Correlations between M-mode markers of left ventricular hypertrophy and radionuclide angiographic indices of left ventricular diastolic function in mild to moderate hypertension.
This study was undertaken to determine the correlations between left ventricular hypertrophy and left ventricular diastolic function in mild to moderate essential hypertension. M-mode echocardiography and rest equilibrium radionuclide angiography were performed in 53 hypertensive subjects. The following M-mode echocardiographic parameters were measured: interventricular septal thickness, posterior wall thickness, left ventricular mass index, left atrial diameter and relative wall thickness. The following radionuclide angiography parameters were measured: ejection fraction, peak filling rate, time to peak filling rate, first third filling fraction and atrial contribution to total filling. Weak correlations were shown between left ventricular diastolic function and the M-mode echocardiographic parameters. The peak filling rate was negatively correlated with the interventricular septal thickness (r = -0.345; P less than 0.05), with the sum of the interventricular septal thickness and the posterior wall thickness (r = -0.395; P less than 0.01), with the left atrial diameter (r = -0.345; P less than 0.05), and with the relative wall thickness (r = -0.297; P less than 0.05). The time to peak filling rate was positively correlated with the left ventricular mass index (r = + 0.310; P less than 0.05) and with the left atrial diameter (r = + 0.323; P less than 0.05). These findings suggest that diastolic abnormalities in hypertensive heart disease are only in part related to the degree of left ventricular hypertrophy.
