Heart Failure

Chronic cough took center stage at the European Respiratory Society Congress session titled “Conditions We Are Just Dealing With the Tip of the Iceberg in Primary Care: Frequently Mismanaged Conditions in Primary Health Care.”

“When it comes to chronic cough, general practitioners often feel lost,” Miguel Román Rodríguez, family doctor and an associate professor of family medicine at the University of the Balearic Islands, Palma, Mallorca, Spain, and one of the chairs of the session, said to this news organization.

“GPs are central in diagnosing conditions like chronic cough. We bring something that the specialists don’t bring: the knowledge of the context, of the family, the longitudinal history,” echoed the second chair of the session, Hilary Pinnock, family physician and professor of primary care respiratory medicine at the University of Edinburgh.
 

Understanding the multifaceted nature of chronic cough

Imran Satia, an assistant professor at McMaster University, Hamilton, Ont., guided attendees at the Milan, Italy, meeting through a comprehensive exploration of chronic cough. The first issue he addressed was the definition of the condition, emphasizing that it is defined by its duration, with chronic cough typically lasting for more than 8 weeks. Prof. Satia pointed out common associations of chronic cough, including asthma, nasal disease, and reflux disease.

Delving into epidemiology, he cited a meta-analysis indicating a global prevalence of approximately 10% in the adult population, with significant regional variability: from 18.1% in Australia to 2.3% in Africa. Notably, the Canadian Longitudinal Study on Aging found an overall prevalence of 16% at baseline. “The most common risk factor was smoke, but even in nonsmokers the prevalence reached 10%,” Prof. Satia added, highlighting that it increased with age and changed depending on location. “The most common associated comorbidities were heart failure and hypertension, but also conditions related to chronic pain, mood, and anxiety,” he explained.

Mental health was identified as a crucial factor in chronic cough, with psychological distress and depressive symptoms emerging as risk factors for developing chronic cough over the next 3 years, contributing to a 20% increased risk.
 

Effective management strategies

Prof. Satia proposed the use of algorithms to aid in the management of patients with chronic cough in primary care. He introduced a Canadian algorithm that offers specific recommendations for both primary and secondary care.

The algorithm’s primary care assessment, step 1, includes a comprehensive evaluation of the cough history (duration, severity, triggers, nature, location); cardiorespiratory, gastrointestinal, and nasal symptoms; and use of angiotensin-converting enzyme inhibitors and smoking status. Essential diagnostic tests, such as chest radiography (to check for structural disease), complete blood cell count, and spirometry (with or without bronchodilator reversibility), were emphasized. Urgent referral criteria encompassed symptoms like hemoptysis, weight loss, fever, or abnormal chest radiography findings.

“When checking for cough history, GPs should always consider factors like the presence of dry or productive cough, mental health, presence of chronic pain, stroke, and swallowing,” said Prof. Satia, stressing the importance of documenting the impact of chronic cough on quality of life, work life, social life, and family life. “This is something that doctors sometimes do not ask about. They may think that these are not major problems, but acknowledging their importance can help the patient,” he added.

Step 2 of the algorithm focuses on treatment options tailored to specific diagnoses, such as asthma or chronic obstructive pulmonary disease. Prof. Satia urged caution, emphasizing that treatment should only be initiated when evidence of these conditions is present. Additionally, he encouraged early consideration of cough hypersensitivity syndrome when patients exhibit coughing in response to low levels of mechanical stimulation.
 

Current treatments and future prospects

Prof. Satia presented an overview of existing treatments for chronic cough, outlining their respective advantages and disadvantages. For instance, speech therapy is a patient-led approach with no side effects but entails challenges related to access, costs, and patient motivation. On the other hand, low-dose morphine offers rapid relief but is associated with issues like nausea, stigma, and constipation.

Looking ahead, Prof. Satia shared the results of COUGH-1 and COUGH-2, pivotal phase 3 trials evaluating the oral, peripherally acting P2X3-receptor antagonist gefapixant. This drug, currently approved in Switzerland and Japan, demonstrated a significant reduction in cough frequency, compared with placebo, with rapid and sustained effects. “The estimated relative reduction for 45 mg was 18.45% in COUGH-1 (12 weeks) and 14.64% in COUGH-2 (24 weeks). Of note, cough reduction is very quick and sustained with gefapixant, but a 40% reduction is observed in the placebo arm,” commented Prof. Satia.

Experts unanimously stressed the importance for specialists and GPs of effective communication in managing chronic cough, involving both patients and their families.

“As GPs, we are crucial to manage the common problems, but we are also crucial to spot the needle in the haystack: this is extremely difficult and challenging, and we need support from our colleagues,” Dr. Pinnock concluded.

Prof. Satia reported funding from Merck MSD, AstraZeneca, and GSK; consulting fees from Merck MSD, Genentech, and Respiplus; and speaker fees from AstraZeneca, GSK, and Merck MSD.

AMSTERDAM – For patients hospitalized for acute heart failure, initiating treatment with the SGLT2 inhibitor dapagliflozin (Farxiga, AstraZeneca) before hospital discharge was safe, it appeared to improve diuresis and natriuresis while reducing the administered diuretic dose, and it meant quicker initiation of guideline-directed therapy in a controlled study of 238 patients.

Treatment with dapagliflozin was begun for people with heart failure on their first day of hospitalization for an acute episode. Such treatment “can be safely started to optimize a key medication,” Zachary Cox, PharmD, said at the annual congress of the European Society of Cardiology. It improved fluid removal, as evidenced in the “totality of diuretic measures,” it resulted in reduced doses of IV diuretics, and it shortened length of stay in the hospital.

In current U.S. practice, about 80% of people hospitalized with heart failure do not initially receive treatment with a sodium-glucose cotransporter 2 (SGLT2) inhibitor during their hospital stay when they are not already taking an agent from the class, noted Dr. Cox, professor of pharmacy at Lipscomb University College of Pharmacy in Nashville, Tenn.

Physicians are often uncomfortable changing a patient’s medications on the first day of a hospitalization, he noted. “Our results should embolden physicians” to begin treatment with an SGLT2 inhibitor early during hospitalization and to then continue it chronically, Dr. Cox said in a press briefing.

“Despite the messaging [from guidelines], we still see hesitancy. We hope more evidence of safety will improve uptake.” The study’s “key message is to start guideline-directed medical therapy early,” prior to hospital discharge, Dr. Cox concluded.
 

“Some support” for SGLT2 inhibitors

The study results “provide some support for SGLT2 inhibitors facilitating decongestion and hospital discharge without observed safety issues,” said Stephen D. Wiviott, MD, designated discussant for the report and a cardiologist and professor at Harvard Medical School in Boston.

While initiation of an SGLT2 inhibitor during an acute heart failure hospitalization received endorsement as a top management priority in both the 2023 heart failure guidelines of the European Society of Cardiology and in 2022 U.S. guidelines, evidence of the safety and efficacy of this approach has been scanty, Dr. Wiviott noted.

Two prior studies addressed the issue. The SOLOIST-WHF trial tested the combined SGLT1 and SGLT2 inhibitor sotagliflozin (Inpefa, Lexicon) for patients recently hospitalized for heart failure, but only 142 of the 596 participants who were randomly assigned to receive sotagliflozin began receiving it at least a day before hospital discharge; for the remaining 454, treatment with sotagliflozin began on their discharge day, noted Dr. Wiviott.

In the EMPULSE trial, 530 people hospitalized for acute heart failure were randomly assigned to initially receive empagliflozin (Jardiance, Boehringer Ingelheim and Lilly) or placebo during hospitalization. The primary endpoint was largely driven by an improvement in the patient-reported outcome, as assessed on the basis of the Kansas City Cardiomyopathy Questionnaire Total Symptom Score, Dr. Wiviott added.

The DICTATE-AHF study included 238 adults who were within 24 hours of first presenting to any of six participating U.S. hospitals with hypervolemic acute heart failure. All patients underwent a standard treatment protocol with IV loop diuretics, and half received additional, open-label treatment with a daily 10-mg dose of dapagliflozin.

The average age of the patients was 65 years, 71% had type 2 diabetes (the study excluded people with type 1 diabetes), and about half had a left ventricular ejection fraction of 40% or less.
 

Similar weight loss with lower diuretics dose

The study’s primary outcome was a measure of diuretic efficiency, calculated as a person’s cumulative weight change divided by the cumulative dose of loop diuretics.

Both treatment arms experienced nearly identical weight loss, but for the people who received dapagliflozin, this occurred with a lower cumulative dose of diuretics. The diuretic efficiency with dapagliflozin produced comparable weight loss with a 35% lower amount of loop diuretic dose, a difference that fell just short of significance (P = .06).

However, treatment with dapagliflozin also significantly boosted 24-hour natriuresis and 24-hour diuresis, and it significantly shortened the time to stopping treatment with IV diuretics and to hospital discharge, Dr. Cox reported. Dapagliflozin initiation and ongoing treatment was also safe and well tolerated compared with usual care.

