Mean and median LVEF were 53 ± 8% and 53% (IQR 46% -58%), respectively. LVEF was <50% in 2172 (36), between 50 to <60% in 2674 (45%), and ≥60% in 1147 (19%). Patients with a higher LVEF were older, more commonly female, were less likely to have a history of coronary artery disease, and more frequently had a history of hypertension and chronic kidney disease compared to those with a lower LVEF. Finerenone reduced the risk of cardiovascular death and total heart failure events consistently across LVEF categories: LVEF <50% rate ratio (RR) = 0.84 (95% CI 0.68, 1.03), LVEF ≥50 to <60% RR = 0.80 (0.66, 0.97) and LVEF ≥60% RR = 0.94 (0.70, 1.25); p interaction = 0.70. There was no modification of the benefit of finerenone across the range of LVEF when analyzed as a continuous variable (p interaction = 0.28). There was a similar consistent effect of finerenone on reducing the total number of worsening heart failure events (continuous p interaction = 0.26).</p><p><strong>Conclusions: </strong>In patients with HFmrEF/HFpEF, finerenone reduced the risk of cardiovascular death and worsening heart failure events, irrespective of LVEF.</p>","PeriodicalId":10331,"journal":{"name":"Circulation","volume":null,"pages":null},"PeriodicalIF":35.5,"publicationDate":"2024-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142342768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
