidenreich, MD, designated discussant for the report at the virtual scientific sessions of the American Heart Association.
Omecamtiv mecarbil (OM) treatment produced a positive result for the study’s primary endpoint, with a 2.1% absolute cut in the combined rate of cardiovascular death, first heart failure hospitalization, or first urgent visit for heart failure compared with placebo during a median follow-up of about 22 months This represented an 8% relative risk reduction, reported John R. Teerlink, MD, at the meeting, and broke down as a 0.6% absolute drop in cardiovascular death compared with the placebo arm, a 0.7% cut in heart failure hospitalization, and a 0.8% drop in urgent outpatient visits for heart failure. Dr. Teerlink and his associates called this benefit “modest” in their simultaneous publication in the New England Journal of Medicine.
Room for a fifth HFrEF drug?
In addition to the limited benefit, another question raised by the trial is how OM would perform when used on top of what is now considered standard, quadruple therapy for most HFrEF patients: a beta-blocker, a mineralocorticoid receptor antagonist, sacubitril-valsartan (Entresto), and an agent from the sodium glucose co-transporter 2 (SGLT2) inhibitor class, specifically dapagliflozin (Farxiga) or empagliflozin (Jardiance). During the period when the new OM trial was run, 2017-2019, the SGLT2 inhibitors had not yet been established as a key part of standard HFrEF treatment, and hence fewer than 3% of enrolled patients were on one of these drugs.
Because of this evidence gap, OM “can’t be across the board a fifth drug on top of standard treatment,” based on the new results, cautioned Dr. Heidenreich, a cardiologist and professor of medicine at Stanford (Calif.) University School of Medicine.
The new evidence for OM’s efficacy is “not compelling” when compared with what dapagliflozin and empagliflozin each showed in recent trials, with the SGLT2 inhibitors producing about a 25% cut compared with placebo in a primary outcome that was similar to the one used in the OM trial, commented Douglas L. Mann, MD, a heart failure physician and professor of medicine at Washington University School of Medicine in St. Louis. “Would OM still show a benefit with an SGLT2 inhibitor? That’s not known” on the basis of the available data, he said in an interview.
A related factor that could influence potential use of OM in routine practice is that with four established, foundational drug classes, adding a fifth drug that will only be available in a branded formulation raises issues of incremental cost and compliance issues, Dr. Mann noted.
The positives of omecamtiv mercarbil
But in addition to its positive result in the GALACTIC-HF trial, treatment with OM showed other attractive characteristics in a study that treated a wide spectrum of 4,120 patients with HFrEF as well as including 4,112 patients randomized to placebo. Most notably, OM had a very clean safety profile, with adverse event rates similar to placebo patients across all adverse event subtypes, as well as causing no drop in blood pressure and actually an average 2.0–mm Hg increase in systolic blood pressure, no increase in potassium, no apparent impact on renal function, and a small but significant decline in N-terminal pro-B-type natriuretic peptide (NT-proBNP) compared with placebo.
This coupled with the novel mechanism of action of OM – direct augmentation of cardiac sarcomere function by increasing myosin attachment to actin – suggests that OM can be safely added on top of existing HFrEF treatment to provide an unique and incremental benefit.
“Other heart failure drugs [like beta-blockers and sacubitril-valsartan] lower blood pressure, so what can happen is that clinicians run out of room to add full dosages” when patients’ pressures fall too low, commented Gregory D. Lewis, MD, head of Heart Failure at Massachusetts General Hospital in Boston. He is principle investigator for another OM trial, METEORIC-HF, which is examining the possible impact of the drug on exercise capacity in a randomized study with about 270 HFrEF patients.
If the METEORIC-HF results can could confirm some of the GALACTIC-HF results that suggested improvements in patient function, the combined data could potentially lead to regulatory approval for U.S. marketing of the drug, Dr. Lewis suggested. Results from that study are expected in 2021, he said in an interview.

FROM AHA 2020
No link shown between thyroid dysfunction and heart failure
Thyroid dysfunction had virtually no independent impact on survival in a retrospective study of nearly 5,000 English patients with chronic heart failure, adding to evidence that subclinical thyroid disorders in these patients requires no special management beyond ongoing monitoring.
“Although thyroid dysfunction is related to outcome in patients with chronic heart failure, the association disappears when adjustment is made for established prognostic variables, such as age, NT-proBNP [N-terminal of the prohormone brain natriuretic peptide], and [New York Heart Association] class,” wrote Nathan A. Samuel, MBChB, and coauthors in the American Journal of Cardiology.
Results from several earlier studies had shown evidence for reduced survival in heart failure patients with thyroid dysfunction, but in analyses that did not adjust for heart failure severity, such as a 2013 report that used data from the Sudden Cardiac Death in Heart Failure Trial SCD-HeFT. Other studies that adjusted for heart failure severity based on serum level of natriuretic peptides did not show significant associations between thyroid function and mortality, and when those results couple with the new report they together minimize the immediate risk from subclinical thyroid dysfunction faced by heart failure patients, wrote the authors of the new report.
