Prognostic Impact of Cardiac Diastolic Function and Coronary Microvascular Function on Cardiovascular Death.

ABSTRACT: Background Coronary microvascular dysfunction (CMD) has been considered as a possible cause of cardiac diastolic dysfunction. The current study evaluated the association between cardiac diastolic dysfunction and CMD, and their prognostic implications in patients without significant left ventricular systolic dysfunction and epicardial coronary stenosis. Methods and Results A total of 330 patients without left ventricular systolic dysfunction (ejection fraction ≥50%) and significant epicardial coronary stenosis (fractional flow reserve >0.80) were analyzed. Cardiac diastolic dysfunction was defined by echocardiographic parameters (early diastolic transmitral flow velocity/early diastolic mitral annular velocity, e' velocity, tricuspid regurgitation velocity, and left atrial volume index).
