About Revised Cardiac Risk Index (RCRI)

The Revised Cardiac Risk Index (RCRI) is an essential clinical tool designed to estimate a patient's risk of major cardiac events—such as myocardial infarction, cardiac arrest, or death—following non-cardiac surgery. Developed by Lee et al., this evidence-based index helps clinicians, anesthesiologists, and surgeons quickly stratify pre-operative risk. It calculates a score based on six independent predictors: high-risk type of surgery, history of ischemic heart disease, history of congestive heart failure, history of cerebrovascular disease, pre-operative insulin therapy for diabetes, and pre-operative serum creatinine greater than 2.0 mg/dL. The RCRI provides a rapid, objective assessment, aiding in personalized perioperative management, informing discussions with patients, and optimizing surgical planning to enhance patient safety and outcomes.
