Abstract
To study smooth muscle function in atherosclerosis, we calculated dose-resp onse curves in patients with coronary artery disease and in controls by mea suring changes in brachial artery diameter after incremental sublingual dos es of nitroglycerin. The doses required to produce a 50% maximal dilator re sponse were significantly higher in patients with coronary artery disease t han in controls (p < 0.002), suggesting smooth muscle dysfunction in athero sclerosis.
