摘要
The benefits of coronary-artery bypass grafting （CABG） without cardiopulmonary bypass in the elderly are still undetermined. METHODS We randomly assigned patients 75 years of age or older who were scheduled for elective first-time CABG to undergo the procedure either without cardiopulmonary bypass （off-pump CABG） or with it （on-pump CABG）. The primary end point was a composite of death, stroke, myocardial infarction, repeat revascularization, or new renal-replacement therapy at 30 days and at 12 months after surgery.
