Abstract

Objective: Limited information is available on the effects of transdermal estradiol on diastole. The present study was a randomized double- blind placebo-controlled trial designed to investigate the short-term effects of transdermal estradiol on left ventricular diastolic function in postmenopausal women. Methods: The study included 45 women aged 50.8 ± 3.6 years (25 randomized to the study group and 20 to placebo), who underwent Doppler echocardiography and determination of the plasma estradiol level after 4 and 8 weeks of transdermal estradiol administration in a dose of 50 μg per 24 h. Results: There were no modifications in heart rate. Systolic blood pressure dropped in the study patients after 8 weeks (p < 0.03); diastolic blood pressure remained unchanged. Estradiol levels were 67 ± 36 pg/ml at 4 weeks and 70 ± 49 pg/ml at 8 weeks in the study group. Basal values of peak early and peak atrial velocities, acceleration time and rate, deceleration time and rate, early/atrial velocity ratio and pressure half- time were not significantly different between the estradiol and placebo groups. Doppler values remained unchanged after both 4 and 8 weeks in women receiving estradiol. Women with relatively high serum 17β-estradiol levels (> 100 pg/ml) at 4 or 8 weeks of treatment did not present more pronounced changes in the Doppler-derived parameters compared with patients with low hormone levels. Conclusion: The results showed a lack of short-term effects of transdermal estradiol on left ventricular diastolic function in postmenopausal women, irrespective of serum estradiol levels.
