Heart failure with preserved ejection fraction in African Americans: The ARIC (Atherosclerosis Risk In Communities) study

In an entirely African-American cohort, we compared clinical characteristics, cardiac structure and function, and all-cause mortality in patients with heart failure (HF) with preserved ejection fraction (HFpEF) in relation to patients with heart failure with reduced ejection fraction (HFrEF) and those without HF. African Americans are at increased risk for HF. Nevertheless, there are limited phenotypic and prognostic data in African Americans with HFpEF compared with those with HFrEF and those without HF. Middle-aged African Americans from the Jackson, Mississippi, cohort of the ARIC (Atherosclerosis Risk In Communities) study (n = 2,445) underwent echocardiography between 1993 and 1995. HF prevalence was available in 1,962 patients for whom left ventricular ejection fraction (LVEF) could be quantified. Participants with HF were categorized as having HFpEF (LVEF ≥50%), HFrEF (LVEF
