Revised Cardiac Risk Index (Lee)

Pre-operative cardiac risk assessment. Recommended by ACC/AHA guidelines for non-cardiac surgery.

High-risk surgery — intraperitoneal, intrathoracic, or suprainguinal vascular

Ischaemic heart disease — MI, positive stress test, nitrate use, Q waves on ECG

Congestive heart failure

Cerebrovascular disease — prior stroke or TIA

Insulin-dependent diabetes mellitus

Pre-operative creatinine > 177 µmol/L (> 2.0 mg/dL)

RCRI/ 6

Very low cardiac risk

MACE risk: 0.4%
