A total of 67,568 patients were identified who were ≥70 years old and underwent CABG. Compared to the Septuagenarians, the Octogenarians were more likely to develop cardiac complications (OR [odds ratio] =1.20, 95% CI [confidence interval] 1.12-1.23. They were also more likely to develop renal complications (P <0001), and respiratory complications (P <0001). The Octogenarians were also more likely to bleed postoperatively (P <0.0001) and have a higher mortality (P <0001). Furthermore, the female Octogenarians had a higher mortality (OR 1.25 95% CI 1.07–1.46) compared to males in the same age group.