The fact that the primary endpoint fell short of significance was “largely related” to the study’s relatively small size, Dr. Wiviott suggested. He noted that the DAPA ACT HF-TIMI 68 study, which is a much larger and potentially more definitive study of the safety and efficacy of dapagliflozin in comparison with usual care for patients with acute heart failure, is in progress. The study includes about 2,400 patients.

The primary outcome is the combined rate of cardiovascular death or worsening heart failure during the 2 months following randomization. Results are expected in 2024.

DICTATE-AHF was sponsored by AstraZeneca, the company that markets dapagliflozin (Farxiga). Dr. Cox has received research funding from AstraZeneca and has been a consultant to Roche and Translational Catalyst. Dr. Wiviott has received research funding from AstraZeneca and from Merck and has been a consultant to Icon Clinical and Novo Nordisk.

People on Medicare may in 2026 see prices drop for 10 medicines, including pricey diabetes, cancer, blood clot, and arthritis treatments, if advocates for federal drug-price negotiations can implement their plans amid tough opposition.

The Biden administration on Aug. 29 revealed the first 10 drugs selected for direct Medicare price negotiations in accordance with a process mandated by the Inflation Reduction Act of 2022.

It’s unclear at this time, though, how these negotiations will play out. The Chamber of Commerce has sided with pharmaceutical companies in bids to block direct Medicare negotiation of drug prices. Many influential Republicans in Congress oppose this plan, which has deep support from both Democrats and AARP.

While facing strong opposition to negotiations, the Centers for Medicare & Medicaid Services sought in its announcement to illustrate the high costs of the selected medicines.

CMS provided data on total Part D costs for selected medicines for the period from June 2022 to May 2023, along with tallies of the number of people taking these drugs. The 10 selected medicines are as follows:
 

• Eliquis (generic name: apixaban), used to prevent and treat serious blood clots. It is taken by about 3.7 million people through Part D plans. The estimated cost is $16.4 billion.
• Jardiance (generic name: empagliflozin), used for diabetes and heart failure. It is taken by almost 1.6 million people through Part D plans. The estimated cost is $7.06 billion.
• Xarelto (generic name: rivaroxaban), used for blood clots. It is taken by about 1.3 million people through Part D plans. The estimated cost is $6 billion.
• Januvia (generic name: sitagliptin), used for diabetes. It is taken by about 869,00 people through Part D plans. The estimated cost is $4.1 billion.
• Farxiga (generic name: dapagliflozin), used for diabetes, heart failure, and chronic kidney disease. It is taken by about 799,000 people through Part D plans. The estimated cost is almost $3.3 billion.
• Entresto (generic name: sacubitril/valsartan), used to treat heart failure. It is taken by 587,000 people through Part D plans. The estimated cost is $2.9 billion.
• Enbrel( generic name: etanercept), used for rheumatoid arthritis, psoriasis, and psoriatic arthritis. It is taken by 48,000 people through Part D plans. The estimated cost is $2.8 billion.
• Imbruvica (generic name: ibrutinib), used to treat some blood cancers. It is taken by about 20,000 people in Part D plans. The estimated cost is $2.7 billion.
• Stelara (generic name: ustekinumab), used to treat plaque psoriasis, psoriatic arthritis, or certain bowel conditions (Crohn’s disease, ulcerative colitis). It is used by about 22,000 people through Part D plans. The estimated cost is $2.6 billion.
• Fiasp; Fiasp FlexTouch; Fiasp PenFill; NovoLog; NovoLog FlexPen; NovoLog PenFill. These are forms of insulin used to treat diabetes. They are used by about 777,000 people through Part D plans. The estimated cost is $2.6 billion.

A vocal critic of Medicare drug negotiations, Joel White, president of the Council for Affordable Health Coverage, called the announcement of the 10 drugs selected for negotiation “a hollow victory lap.” A former Republican staffer on the House Ways and Means Committee, Mr. White aided with the development of the Medicare Part D plans and has kept tabs on the pharmacy programs since its launch in 2006.

“No one’s costs will go down now or for years because of this announcement” about Part D negotiations, Mr. White said in a statement.

According to its website, CAHC includes among its members the American Academy of Ophthalmology as well as some patient groups, drugmakers, such as Johnson & Johnson, and insurers and industry groups, such as the National Association of Manufacturers.

Separately, the influential Chamber of Commerce is making a strong push to at least delay the implementation of the Medicare Part D drug negotiations. On Aug. 28, the chamber released a letter sent to the Biden administration, raising concerns about a “rush” to implement the provisions of the Inflation Reduction Act.

The chamber also has filed suit to challenge the drug negotiation provisions of the Inflation Reduction Act, requesting that the court issue a preliminary injunction by Oct. 1, 2023.

Other pending legal challenges to direct Medicare drug negotiations include suits filed by Merck, Bristol-Myers Squibb, Johnson & Johnson, Boehringer Ingelheim, and AstraZeneca, according to an email from Pharmaceutical Research and Manufacturers of America. PhRMA also said it is a party to a case.

In addition, the three congressional Republicans with most direct influence over Medicare policy issued on Aug. 29 a joint statement outlining their objections to the planned negotiations on drug prices.

This drug-negotiation proposal is “an unworkable, legally dubious scheme that will lead to higher prices for new drugs coming to market, stifle the development of new cures, and destroy jobs,” said House Energy and Commerce Committee Chair Cathy McMorris Rodgers (R-Wash.), House Ways and Means Committee Chair Jason Smith (R-Mo.), and Senate Finance Committee Ranking Member Mike Crapo (R-Idaho).

Democrats were equally firm and vocal in their support of the negotiations. Senate Finance Chairman Ron Wyden (D-Ore.) issued a statement on Aug. 29 that said the release of the list of the 10 drugs selected for Medicare drug negotiations is part of a “seismic shift in the relationship between Big Pharma, the federal government, and seniors who are counting on lower prices.

“I will be following the negotiation process closely and will fight any attempt by Big Pharma to undo or undermine the progress that’s been made,” Mr. Wyden said.

In addition, AARP issued a statement of its continued support for Medicare drug negotiations.

“The No. 1 reason seniors skip or ration their prescriptions is because they can’t afford them. This must stop,” said AARP executive vice president and chief advocacy and engagement officer Nancy LeaMond in the statement. “The big drug companies and their allies continue suing to overturn the Medicare drug price negotiation program to keep up their price gouging. We can’t allow seniors to be Big Pharma’s cash machine anymore.”

People on Medicare may in 2026 see prices drop for 10 medicines, including pricey diabetes, cancer, blood clot, and arthritis treatments, if advocates for federal drug-price negotiations can implement their plans amid tough opposition.

The Biden administration on Aug. 29 revealed the first 10 drugs selected for direct Medicare price negotiations in accordance with a process mandated by the Inflation Reduction Act of 2022.

It’s unclear at this time, though, how these negotiations will play out. The Chamber of Commerce has sided with pharmaceutical companies in bids to block direct Medicare negotiation of drug prices. Many influential Republicans in Congress oppose this plan, which has deep support from both Democrats and AARP.

While facing strong opposition to negotiations, the Centers for Medicare & Medicaid Services sought in its announcement to illustrate the high costs of the selected medicines.

CMS provided data on total Part D costs for selected medicines for the period from June 2022 to May 2023, along with tallies of the number of people taking these drugs. The 10 selected medicines are as follows:
 

• Eliquis (generic name: apixaban), used to prevent and treat serious blood clots. It is taken by about 3.7 million people through Part D plans. The estimated cost is $16.4 billion.
• Jardiance (generic name: empagliflozin), used for diabetes and heart failure. It is taken by almost 1.6 million people through Part D plans. The estimated cost is $7.06 billion.
• Xarelto (generic name: rivaroxaban), used for blood clots. It is taken by about 1.3 million people through Part D plans. The estimated cost is $6 billion.
• Januvia (generic name: sitagliptin), used for diabetes. It is taken by about 869,00 people through Part D plans. The estimated cost is $4.1 billion.
• Farxiga (generic name: dapagliflozin), used for diabetes, heart failure, and chronic kidney disease. It is taken by about 799,000 people through Part D plans. The estimated cost is almost $3.3 billion.
• Entresto (generic name: sacubitril/valsartan), used to treat heart failure. It is taken by 587,000 people through Part D plans. The estimated cost is $2.9 billion.
• Enbrel( generic name: etanercept), used for rheumatoid arthritis, psoriasis, and psoriatic arthritis. It is taken by 48,000 people through Part D plans. The estimated cost is $2.8 billion.
• Imbruvica (generic name: ibrutinib), used to treat some blood cancers. It is taken by about 20,000 people in Part D plans. The estimated cost is $2.7 billion.
• Stelara (generic name: ustekinumab), used to treat plaque psoriasis, psoriatic arthritis, or certain bowel conditions (Crohn’s disease, ulcerative colitis). It is used by about 22,000 people through Part D plans. The estimated cost is $2.6 billion.
• Fiasp; Fiasp FlexTouch; Fiasp PenFill; NovoLog; NovoLog FlexPen; NovoLog PenFill. These are forms of insulin used to treat diabetes. They are used by about 777,000 people through Part D plans. The estimated cost is $2.6 billion.

