Review Meta Analysis Comparative Study
Meta-Analysis of Randomized Controlled Trials Comparing Multivessel Versus Culprit-Only Revascularization for Patients With ST-Segment Elevation Myocardial Infarction and Multivessel Disease Undergoing Primary Percutaneous Coronary Intervention.
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. ⋯ During long-term follow-up (range 1 to 2.5 years), combined data indicated a significant reduction in all-cause mortality (relative risk [RR] 0.57, 95% confidence interval [CI] 0.36 to 0.92, p = 0.02) and in cardiac death (RR 0.38, 95% CI 0.20 to 0.73, p = 0.004) with MV PCI. In addition, there was a significantly lower risk of recurrent myocardial infarction (RR 0.41, 95% CI 0.23 to 0.75; p = 0.004) and future revascularization (RR 0.37, 95% CI 0.27 to 0.52; p <0.00001). In conclusion, from the RCT data, MV PCI appears to improve outcomes in patients with STEMI and MVCD.
