Abstract

The HFpEF-ABA score is a simple diagnostic tool developed to estimate the probability of heart failure with preserved ejection fraction (HFpEF) using age, body mass index, and history of atrial fibrillation.
This study aims to evaluate the HFpEF-ABA score in patients with confirmed heart failure (HF) in the FINEARTS-HF trial, its prognostic implications, and the effect of finerenone treatment according to the HFpEF-ABA score.
FINEARTS-HF was a randomized, placebo-controlled trial enrolling patients with HF with a left ventricular ejection fraction ≥40%. HFpEF-ABA scores (as a probability between 0% and 100%) were calculated at baseline and categorized as <75%, 75%-90%, or >90%. The association between HFpEF-ABA score and clinical outcomes was examined as well as the effect of finerenone across the range of HFpEF-ABA scores.
Among 5,988 patients with available HFpEF-ABA scores, 1,940 (32.4%) had a score <75% (low probability), 1,241 (20.7%) had a score 75%-90% (intermediate probability), and 2,807 (46.9%) had a score >90% (high probability). Rates of HF outcomes were higher in patients with higher HFpEF-ABA scores. Examination of HFpEF-ABA score as a continuous variable showed a strikingly nonlinear association with outcomes; the rate of events was similar up to a score of ∼75%, above which there was a steep increase in the event rate. Finerenone reduced events consistently across HFpEF-ABA scores.
Despite a proven diagnosis of HF with mildly reduced ejection fraction/HFpEF, one-third of participants in FINEARTS-HF had an HFpEF-ABA score <75%, yet the therapeutic effect of finerenone was consistent across the range of HFpEF-ABA scores included. Higher HFpEF-ABA scores were associated with a greater risk of HF events.