Catheter ablation had long taken atrial fibrillation (AF) rhythm control to the next level before clinical trials showed it could help keep AF patients with heart failure (HF) alive and out of the hospital.

But those trials didn’t include many patients with AF on top of advanced or even end-stage HF. Lacking much of an evidence base and often viewed as too sick to gain a lot from the procedure, patients with AF and advanced HF aren’t offered ablation very often.

Now a randomized trial suggests that, on the contrary, AF ablation may confer a similar benefit to patients with HF so advanced that they were referred for evaluation at a transplant center.

The study, modestly sized with fewer than 200 such patients and conducted at a single center, assigned half of them to receive ablation and the other half to continued medical management.

Risk for the composite primary endpoint plunged 76% over a median of 18 months for those who underwent ablation. The outcome comprised death from any cause, implantation of a left ventricular assist device (LVAD), or urgent heart transplantation.

The advantage for ablation emerged early enough that the trial, CASTLE-HTx, was halted for benefit only a year after reaching its planned enrollment, observed Christian Sohns, MD, when formally presenting the results in Amsterdam at the annual congress of the European Society of Cardiology.

The difference in the primary endpoint “in this severely sick cohort of advanced, end-stage heart failure patients,” he said, was driven mostly by fewer deaths, especially cardiovascular deaths, in the ablation group.

Ablation’s effect on outcomes was associated, perhaps causally, with significant gains in left ventricular (LV) function and more than triple the reduction in AF burden seen in the control group, noted Dr. Sohns, from the Heart and Diabetes Center North-Rhine Westphalia, Bad Oeynhausen, Germany.

“Our trial suggests that in patients with atrial fibrillation and end-stage heart failure, catheter ablation may ameliorate the clinical course,” states the CASTLE-HTx primary report, published in the New England Journal of Medicine, with Dr. Sohns as lead author, in tandem with his ESC presentation.

One of the study’s key messages “is that AF ablation is safe and effective in patients with end-stage heart failure” and “should be part of our armamentarium” for treating them, said Philipp Sommer, MD, also with Heart and Diabetes Center North-Rhine Westphalia, at a press conference preceding Dr. Sohns’ presentation of CASTLE-HTx.

The intervention could potentially help such patients survive longer on transplant wait lists and even delay need for the surgery, proposed Dr. Sommer, who is senior author on the trial’s publication.

CASTLE-HTx suggests that patients with advanced HF and even persistent AF, “if they have reasonably small atria, should be actually considered for ablation, as it may prevent the need for heart transplant or LVAD implant,” said invited discussant Finn Gustafsson, MD, PhD, DMSc, after Dr. Sohns’ presentation. “And that, of course, would be a huge achievement.”

The trial “should, if anything, help eradicate the current somewhat nihilistic approach to atrial fibrillation management in patients with advanced heart failure,” said Dr. Gustafsson, medical director of cardiac transplantation and mechanical circulatory support, Rigshopsitalet Copenhagen University Hospital.

Still, he disputed the characterization by the investigators and indeed the published report that the patients, or most of them, had “end-stage heart failure.”

For example, about a third of the trial’s patients started out in NYHA class 2, Dr. Gustafsson noted. Not that they weren’t “high-risk” or their HF wasn’t severe, he offered, but they don’t seem to have been “a truly advanced heart failure population.”

The trial population consisted of “patients referred to an advanced heart failure center, rather than patients with advanced heart failure,” agreed Mandeep R. Mehra, MD, director of the Center for Advanced Heart Disease at Brigham and Woman’s Hospital, Boston.

Also citing a large prevalence of patients in NYHA class-2, Dr. Mehra added that “we almost never see paroxysmal atrial fib in these patients. It’s usually an early-stage phenomenon.” In advanced HF, AF “is usually permanent,” he told this news organization. Yet it was paroxysmal in about 30% of cases.

To its credit, Dr. Mehra observed, the study does assert that advanced HF is no reason, necessarily, to avoid catheter ablation. Nor should an AF patient’s referral to an advanced-HF center “mean that you should rush to an LVAD or transplant” before considering ablation.

The study seems to be saying, “please exhaust all options before you biologically replace the heart or put in an LVAD,” Dr. Mehra said. “Certainly, this paper steers you in that direction.”

The trial entered 194 patients with symptomatic AF and HF of at least NYHA class 2, with impaired functional capacity by the 6-minute walk test, who had been referred to a major center in Germany for a heart-transplantation workup. With all on guideline-directed medical therapy, 97 were randomly assigned open-label to catheter ablation and 97 to continued standard care.

Catheter ablation was actually carried out in 81 patients (84%) who had been assigned to it and in 16 (16%) of those in the control group, the report states.

A total of 8 in the ablation group and 29 in the control arm died, received an LVAD, or went to urgent transplantation, for a hazard ratio of 0.24 (95% confidence interval, 0.11-0.52; P < .001) for the primary endpoint.

Death from any cause apparently played a big role in the risk reduction; its HR was 0.29 (95% CI, 0.12-0.72).

One peculiarity of the data, Dr. Mehra said, is that event curves for the primary endpoint and its individual components “diverge almost from day 1.” That would mean the ablation group right away started having fewer deaths, LVAD placements, or heart transplants than the control group.

“It is surprising to see such a large effect size on endpoints that are very much dependent on operators and diverge within the first day.” Probably, Dr. Mehra said, “it has to do with this being a single-center study that may not be generalizable to other practices.”

CASTLE HTx was supported by a grant from Else Kröner-Fresenius-Stiftung. Dr. Sommer discloses consulting for Abbott, Biosense Webster, Boston Scientific, and Medtronic. Dr. Sohns reported no relevant financial relationships. Dr. Gustafsson discloses receiving honoraria or fees for consulting from Abbott, Alnylam Amgen, Boehringer Ingelheim, Ionis, Novartis, and Pfizer; serving on a speakers bureau for Astra Zeneca and Orion; and receiving grants from Corvia Research. Dr. Mehra has reported receiving payments to his institution from Abbott for consulting; consulting fees from Janssen, Mesoblast, Broadview Ventures, Natera, Paragonix, Moderna, and the Baim Institute for Clinical Research; and serving on a scientific advisory board for NuPulseCV, Leviticus, and FineHeart.

To its credit, Dr. Mehra observed, the study does assert that advanced HF is no reason, necessarily, to avoid catheter ablation. Nor should an AF patient’s referral to an advanced-HF center “mean that you should rush to an LVAD or transplant” before considering ablation.

The study seems to be saying, “please exhaust all options before you biologically replace the heart or put in an LVAD,” Dr. Mehra said. “Certainly, this paper steers you in that direction.”

The trial entered 194 patients with symptomatic AF and HF of at least NYHA class 2, with impaired functional capacity by the 6-minute walk test, who had been referred to a major center in Germany for a heart-transplantation workup. With all on guideline-directed medical therapy, 97 were randomly assigned open-label to catheter ablation and 97 to continued standard care.

Catheter ablation was actually carried out in 81 patients (84%) who had been assigned to it and in 16 (16%) of those in the control group, the report states.

A total of 8 in the ablation group and 29 in the control arm died, received an LVAD, or went to urgent transplantation, for a hazard ratio of 0.24 (95% confidence interval, 0.11-0.52; P < .001) for the primary endpoint.

Death from any cause apparently played a big role in the risk reduction; its HR was 0.29 (95% CI, 0.12-0.72).

One peculiarity of the data, Dr. Mehra said, is that event curves for the primary endpoint and its individual components “diverge almost from day 1.” That would mean the ablation group right away started having fewer deaths, LVAD placements, or heart transplants than the control group.

“It is surprising to see such a large effect size on endpoints that are very much dependent on operators and diverge within the first day.” Probably, Dr. Mehra said, “it has to do with this being a single-center study that may not be generalizable to other practices.”

AMSTERDAM – The more weight patients lost while on weekly semaglutide treatment in the STEP-HFpEF trial, the better their outcomes, suggesting that weight loss by itself was a major reason why the treatment improved a broad range of prespecified study outcomes, including symptoms and physical limitations, exercise capacity, and inflammation, new analyses from the trial show.

At the annual congress of the European Society of Cardiology where he presented these new findings, Mikhail N. Kosiborod, MD, also posited that weight loss produced by weekly subcutaneous injections of 2.4 mg semaglutide (Wegovy) for 52 weeks in the study does not fully explain the multiple mechanisms that may be involved in producing this intervention’s effects in the STEP-HFpEF trial.

His report earlier at the congress and in a simultaneously published report of the trial’s primary outcomes established a role for medically induced weight loss in managing patients with obesity-phenotype HFpEF in a total of 529 randomized individuals with HFpEF and obesity but without diabetes.

The new analyses showed that for one of the two primary endpoints – the change from baseline in patients’ assessment on the Kansas City Cardiomyopathy Questionnaire Clinical Summary Score (KCCQ), the placebo-adjusted average change was a 16.1-point improvement in the 51 people with a 5%-10% weight loss during the 1-year study, and a 21.6-point improvement in the 58 who had at least a 20% weight loss, a between-group average 5.5 point difference that represents a clinically meaningful incremental improvement in this validated metric of symptoms and functional limitations.

