Several risk factors for post-operative cardiac complications after major noncardiac surgery have been identified. Goldman et al. in 1977 published a prospective study of 1001 patients over the age of 40 and identified “nine independent significant correlates of life-threatening and fatal cardiac complications”. The Goldman cardiac risk index emerged this data. Subsequently, several modified risk indices and criteria have been published. Modern day models used to predict post-operative cardiac events include the MICA (myocardial infarction cardiac arrest) calculator, the RCRI (revised cardiac risk index), and the newer ACS-NSQIP (American College of Surgeons National Surgical Quality Improvement Program) surgical risk calculator. The criteria for MICA and RCRI are listed below. The NISQIP calculator is an online web application that utilizes 22 characteristics and is more comprehensive than the other models.
