There is no agreement whether off-pump coronary artery bypass (OPCAB) can reduce mortality, rates of stroke, myocardial infarction, or revascularization when compared with conventional coronary artery bypass (CCAB). We performed a meta-analysis comparing off-pump coronary artery bypass with conventional coronary artery bypass in randomized controlled trials. ⋯ In conclusion, OPCAB did not significantly reduce 1-year mortality, stroke, myocardial infarction, and revascularization compared with CCAB.
