a. Operative mortality in patients > 70 years is more than double that of younger patients
b. If the patient is a woman, the risk is higher than it would be for a man
Operative mortality for patients > 70 years was 8% in the CASS study as compared to 3% in younger patients. For reasons not entirely clear, the risk of CABG is higher in women than in men. Reoperative procedures carry a higher operative mortality due to technical difficulties, more advanced disease, and less complete revascularization. Congestive heart failure is a major determinant of poor surgical outcome, but the results are better when there is viable myocardium (hibernating) than when there is irreversible ischemic cardiomyopathy
