Infarct-related artery only revascularization versus multi-vessel revascularization for patients with Killip I-IV acute myocardial infarction and multivessel disease.

Multivessel revascularization significantly reduced the incidence of cardiovascular death for patients presenting with AMI and multivessel CAD, particularly for Killip I-II patients. There were no significant differences in the primary outcome across the groups of patients with Killip III-IV.
