  • Secondary analysis of a randomised controlled trial
  • double-blind
  • placebo-controlled

Authors' conclusion

Tirzepatide produced a comprehensive, meaningful improvement in heart failure across multiple complementary domains; enhanced health status, quality of life, functional capacity, exercise tolerance, and well-being; and reduced symptoms and medication burden in patients with heart failure with preserved ejection fraction and obesity.
