To reduce cardiovascular complications, antihypertensive therapy should not only normalize blood pressure but also induce a regression of structural abnormalities, which are the expression of end-organ damage. We investigated the effects of transdermal 17 beta-estradiol, combined with standard antihypertensive therapy, on the modification of left ventricular anatomy and systolic performance in hypertensive postmenopausal women. In a randomized, double-blind, placebo-controlled study, we enrolled 169 postmenopausal women with mild or moderate hypertension. Eighty-six patients (group 1) received transdermal 17 beta-estradiol (50 mu g/d) and norethisterone acetate (2.5 mg/d, orally), and 83 patients (group 2) received placebo. At baseline, all women underwent M-mode and 2-D echocardiogram, which was repeated after 6, 12, and 18 months of follow-up. After 18 months of treatment, we observed a significant decrease in left ventricular diastolic septal and posterior wall thickness and mass in both groups. Furthermore, after 18 months, left ventricular mass was significantly less than in the estrogen-treated group. No significant modifications were observed in left ventricular systolic and diastolic dimensions or in systolic performance, as expressed by left ventricular fractional shortening. In conclusion, transdermal 17 beta-estradiol, which is associated with antihypertensive therapy, may contribute in the reduction of left ventricular mass in hypertensive postmenopausal women.
