The Revised Cardiac Risk Index (RCRI) is a clinical prediction rule for use during preoperative care for prediction major cardiac complications of noncardiac surgery.[1] The original index was published in 1977.[2]
The component of the Index are:
- high-risk surgery (intraperitoneal, intrathoracic, or vascular surgery above the inguinal ligaments). See prognosis by surgery type.
- history of ischemic heart disease
- history of congestive heart failure
- history of cerebrovascular disease
- preoperative treatment with insulin
- preoperative serum creatinine >2.0 mg/dL
| Number of risk factors | Mortality | |
|---|---|---|
| Major cardiac complications (Original study)[1] |
Cardiovascular death (Independent validation)[3] | |
| ≥ 3 | 11% | 3.6% |
| 2 | 7% | 1.7% |
| 1 | 0.9% | 0.7% |
| 0 | 0.4% | 0.3% |
The RCRI has been validated among patients although exploratory analyses suggested that adding age and surgical details would improve the model.[3] The RCRI has been validated among patients undergoing surgery for peripheral arterial disease.[4]
