Semaglutide(Dr. Reddy)

Heart failure with preserved ejection fraction (HFpEF) is increasingly prevalent among individuals with obesity, primarily due to metabolic dysfunction and structural cardiac remodeling. This review explores the emerging therapeutic role of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) in managing HFpEF in obese populations.

Recent clinical trials, including the STEP-HFpEF and SUMMIT studies, have shown that GLP-1 RAs such as semaglutide and tirzepatide significantly reduce body weight (13.3% and 13.9%, respectively), enhance exercise capacity (increases of 21.5m and 26m in 6-minute walk distance), and improve quality of life (19.5 and 16.6-point increases in KCCQ-CSS scores). Additionally, both agents demonstrated marked reductions in systemic inflammation, with C-reactive protein levels decreasing by 38.8% and 43.5%, respectively. GLP-1 RAs represent a promising class of agents targeting the cardiometabolic axis in HFpEF, offering meaningful improvements in functional capacity and symptom burden among obese patients. However, current evidence is limited by short trial durations, lack of population diversity, and insufficient long-term data. Future research should focus on more inclusive cohorts and extended outcomes such as hospitalization rates and cardiovascular events to fully define the long-term safety and efficacy of GLP-1 RAs in HFpEF management.