Don’t treat subclinical thyroid dysfunction
“Our results suggest that subclinical thyroid disease has little impact on outcomes, and that we should not treat subclinical hypothyroidism in the expectation of improving outlook,” said Andrew L. Clark, MD, senior author on the new report and professor and head of the department of academic cardiology at Hull (England) York Medical School.
“Both hyper-and hypothyroidism can cause heart failure, so thyroid function should always be checked in patients when they present with heart failure. A small proportion of patients have heart failure that is potentially reversible” with thyroid-directed treatment, Dr. Clark said in an interview.
But “subclinical disease should probably not be treated, although we have not conducted a clinical trial that proves this assertion. We speculate, based on our findings, that such a trial is unlikely to be positive.”
Patients with subclinical thyroid disorders, particularly subclinical hypothyroidism, “need to be followed and treated should they develop clinical disease,” he maintained. “Except in extreme circumstances, such as the handful of patients who might have gross myxedema and may be near coma, thyroid replacement therapy for those [with heart failure] who have clinical hypothyroidism should follow standard lines.”
It is important to monitor thyroid function,” agreed Dr. Samuel, a researcher in the department of academic cardiology at Hull York Medical School. “We found that thyroxine use was most common among patients with hyperthyroidism, suggesting that they were previously hypothyroid and had received inappropriate treatment.”
Confounder adjustment mitigates the thyroid link
The new analysis used data collected from 6,782 consecutive heart failure patients enrolled during 2000-2018 at a community heart failure clinic that serves patients in the region of Hull, England. The researchers identified 4,992 of these patients with confirmed heart failure and adequate data for their analyses, including 2,997 (60%) with heart failure with reduced ejection fraction (HFrEF) and 1,995 (40%) with heart failure with normal ejection fraction (HFnEF, the term used by the authors but often called heart failure with preserved ejection fraction).
Thyroid hormone levels showed that 90% of these patients were euthyroid, 6% were hyperthyroid, and 4% were hypothyroid, rates consistent with prior reports for both the general population and heart failure patients. Only 12 patients (0.2%) had overt hypothyroidism, and fewer that 1% (about 45 patients) had overt hyperthyroidism. Patients averaged about 73 years of age, and during a median 4.6 years of follow-up 58% died.
Both the hypo- and hyperthyroid patients showed significantly higher mortality rates than euthyroid patients in a univariate analysis. But the patients with thyroid dysfunction also had more comorbidities, more severe heart failure symptoms measured by NYHA functional class, and more severe heart failure measured as higher serum levels of NT-proBNP.
In a multivariate analysis that adjusted for these factors, the significant differences disappeared among the entire group of heart failure patients for the outcomes of all-cause mortality, and mortality or hospitalization with heart failure. The multivariate analysis also showed no significant association between higher levels of thyroid-stimulating hormone (TSH) and all-cause death or death plus heart failure hospitalization among the patients with HFrEF.
Among patients with HFnEF, the multivariate adjusted analysis showed a small increase in both mortality and mortality plus hospitalization for heart failure, a 2% rise for each of these two endpoints for each 1 mIU/L increase in TSH, the authors reported. Although the P value for each of these two significant differences among patients with HFnEF was .02, the 95% confidence interval included 1.00 and ranged from 1.00 to 1.04.
The multivariate analysis identified three variables with the strongest associations with all-cause mortality: older age, higher levels of NT-proBNP, and higher NYHA class indicating greater functional impairment.
The results support the hypothesis that “worsening heart failure can lead to down-regulation of thyroid hormone signaling,” the authors suggested. Their study is also “the first to examine the prognostic significance of thyroid dysfunction in a large population of patients with HFnEF.” This analysis showed a “weak but significant association between increasing TSH and both mortality and the composite endpoint in patients with HFnEF.”
“HFnEF is a heterogeneous group of conditions that are difficult to diagnose in many cases. Therefore, future studies are needed to provide further clarity on the effect of thyroid dysfunction in these patients,” Dr. Samuel said.
The study received no commercial funding. Dr. Samuel and Dr. Clark had no disclosures.

New return-to-play recommendations for athletes with COVID-19
The latest recommendations from sports cardiologists on getting athletes with COVID-19 back on the playing field safely emphasize a more judicious approach to screening for cardiac injury.
The new recommendations, made by the American College of Cardiology’s Sports and Exercise Cardiology Section, are for adult athletes in competitive sports and also for two important groups: younger athletes taking part in competitive high school sports and older athletes aged 35 and older, the Masters athletes, who continue to be active throughout their lives. The document was published online in JAMA Cardiology.
