Identifying the Infarct-Related Artery in Patients With Non–ST-Segment–Elevation Myocardial Infarction

Abstract

Identification of the IRA by coronary angiography can be challenging in patients with non-ST-segment-elevation MI. In nearly half, DE-CMR may lead to a new IRA diagnosis or elucidate a nonischemic pathogenesis. Revascularization solely of coronary arteries that are believed to be nonculprit arteries by DE-CMR is not uncommon.