Similar weight-related differences in benefit also occurred for the secondary outcomes of changes from baseline in 6-minute walk distance and in levels of C-reactive protein (CRP), a measure of systemic inflammation.

In an adjusted regression model, every 10% drop from baseline body weight was significantly linked with a 6.4-point improvement in KCCQ score, a 14.4 meter improvement in 6-minute walk distance, and a 28% relative reduction from baseline in CRP, reported Dr. Kosiborod, a cardiologist and codirector of the Haverty Cardiometabolic Center of Excellence at Saint Luke’s Mid America Heart Institute in Kansas City, Mo.

These new, prespecified analyses also showed that people with obesity and HFpEF responded roughly the same to semaglutide treatment compared with placebo-treated controls regardless of their starting body mass index, including people with class 1 (30-34 kg/m²), class 2 (35-39 kg/m²), and class 3 (≥ 40 kg/m²) obesity.

Simultaneously with Dr. Kosiborod’s report at the congress, these findings appeared in a report posted online in Nature Medicine.
 

Not every benefit was fully mediated by weight loss

These analyses “do not tell us how much of the benefit was mediated by weight loss, but the data do say that the more weight a person lost, the more benefit they got,” Dr. Kosiborod explained in an interview. “That is not the same as saying that everything is mediated by weight. It doesn’t say that nothing beyond weight loss matters.”

He and his associates are planning a mediation analysis of data from STEP-HFpEF that will more directly address this issue.

“It’s likely that people who lost more weight with semaglutide also had greater benefits from other effects of semaglutide at the same time. Weight loss is a good surrogate marker” for the range of effects that a person receives from treatment with semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist, Dr. Kosiborod said.

“GLP-1 receptor agonists may have direct effects on atherosclerosis, as well as other effects that are uncoupled from weight loss,” such as proven anti-inflammatory effects, he added.

Another exploratory effect from semaglutide treatment in the study and reported by Dr. Kosiborod was a significant reduction in serum levels of N-terminal pro brain natriuretic peptide, an association never previously seen with weight loss in people with heart failure.

“The outcomes we’ve already seen in STEP-HFpEF were largely symptomatic, which are extraordinarily important, but there may be a completely different relationship between weight and clinical events,” said John E. Deanfield, PhD, a professor of cardiology at University College Hospital, London, who was not involved in the study.

Dr. Deanfield noted that important prognostic markers such as cholesterol levels and blood pressure reductions are usually not temporally related to weight loss. “The idea that [the benefits seen in STEP-HFpEF] are purely from weight loss is something we need to be careful about,” he said.

“My gut feeling is that at least 75% of the effect [in STEP-HFpEF} was due to weight loss,” said Naveed Sattar, PhD, professor of metabolic medicine at the University of Glasgow, who was not associated with the research.

AMSTERDAM – Intravenous iron supplementation showed modest benefits in recently hospitalized patients with heart failure and iron deficiency in the HEART-FID trial, but the study failed to meet the specified more rigorous definition of significance (P = .01) on the primary hierarchical composite of death, hospitalizations for heart failure, or 6-minute walk distance.

The trial, which investigated intravenous ferric carboxymaltose treatment vs. placebo, also showed no statistical difference in the main secondary endpoint: time to cardiovascular death or first heart failure hospitalization.

It was hoped that HEART-FID, the largest study to date to look at intravenous iron supplementation in heart failure, would confirm benefits suggested in previous smaller studies, but its modest results seem to have, if anything, caused more uncertainly on whether supplementing iron is actually worthwhile.

The HEART-FID trial was presented at the annual congress of the European Society of Cardiology and simultaneously published online in the New England Journal of Medicine.

Another presentation at the ESC Congress reported a pooled meta-analysis of all the intravenous iron supplementation studies, including HEART-FID. This showed a significant reduction in one coprimary endpoint (cardiovascular hospitalization/CV death) but not in the other (heart failure hospitalization/CV death), which is the more traditional and well-recognized endpoint in heart failure trials.

The meta-analysis was also published online in the European Heart Journal.

HEART-FID lead investigator, Robert J. Mentz, MD, Duke University, Durham, N.C., said the totality of the evidence showed clinical benefits of intravenous iron supplementation with intravenous ferric carboxymaltose.

“I worry that people will focus on a P value rather than the actual clinical benefits seen across all the studies,” Dr. Mentz said in an interview. “Technically, this study was neutral in respect to the primary endpoint, but when we look at all the evidence with respect to ferric carboxymaltose, including this new pooled analysis, this does support clinical benefits.”

Comoderator of the ESC Hotline session at which the trial was presented, John McMurray, MD, University of Glasgow (Scotland), thought the trial had “muddied the waters a bit” on the issue of iron supplementation in heart failure.

“I would say we are in a less clear position on iron supplementation now than we were a few months ago. Those clinicians who have believed that checking iron levels and supplementing iron in those who are low is the right thing to do may now be wondering about that,” he told this news organization.  

Dr. McMurray noted that initial impressions of the data from both HEART-FID and the meta-analysis suggested some benefit of intravenous iron on CV death/heart failure hospitalization in the first year, but on longer term follow-up, that benefit was less evident.

“We need to look further into why there is that discrepancy,” he said. “This could be a statistical phenomenon or could be something to do with the frequency of redosing over the longer term.”

He explained that several previous studies of intravenous iron supplementation in heart failure have reported apparent convincing benefits on quality of life and functional capacity, but there has been some uncertainty on this because of the difficulty in producing a placebo for intravenous iron.

“So, it would have been great to have some additional confirmation of these benefits and on harder endpoints,” he said, “but even in HEART-FID, there was only a small nonsignificant benefit in walking distance.”
 

HEART-FID

The HEART-FID trial randomly assigned 3,065 ambulatory patients with heart failure, a left ventricular ejection fraction of 40% or less, and iron deficiency to intravenous ferric carboxymaltose or placebo, given every 6 months as needed on the basis of iron indexes and hemoglobin levels, in addition to standard therapy for heart failure.

The primary outcome was a hierarchical composite of death within 12 months after randomization, hospitalizations for heart failure within 12 months after randomization, or change from baseline to 6 months in the 6-minute walk distance. The significance level was set at .01.

Results showed that death by month 12 occurred in 8.6% of the ferric carboxymaltose group and 10.3% of the placebo group; a total of 297 and 332 hospitalizations for heart failure, respectively, occurred by month 12; and the mean change from baseline to 6 months in the 6-minute walk distance was 8 meters in the ferric carboxymaltose group and 4 meters with placebo. The P value for the primary composite was .02.

The trial also used another method (unmatched win ratio) to analyze the hierarchical composite outcome in the ferric carboxymaltose group as compared with the placebo group that gave a result of 1.10 (99% confidence interval, 0.99-1.23).

During the follow-up period, CV death or hospitalization for heart failure (the main secondary outcome) occurred in 31.0% of the ferric carboxymaltose group and in 32.2% of the placebo group (hazard ratio, 0.93; 96% CI, 0.81-1.06).

Repeated dosing of ferric carboxymaltose appeared to be safe, with an acceptable adverse-event profile in most patients. The number of patients with serious adverse events occurring during the treatment period was similar in the two groups (27.0% in the ferric carboxymaltose group and 26.2% in the placebo group).
 

‘It’s hard to argue that we are not disappointed’

Designated discussant of the HEART-FID study at the ESC HOTLINE session, Scott Solomon, MD, Brigham and Women’s Hospital, Boston, described HEART-FID as “an extremely important and well-conducted trial.”

He noted that iron deficiency is extremely common in patients with heart failure, affecting at least about a third of patients, and is associated with reduced New York Heart Association class and reduced survival. Previous smaller studies have suggested benefit but have narrowly missed their primary endpoints. HEART-FID was a larger and sufficiently well-powered trial to test the hypothesis that iron supplementation can improve harder clinical endpoints.

Dr. Solomon said that the primary endpoint could be difficult to interpret, with a hierarchical composite, and a win ratio. “But I think it’s fair to say that the results are modest at best,” he added.

“When we look at the traditional cardiovascular death/heart failure hospitalization endpoint, one of the hard endpoints that we care about most in heart failure, it’s hard to argue that we are not disappointed,” he commented.

Referring to the P value of .01 threshold set for significance, which is based on new U.S. Food and Drug Administration regulatory standards, Dr. Solomon noted, “If they had used a standard P = .05 threshold, then they would be able to claim that this trial had met its primary endpoint. But, nevertheless, whatever threshold for significance we look at, the benefit was clearly modest.”

“As with all trials that show modest results, it will be useful to look at subgroups that are most likely to respond to the greatest extent to this therapy, and I look forward to learning more on this from further analyses,” Dr. Solomon concluded.

In an accompanying editorial in the New England Journal of Medicine, Pieter Martens, MD, and Wilfried Mullens, MD, PhD, Ziekenhuis Oost-Limburg, Genk, Belgium, and Hasselt (Belgium) University, point out that analyses from previous trials have suggested that intravenous iron did not have a treatment effect in patients with a transferrin saturation of more than 20%.

