Objectives: The objective of this study is to investigate the distribution and determinants of diastolic function in a middle-aged cohort of African Americans (AA).
Background: The distribution and determinants of left ventricular (LV) diastolic function in AA are not well-described despite high rates of AA with diastolic heart failure and a five-fold higher risk of death in those with diastolic dysfunction (DD) compared to normal diastolic function.
Methods: Four categories of diastolic function were defined in JHS participants undergoing echocardiograms at the first examination (2001-2004) using mitral and pulmonary vein velocities.
