Tirzepatide for Heart Failure with Preserved Ejection Fraction and Obesity
Authors' conclusion
Treatment with tirzepatide led to a lower risk of a composite of death from cardiovascular causes or worsening heart failure than placebo and improved health status in patients with heart failure with preserved ejection fraction and obesity.
Study context
- Population
- Patients with HF, EF ≥50% and BMI ≥30 (HFpEF and obesity)
- Participants
- 731 patients
- Comparison
- Tirzepatide vs placebo
- Tirzepatiden = 364
- Placebon = 367reference
- Primary endpoint
- Two primary end points: composite of adjudicated CV death or worsening HF event (time-to-first-event); change in Kansas City Cardiomyopathy Questionnaire clinical summary score (KCCQ-CSS) (0–100, higher = better)
- Follow-up
- KCCQ-CSS: baseline to 52 weeks; median 104 weeks
Methodological detailsinternational, double-blind, placebo-controlled
