摘要

Accelerated biological aging (BA) is linked to adverse cardiovascular events, but its role in heart failure with preserved ejection fraction (HFpEF) remains unclear. We analyzed 1,727 HFpEF patients from RED-CARPET Study (ChiCTR2000039901), assessing BA using Klemera-Doubal and PhenoAge methods. During a median 4.9-year follow-up, 321 all-cause and 180 cardiovascular deaths occurred. After full adjustment, per 1-SD increase in BA acceleration showed significantly higher risk of all-cause mortality (KDMAge HR 1.55, 95% CI 1.40-1.72; PhenoAge HR 1.24, 95% CI 1.11-1.40) and cardiovascular mortality (KDMAge HR 1.47, 95% CI 1.28-1.69; PhenoAge HR 1.21, 95% CI 1.04-1.41). BA acceleration was also significantly related to increased left ventricular mass index (LVMI), relative wall thickness, and E/e’ ratio. Mediation analysis revealed that both LVMI and the E/e’ ratio partially mediated the relationship between BA acceleration and mortality. These findings suggest BA acceleration may serve as a key prognostic marker in patients with HFpEF.
