The effects of 6 months treatment with nifedipine 20 mg SR (N) or verapamil 240 mg SR (V) on rest and exercise BP and left ventricular mass (LVM) and function were evaluated in 31 essential hypertensive patients (mean age: 54, 19 males, 12 females), never treated with calcium antagonist. After a 15 days placebo run in, BP was measured at rest and during a maximal bicycle exercise test (stages: 30 watts, 3 min). 2D guided M mode echocardiography and pulsed Doppler allowed assessment of left ventricular mass (Devereux's formula) and function (fractional shortening FS, peak early (E) and late (A) velocities of LV filling). Patients were randomised to N (n = 18) or V (n = 13) and reassessed 6 months later. All echo-Doppler recordings were read blindly by 2 observers. RESULTS rest BP was similarly reduced in both groups (V: 148 +/- 12/88 +/- 5 vs 162 +/- 10/101 +/- 7; N: 148 +/- 15/90 +/- 7 vs 170 +/- 14/101 +/- 8), as well as exercise maximal BP (V: 224 +/- 32/93 +/- 11 vs 243 +/- 21/104 +/- 11; N: 206 +/- 27/90 +/- 10 vs 231 +/- 17/97 +/- 8). The duration of exercise was significantly increased with V (15 +/- 5 min vs 12 +/- 4, p < 0.05) and insignificantly decreased with N (11 +/- 2 vs 12 +/- 3). Left ventricular mass was higher in V group at entry and was significantly more reduced with V (250 g +/- 74 vs 302 g +/- 92, p < 0.01) than with N (225 g +/- 54 vs 234 g +/- 69).(ABSTRACT TRUNCATED AT 250 WORDS)