They note that, in the ferric carboxymaltose group in the HEART-FID trial, the mean transferrin saturation was 23.9% at baseline, higher than in previous studies.

Future analyses should assess the importance of the transferrin saturation value at baseline, which “could help redefine the definition of iron deficiency in patients with heart failure and, we hope, help clinicians determine which patients might benefit from intravenous iron supplementation,” they write.
 

Meta-analysis of trials

The meta-analysis of intravenous iron supplementation trials in heart failure was presented by Piotr Ponikowski, MD, Medical University Wroclaw (Poland).

The analysis pooled individual patient data from three double-blind, placebo-controlled trials – CONFIRM-HF 2, AFFIRM-AHF 3, and HEART-FID – giving a total of 4,475 patients, with 2,241 receiving ferric carboxymaltose and 2,234 receiving placebo.

The two prespecified composite primary endpoints were CV hospitalizations/CV death and heart failure hospitalizations/CV death.

These showed similar 13%-14% relative risk reductions with ferric carboxymaltose, but only the former was statistically significant.

Referring to the P value of .01 threshold set for significance, which is based on new U.S. Food and Drug Administration regulatory standards, Dr. Solomon noted, “If they had used a standard P = .05 threshold, then they would be able to claim that this trial had met its primary endpoint. But, nevertheless, whatever threshold for significance we look at, the benefit was clearly modest.”

“As with all trials that show modest results, it will be useful to look at subgroups that are most likely to respond to the greatest extent to this therapy, and I look forward to learning more on this from further analyses,” Dr. Solomon concluded.

In an accompanying editorial in the New England Journal of Medicine, Pieter Martens, MD, and Wilfried Mullens, MD, PhD, Ziekenhuis Oost-Limburg, Genk, Belgium, and Hasselt (Belgium) University, point out that analyses from previous trials have suggested that intravenous iron did not have a treatment effect in patients with a transferrin saturation of more than 20%.

They note that, in the ferric carboxymaltose group in the HEART-FID trial, the mean transferrin saturation was 23.9% at baseline, higher than in previous studies.

Future analyses should assess the importance of the transferrin saturation value at baseline, which “could help redefine the definition of iron deficiency in patients with heart failure and, we hope, help clinicians determine which patients might benefit from intravenous iron supplementation,” they write.
 

Meta-analysis of trials

The meta-analysis of intravenous iron supplementation trials in heart failure was presented by Piotr Ponikowski, MD, Medical University Wroclaw (Poland).

The analysis pooled individual patient data from three double-blind, placebo-controlled trials – CONFIRM-HF 2, AFFIRM-AHF 3, and HEART-FID – giving a total of 4,475 patients, with 2,241 receiving ferric carboxymaltose and 2,234 receiving placebo.

The two prespecified composite primary endpoints were CV hospitalizations/CV death and heart failure hospitalizations/CV death.

These showed similar 13%-14% relative risk reductions with ferric carboxymaltose, but only the former was statistically significant.

AMSTERDAM – Intravenous iron supplementation showed modest benefits in recently hospitalized patients with heart failure and iron deficiency in the HEART-FID trial, but the study failed to meet the specified more rigorous definition of significance (P = .01) on the primary hierarchical composite of death, hospitalizations for heart failure, or 6-minute walk distance.

The trial, which investigated intravenous ferric carboxymaltose treatment vs. placebo, also showed no statistical difference in the main secondary endpoint: time to cardiovascular death or first heart failure hospitalization.

It was hoped that HEART-FID, the largest study to date to look at intravenous iron supplementation in heart failure, would confirm benefits suggested in previous smaller studies, but its modest results seem to have, if anything, caused more uncertainly on whether supplementing iron is actually worthwhile.

The HEART-FID trial was presented at the annual congress of the European Society of Cardiology and simultaneously published online in the New England Journal of Medicine.

Another presentation at the ESC Congress reported a pooled meta-analysis of all the intravenous iron supplementation studies, including HEART-FID. This showed a significant reduction in one coprimary endpoint (cardiovascular hospitalization/CV death) but not in the other (heart failure hospitalization/CV death), which is the more traditional and well-recognized endpoint in heart failure trials.

The meta-analysis was also published online in the European Heart Journal.

HEART-FID lead investigator, Robert J. Mentz, MD, Duke University, Durham, N.C., said the totality of the evidence showed clinical benefits of intravenous iron supplementation with intravenous ferric carboxymaltose.

“I worry that people will focus on a P value rather than the actual clinical benefits seen across all the studies,” Dr. Mentz said in an interview. “Technically, this study was neutral in respect to the primary endpoint, but when we look at all the evidence with respect to ferric carboxymaltose, including this new pooled analysis, this does support clinical benefits.”

Comoderator of the ESC Hotline session at which the trial was presented, John McMurray, MD, University of Glasgow (Scotland), thought the trial had “muddied the waters a bit” on the issue of iron supplementation in heart failure.

“I would say we are in a less clear position on iron supplementation now than we were a few months ago. Those clinicians who have believed that checking iron levels and supplementing iron in those who are low is the right thing to do may now be wondering about that,” he told this news organization.  

Dr. McMurray noted that initial impressions of the data from both HEART-FID and the meta-analysis suggested some benefit of intravenous iron on CV death/heart failure hospitalization in the first year, but on longer term follow-up, that benefit was less evident.

“We need to look further into why there is that discrepancy,” he said. “This could be a statistical phenomenon or could be something to do with the frequency of redosing over the longer term.”

He explained that several previous studies of intravenous iron supplementation in heart failure have reported apparent convincing benefits on quality of life and functional capacity, but there has been some uncertainty on this because of the difficulty in producing a placebo for intravenous iron.

“So, it would have been great to have some additional confirmation of these benefits and on harder endpoints,” he said, “but even in HEART-FID, there was only a small nonsignificant benefit in walking distance.”
 

HEART-FID

The HEART-FID trial randomly assigned 3,065 ambulatory patients with heart failure, a left ventricular ejection fraction of 40% or less, and iron deficiency to intravenous ferric carboxymaltose or placebo, given every 6 months as needed on the basis of iron indexes and hemoglobin levels, in addition to standard therapy for heart failure.

The primary outcome was a hierarchical composite of death within 12 months after randomization, hospitalizations for heart failure within 12 months after randomization, or change from baseline to 6 months in the 6-minute walk distance. The significance level was set at .01.

Results showed that death by month 12 occurred in 8.6% of the ferric carboxymaltose group and 10.3% of the placebo group; a total of 297 and 332 hospitalizations for heart failure, respectively, occurred by month 12; and the mean change from baseline to 6 months in the 6-minute walk distance was 8 meters in the ferric carboxymaltose group and 4 meters with placebo. The P value for the primary composite was .02.

The trial also used another method (unmatched win ratio) to analyze the hierarchical composite outcome in the ferric carboxymaltose group as compared with the placebo group that gave a result of 1.10 (99% confidence interval, 0.99-1.23).

During the follow-up period, CV death or hospitalization for heart failure (the main secondary outcome) occurred in 31.0% of the ferric carboxymaltose group and in 32.2% of the placebo group (hazard ratio, 0.93; 96% CI, 0.81-1.06).

Repeated dosing of ferric carboxymaltose appeared to be safe, with an acceptable adverse-event profile in most patients. The number of patients with serious adverse events occurring during the treatment period was similar in the two groups (27.0% in the ferric carboxymaltose group and 26.2% in the placebo group).
 

‘It’s hard to argue that we are not disappointed’

Designated discussant of the HEART-FID study at the ESC HOTLINE session, Scott Solomon, MD, Brigham and Women’s Hospital, Boston, described HEART-FID as “an extremely important and well-conducted trial.”

He noted that iron deficiency is extremely common in patients with heart failure, affecting at least about a third of patients, and is associated with reduced New York Heart Association class and reduced survival. Previous smaller studies have suggested benefit but have narrowly missed their primary endpoints. HEART-FID was a larger and sufficiently well-powered trial to test the hypothesis that iron supplementation can improve harder clinical endpoints.

Dr. Solomon said that the primary endpoint could be difficult to interpret, with a hierarchical composite, and a win ratio. “But I think it’s fair to say that the results are modest at best,” he added.

“When we look at the traditional cardiovascular death/heart failure hospitalization endpoint, one of the hard endpoints that we care about most in heart failure, it’s hard to argue that we are not disappointed,” he commented.

When added to guideline-directed therapies for heart failure with reduced ejection fraction (HFrEF), a traditional Chinese medicine called qiliqiangxin reduced the composite endpoint of cardiovascular death and heart failure hospitalization by more than 20%, results of a large placebo-controlled trial show.

“The risk reductions in both cardiovascular death and heart failure hospitalization were substantial, clinically important, and consistent across all subgroups,” reported Xinli Li, MD, PhD, First Affiliated Hospital, Nanjing Medical University, China.

