%X objective: the objective of this study is to compare the immediate results of patients undergoing on-pump versus off-pump coronary artery bypass graft (cabg) surgery. methods: from january 2007 to january 2009, 177 patients underwent cabg, being 92 off-pump and 85 onpump. we evaluated the demographics, preoperative risk factors, preoperative functional class and risk assessment by the euroscore. the postoperative evolution was compared between groups. results: the mean number of grafts per patient was 2.48 ¡À 0.43 in off-pump group and 2.90 ¡À 0.59 in on-pump group. in the off-pump group, 97.8% of patients received an internal thoracic artery graft, while on-pump group the percentage was 94.1% (p = 0.03). the rate of complete revascularization was similar in both groups. in off-pump group, the circumflex artery was revascularized in 48.9% and 68.2% in the onpump group (p = 0.01). hospital mortality was 4.3% and 4.7%, respectively in the off-pump group in the on-pump group (p = 0.92). off-pump group had fewer complications in relation to perioperative myocardial infarction (p = 0.02) and use of intra-aortic balloon pump (p = 0.01). conclusion: the off-pump cabg is a safe procedure with hospital mortality similar to that observed in on-pump cabg, with lower rates of complications and less need for intra-aortic balloon.
