Revised Cardiac Risk Index (RCRI / Lee)

Predicts perioperative risk of major cardiac complications in non-cardiac surgery.

One point per criterion. ≥2 points often triggers further cardiac workup.

High-risk surgery (intraperitoneal, intrathoracic, suprainguinal vascular)Ischemic heart disease (MI, +stress test, current angina, nitrate use, Q-waves)History of congestive heart failureHistory of cerebrovascular disease (TIA/stroke)Diabetes mellitus on insulinCreatinine > 2.0 mg/dL