Qiliqiangxin, a commonly used therapy in China for cardiovascular disease, is not a single chemical entity but a treatment composed of 11 plant-based substances that together are associated with diuretic effects, vasodilation, and “cardiotonic” activity, Dr. Li said. He also cited studies showing an upregulation effect on peroxisome proliferator-activated receptor gamma coactivator 1-beta (PGC1-beta).

The results were presented at the annual congress of the European Society of Cardiology.
 

Hard endpoints pursued in rigorous design

There have been numerous studies of qiliqiangxin for cardiovascular diseases, including a double-blind study that associated this agent with a greater than 30% reduction in the surrogate endpoint of N-terminal pro–B-type natriuretic peptide (NT-proBNP).

In the newly completed multicenter trial, called QUEST, the goal was to determine whether this therapy could reduce hard endpoints relative to placebo in a rigorously conducted trial enrolling patients receiving an optimized triple-therapy heart failure regimen.

Few patients in the study received a sodium glucose cotransporter-2 (SGLT-2 inhibitor), which was not a standard at the time the study was designed but is now part of the quadruple guideline-directed medical therapy in most European and North American guidelines.

In this trial, 3,119 patients were randomly assigned at 133 centers in China to take four capsules of qiliqiangxin or placebo three times per day. At a median follow-up of 18.3 months, outcomes were evaluable in nearly all 1,561 patients randomly assigned to the experimental therapy and 1,555 patients randomly assigned to placebo.

The key inclusion criteria were a left ventricular ejection fraction of 40% or less and a serum NT-proBNP level of at least 450 pg/mL. Patients in New York Heart Association class IV heart failure were excluded.

At enrollment, more than 80% of patients in both arms were receiving a renin-angiotensin system (RAS) inhibitor (angiotensin-converting enzyme inhibitor, angiotensin receptor blocker, or angiotensin receptor neprilysin inhibitor), more than 80% were receiving a mineralocorticoid receptor antagonist, and more than 85% were receiving a beta-blocker.
 

Death and hospitalization reduced 22%

By hazard ratio, the primary composite endpoint of CV death and heart failure hospitalization was reduced by 22% relative to placebo (HR, 0.78; P < .001). When evaluated separately, the relative reductions in these respective endpoints were 17% (HR, 0.83; P = .045) and 24% (HR, 0.76; P = .002).

The risk reduction was robust (HR, 0.76; P < .001) in patients with an ischemic cause but nonsignificant in those without (HR, 0.92; P = .575). A significant benefit was sustained in patients receiving an angiotensin receptor neprilysin inhibitor (HR, 0.84; P = .041), as well as those who did not receive this class of drug (HR, 0.77; P = .012).

However, the benefit of qiliqiangxin among patients receiving all components of guideline-directed triple therapy (RAS inhibitor, beta-blocker, and mineralocorticoid antagonist) was only a trend (HR, 0.86; P = .079).

All-cause mortality, a secondary endpoint, was lower among patients randomly assigned to qiliqiangxin than to those assigned to placebo, but this difference fell just short of statistical significance (14.21% vs. 16.85%; P = .058).

Qiliqiangxin was well tolerated. The proportion of patients with a serious adverse event was numerically lower with qiliqiangxin than with placebo (17.43% vs. 19.74%), whereas discontinuations associated with an adverse event were numerically higher in the qiliqiangxin group (1.03% vs. 0.58%), albeit still very low in both study arms.
 

Overlap of drug benefits suspected

Given the safety of this drug and its highly significant reduction in a composite endpoint used in other major HFrEF trials, the ESC-invited discussant, Carolyn S.P. Lam, MBBS, PhD, National Heart Centre, Singapore, called the outcome “remarkable” and a validation for “the millions of people” who are already taking qiliqiangxin in China and other Asian countries.

Using the DAPA-HF trial as a point of reference, Dr. Lam noted that relative reduction in the composite endpoint of cardiovascular death for the SGLT-2 inhibitor dapagliflozin relative to placebo on top of triple guideline-directed medical therapy was lower (17% vs. 24%), but there were significant reductions in each of the components, as well as a nonsignificant signal of a mortality benefit.

However, Dr. Lam pointed out that there does seem to be more of an overlap for the benefits of qiliqiangxin than dapagliflozin relative to other components of triple therapy based on the lower rate of benefit when patients were optimized on triple therapy.

“The subgroup analysis [of this study] is very important,” Dr. Lam said. Qiliqiangxin may be best in patients who cannot take one or more of the components of triple therapy, she suggested, even though she called for further studies to test this theory. She also cautioned that the pill burden of four capsules taken three times per day might be onerous for some patients.

Of the many questions still to be answered, Dr. Lam noted that the low rate of enrollment for patients (< 10%) taking SGLT-2 inhibitors makes the contribution of qiliqiangxin unclear among those receiving the current standard of quadruple guideline-directed medical therapy.

She also suggested that it will be important to dissect the relative contribution of the different active ingredients of qiliqiangxin.

“This is not a purified compound that we are used to in Western medicine,” Dr. Lam said. While she praised the study as “scientifically rigorous” and indicated that the results support a clinical benefit from qiliqiangxin, she thinks an exploration of the mechanism or mechanisms of benefit is a next step in understanding where this therapy fits in HFrEF management.

AMSTERDAM – Adults with heart failure with preserved ejection fraction (HFpEF) but without diabetes showed significant improvements in their heart failure-related symptoms and physical limitations, exercise function, and weight loss when treated with a weight-reducing dose of semaglutide for 52 weeks, compared with placebo, in the randomized STEP-HFpEF trial.

The results, which also showed the treatment’s safety in these patients, “indicate that treatment with semaglutide is a valuable therapeutic approach in the management of patients with HFpEF and obesity,” Mikhail Kosiborod, MD, said at the annual congress of the European Society of Cardiology.

Mitchel L. Zoler/MDedge News

The findings establish semaglutide, a glucagonlike peptide–1 (GLP-1) receptor agonist, as a second class of medication with proven efficacy and safety for people with HFpEF, joining two agents also proven beneficial for people with HFpEF, dapagliflozin (Farxiga) and empagliflozin (Jardiance), both from the class of sodium-glucose cotransporter 2 (SGLT2) inhibitors.

When administered at the approved dose for weight loss of 2.4 mg, injected subcutaneously weekly for 52 weeks, semaglutide (Wegovy) produced an average 7.8-point incremental improvement in patients’ scores on the Kansas City Cardiomyopathy Questionnaire (KCCQ), a validated measure of symptoms and functional limitations, compared with controls who received placebo injections, as well as an average incremental weight loss from baseline, compared with placebo, of 10.7%. Both were significant effects, compared with placebo, and clinically meaningful benefits for the study’s two primary endpoints.

Simultaneously with Kosiborod’s report the results also appeared in a report posted online in the New England Journal of Medicine.
 

A ‘paradigm shift’ for medical weight loss in cardiology

The findings from this study with 529 randomized patients immediately propelled the weight loss formulation of semaglutide into the ranks of agents used to treat and prevent cardiovascular disease events. This evolution in the indications for semaglutide will be driven not only by the STEP-HFpEF results but also by findings from the SELECT trial, which tested the same semaglutide weight-loss dose in people with obesity, established cardiovascular disease, and had positive top-line results for prevention of major cardiovascular adverse events, according to a press release from Novo Nordisk on Aug. 8.

The STEP-HFpEF and SELECT results will trigger “a paradigm shift” for cardiologists, who will now need to consider prescribing a weight-loss medication to many of their patients, agents that until now were not part of the usual pharmacologic toolbox for cardiologists, said Dr. Kosiborod, a cardiologist and codirector of the Haverty Cardiometabolic Center of Excellence at Saint Luke’s Mid America Heart Institute in Kansas City, Mo. This shift will require education to bring the clinical cardiology community on board, he added in an interview.

Given that semaglutide administered at this dose already has a Food and Drug Administration–approved indication for weight loss in people with obesity or overweight plus at least one comorbidity, clinicians could immediately start using the treatment in people with obesity and HFpEF, said Dr. Kosiborod and other cardiologists.

Weekly semaglutide injections “could be considered a treatment option right now” for people with obesity and HFpEF, Dr. Kosiborod said during a press briefing.

Other experts agreed, especially because the STEP-HFpEF results confirmed that weight loss treatment with semaglutide was safe in this population.
 

‘A terrific win for patients’

The new findings are “a terrific win and game changer for patients with HFpEF,” commented Gregg C. Fonarow, MD, professor and cochief of cardiology at the University of California, Los Angeles, who was not involved with the study.

“The magnitude of improvement in the patient-reported health status scores are large and impressive. These data support clinical use of this agent for individuals with HFpEF with a body mass index of 30 kg/m², patients who already fall within existing indications,” Dr. Fonarow said in an interview.

“Given the improvements in clinical outcomes in the STEP-HFpEF and SELECT trials, cardiologists should be prescribing these medications to eligible patients without conditions,” he added. “The perception of [semaglutide] needs to shift and be viewed as a component of the comprehensive medical therapies provided to individuals with established cardiovascular disease or HFpEF who also have elevated body mass index to improve their clinical outcomes.”

