Coronary artery bypass grafting (CABG) has been performed for elderly patients with increasing frequency. Several studies have shown that the rate of complications and mortality in elderly patients are higher than in younger ones. This report presents results of CABG in patients over 75 years old. From January 1989 to February 1997, 604 patients underwent CABG, of whom 20 patients (3.3%) were 80-86 years old (group A) and 57 patients (9.4%) were 75-79 years old (group B). We compared these two groups with 100 younger patients (group C). Preoperative use of intraaortic balloon pumping and the emergency operation were more frequent in patients of group A (emergency 45%, IABP 20%). And the proportion of the no blood transfusion procedures was lower in elderly patients (group A 20%, group B 18%, group C 82%). The number of grafts per patient (group A 2.45 +/- 0.62, group B 2.2 +/- 0.6, group C 3.2 +/- 0.6) and the number of arterial grafts (group A 1.25 +/- 0.62, group B 1.25 +/- 0.66, group C 2.1 +/- 0.53) were different between the groups. But CABG in elderly patients was performed with low hospital mortality (group A 0%, group B 0.18%) and significant symptomatic benefit. We conclude that CABG can be performed in elderly patients with acceptable mortality and acceptable quality of life, so patients should not denied operation because of an advanced age.
