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.
