Coronary artery bypass in patients 80 years and older: comparison with a younger age group.
Octogenarians are at increased risk for perioperative morbidity and mortality following coronary artery bypass grafting (CABG). We compared the perioperative outcome after CABG from March 1997 to June 2003, between patients 80 years and older (n=15), and those aged 70 to 79 years (n=64). In comparison with younger patients, more octogenarians had congestive heart failure (40% vs. 9% in patients aged 70 to 79 years, p=0.003) and underwent off-pump CABG more frequently (80% vs. 42%, p=0.008). There were no significant differences in the incidence of emergent surgery (27% vs. 28%) and number of bypass grafts (2.3+/-0.7 vs. 2.5+/-0.9) between the two groups. Octogenarians had less complete revascularization compared to the younger group (67% vs. 81%, not significant). There was no mediastinitis, and no stroke in either groups. Octogenarians had more minor wound complications (20% vs. 3%, p=0.01). There were no operative deaths in octogenarians, while the mortality rate of the younger group was high (6%). Surgical myocardial revascularization in octogenarians can be performed with acceptable mortality and morbidity using off-pump CABG.
