History of Atrial Fibrillation as a Risk Factor in Patients With Heart Failure and Preserved Ejection Fraction

BACKGROUND: Atrial fibrillation (AFib) is common in heart failure (HF) with preserved ejection fraction (HFpEF). Current AFib stroke risk prediction models include the presence of HF but do not specifically include HFpEF as a risk factor. Whether a history of AFib should be used to identify patients with HFpEF who are at risk has not been established. METHODS AND RESULTS: Baseline characteristics and outcomes of patients with HFpEF in the …
