Abstract: Abstract Objective: To investigate the peri-operative treatments of coronary artery bypass grafting in octogenarians. Methods: From January 2008 to March 2011, 37 patients(30 male,7 female) 80 years of age or older(80-91years,mean 83.11±2.90 years) underwent coronary artery bypass grafting. 31 patients underwent off pump coronary artery bypass grafting (83.8%) and 1 patients underwent conventional on pump coronary artery bypass grafting (2.7%) and 3 patients underwent simultaneous mitral valve replacement and coronary artery bypass grafting (8.1%) and 2 patients underwent simultaneous aortic valve replacement and coronary artery bypass grafting (5.4%). Results: One patients died post-operatively. The mortality was 2.7%. Major postoperative complications included atrail fibrillation in 18 cases, respiratory dysfunction in 8 cases( 1 patients underwent trachyotomy), low cardiac output in 6 cases,acute kidney injury in 2 cases(2 patients underwent continuous renal replacement treatment) and stroke in one case. Hemorrhage or tamponade requiring reoperation in 1 cases. Intra-aortic balloon pump was used in 7 patients (18.9%). The average ICU stay was 3.35±1.99 days. Mean postoperative in-hospital stay was 13.03±4.39 days. Thirty-seven patients were followed up from 3-39 months. One patient died during the follow-up period. Conclusions: Coronary artery bypass grafting in octogenarians is safe. Intensive perioperative treatment should be stressed in octogenarians to reduce the morbidity and mortality.
