Authors' conclusion

In FINEARTS-HF, finerenone reduced the risk of total worsening HF events and cardiovascular death, and it improved symptoms; these effects were not modified by frailty status.

Study context

Population
Patients with heart failure (HF), NYHA class II–IV, LVEF ≥40%, structural heart disease and elevated natriuretic peptides (HFmrEF or HF and preserved ejection fraction (HFpEF))Frailty index (FI) calculable
Participants
5,952 patients
Comparison
Finerenone vs placebo, by frailty class
Primary endpoint
Composite of:
  • CV death
  • Total worsening HF events

Primary result

As reported in the abstract

Primary outcome, finerenone vs placebo, by frailty class (Rockwood FI)
Finerenone vs PlaceboRelative risk (95% CI)
class I frailty (FI ≤0.210), n = 1588
1.07(0.77–1.49)
class II frailty (FI 0.211-0.310), n = 2141
0.66(0.52–0.83)
class III frailty (FI ≥0.311), n = 2223
0.91(0.76–1.07)

Further findings

Outcomeunadjusted RR (95% CI)
Primary outcome risk by frailty class (vs class I) — Class II frailty vs Class I frailty1.88 (1.54–2.28)
Primary outcome risk by frailty class (vs class I) — Class III frailty vs Class I frailty3.86 (3.22–4.64)

Components of primary outcome, all-cause death, KCCQ total symptom score improvement

Frailty class did not modify the effects of finerenone

Safety

Hypotension, elevated creatinine, hyperkalemia, hypokalemia

Effects of finerenone vs placebo did not differ by frailty class
