Abstract:
Transmitral left ventricular diastolic inflow velocities determined by pulsed Doppler in 47 normotensives, 80 hypertensives and 44 age-matched hypertensives were measured to evaluate the effects of age and left ventricular hypertrophy on left ventricular diastolic fuction in normotensives and hypertensives. The results were as follows: 1) The peak E velocity in normotensives(77.82+/-13.53cm/sec) was significantly different from those of hyeprtensives(58.13+/-11.80cm, p<0.01) and age-matched hypertensives(59.31+/-10.94cm/sec, p<0.01). The peak E/A in normotensives(1.31+/-0.45) was significantly different from those of hypertensives(0.83+/-0.21,p<0.01) and age-matched hypertensives(0.83+/-0.20, p<0.01). 2)In normotensives, simple linear regression analysis revealed strong inverse correlations of peak E with age(r=-0.758, p<0.01), peak E/A with age(r=-0.748, p<0.01), but no significant correlation of peak E and peak E/A with LVMI(p>0.05). Stepwise regression analysis revealed that age was the most important correlate of peak E and peak E/A in normotensives(peak E: R
