Abstract

Objective: Diagnosis of perioperative myocardial infarction (P-MI) after coronary artery bypass graft (CABG) surgery traditionally relied on a combination of electrocardiographic and enzyme assay changes. Patients with Q-wave P-MIs who survive to hospital discharge have a poorer long-term prognosis. Troponin assays are more sensitive and specific for detecting minor P-MI, with an increased incidence of P-MI being reported. This study investigated if P-MI after CABG surgery, as defined by troponin-I isozyme (cTn-I), correlated with long-term outcome. Design: A prospective, observational study. Setting: A single-institution, cardiothoracic specialty hospital. Participants: Seventy patients undergoing elective CABG surgery. Interventions: Patients (n = 70) were stratified into low-risk and high-risk groups according to the absence (cTn-I
