Defining Peri-Operative Myocardial Injury during Cardiac Surgery Using High-Sensitivity Troponin T.

Both baseline and post-operative hs-TnT elevations are independently associated with 1-year all-cause mortality in patients undergoing cardiac surgery. The optimal threshold to define a prognostically significant PMI in our study was ≥50 × URL elevation in hs-TnT at 24 h.
