Semaglutide versus placebo in patients with heart failure and mildly reduced or preserved ejection fraction: a pooled analysis of the SELECT, FLOW, STEP-HFpEF, and STEP-HFpEF DM randomised trials

LancetPublished

  • Pooled participant-level analysis of randomised trials
  • post-hoc
  • placebo-controlled
  • 4 RCTs (SELECT, FLOW, STEP-HFpEF, STEP-HFpEF DM)

Authors' conclusion

In patients with HFpEF, semaglutide reduced the risk of the combined endpoint of cardiovascular death or worsening heart failure events, and worsening heart failure events alone, whereas its effect on cardiovascular death alone was not significant.
