Background: Most data suggesting that noncardiac surgery early after coronary artery bypass surgery carries low risk are derived from post hoc analyses of randomized controlled trials, with only limited data derived from contemporary, nonselected, and nontrial patients. Methods: We retrospectively reviewed the medical records of patients who underwent coronary artery bypass surgery at our institution between January 1999 and October 2006 to determine whether they subsequently had major noncardiac surgery and what the outcomes of the noncardiac surgery were. Results: During the study period, 1065 patients underwent coronary artery bypass surgery, and 272 (26%) subsequently underwent 467 major noncardiac surgeries. The mean interval from coronary artery bypass to noncardiac surgery was 1.9 ± 1.9 years (range, 0Y7. 8 years). A major complication occurred in 3 surgeries (0.6% [95% confidence interval, 0.1%Y1.9%]). Two patients died (both from respiratory arrest during the postoperative period: 1 patient had a tongue cancer excision, and the other patient had polycythemia vera), and the third patient had a perioperative arrhythmia. Conclusions: Noncardiac surgery is often required early after coronary artery bypass surgery and carries very low risk for cardiac complications, suggesting that preoperative cardiac evaluation may not be required in most such patients.
