چکیده
background: the incidence of coronary artery bypass grafting surgery (cabg) in elderly patients has been increasing. there are contradictory reports on the early outcome of elderly coronary artery patients as compared with their young counterparts. we designed this retrospective study to address this issue. methods: w e retrospectively analyzed the results of 1489 on–pump cabg cases performed at our hospital during a 4.5-year period. perioperative data such as demographic, medical, clinical, operative, and postoperative variables were collected and compared between patients 70 years old or younger (group a, n = 1164) and patients above 70 years of age (group b, n = 325). statistical analysis was performed using the t-test for the continuous and the x 2 tests for the categorical variables. significant variables according to the univariate analysis (x 2 and t-test) were further analyzed using multivariate logistic regression analysis. results: the variables of weight (p value < 0.001), preoperative p o2(p value = 0.005), ejection fraction > 30% (pvalue = 0.001), body surface area (p value = 0.003), and hypercholesterolemia (p value = 0.007) were higher in group a, whereas preoperative myocardial infarction (p value < 0.001), postoperative low cardiac output syndrome (p value = 0.019), emergent surgery (p value = 0.003), inotropic drug use (p value < 0.001), preoperative heparin use (p value < 0.001), re-exploration for bleeding (p value = 0.015), hospital stay (p value < 0.001), low ejection fraction (≤ 30%) (p value = 0.001), preoperative creatinine > 1.5 mg/dl (p value < 0.001), chronic obstructive pulmonary disease (p value < 0.001), intra-aortic balloon pump use (p value < 0.001), infection (p value < 0.001), pulmonary complications (p value < 0.001), atrial fibrillation (p value < 0.001), postoperative renal complications (p value < 0.001), and death (p value = 0.012) were more frequent in group b. conclusion: cabg in the elderly patients had certain surgical risks such as chronic obstructive pulmonary disease, preoperative myocardial infarction, emergent surgery, and death. also, postoperative complications such as pulmonary complications, inotropic drug use, intra-aortic balloon pump use, and infection were more frequent in the elderly than in the younger patients.
