Current guidelines recommend against revascularization of the noninfarct artery during the index percutaneous coronary intervention (PCI) in hemodynamically stable patients with ST-segment elevation myocardial infarction (STEMI). This was based largely on observational studies with few data coming from randomized controlled trials (RCTs). Recently, several small-to-moderate sized RCTs have provided data, suggesting that a multivessel revascularization approach may be appropriate. We performed a meta-analysis of RCTs comparing multivessel percutaneous coronary intervention (MV PCI) versus culprit vessel–only revascularization (COR) during primary PCI in patients with STEMI and multivessel coronary disease (MVCD). We searched Medline, PubMed, and Scopus databases for RCTs comparing MV PCI versus COR in patients with STEMI and MVCD. The incidence of all-cause death, cardiac death …
