Does cigarette smoking impair endothelial function and coronary blood flow in patients with angiographically normal coronary arteries?
Cigarette smoking is associated with impaired coronary blood flow and endothelial function, likely mediated by oxidative stress, even in patients with angiographically normal coronary arteries.