Because of the evolving nature of knowledge about COVID-19, updates on recommendations for safe return to play for athletes of all ages will continue to be made, senior author Aaron L. Baggish, MD, director of the cardiovascular performance program at Massachusetts General Hospital, Boston, said.
“The recommendations we released in May were entirely based on our experience taking care of hospitalized patients with COVID-19; we had no athletes in this population. We used a lot of conservative guesswork around how this would apply to otherwise healthy athletes,” Dr. Baggish said in an interview.
“But as sports started to open up, and we started to see large numbers of first professional and then college athletes come back into training, we realized that we needed to stop and ask whether the recommendations we put forward back in May were still appropriate,” Dr. Baggish said.
“Once we started to actually get into the trenches with these athletes, literally hundreds of them, and applying the testing strategies that we had initially recommended in everybody, we realized that we probably had some room for improvement, and that’s why we reconvened, to make these revisions,” he said.
Essentially, the recommendations now urge less cardiac testing. “Cardiac injury is not as common as we may have originally thought,” said Dr. Baggish.
“In the early days of COVID, people who were hospitalized had evidence of heart injury, and so we wondered if that prevalence would also be applicable to otherwise young, healthy people who got COVID. If that had been the case, we would have been in big trouble with respect to getting people back into sports. So this is why we started with a conservative screening approach and a lot of testing in order to not miss a huge burden of disease,” he said.
“But what we’ve learned over the past few months is that young people who get either asymptomatic or mild infection appear to have very, very low risk of having associated heart injury, so the need for testing in that population, when people who have infections recover fully, is almost certainly not going to be high yield,” Dr. Baggish said.
First iteration of the recommendations
Published in May in the early weeks of the pandemic, the first recommendations for safe return to play said that all athletes should stop training for at least 2 weeks after their symptoms resolve, then undergo “careful, clinical cardiovascular evaluation in combination with cardiac biomarkers and imaging.”
Additional testing with cardiac MRI, exercise testing, or ambulatory rhythm monitoring was to be done “based on the clinical course and initial testing.”
But experts caution that monitoring on such a scale in everyone is unnecessary and could even be counterproductive.
“Sending young athletes for extensive testing is not warranted and could send them to unnecessary testing, cardiac imaging, and so on,” Dr. Baggish said.
Only those athletes who continue to have symptoms or whose symptoms return when they get back to their athletic activities should go on for more screening.
“There, in essence, is the single main change from May, and that is a move away from screening with testing everyone, [and instead] confining that to the people who had moderate or greater severity disease,” he said.
Both iterations of the recommendations end with the same message.
“We are at the beginning of our knowledge about the cardiotoxic effects of COVID-19 but we are gathering evidence every day,” said Dr. Baggish. “Just as they did earlier, we acknowledge that our approaches are subject to change when we learn more about how COVID affects the heart, and specifically the hearts of athletes. This will be an ongoing process.”
Something to lean on
The recommendations are welcome, said James E. Udelson, MD, chief of the division of cardiology at Tufts Medical Center, Boston, coauthor of an accompanying editorial.
“It was a bit of the wild west out there, because each university, each college, all with good intentions, had been all struggling to figure out what to do, and how much to do. Probably the most important message from this new paper is the fact that now there is something out there that all coaches, athletes, families, schools, trainers can get some guidance from,” Dr. Udelson said in an interview.
Refining the cardiac screening criteria was a necessary step, Dr. Udelson said.
“How much cardiac imaging do you do? That is a matter of controversy,” said Dr. Udelson, who coauthored the commentary with Tufts cardiologist Ethan Rowin, MD, and Michael A. Curtis, MEd, a certified strength and conditioning specialist at the University of Virginia, Charlottesville. “The problem is that if you use a very sensitive imaging test on a lot of people, sometimes you find things that you really didn’t need to know about. They’re really not important. And now, the athlete is told he or she cannot play for 3 months because they might have myocarditis.
“Should we be too sensitive, meaning do we want to pick up anything no matter whether it’s important or not?” he added. “There will be a lot of false positives, and we are going to disqualify a lot of people. Or do you tune it a different way?”
Dr. Udelson said he would like to see commercial sports donate money to support research into the potential cardiotoxicity of COVID-19.
“If the organizations that benefit from these athletes, like the National Collegiate Athletic Association and professional sports leagues, can fund some of this research, that would be a huge help,” Dr. Udelson said.

The latest recommendations from sports cardiologists on getting athletes with COVID-19 back on the playing field safely emphasize a more judicious approach to screening for cardiac injury.
The new recommendations, made by the American College of Cardiology’s Sports and Exercise Cardiology Section, are for adult athletes in competitive sports and also for two important groups: younger athletes taking part in competitive high school sports and older athletes aged 35 and older, the Masters athletes, who continue to be active throughout their lives. The document was published online in JAMA Cardiology.
