Type 5: MI related to CABG MI associated with CABG is arbitrarily defined by elevation of cardiac biomarker values >10 99th percentile URL in patients with normal baseline cTn values (<99th percentile URL). In addition, either (i) new pathological Q waves or new 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. CABG indicates coronary artery bypass graft; CAD, coronary artery disease; cTn, cardiac troponin; LBBB, left bundle-branch block; LVH, left ventricular hypertrophy; MI, myocardial infarction; MVO2 , myocardial oxygen consumption; PCI, percutaneous coronary intervention; and URL, upper reference limit.
