Implications of Alternative Definitions of Peri-Procedural Myocardial Infarction After Coronary Revascularization

Varying definitions of procedural myocardial infarction (PMI) are in widespread use.This study sought to determine the rates and clinical relevance of PMI using different definitions in patients with left main coronary artery disease randomized to percutaneous coronary intervention (PCI) versus coronary artery bypass grafting (CABG) surgery in the EXCEL (Evaluation of XIENCE versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization) trial.The pre-specified protocol definition of PMI (PMIPMIThe rates of PMI after PCI and CABG vary greatly with different definitions. In the EXCEL trial, the pre-specified PMI
