Abstract

Two experiments were conducted to understand the influence of estrogen exposure on cardiovascular responses to acute stress measured by impedance cardiography. Study 1 compared stress responses of 29 postmenopausal women who used postmenopausal hormone replacement therapy (HRT) and 29 who did not use HRT. Women who did not use HRT had higher systolic blood pressure and pulse pressure responses to the tasks relative to HRT users. Study 2 compared stress responses of 38 healthy postmenopausal women not initially on HRT who were randomly assigned to transdermal estradiol or placebo treatment for 6–8 weeks. HRT assignment did not influence substantially women's cardiovascular responses to stress. Characteristics correlated with HRT use, not HRT itself, or differences in type, duration, and dosage may account for the discrepancy in results.