Historically, cardiologists have had a concern that weight loss was potentially harmful in people with heart failure and that obesity was protective, a phenomenon known as the “obesity paradox,” but the STEP-HFpEF data help disprove that notion, commented Nancy K. Sweitzer, MD, PhD, a heart failure specialist and vice chair of clinical research in the department of medicine at Washington University in St. Louis, who also was not involved in the study.
 

No signal of an obesity paradox

“There’s been a concern in the heart failure community to use weight-loss strategies in people with heart failure because of this, but this evidence provides a lot of confidence that it’s safe to use this weight loss treatment. The results show that patients feel better and lose weight with no signal of harm,” Dr. Sweitzer said in an interview.

The “encouraging findings” for semaglutide in patients with HFpEF “potentially add a much needed extra option for these patients and provide another upstream treatment for patients with signs of this condition plus a high body mass index,” commented Yigal M. Pinto, MD, PhD, in an editorial that accompanied the published report.

“How these findings translate to hard end points remains to be established and will be important in determining the role of GLP-1 agonism,” wrote Dr. Pinto, a professor and heart failure specialist at Amsterdam University Medical Center.

But Dr. Kosiborod said that the improvement seen in the KCCQ score was itself an important benefit for patients. “Heart failure is defined clinically based on symptoms,” he noted, and results in prior studies documented that patients value improvements in symptoms and physical limitations even more than they value “hard endpoints” such as survival.

The new findings, which indicate that two different and expensive classes of medications are now standard of care for many people with HFpEF and obesity – the SGLT2 inhibitors and the GLP-1 receptor agonist semaglutide – also raise concerns over patient access and affordability, as many U.S. insurers have a history of requiring prior authorization, high copays, or coverage denials for these two medical classes.

But Dr. Sweitzer and Dr. Kosiborod both said that the insurance-coverage climate seems, in just the past couple of years or so, to have dramatically improved, although it’s still not ideal.
 

Prior authorization hoops have decreased

“We still have prior-authorization hoops to jump through, but I expect these will continue to decrease over time as evidence for clinical benefits [from weight loss] continues to accumulate,” said Dr. Sweitzer.

And “the SELECT data mean that cardiologists will need to become comfortable prescribing GLP-1 receptor agonists,” she added.

“It’s not okay for insurers to say we are not going to cover weight loss medications because it’s a cosmetic indication,” said Dr. Kosiborod. “Obesity appears to be very important in the pathogenesis and progression of heart failure, and if patients derive substantial benefit, they should have access to this treatment.”

The improvements in KCCQ score, as well as in several secondary and exploratory endpoints including a significant reduction in C-reactive protein (an indication of a potent anti-inflammatory effect), an average 20 m increase in 6-minute walk distance, a significant average drop in N-terminal pro-brain natriuretic peptide, and a drop in heart failure hospitalizations or urgent heart failure visits (although the trial was not powered to show differences in clinical events), “were the largest benefits in these outcomes we’ve seen,” compared with any other medical intervention in people with HFpEF, he noted.

“About 80% of U.S. patients with HFpEF have obesity or overweight,” Dr. Kosiborod noted. Using semaglutide on these patients “is an issue of access and insurance coverage. My hope is that these and other data will favorably change this.”

A related trial with a similar design, STEP-HFpEF DM, is still in progress and testing the same semaglutide treatment in adults with HFpEF, obesity, and type 2 diabetes, noted Dr. Kosiborod, who is also lead investigator for that study. He said those results will likely become available before the end of 2023.

The study was funded by Novo Nordisk, the company that markets semaglutide (Wegovy). Dr. Kosiborod has been a consultant and adviser to and has received honoraria from Novo Nordisk. He has also been a consultant to numerous other companies, received research grants from AstraZeneca, Boehringer Ingelheim, and Pfizer, honoraria from AstraZeneca, and is a stockholder in Artera Health and Saghmos Therapeutics. Dr. Fonarow has been a consultant to Abbott, Amgen, AstraZeneca, CHF Solutions, Cytokinetics, Edwards, Janssen, Medtronic, Merck, Novartis, and Regeneron. Dr. Sweitzer reported no relevant financial relationships.

AMSTERDAM – Adults with heart failure with preserved ejection fraction (HFpEF) but without diabetes showed significant improvements in their heart failure-related symptoms and physical limitations, exercise function, and weight loss when treated with a weight-reducing dose of semaglutide for 52 weeks, compared with placebo, in the randomized STEP-HFpEF trial.

The results, which also showed the treatment’s safety in these patients, “indicate that treatment with semaglutide is a valuable therapeutic approach in the management of patients with HFpEF and obesity,” Mikhail Kosiborod, MD, said at the annual congress of the European Society of Cardiology.

The findings establish semaglutide, a glucagonlike peptide–1 (GLP-1) receptor agonist, as a second class of medication with proven efficacy and safety for people with HFpEF, joining two agents also proven beneficial for people with HFpEF, dapagliflozin (Farxiga) and empagliflozin (Jardiance), both from the class of sodium-glucose cotransporter 2 (SGLT2) inhibitors.

When administered at the approved dose for weight loss of 2.4 mg, injected subcutaneously weekly for 52 weeks, semaglutide (Wegovy) produced an average 7.8-point incremental improvement in patients’ scores on the Kansas City Cardiomyopathy Questionnaire (KCCQ), a validated measure of symptoms and functional limitations, compared with controls who received placebo injections, as well as an average incremental weight loss from baseline, compared with placebo, of 10.7%. Both were significant effects, compared with placebo, and clinically meaningful benefits for the study’s two primary endpoints.

Simultaneously with Kosiborod’s report the results also appeared in a report posted online in the New England Journal of Medicine.
 

A ‘paradigm shift’ for medical weight loss in cardiology

The findings from this study with 529 randomized patients immediately propelled the weight loss formulation of semaglutide into the ranks of agents used to treat and prevent cardiovascular disease events. This evolution in the indications for semaglutide will be driven not only by the STEP-HFpEF results but also by findings from the SELECT trial, which tested the same semaglutide weight-loss dose in people with obesity, established cardiovascular disease, and had positive top-line results for prevention of major cardiovascular adverse events, according to a press release from Novo Nordisk on Aug. 8.

The STEP-HFpEF and SELECT results will trigger “a paradigm shift” for cardiologists, who will now need to consider prescribing a weight-loss medication to many of their patients, agents that until now were not part of the usual pharmacologic toolbox for cardiologists, said Dr. Kosiborod, a cardiologist and codirector of the Haverty Cardiometabolic Center of Excellence at Saint Luke’s Mid America Heart Institute in Kansas City, Mo. This shift will require education to bring the clinical cardiology community on board, he added in an interview.

Given that semaglutide administered at this dose already has a Food and Drug Administration–approved indication for weight loss in people with obesity or overweight plus at least one comorbidity, clinicians could immediately start using the treatment in people with obesity and HFpEF, said Dr. Kosiborod and other cardiologists.

Weekly semaglutide injections “could be considered a treatment option right now” for people with obesity and HFpEF, Dr. Kosiborod said during a press briefing.

Other experts agreed, especially because the STEP-HFpEF results confirmed that weight loss treatment with semaglutide was safe in this population.

In patients with heart failure, mid-upper arm circumference (MUAC) and arm muscle circumference (AMC) are more significantly associated with prognosis than guideline-recommended skeletal muscle mass index (SMI) or calf circumference (CC) measurements, research suggests.
 

In a single-center, retrospective study that included more than 800 patients, high MUAC (hazard ratio for combined events, 0.590) and high AMC (HR for combined events, 0.529) were associated with significantly better prognoses than low MUAC and low AMC.

The findings were “surprising,” Kentaro Kamiya, PT, PhD, and Shota Uchida, PT, PhD, of Kitasato University School of Allied Health Sciences in Kanagawa, Japan, said in an interview.

“These findings challenge the current recommendations found in sarcopenia guidelines,” they noted. The European Working Group on Sarcopenia in Older People and the Asian Working Group for Sarcopenia recommend SMI, as measured by bioelectrical impedance analysis (BIA), and CC as methods for screening skeletal muscle mass.

The study was published online in the Canadian Journal of Cardiology.
 

Arm measures prognostic

Sarcopenia, which is marked by a loss of skeletal muscle mass and strength, is associated with risks of adverse outcomes. Patients with heart failure have a high rate of sarcopenia, but assessing skeletal muscle mass in these patients is difficult because of the fluid retention they often have.

The investigators examined the association between skeletal muscle mass metrics, measured using bioelectrical impedance analysis, and anthropometric measures and prognosis in patients with heart failure.

SMI was calculated using the BIA by dividing appendicular skeletal muscle mass by height squared. MUAC and CC were measured to the nearest 1 mm using a plastic tape measure. AMC was calculated as follows: MUAC (cm) − (0.314 x triceps skinfold [TSF]). The TSF was measured to the nearest 2 mm with a skinfold caliper. The measuring spot for TSF was the same measuring spot for MUAC. MUAC, CC, and TSF were measured by trained physiotherapists or nurses.