Because of the evolving nature of knowledge about COVID-19, updates on recommendations for safe return to play for athletes of all ages will continue to be made, senior author Aaron L. Baggish, MD, director of the cardiovascular performance program at Massachusetts General Hospital, Boston, said.
“The recommendations we released in May were entirely based on our experience taking care of hospitalized patients with COVID-19; we had no athletes in this population. We used a lot of conservative guesswork around how this would apply to otherwise healthy athletes,” Dr. Baggish said in an interview.
“But as sports started to open up, and we started to see large numbers of first professional and then college athletes come back into training, we realized that we needed to stop and ask whether the recommendations we put forward back in May were still appropriate,” Dr. Baggish said.
“Once we started to actually get into the trenches with these athletes, literally hundreds of them, and applying the testing strategies that we had initially recommended in everybody, we realized that we probably had some room for improvement, and that’s why we reconvened, to make these revisions,” he said.
Essentially, the recommendations now urge less cardiac testing. “Cardiac injury is not as common as we may have originally thought,” said Dr. Baggish.
“In the early days of COVID, people who were hospitalized had evidence of heart injury, and so we wondered if that prevalence would also be applicable to otherwise young, healthy people who got COVID. If that had been the case, we would have been in big trouble with respect to getting people back into sports. So this is why we started with a conservative screening approach and a lot of testing in order to not miss a huge burden of disease,” he said.
“But what we’ve learned over the past few months is that young people who get either asymptomatic or mild infection appear to have very, very low risk of having associated heart injury, so the need for testing in that population, when people who have infections recover fully, is almost certainly not going to be high yield,” Dr. Baggish said.
First iteration of the recommendations
Published in May in the early weeks of the pandemic, the first recommendations for safe return to play said that all athletes should stop training for at least 2 weeks after their symptoms resolve, then undergo “careful, clinical cardiovascular evaluation in combination with cardiac biomarkers and imaging.”
Additional testing with cardiac MRI, exercise testing, or ambulatory rhythm monitoring was to be done “based on the clinical course and initial testing.”
But experts caution that monitoring on such a scale in everyone is unnecessary and could even be counterproductive.
“Sending young athletes for extensive testing is not warranted and could send them to unnecessary testing, cardiac imaging, and so on,” Dr. Baggish said.
Only those athletes who continue to have symptoms or whose symptoms return when they get back to their athletic activities should go on for more screening.
“There, in essence, is the single main change from May, and that is a move away from screening with testing everyone, [and instead] confining that to the people who had moderate or greater severity disease,” he said.
Both iterations of the recommendations end with the same message.
“We are at the beginning of our knowledge about the cardiotoxic effects of COVID-19 but we are gathering evidence every day,” said Dr. Baggish. “Just as they did earlier, we acknowledge that our approaches are subject to change when we learn more about how COVID affects the heart, and specifically the hearts of athletes. This will be an ongoing process.”
Something to lean on
The recommendations are welcome, said James E. Udelson, MD, chief of the division of cardiology at Tufts Medical Center, Boston, coauthor of an accompanying editorial.
“It was a bit of the wild west out there, because each university, each college, all with good intentions, had been all struggling to figure out what to do, and how much to do. Probably the most important message from this new paper is the fact that now there is something out there that all coaches, athletes, families, schools, trainers can get some guidance from,” Dr. Udelson said in an interview.
Refining the cardiac screening criteria was a necessary step, Dr. Udelson said.
“How much cardiac imaging do you do? That is a matter of controversy,” said Dr. Udelson, who coauthored the commentary with Tufts cardiologist Ethan Rowin, MD, and Michael A. Curtis, MEd, a certified strength and conditioning specialist at the University of Virginia, Charlottesville. “The problem is that if you use a very sensitive imaging test on a lot of people, sometimes you find things that you really didn’t need to know about. They’re really not important. And now, the athlete is told he or she cannot play for 3 months because they might have myocarditis.
“Should we be too sensitive, meaning do we want to pick up anything no matter whether it’s important or not?” he added. “There will be a lot of false positives, and we are going to disqualify a lot of people. Or do you tune it a different way?”
Dr. Udelson said he would like to see commercial sports donate money to support research into the potential cardiotoxicity of COVID-19.
“If the organizations that benefit from these athletes, like the National Collegiate Athletic Association and professional sports leagues, can fund some of this research, that would be a huge help,” Dr. Udelson said.

Medicare fines half of hospitals for readmitting too many patients
Nearly half the nation’s hospitals, many of which are still wrestling with the financial fallout of the unexpected coronavirus, will get lower payments for all Medicare patients because of their history of readmitting patients, federal records show.
