Study was performed in 64 patients with hypertension who were treated at Viet Tiep Hospital, Hai Phong city from 2001 to 2002. The control group consisted of 36 normal healthy persons. Results: in patients with hypertension, the LA, Dd, IVSd, LWPd, LVMl increased more highly than in the control group. However, the evaluated parameters of the left ventricular function such as EF%, FS%, T%, lVS, T% LWP, the distance of E-lVS and curve EF of the heart valve decreased more than the normal persons. Only 15.62% of patients with hypertension had the left ventricular function decreased (EF<55%). While 90.62% of those patients had left ventricular function disorders. Reduced elastic ability of left ventricular occurred in majority of patients with hypertension (93.75%). The type of “unnormal” disorder of diastolic function occurred in 2 patients (3.12%)
