Tirzepatide’s effectiveness in patients with heart failure and preserved pumping function

AI simplified

Abstract

Tirzepatide use was associated with a 52% lower risk of heart failure exacerbation and all-cause mortality in patients with heart failure with preserved ejection fraction.

  • In a cohort of 14,154 patients with heart failure with preserved ejection fraction, tirzepatide was linked to improved outcomes.
  • The primary composite outcome showed a hazard ratio of 0.52 for heart failure exacerbation and all-cause mortality.
  • Significantly lower risks were also observed for major adverse cardiovascular events ( 0.64) and major adverse kidney events (HR 0.44).
  • Subgroup analyses indicated consistent benefits across different patient groups.
  • Sensitivity analyses validated the reliability of these findings.