The penalties are the ninth annual round of the Hospital Readmissions Reduction Program created as part of the Affordable Care Act’s broader effort to improve quality and lower costs. The latest penalties are calculated using each hospital case history between July 2016 and June 2019, so the flood of coronavirus patients that have swamped hospitals this year were not included.
The Centers for Medicare & Medicaid Services announced in September it may suspend the penalty program in the future if the chaos surrounding the pandemic, including the spring’s moratorium on elective surgeries, makes it too difficult to assess hospital performance.
For this year, the penalties remain in effect. Retroactive to the federal fiscal year that began Oct. 1, Medicare will lower a year’s worth of payments to 2,545 hospitals, the data show. The average reduction is 0.69%, with 613 hospitals receiving a penalty of 1% or more.
Out of 5,267 hospitals in the country, Congress has exempted 2,176 from the threat of penalties, either because they are critical access hospitals – defined as the only inpatient facility in an area – or hospitals that specialize in psychiatric patients, children, veterans, rehabilitation or long-term care. Of the 3,080 hospitals CMS evaluated, 83% received a penalty.
The number and severity of penalties were comparable to those of recent years, although the number of hospitals receiving the maximum penalty of 3% dropped from 56 to 39. Because the penalties are applied to new admission payments, the total dollar amount each hospital will lose will not be known until after the fiscal year ends on July 30.
“It’s unfortunate that hospitals will face readmission penalties in fiscal year 2021,” said Akin Demehin, director of policy at the American Hospital Association. “Given the financial strain that hospitals are under, every dollar counts, and the impact of any penalty is significant.”
The penalties are based on readmissions of Medicare patients who initially came to the hospital with diagnoses of congestive heart failure, heart attack, pneumonia, chronic obstructive pulmonary disease, hip or knee replacement, or coronary artery bypass graft surgery. Medicare counts as a readmission any of those patients who ended up back in any hospital within 30 days of discharge, except for planned returns like a second phase of surgery.
A hospital will be penalized if its readmission rate is higher than expected given the national trends in any one of those categories.
The industry has disapproved of the program since its inception, complaining the measures aren’t precise and it unfairly punishes hospitals that treat low-income patients, who often don’t have the resources to ensure their recoveries are successful.
Michael Millenson, a health quality consultant who focuses on patient safety, said the penalties are a useful but imperfect mechanism to push hospitals to improve their care. The designers of the penalty system envisioned it as a way to neutralize the economic benefit hospitals get from readmitted patients under Medicare’s fee-for-service payment model, as they are otherwise paid for two stays instead of just one.
“Every industry complains the penalties are too harsh,” he said. “if you’re going to tell me we don’t need any economic incentives to do the right thing because we’re always doing the right thing – that’s not true.”

MADIT-CRT: Resynchronization linked to fewer heart failure hospitalizations
Patients with mild heart failure who received a cardiac resynchronization device had significantly reduced rates of hospitalizations for heart failure during follow-up of 1,820 patients for an average of 5.6 years, identifying in this post hoc analysis another benefit from this device that patients potentially receive in addition to an established survival advantage.
Extended follow-up of patients enrolled in the MADIT-CRT trial showed that patients with either New York Heart Association (NYHA) class I or II cardiomyopathy who received a cardiac resynchronization device with a defibrillator (CRT-D) had a significant reduction in all-cause hospitalization during follow-up, compared with control patients randomized to receive an implantable cardioverter defibrillator (ICD) device. This reduction in all hospitalizations was specifically driven by a significant reduction in cardiovascular hospitalizations, and the drop in cardiovascular hospitalizations was specifically driven by a cut in hospitalizations for heart failure (HHF), Sabu Thomas, MD, said at the annual scientific meeting of the Heart Failure Society of America.
The data showed that during follow-up all-cause hospitalizations occurred in 73% of the CRT-D patients and 83% of those who received an ICD; cardiovascular hospitalizations happened in 29% of the CRT-D patients and in 43% of those with an ICD; and HHF occurred in 12% of the CRT-D patients and in 22% of those with an ICD, reported Dr. Thomas, a heart failure cardiologist at the University of Rochester (N.Y.) Medical Center. All three between-group differences were statistically significant for these post hoc endpoints.
These reduced hospitalizations also linked with better survival. Patients in the trial database with cardiovascular hospitalizations had a nearly fourfold higher rate of death, compared with nonhospitalized patients, Dr. Thomas said.
The findings “suggest that this device [CRT-D] has sustained benefit in these patients for up to 7 years,” said Dr. Thomas and his collaborator, Valentina Kutyifa, MD, in an interview. “However, this was only seen in patients with left bundle branch block [LBBB].” In patients with non-LBBB, CRT-D was not associated with a reduction in [cardiovascular] hospitalizations.
