Perioperative Myocardial Injury in Patients Undergoing Coronary Artery Bypass Grafting: A Prospective Clinical Study
Sponsor: Second Hospital of Jilin University
Summary
Perioperative myocardial injury (PMI) following coronary artery bypass grafting (CABG) is associated with postoperative morbidity, mortality, and long-term outcomes. High-sensitivity troponin assays and cardiac MRI offer reliable diagnostic tools for PMI, but evidence regarding optimal diagnostic thresholds and perioperative imaging strategy is limited. This prospective clinical study aims to determine the incidence of perioperative myocardial injury using multimodal assessments including high-sensitivity troponin, electrocardiogram, echocardiography, cardiac MRI, and perioperative cardiovascular events.

Interventions
High-Sensitivity Troponin
High-sensitivity troponin levels are measured preoperatively, predischarge, and at 6-month follow-up to assess perioperative myocardial injury.
Cardiac MRI
A diagnostic assessment panel including high-sensitivity troponin testing, electrocardiography, echocardiography, and cardiac magnetic resonance imaging performed during the perioperative period.
