Revised Cardiac Risk Index (RCRI) Overview

The Revised Cardiac Risk Index (RCRI), also known as the Lee Score, is a simplified and highly effective clinical tool used to estimate the risk of major adverse cardiac events (MACE) following non-cardiac surgery.

The Six Predictors

The RCRI uses six key independent variables to assess risk:

  1. High-risk surgery (intraperitoneal, intrathoracic, or suprainguinal vascular).
  2. History of ischemic heart disease.
  3. History of congestive heart failure.
  4. History of cerebrovascular disease.
  5. Diabetes mellitus requiring insulin.
  6. Preoperative serum creatinine > 2.0 mg/dL.

Score = Sum of active risk factors (0-6)

Where:
0 Factors=
0.4% risk of MACE
1 Factor=
0.9% risk of MACE
2 Factors=
6.6% risk of MACE
≥3 Factors=
>11% risk of MACE

Frequently Asked Questions

This includes vascular surgery, as well as intrathoracic or intraperitoneal procedures which carry a higher physiological stress load.

RCRI is simpler and easier to calculate at the bedside, whereas NSQIP is a more complex, data-heavy model that requires a computer but offers more granular risk estimates.