The LBBB connection
In a multivariate analysis, the 1,281 patients with LBBB (70% of the study cohort) who were more than 6 months out from device placement had a significant 43% relative cut in their incidence of cardiovascular hospitalizations, compared with that of control patients who received an ICD, while the 537 patients with non-LBBB showed no benefit from CRT-D treatment, compared with those who received an ICD, for reducing cardiovascular hospitalizations. (Data from two enrolled patients weren’t available for the analyses.) This finding that the HHF benefit focused in patients with LBBB was consistent with many prior observations that CRT-D was most effective in this patient subgroup.
The researchers also highlighted that their findings apply only to patients with NYHA functional class I or II heart failure with reduced ejection fraction (HFrEF), the only types of patients enrolled in the MADIT-CRT trial (15% had class I disease).
The results also showed that, during the first 6 months on CRT-D treatment, patients with a LBBB showed a significant 43% increase in their cardiovascular hospitalizations, compared with control patients, which may have been driven by device-related events. “We did not investigate this in detail, and it needs more study,” said Dr. Thomas and Dr. Kutyifa, a cardiac electrophysiologist at the University of Rochester.Their new findings extend the initial, prespecified results of the MADIT-CRT (Multicenter Automatic Defibrillator Implantation With Cardiac Resynchronization Therapy) trial, which was designed to examine a primary endpoint of death from any cause or a nonfatal heart failure event. During the initial average follow-up of 2.4 years, patients who received a CRT-D device had a significant relative reduction in this endpoint of 34%, compared with patients on ICD treatment, exclusively in patients with LBBB. Extended follow-up for as long as 7 years of the same cohort showed a continued significant reduction of all-cause death compared with controls, a 41% relative risk reduction, that again was only apparent in patients with LBBB.
The MADIT-CRT findings are generally consistent with prevailing CRT-D recommendations from the American College of Cardiology and American Heart Association from 2013 that give a class I indication (“is indicated”) for using the device in heart failure patients with LBBB, a QRS interval of at least 150 msec, NYHA class II-IV function, and a left ventricular ejection fraction no greater than 35%. A lesser, class IIa recommendation (“can be useful”) exists for patients with a narrower QRS of 120-149 msec with the other class I criteria, and for patients with non-LBBB the recommendation drops to class IIb (“may be considered”).
CRT-D ‘is mysterious,’ especially for non-LBBB patients
“Every time researchers have tried to move beyond the [existing] paradigm of who benefits from CRT-D, it’s never panned out,” commented Jeffrey J. Goldberger, MD, an electrophysiologist, professor, and chief of the cardiovascular division at the University of Miami. “The guidelines are pretty correct on who should get CRT-D. I wouldn’t say that no patients with non-LBBB should get it, but they are less likely to benefit,” although he conceded that responses to CRT-D are highly individualized and hard to predict.
“CRT is mysterious. I’ve had patients who did incredibly well on it,” but “once you start getting outside of where the benefits are proven, you start to run into issues,” Dr. Goldberger said in an interview. “The only solid predictor of a CRT-D response is in patients with LBBB.”
The hospitalizations for heart failure that the University of Rochester investigators assessed as an additional study outcome represent an “important endpoint, but one that is much more subjective than survival,” making its reliability “a bit of a gray area,” he said. The analyses are also limited by being post hoc and, hence, just hypothesis generating.
A recently published analysis of the same dataset by many of the same investigators hinted that CRT-D might reduce HHF in non-LBBB patients when the focus is on recurrent hospitalizations.
Despite the evidence of a survival benefit from CRT-D placement in selected patients, especially those with LBBB, “registry data have shown that use of CRT-D varies widely and has been as low as 27% of eligible patients,” noted Dr. Thomas and Dr. Kutyifa. “There is an opportunity here to understand the barriers to more widespread adoption of CRT-D in appropriate patients,” they said. It is also “possible that CRT-D is overused in non-LBBB patients” given that this subgroup receives about a third of CRT-D devices now. “Future studies should carefully investigate the role of CRT-D in non-LBBB patients.”
MADIT-CRT was funded by Boston Scientific, which markets several CRT-D devices. Dr. Thomas had no disclosures. Dr. Kutyifa has been a consultant to Biotronik and Zoll and has received research funding from Biotronik, Boston Scientific, Spire, and Zoll. Dr Goldberger is director of a not-for-profit think tank on risk stratification for sudden cardiac death that has received unrestricted educational grants from Abbott, Biotronik, Boston Scientific, and Medtronic.

During the initial average follow-up of 2.4 years, patients who received a CRT-D device had a significant relative reduction in this endpoint of 34%, compared with patients on ICD treatment, exclusively in patients with LBBB. Extended follow-up for as long as 7 years of the same cohort showed a continued significant reduction of all-cause death compared with controls, a 41% relative risk reduction, that again was only apparent in patients with LBBB.
