hsTnT role in diagnosing perioperative MI after cardiac surgery remains unassessed; leaves open its utility versus TnT or CK-MB.
Perioperative myocardial infarction (PMI) in the setting of cardiac surgery represent a considerable risk to patients with significant mortality and morbidity. The role of highly sensitive cardiac troponin T (hsTnT) has not been evaluated in the setting of cardiac surgery, instead Cardiac Troponin T (TnT) and Creatine Kinase MB (CK-MB) are commonly used for the diagnosis of PMI [ 1 ].

Omar et al. (2015) conducted an observational in Cardiac surgery (n=413). High sensitive troponin T (hsTnT) vs. CK-MB was evaluated on Diagnosis of perioperative myocardial infarction (PMI) (90% sensitivity and 90% specificity). A high-sensitive troponin T cut-off level of 3466 ng/L demonstrated 90% sensitivity and 90% specificity for diagnosing perioperative myocardial infarction after cardiac surgery.
