  • PURPOSE OF REVIEW: Multivessel disease (MVD) is common in ST-segment elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PCI) and is associated with significant risk of future cardiovascular (CV) events including short and longer-term mortality. In this review, we examine the pathophysiologic construct contributing to adverse prognosis of MVD in STEMI, relevant available evidence that currently guides the management of the noninfarct-related artery (IRA) stenosis and define the remaining knowledge gaps for future studies. RECENT FINDINGS: Results of recent small sized randomized trials, when pooled, suggest improvement in CV outcomes including CV mortality and repeat revascularization with revascularization of the non-IRA stenosis compared with medical management alone. In addition, there does not appear to be an increase in bleeding, contrast-induced nephropathy or stroke, as suggested by earlier observational data. SUMMARY: These recent data have led to a Class IIb recommendation in the American College of Cardiology/American Heart Association guidelines stating that non-IRA revascularization may be considered in selected patients with STEMI and MVD who are hemodynamically stable, either at the time of primary PCI or as a planned staged procedure. The ongoing COMPLETE and CULPRIT-SHOCK studies will provide additional data to further inform the role of non-IRA revascularization and its timing in the management of these patients.
