Improvement of endothelial function has been implicated in the cardioprotective effects of estrogens in women. In isolated human coronary arteries, we investigated whether 17beta-estradiol affects endothelium-dependent responses to bradykinin, an endothelium-derived vasodilator locally produced by endothelial cells. Concentration-response curves to bradykinin (0.03-300 nM) or nitroglycerine (0.01-1 microM) were obtained before and after 30 min of incubation with 17beta-estradiol (3 microM) or solvent control (ethanol 0.2% vol/vol). Incubation with 17beta-estradiol enhanced relaxations to bradykinin (from 43 +/- 6 to 83 +/- 3%, P < 0.0001) but not those to nitroglycerine (n.s.). Improvement of bradykinin-mediated endothelium-dependent relaxation may represent a novel mechanism contributing to the cardioprotective effects of estrogen in women.
