Revised Cardiac Risk Index (Lee Criteria)

Rapid pre-op assessment using the Revised Cardiac Risk Index


The revised cardiac risk index was developed from stable patients aged 50 years or more undergoing elective major non-cardiac procedures in a tertiary-care teaching hospital. This index can identify patients at higher risk for complications such as myocardial infarction, pulmonary edema, ventricular fibrillation or primary cardiac arrest, and complete heart block. This index may be useful for identification of candidates for further risk stratification with noninvasive technologies or other management strategies (moderate risk or above), as well as low-risk patients in whom additional evaluation is unlikely to be helpful. This risk index should be used in the context of the ACC/AHA 2007 Guidelines on Perioperative Cardiovascular Evaluation and Care for Noncardiac Surgery.
