Understanding the Summit Trial's Focus
The Summit Trial investigates the effects of trisepatide on patients with heart failure with preserved ejection fraction (HFPEF) and obesity. The trial specifically targets individuals 40 years and older with a BMI of 30 or higher, aiming to determine if this dual-action GLP-1 and GIP agonist can effectively delay cardiovascular death or worsening heart failure events. It emphasizes that obesity and HFPEF frequently coexist, with 60-70% of HFPEF patients having a BMI over 30. The significance of understanding this overlap lies in its potential to refine treatment strategies, as these patients often present with unique challenges in management.
