Predictors of Myocardial Infarction after Suprainguinal Bypass Using the Vascular Quality Initiative Cardiac Risk Index

Abstract

Several models have been developed to estimate the risk of postoperative myocardial infarction (POMI). The Vascular Quality Initiative (VQI) Cardiac Risk Index (CRI) was developed specifically for vascular procedures; while suprainguinal bypass carried the second highest odds of POMI, the all-procedure-based model performance declined when applied to the suprainguinal subset. We sought to refine the VQI CRI for application in this high-risk group undergoing open revascularization for aortoiliac occlusive disease.
