Early Prognostic Value of High-Sensitivity Troponin T after Coronary Artery Bypass Grafting.

Background:  Periprocedural myocardial injury after coronary artery bypass grafting (CABG) may affect the patient's prognosis and may be due to a different set of factors beyond the atherosclerotic plaque instability. Considering the challenges in the diagnosis of myocardial injury after CABG, the aim of this study was to determine the association between postoperative early elevation of high-sensitivity troponin T (hsTnT) and all-cause 30-day mortality after CABG.

Methods:  We enrolled 600 consecutive patients who underwent CABG.
