Clinical Trial Summary

Retrospective observational study on the effects of altering components of RCRI to improve the predictive capacity.

Clinical Trial Description

The current Lee's Revised cardiac risk index (RCRI) was created in 1999. Validation studies have found RCRI to be only moderately discriminant. The "Diabetes Mellitus on insulin" component of the score does not accurately reflect the severity of the disease. A previously studied HbA1C:Hemoglobin ratio shows an improved association with outcomes than individual components alone and could be potentially used as a new marker for severity of the disease. A retrospective cohort study was performed in consecutive diabetic patients undergoing non-cardiac surgery. Ethics approval was obtained. The objective of the study is to compare the predictive value of RCRI and substitution of the "DM on insulin" component with HH ratio for 30- and 90-day mortality, and postoperative acute myocardial injury(AMI) and acute kidney injury(AKI). ;