The MADIT-CRT findings are generally consistent with prevailing CRT-D recommendations from the American College of Cardiology and American Heart Association from 2013 that give a class I indication (“is indicated”) for using the device in heart failure patients with LBBB, a QRS interval of at least 150 msec, NYHA class II-IV function, and a left ventricular ejection fraction no greater than 35%. A lesser, class IIa recommendation (“can be useful”) exists for patients with a narrower QRS of 120-149 msec with the other class I criteria, and for patients with non-LBBB the recommendation drops to class IIb (“may be considered”).
CRT-D ‘is mysterious,’ especially for non-LBBB patients
“Every time researchers have tried to move beyond the [existing] paradigm of who benefits from CRT-D, it’s never panned out,” commented Jeffrey J. Goldberger, MD, an electrophysiologist, professor, and chief of the cardiovascular division at the University of Miami. “The guidelines are pretty correct on who should get CRT-D. I wouldn’t say that no patients with non-LBBB should get it, but they are less likely to benefit,” although he conceded that responses to CRT-D are highly individualized and hard to predict.
“CRT is mysterious. I’ve had patients who did incredibly well on it,” but “once you start getting outside of where the benefits are proven, you start to run into issues,” Dr. Goldberger said in an interview. “The only solid predictor of a CRT-D response is in patients with LBBB.”
The hospitalizations for heart failure that the University of Rochester investigators assessed as an additional study outcome represent an “important endpoint, but one that is much more subjective than survival,” making its reliability “a bit of a gray area,” he said. The analyses are also limited by being post hoc and, hence, just hypothesis generating.
A recently published analysis of the same dataset by many of the same investigators hinted that CRT-D might reduce HHF in non-LBBB patients when the focus is on recurrent hospitalizations.
Despite the evidence of a survival benefit from CRT-D placement in selected patients, especially those with LBBB, “registry data have shown that use of CRT-D varies widely and has been as low as 27% of eligible patients,” noted Dr. Thomas and Dr. Kutyifa. “There is an opportunity here to understand the barriers to more widespread adoption of CRT-D in appropriate patients,” they said. It is also “possible that CRT-D is overused in non-LBBB patients” given that this subgroup receives about a third of CRT-D devices now. “Future studies should carefully investigate the role of CRT-D in non-LBBB patients.”

Patients with mild heart failure who received a cardiac resynchronization device had significantly reduced rates of hospitalizations for heart failure during follow-up of 1,820 patients for an average of 5.6 years, identifying in this post hoc analysis another benefit from this device that patients potentially receive in addition to an established survival advantage.
Extended follow-up of patients enrolled in the MADIT-CRT trial showed that patients with either New York Heart Association (NYHA) class I or II cardiomyopathy who received a cardiac resynchronization device with a defibrillator (CRT-D) had a significant reduction in all-cause hospitalization during follow-up, compared with control patients randomized to receive an implantable cardioverter defibrillator (ICD) device. This reduction in all hospitalizations was specifically driven by a significant reduction in cardiovascular hospitalizations, and the drop in cardiovascular hospitalizations was specifically driven by a cut in hospitalizations for heart failure (HHF), Sabu Thomas, MD, said at the annual scientific meeting of the Heart Failure Society of America.
The data showed that during follow-up all-cause hospitalizations occurred in 73% of the CRT-D patients and 83% of those who received an ICD; cardiovascular hospitalizations happened in 29% of the CRT-D patients and in 43% of those with an ICD; and HHF occurred in 12% of the CRT-D patients and in 22% of those with an ICD, reported Dr. Thomas, a heart failure cardiologist at the University of Rochester (N.Y.) Medical Center. All three between-group differences were statistically significant for these post hoc endpoints.
These reduced hospitalizations also linked with better survival. Patients in the trial database with cardiovascular hospitalizations had a nearly fourfold higher rate of death, compared with nonhospitalized patients, Dr. Thomas said.
The findings “suggest that this device [CRT-D] has sustained benefit in these patients for up to 7 years,” said Dr. Thomas and his collaborator, Valentina Kutyifa, MD, in an interview. “However, this was only seen in patients with left bundle branch block [LBBB].” In patients with non-LBBB, CRT-D was not associated with a reduction in [cardiovascular] hospitalizations.
The LBBB connection
In a multivariate analysis, the 1,281 patients with LBBB (70% of the study cohort) who were more than 6 months out from device placement had a significant 43% relative cut in their incidence of cardiovascular hospitalizations, compared with that of control patients who received an ICD, while the 537 patients with non-LBBB showed no benefit from CRT-D treatment, compared with those who received an ICD, for reducing cardiovascular hospitalizations. (Data from two enrolled patients weren’t available for the analyses.) This finding that the HHF benefit focused in patients with LBBB was consistent with many prior observations that CRT-D was most effective in this patient subgroup.
