Predictors of new-onset heart failure: differences in preserved versus reduced ejection fraction.

ABSTRACT:

Background

About one half of patients with heart failure (HF) have preserved ejection fraction (HFPEF) rather than reduced ejection fraction (HFREF). The differences in risk factors predisposing to the 2 subtypes of HF are poorly understood. We sought to identify clinical predictors of new-onset HF and to explore differences in HFPEF versus HFREF.

Methods and results

We studied new-onset HF cases between 1981 and 2008 in Framingham Heart Study participants, classified into HFPEF and HFREF (ejection fraction >45% versus ≤45%). We used Cox multivariable regression to examine predictors of 8-year risk of incident HF and competing-risks analysis to identify predictors that differed between HFPEF and HFREF. Among 6340 participants (60±12 years) with 97 808 person-years of follow-
