What are the safety and efficacy of finerenone in patients with heart failure with mildly reduced or preserved ejection fraction (HFmrEF/HFpEF) receiving background diuretics?In this prespecified secondary analysis of patients with HFmrEF/HFpEF in the FINEARTS-HF randomized clinical trial, the efficacy and safety of finerenone were consistent across subgroups defined by diuretic use, including those receiving only loop diuretics (≤40 mg and >40 mg of furosemide equivalent), only nonloop diuretics, and a combination of both. Finerenone reduced the need for loop diuretic dose intensification and decreased the mean loop diuretic dose compared to placebo.These findings demonstrate a diuretic-sparing effect of finerenone in patients with HFmrEF/HFpEF.