The researchers also highlighted that their findings apply only to patients with NYHA functional class I or II heart failure with reduced ejection fraction (HFrEF), the only types of patients enrolled in the MADIT-CRT trial (15% had class I disease).
The results also showed that, during the first 6 months on CRT-D treatment, patients with a LBBB showed a significant 43% increase in their cardiovascular hospitalizations, compared with control patients, which may have been driven by device-related events. “We did not investigate this in detail, and it needs more study,” said Dr. Thomas and Dr. Kutyifa, a cardiac electrophysiologist at the University of Rochester.Their new findings extend the initial, prespecified results of the MADIT-CRT (Multicenter Automatic Defibrillator Implantation With Cardiac Resynchronization Therapy) trial, which was designed to examine a primary endpoint of death from any cause or a nonfatal heart failure event.

Updated heart failure measures add newer meds
Safety measures for lab monitoring of mineralocorticoid receptor agonist therapy, performance measures for sacubitril/valsartan, cardiac resynchronization therapy and titration of medications, and quality measures based on patient-reported outcomes are among the updates the joint task force of the American College of Cardiology and the American Heart Association have made to performance and quality measures for managing adults with heart failure.
The revisions, published online Nov. 2 in the Journal of the American College of Cardiology, update the 2011 ACC/AHA heart failure measure set, writing committee vice chair Gregg C. Fonarow, MD, said in an interview. The 2011 measure set predates the 2015 approval of the angiotensin receptor neprilysin inhibitor (ARNI) sacubitril/valsartan for heart failure in adults.
Measures stress dosages, strength of evidence
“For the first time the heart failure performance measure sets also focus on not just the use of guideline-recommended medication at any dose, but on utilizing the doses that are evidence-based and guideline recommended so long as they are well tolerated,” said Dr. Fonarow, interim chief of cardiology at the University of California, Los Angeles. “The measure set now includes assessment of patients being treated with doses of medications at 50% or greater of target dose in the absence of contraindications or documented intolerance.”
The update includes seven new performance measures, two quality measures, and one structural measure. The performance measures come from the strongest recommendations – that is, a class of recommendation of 1 (strong) or 3 (no benefit or harmful, process to be avoided) – in the 2017 ACC/AHA/Heart Failure Society of American heart failure guideline update published in Circulation.
In addition to the 2017 update, the writing committee also reviewed existing performance measures. “Those management strategies, diagnostic testing, medications, and devices with the strongest evidence and highest level of guideline recommendations were further considered for inclusion in the performance measure set,” Dr. Fonarow said. “The measures went through extensive review by peer reviewers and approval from the organizations represented.”
Specifically, the update includes measures for monitoring serum potassium after starting mineralocorticoid receptor antagonists therapy, and cardiac resynchronization therapy for patients with heart failure with reduced ejection fraction already on guideline-directed therapy. “This therapy can significantly improve functional capacity and outcomes in appropriately selected patients,” Dr. Fonarow said.
New and retired measures
The update adds two performance measures for titration of medications based on dose, either reaching 50% of the recommended dose for a variety of medications, including ARNI, or documenting that the dose wasn’t tolerated for other reason for not using the dose.
The new structural measure calls for facility participation in a heart failure registry. The revised measure set now consists of 18 measures in all.
The update retired one measure from the 2011 set: left ventricular ejection fraction assessment for inpatients. The committee cited its use above 97% as the reason, but LVEF in outpatients remains a measure.
The following tree measures have been revised:
- Patient self-care education has moved from performance measure to quality measure because of concerns about the accuracy of self-care education documentation and limited evidence of improved outcomes with better documentation.
- ACE inhibitor or angiotensin receptor blocker therapy for left ventricular systolic dysfunction adds ARNI therapy to align with the 2017 ACC/AHA/HFSA update.
- Postdischarge appointments shifts from performance to quality measure and include a 7-day limit.
Measures future research should focus on, noted Dr. Fonarow, include the use of sodium glucose cotransporter 2 (SGLT2) inhibitors for heart failure, including in patients without diabetes. “Since the ACC/AHA heart failure guidelines had not yet been updated to recommend these therapies they could not be included in this performance measure set,” he said.
He also said “an urgent need” exists for further research into treatments for heart failure with preserved ejection fraction along with optimal implementation strategies.
“If these ACC/AHA heart failure performance measures were applied in all settings in which patients with heart failure in the United States are being cared for, and optimal and equitable conformity with each of these measures were achieved, over 100,000 lives a year of patients with heart failure could be saved,” he said. “There’s in an urgent need to measure and improve heart failure care quality.”
Dr. Fonarow reported financial relationships with Abbott, Amgen, AstraZeneca, CHF Solutions, Janssen, Medtronic, Merck, and Novartis.
