Abstract:
To analyse the rate of changes of left atrial demension in ventricular diastole in hypertensive heart disease, the velocities of early diastolic(OR) slope and presystolic(AV) slope of the motions of the posterior aortic wall were measured using M-mode echocardiogram. 18 normal subjects(Group I), 17 hypertensive patients without left ventricular thickening(Group II), 16 hypertensive patients with thickening of either interventricular septum or left ventricular posterior wall(Group III), 15 hypertensive patients with both interventricular septum and left ventricular posterior wall without dilation of left ventricle(Group IV) and 5 hypertensive patients with thickening and dilation of left ventricle(Group V) were compared. Whereas %fractional shortening and AV slope decreased in only Group V, there was a progressive increase in left atrial dimension and a progressive decrease in the OR slope and patients without left atrial dilation in Group I also decrease in OR slope. The velocity of OR slope was correlated strongly with the thickness of left ventricular posterior wall(r=-0.62, p<0.001), and weakly with left atrial dimension(r=0.379, p<0.01) but not with heart rate and %fractional shortening and the velocity of AV slope with %fractional shortening(r=0.433, p<0.001). These data suggest that the velocity of OR slope appears to be an early indicator of abnormalities of left ventricular diastolic compliance and the velocity of AV slope and indicator of systolic abnormality and rapid filling of the left ventricle is reduced early in hypertension, even before left atrial dilation or left ventricular thickening are detectable.
