Epicardial Fat in Heart Failure with Preserved Ejection Fraction Compared with Reduced Ejection Fraction.

The role of epicardial adipose tissue (EAT) in heart failure with preserved ejection fraction (HFpEF) remains to be defined. A consecutive series of outpatients with chronic heart failure-heart failure with reduced ejection fraction (HFrEF) and HFpEF and/or diastolic dysfunction-had EAT assessed by echocardiographic measurement and related to indices of cardiac structure and function. Epicardial fat thickness was significantly ( < 0.
