Abstract
We investigated the regression of left ventricular (LV) hypertrophy with long-term treatment of nifedipine in patients with systemic hypertension. Echocardiograms of the LV were obtained in nine patients before and at a mean of 50 months (13-105 months) after nifedipine monotherapy (30-60 mg/day). Nifedipine significantly reduced both systolic and diastolic blood pressures (BP) by a mean of -46 mmHg and -21 mmHg, respectively. With systemic BP reduction, LV mass was significantly reduced by a mean of -15%, associated with a decrease in LV posterior wall thickness and end-diastolic dimension. There was no significant change in LV fractional shortening. We conclude that nifedipine may cause regression of LV hypertrophy in systemic hypertension, and that reversal of the increase in LV mass could be maintained during long-term nifedipine treatment.
