Revised Cardiac Risk Index (RCRI)

The RCRI assesses the risk of major cardiac complications (e.g., myocardial infarction, cardiac arrest, pulmonary edema) based on six risk factors:

1. High-risk surgery (e.g., intraperitoneal, intrathoracic, or suprainguinal vascular surgery)

2. History of ischemic heart disease

3. History of congestive heart failure

4. History of cerebrovascular disease

5. Diabetes mellitus requiring insulin therapy

6. Preoperative serum creatinine >2.0 mg/dL

Each risk factor is assigned 1 point. The total score correlates with the risk of major cardiac complications.
