What is MI related to CABG?
Myocardial infarction (MI) related to CABG is arbitrarily defined by elevation of cardiac biomarker values greater than the 99th percentile upper reference limit (URL) in patients with normal baseline cardiac troponin (cTn) values less than the 99th percentile URL. In addition, either (i) new pathological Q waves or new left bundle-branch block (LBBB), or (ii) angiographically documented new graft or new native coronary artery occlusion, or (iii) imaging evidence of new loss of viable myocardium or new regional wall motion abnormality must be present.
