Efficacy and safety of semaglutide in patients with heart failure with preserved ejection fraction and obesity.

Background: Semaglutide, a once-weekly glucagon-like peptide-1 receptor agonist, has shown promise in weight management and cardiovascular outcomes in other populations. This study aimed to evaluate the efficacy of semaglutide in heart failure with preserved ejection fraction (HFpEF) patients with obesity.

Methods: A retrospective study analyzed 318 patients with HFpEF, of which 104 received semaglutide and 214 received placebo. Primary endpoints included evaluating changes in exercise capacity and weight management.

Results: Semaglutide treatment led to significant improvements in the primary endpoints. Patients in the semaglutide group demonstrated substantial enhancements in exercise capacity, as measured by the 6-min walk distance, compared to the placebo group (mean difference 15.1 meters, 95% CI 5.8 to 24.4, p = 0.002). Additionally, semaglutide resulted in substantial weight loss compared to placebo (mean difference -2.9%, 95% CI -4.1--1.7, p = 0.001). Several secondary endpoints, including reductions in C-reactive protein levels and improvements in other clinical parameters, further supported the efficacy of semaglutide. Adverse events were generally well-tolerated, with no unexpected safety concerns.

Conclusion: Semaglutide demonstrated significant clinical benefits in HFpEF patients with obesity, as evidenced by improved symptoms, physical function, and weight reduction.
