  1. Values are mean ± SD; HTN: hypertension; E Dia: early diastole; A Dia: atrial diastole; MA: mitral annulus; Circ.: circumferential; Long.: longitudinal; * = significantly different from Control; †, the statistical significance retains after adjusting for age effect. Peak early and atrial filling rates were normalized to end-diastolic volume. Peak early and atrial diastolic MA velocity were normalized to left ventricular length multiplied by 100.
