Abstract

[BACKGROUND] More women than men have heart failure with preserved ejection fraction (HFpEF). [OBJECTIVES] The purpose of this study was to assess baseline characteristics and treatment effect of semaglutide by sex across the STEP-HFpEF (Research Study to Investigate How Well Semaglutide Works in People Living With Heart Failure and Obesity) program. [METHODS] In a prespecified secondary analysis of pooled data from STEP-HFpEF and STEP-HFpEF DM (Research Study to Look at How Well Semaglutide Works in People Living With Heart Failure, Obesity and Type 2 Diabetes), patients with heart failure (HF), left ventricular ejection fraction ≥45%, body mass index ≥30 kg/m2, and Kansas City Cardiomyopathy Questionnaire Clinical Summary Score (KCCQ-CSS) <90 points were randomized 1:1 to once-weekly semaglutide 2.4 mg or matched placebo for 52 weeks. Dual primary endpoints (KCCQ-CSS change and percentage change in body weight) and confirmatory secondary endpoints (6-minute walking distance [6MWD] change; hierarchical composite endpoint comprising all-cause death, HF events, changes in KCCQ-CSS, and 6MWD; and C-reactive protein) were compared between sexes. [RESULTS] Of 1,145 patients, 570 (49.7%) were women. Women had higher body mass index, left ventricular ejection fraction, C-reactive protein, and worse HF symptoms, and were less likely to have atrial fibrillation or coronary artery disease vs men. Semaglutide improved KCCQ-CSS regardless of sex (mean difference in women +7.6 points [95% CI: 4.5-10.7 points]; men +7.5 points [95% CI: 4.3-10.6 points]; P interaction = 0.94) but reduced body weight more in women (mean difference in women -9.6% [95% CI: -10.9% to -8.4%]; men -7.2% [95% CI: -8.4% to -6.0%]; P interaction = 0.006). Semaglutide improved 6MWD (P interaction = 0.21) and the hierarchical composite endpoint (P interaction = 0.66) in both sexes. Fewer serious adverse events were reported with semaglutide vs placebo. [CONCLUSIONS] In patients with obesity-related HFpEF, semaglutide 2.4 mg reduced body weight to a greater extent in women, and produced similar improvements in HF-related symptoms, physical limitations, and exercise function, regardless of sex.
