Effects of Semaglutide in Obesity-Related Heart Failure with Preserved Ejection Fraction Across the Age Spectrum: Findings from the STEP-HFpEF Programme

Eur J Heart FailPublished

  • Secondary analysis of the STEP-HFpEF and STEP-HFpEF DM randomised trials
  • pre-specified pooled subanalysis

Authors' conclusion

In patients with HFpEF enrolled across the STEP-HFpEF and STEP-HFpEF DM trials, treatment with semaglutide improved disease-specific symptoms, physical function and reduced body weight across the age spectrum. The safety profile of semaglutide was consistent in older and younger patients.

Study context

Population
Obesity-related heart failure with preserved ejection fraction (HFpEF), by age (<55, 55–64, 65–74, ≥75 years)
Participants
573 vs 572
Comparison
Semaglutide vs placebo across age groups
  • Semaglutiden = 573
  • Placebon = 572reference
Primary endpoint
Dual primary: change in KCCQ-CSS and change in body weight, across age groups
Follow-up
52 weeks

Primary result

As reported in the abstract

Dual primary endpoints across age groups

Semaglutide efficacy on KCCQ-CSS consistent across the age spectrum

p-interaction = 0.80

Semaglutide efficacy on body weight consistent across the age spectrum

p-interaction = 0.41

Secondary outcomes

Key secondary endpoints (6MWD, C-reactive protein, hierarchical composite) across age groups

Similar benefits, no treatment effect heterogeneity across age groups
