Oestradiol-17β causes relaxation of isolated coronary arteries and increases blood flow in several vascular beds in human beings and animals. Oestrogen replacement therapy is associated with a lower incidence of cardiovascular disease, but the acute effects of Oestradiol-17β on myocardial ischaemia are unknown. We have studied the acute effect of sublingual oestradiol-17β on exercise-induced myocardial ischaemia in eleven women (mean age 58 [SD 8] years) with coronary artery disease. The women did two treadmill exercise tests on separate days; 40 min before the test they took sublingual oestradiol-17β (1 mg) or placebo, in random order. Plasma Oestradiol-17β concentrations were confirmed to be higher after sublingual oestradiol-17β than after placebo (2531 [1192] vs 155 [168] pmol/L, p
