Six clinical predictors give a risk class for major adverse events.

High-risk surgery (intraperitoneal, intrathoracic, or suprainguinal vascular)

History of ischemic heart disease

History of congestive heart failure

History of cerebrovascular disease (stroke or TIA)

Diabetes requiring insulin therapy

Preoperative serum creatinine > 2.0 mg/dL
