ABSTRACT
For the evaluation of the left ventricular diastolic function in mild to moderate hypertensive patients without left ventricular hypertrophy, 15 hypertensive patients (group A) and 15 normotensive subjects (group B) were examined by 2-D guided M-mode echocardiography. Various systolic and diastolic indices were derived from computer-assissted analysis of differential curves of left ventricular dimension and posterior wall thickness. The systolic and diastolic function indices of each of the two groups were compared. The results were as follows 1) There were no significant differences in ejection fraction, left ventricular peak ejection rate and posterior wall thickening rate between two groups. 2) There were no significant differences in % ventricular A wave, left ventricular peak filling rate and posterior wall peak relaxation rate between two groups. 3) One third filling rate was 2.07+/-0.41 EDD/sec in group A and which was significantly lower than 3.29+/-0.88 EDD/sec of group B. Above result suggests that computer-assisted analysis of differential curves of left ventricular dimension and posterior wall thickness could be helpful in the early detection of diastolic dysfunction, and that left ventricular diastolic dysfunction in its early filling period may develop in the mild to moderate hypertensive patients even before left ventricular hypertrophy develops.
