Interventional Strategies for ST-Segment Elevation Myocardial Infarction and Multivessel Coronary Artery Disease.

Many patients with ST-segment elevation myocardial infarction (STEMI) have multivessel coronary artery disease (CAD) (1,2), yet interventional cardiologists can almost always identify a single lesion responsible for the infarction. After successful percutaneous coronary intervention of the infarct-related lesion (culprit PCI), there are 2 competing strategies available for STEMI patients with multivessel CAD. Additional lesions in noninfarct vessels can be treated immediately at the same sitting (multivessel PCI) or they can undergo delayed evaluation and treatment during another session (staged PCI).
