['Recent studies and meta-analysis have shown that complete revascularization (CR) compared with infarct-related artery revascularization (IRA) during percutaneous coronary intervention for ST-segment elevation myocardial infarction (STEMI) is associated with decreased mortality. However, it is unclear if CR versus IRA in STEMI during indexed hospitalization is associated with risk of contrast-induced acute kidney injury (CI-AKI).', 'A database search was conducted for all randomized controlled trials that enrolled STEMI patients and compared CR versus IRA and reported CI-AKI. Comprehensive Meta-Analysis Version 2.0 (Wiley, Chichester) was used to determine summary effect size with a fixed-effect model and expressed as a risk ratio with 95\xa0% confidence intervals.', 'A total of four trials were identified and had a mean follow-up of 24.5\xa0±\xa09.9\xa0months, a total sample size of 1537, a mean age of 63.8\xa0±\xa01.2 versus 64.2\xa0±\xa02.1\xa0years, 31.2\xa0±\xa05.3 versus 30.1\xa0±\xa04.7\xa0% three-vessel disease, and 33.7\xa0±\xa04.1 versus 37.2\xa0±\xa04.5\xa0% anterior STEMI in the CR versus IRA groups, respectively. A total of 276.7\xa0±\xa025.2 versus 186.7\xa0±\xa015.3\xa0mL contrast was used in the CR versus IRA respectively (p\xa0=\xa00.006). There were no statistical significant differences between the two groups in the reported incidence of CI-AKI (1.3\xa0% CR vs. 1.9\xa0% IRA; p\xa0=\xa00.4), major bleeding (1.7\xa0% CR vs. 2.5\xa0% IRA; p\xa0=\xa00.4) and stroke (1.1\xa0% CR vs. 0.4\xa0% IRA; p\xa0=\xa00.24). However, there was a significantly increased incidence of cardiovascular death (2.0\xa0% CR vs. 4.7\xa0% IRA; p\xa0=\xa00.01) and ischemia-driven revascularization (6.2\xa0% CR vs. 18.3\xa0% IRA; p\xa0<\xa00.01).'] Does multivessel Revascularization Increase Contrast-Induced Acute Kidney Injury Incidence in Acute Myocardial Infarction : A Meta-Analysis?
