%X objective: to analyze the results of isolated on-pump coronary artery bypass graft surgery (cabg) in patients >70 years-old in comparison to patients <70 years-old. methods: patients undergoing isolated cabg were selected for the study. the patients were grouped in g1 (age > 70 years-old) and g2 (age <70 years-old). the endpoints were in-hospital mortality, acute myocardial infarction (ami), stroke, reexploration for bleeding, intra-aortic balloon for circulatory shock, respiratory complications, acute renal failure, mediastinitis, sepsis, atrial fibrillation, and complete atrioventricular block (cavb). results: 1,033 patients were included, 257 (24.8%) in g1 and 776 (75.2%) in g2. patients in g1 were more likely to have in-hospital mortality than g2 (8.9% vs. 3.6%, respectively; p=0.001), while the incidence of ami was similar (5.8% vs. 5.5%; p=0.87) than g2. more patients in g1 had re-exploration for bleeding (12.1% vs. 6.1%; p=0.003). g1 had more incidence of respiratory complications (21.4% vs. 9.1%; p<0.001), mediastinitis (5.1% vs. 1.9%; p=0.013), stroke (3.9% vs. 1.3%; p=0.016), acute renal failure (7.8% vs. 1.3%; p<0.001), sepsis (3.9% vs. 1.9%;p=0.003), atrial fibrillation (15.6% vs. 9.8%; p=0.016), and cavb (3.5% vs. 1.2%; p=0.023) than g2. there was no significant difference in the use of intra-aortic balloon. in the forward stepwise multivariate logistic regression analysis age > 70-year-old was an independent predictive factor for higher in-hospital mortality (p=0.004), reexploration for bleeding (p=0.002), sepsis (p=0.002), respiratory complications (p<0.001), mediastinitis (p=0.016), stroke (p=0.029), acute renal failure (p<0.001), atrial fibrillation (p=0.021) and cavb (p=0.031). conclusion: this study suggests that patients > 70 years-old were at increased risk of death and other complications in the cabg's postoperative period in comparison to younger patients.
