To assess left ventricular (LV) diastolic function in patients with hypertension, a Doppler echocardiographic study of transmitral blood flow (TBF) was performed in 46 hypertensive patients (H), 18 without (H1) and 28 with (H2) left ventricular hypertrophy and in 25 age-matched normal subjects (N). All patients showed normal systolic function. The following indices of Doppler TBF were measured: peak flow velocity during early filling (Evel), atrial systole (Avel) and their ratio (E/Avel); area under early filling phase (Earea), area under atrial systole (Aarea), expressed as a percentage of total diastolic area and their ratio (E/Aarea); deceleration half-time (DHT) of early filling phase. When compared with N, H1 and H2 showed significant reductions in early filling indices and an increase in atrial contribution parameters. (Evel = 0.62 +/- 0.1(N), 0.52 +/- 0.1(H1) P less than 0.01, 0.44 +/- 0.1(H2) P less than 0.001; Earea = 56 +/- 5(N), 48 +/- 5(H1) P less than 0.001, 43 +/- 6(H2) P less than 0.001; Avel = 0.49 +/- 0.1(N), 0.59 +/- 0.1(H1) P less than 0.01, 0.69 +/- 0.14(H2) P less than 0.001; Aarea = 26 +/- 5(N), 41 +/- 4(H1) P less than 0.001, 47 +/- 7(H2) P less than 0.001). Also DHT was significantly prolonged, compared with N (80 +/- 12 msec), in H1 (90 +/- 12 msec, P less than 0.01) and H2 (105 +/- 20 msec, P less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)
