Tirzepatide improves cardiovascular outcomes in patients with heart failure with preserved ejection fraction (HFpEF) and obesity, reducing heart failure hospitalizations and improving quality of life.

For patients with obesity and heart failure with preserved ejection fraction (HFpEF), tirzepatide (15 mg weekly) has been shown to significantly reduce the risk of heart failure hospitalizations and cardiovascular death. It also improves heart structure and quality of life. This makes it a valuable option for this specific population, in addition to its benefits for diabetes and weight loss.

GoodSupportsHIGH confidence
The primary endpoint (a composite of cardiovascular death or heart failure hospitalization) was significantly reduced: 9.9% of tirzepatide patients vs 15.3% of placebo patients had an event. This ~38% relative risk reduction was mostly driven by fewer heart failure hospitalizations (8.0% vs 14.2%).

Why this rating

Based on the SUMMIT trial (Phase 3 RCT), but long-term mortality data is still pending (SURPASS-CVOT).
