Results Overview

Short-term end point was a composite of death or major complications (reoperation, new mechanical support, cardiac arrest, coma, stroke, or renal failure requiring dialysis) occuring within 30 days after surgery or before discharge, whichever was later.

Participant Flow

From February 2002 to May 2007, a total of 9663 patients who were scheduled for urgent or elective Coronary Artery Bypass Graft (CABG) were screened for enrollment. Of these, 7460 patients were excluded, mostly because of diffusely diseased or small coronary arteries. Overall,1099 patients were randomized to on-pump and 1104 randomized to off-pump
