Cardiac troponin elevation after coronary artery bypass graft: improving risk stratification

摘要

We read with great interest the article by Omran et al.1 as for the first time they investigated the additional role of high-sensitive cardiac troponin I (hs-cTnI) cut-off values after the first 48 h following elective coronary artery bypass graft (CABG) surgery in the decision-making process to repeat revascularization. We fully agree that in this setting, a comprehensive diagnostic evaluation including hs-cTnI values, clinical data, electrocardiogram (ECG) and echocardiographic findings is essential to guide patients’ management. Nevertheless, we believe that some critical issues undermine their conclusions.
