| Popis: | Altered left ventricular (LV) diastolic filling has been shown in subjects with hypertension. Age is a major determinant of Doppler indexes of LV diastolic filling; therefore, a group of subjects of uniform age should preferably be chosen, if other determinants of diastolic LV filling are to be studied. A limited body of data is available regarding Doppler indexes of LV filling in hypertensive persons of a similar age. We therefore evaluated 26 hypertensive subjects (13 women and 13 men) 50 years old by Doppler echocardiography. The peak velocity of early diastolic filling (E wave), the peak velocity of atrial filling (A wave), the early-to-atrial peak velocity (E/A) ratio, and the deceleration time of early velocity were measured. The peak E wave velocity was 0.76 +/- 0.11 versus 0.62 +/- 0.13 m/s (P < 0.005), and the E/A ratio was 1.11 +/- 0.24 versus 0.93 +/- 0.23 (P < 0.05) in hypertensive women and men, respectively. The peak A wave velocity was increased and the E/A ratio was decreased in both hypertensive women and men compared with healthy 50-year-old subjects. In multivariate analyses, LV diameter, body mass index, and gender correlated with the E/A ratio in hypertensive persons. It is concluded that there is a significant difference in Doppler LV filling indexes between 50-year-old hypertensive women and men. LV diameter, gender, and body mass index are independent determinants of LV diastolic inflow in similarly aged hypertensive persons. |