The investigators identified 1,930 consecutive patients with heart failure who underwent cardiac rehabilitation during their hospitalization. They excluded from their analysis 1,013 patients who did not undergo a skeletal mass metrics evaluation and 48 who could not be followed up.

The analysis included 869 patients (median age, 73 years; 62% men). Patients were separated into three groups on the basis of the sex-specific tertiles of skeletal muscle mass. The study endpoint was all-cause death or readmission due to heart failure, and the median follow-up period was 1.24 years.

After the investigators adjusted the data for age, sex, New York Heart Association functional class III or IV, left ventricular ejection fraction (LVEF), ischemic etiology, prior heart failure, diabetes, chronic obstructive pulmonary disease, log-transformed B-type natriuretic peptide (BNP), and estimated glomerular filtration rate (eGFR), the high MUAC and high AMC groups were associated with significantly better prognoses than their respective low groups. By contrast, high SMI and high CC were not associated with better prognoses.

Subgroup analyses showed no interactions between MUAC and age, sex, LVEF, BNP, eGFR, prior heart failure, beta-blocker use, and angiotensin-converting enzyme inhibitor or angiotensin II receptor blocker use. However, diuretic agents significantly interacted with AMC (P = .03).

“These results support the use of MUAC and AMC to determine the risk stratification of sarcopenia and a poor prognosis in patients with heart failure and suggest that they may be useful in developing treatment strategies in patients with heart failure,” wrote the authors.

“When caring for patients with heart failure, it seems that the often overlooked and simple measure of arm circumference might carry significant prognostic value,” said Dr. Kamiya and Dr. Uchida. “So, as you cuff the arm for routine blood pressure measurement, it might be worthwhile to also pay attention to arm girth.”

Although the findings provide valuable insights, they should be approached with caution, Dr. Kamiya and Dr. Uchida added. “Before considering them practice-changing, further research is needed to validate these results in diverse patient cohorts.”
 

Prospective study needed

Commenting on the study for this news organization, Jonathan H. Whiteson, MD, vice chair of clinical operations and medical director of cardiac and pulmonary rehabilitation at NYU Langone Health’s Rusk Rehabilitation in New York, expressed concerns about the study methodology.

Methodologic weaknesses include the retrospective, observational nature of the study and the fact that incomplete data collection led to the exclusion of more than half of the potential participants, he said. In addition, “anthropometric measurements are prone to inter-rater error. It is not clear if the same or different researchers conducted these measurements.

“Furthermore, hospitalized patients may not be clinically stable when discharged,” said Dr. Whiteson. “It is recommended that biometrics for muscle mass and fluid retention be done when patients are at an optimized clinical state: that is, stabilized outpatients.”

For now, Dr. Whiteson concluded, the findings should be considered “interesting and suggestive of further study.” What’s needed is “a prospective study including all patients admitted with heart failure, but measurements done when the patient is stabilized as an outpatient.”

The study was partially supported by the Japan Society for the Promotion of Science KAKENHI. Dr. Kamiya, Dr. Uchida, and Dr. Whiteson reported no conflicts of interest.

The findings were “surprising,” Kentaro Kamiya, PT, PhD, and Shota Uchida, PT, PhD, of Kitasato University School of Allied Health Sciences in Kanagawa, Japan, said in an interview.

“These findings challenge the current recommendations found in sarcopenia guidelines,” they noted. The European Working Group on Sarcopenia in Older People and the Asian Working Group for Sarcopenia recommend SMI, as measured by bioelectrical impedance analysis (BIA), and CC as methods for screening skeletal muscle mass.

The study was published online in the Canadian Journal of Cardiology.
 

Arm measures prognostic

Sarcopenia, which is marked by a loss of skeletal muscle mass and strength, is associated with risks of adverse outcomes. Patients with heart failure have a high rate of sarcopenia, but assessing skeletal muscle mass in these patients is difficult because of the fluid retention they often have.

The investigators examined the association between skeletal muscle mass metrics, measured using bioelectrical impedance analysis, and anthropometric measures and prognosis in patients with heart failure.

SMI was calculated using the BIA by dividing appendicular skeletal muscle mass by height squared. MUAC and CC were measured to the nearest 1 mm using a plastic tape measure. AMC was calculated as follows: MUAC (cm) − (0.314 x triceps skinfold [TSF]). The TSF was measured to the nearest 2 mm with a skinfold caliper. The measuring spot for TSF was the same measuring spot for MUAC. MUAC, CC, and TSF were measured by trained physiotherapists or nurses.

The investigators identified 1,930 consecutive patients with heart failure who underwent cardiac rehabilitation during their hospitalization. They excluded from their analysis 1,013 patients who did not undergo a skeletal mass metrics evaluation and 48 who could not be followed up.

The analysis included 869 patients (median age, 73 years; 62% men). Patients were separated into three groups on the basis of the sex-specific tertiles of skeletal muscle mass. The study endpoint was all-cause death or readmission due to heart failure, and the median follow-up period was 1.24 years.

After the investigators adjusted the data for age, sex, New York Heart Association functional class III or IV, left ventricular ejection fraction (LVEF), ischemic etiology, prior heart failure, diabetes, chronic obstructive pulmonary disease, log-transformed B-type natriuretic peptide (BNP), and estimated glomerular filtration rate (eGFR), the high MUAC and high AMC groups were associated with significantly better prognoses than their respective low groups. By contrast, high SMI and high CC were not associated with better prognoses.

Subgroup analyses showed no interactions between MUAC and age, sex, LVEF, BNP, eGFR, prior heart failure, beta-blocker use, and angiotensin-converting enzyme inhibitor or angiotensin II receptor blocker use. However, diuretic agents significantly interacted with AMC (P = .03).

“These results support the use of MUAC and AMC to determine the risk stratification of sarcopenia and a poor prognosis in patients with heart failure and suggest that they may be useful in developing treatment strategies in patients with heart failure,” wrote the authors.

“When caring for patients with heart failure, it seems that the often overlooked and simple measure of arm circumference might carry significant prognostic value,” said Dr. Kamiya and Dr. Uchida. “So, as you cuff the arm for routine blood pressure measurement, it might be worthwhile to also pay attention to arm girth.”

Although the findings provide valuable insights, they should be approached with caution, Dr. Kamiya and Dr. Uchida added. “Before considering them practice-changing, further research is needed to validate these results in diverse patient cohorts.”
 

Prospective study needed

Commenting on the study for this news organization, Jonathan H. Whiteson, MD, vice chair of clinical operations and medical director of cardiac and pulmonary rehabilitation at NYU Langone Health’s Rusk Rehabilitation in New York, expressed concerns about the study methodology.

Methodologic weaknesses include the retrospective, observational nature of the study and the fact that incomplete data collection led to the exclusion of more than half of the potential participants, he said. In addition, “anthropometric measurements are prone to inter-rater error. It is not clear if the same or different researchers conducted these measurements.

“Furthermore, hospitalized patients may not be clinically stable when discharged,” said Dr. Whiteson. “It is recommended that biometrics for muscle mass and fluid retention be done when patients are at an optimized clinical state: that is, stabilized outpatients.”

For now, Dr. Whiteson concluded, the findings should be considered “interesting and suggestive of further study.” What’s needed is “a prospective study including all patients admitted with heart failure, but measurements done when the patient is stabilized as an outpatient.”

The study was partially supported by the Japan Society for the Promotion of Science KAKENHI. Dr. Kamiya, Dr. Uchida, and Dr. Whiteson reported no conflicts of interest.

Datascope/Maquet/Getinge has announced a recall of the Cardiosave Hybrid and Rescue Intra-Aortic Balloon Pumps (IABPs) because they may shut down unexpectedly due to electrical failures in the power management board or solenoid board (power source path).

“Using an affected pump may cause serious adverse health events, including unstable blood pressure, injury (e.g., inadequate blood supply or a vital organ injury), and death,” the Food and Drug Administration said in the recall notice.

The FDA has identified this as a class I recall, the most serious type of recall due to the risk for serious injury or death. To date, Datascope/Maquet/Getinge received 26 complaints, but no reports of injuries or death.

The devices are indicated for acute coronary syndrome, cardiac and noncardiac surgery, and complications of heart failure in adults.

The recall includes a total of 4,586 Cardiosave Hybrid or Rescue IABP units distributed from March 2, 2012, to May 19, 2023. Product model numbers for the recalled Cardiosave Hybrid and Cardiosave Rescue are available online.

On June 5, Datascope/Maquet/Getinge sent an “important medical device advisory” to all affected customers. The letter advises customers to be sure there is an alternative IABP available to continue therapy and provide alternative hemodynamic support if there is no other means to continue counterpulsation therapy.

Customers with questions about this recall should contact their company representative or call technical support at 1-888-943-8872, Monday through Friday, between 8:00 a.m. and 6:00 p.m. ET.

Last March, Datascope/Getinge recalled 2,300 Cardiosave Hybrid or Rescue IABPs because the coiled cable connecting the display and base on some units may fail, causing an unexpected shutdown without warnings or alarms to alert the user.

The Cardiosave IABPs have also been previously flagged by the FDA for subpar battery performance and fluid leaks.

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