  • Secondary analysis of the FINEARTS-HF randomised trial
  • subgroup analysis by baseline body mass index (BMI)

Authors' conclusion

In patients with HF with mildly reduced/preserved ejection fraction, the beneficial effects of finerenone on clinical events and symptoms were consistent, irrespective of BMI at baseline, possibly with a greater effect on the primary outcome in patients with higher BMI.

Study context

Population
Heart failure (HF), NYHA II–IV, LVEF ≥40%, structural heart disease and elevated natriuretic peptides; BMI by WHO categoriesBMI available for 5,988
Participants
6,001 participants
Comparison
Finerenone vs placebo by baseline BMI category
Primary endpoint
CV death and total worsening HF events

As reported in the abstract

CV death and total worsening HF events, finerenone vs placebo by baseline BMI
Finerenone vs PlaceboRate ratio (95% CI)
underweight/normal weight (<25.0 kg/m²; n = 1,306)

overweight (25.0-29.9 kg/m²; n = 1,990)

Effect did not vary by baseline BMI category
P for interaction = 0.32
BMI as continuous variable: greater benefit with higher BMI
P for interaction = 0.005
