Independent Predictors of Postoperative Cardiac Complications

1. Intrathoracic, intraperitoneal, or infrainguinal vascular surgery
2. History of ischemic heart disease
3. History of congestive heart failure
4. Insulin treatment for diabetes mellitus
5. Serum creatinine level > 2 mg/dL [> 176.8 mcmol/L]
6. History of cerebrovascular disease
