Predicting Myocardial Injury and Other Cardiac Complications After Elective Noncardiac Surgery with the Revised Cardiac Risk Index: The VISION Study

BACKGROUND: The Revised Cardiac Risk Index (RCRI) is widely used to estimate risk of cardiac complications after noncardiac surgery; its estimates do not capture myocardial injury after noncardiac surgery (MINS). We evaluated the incidence of cardiac complications including MINS across RCRI risk classes and the RCRI's ability to discriminate, before surgery, between patients who will experience these complications and those who will not.
