Acute coronary syndromes (ACS) frequently result from the rupture or erosion of a vulnerable coronary plaque, with associated intracoronary thrombosis. ACS also may occur in patients with angiographically normal coronary arteries. Some of these patients, however, still have angiographically silent underlying coronary artery disease. In this setting, subtle atherosclerotic changes ...
