AbstractIn-hospital mortality after cardiac surgery ranges from 2% to 8%. Many patients suffer from major adverse cardiovascular events, e.g. myocardial infarction, which in the long term can result in severe limitations in routine activities. Troponin plays the central role in identifying myocardial infarction; however, interpretation after cardiac surgery is difficult due to ischemia reperfusion injury and direct surgical trauma. Thus, the distinction between procedure-related myocardial injury and additional myocardial injury due to a new event is difficult. The fourth universal definition of type 5 myocardial infarction uses the 10 × upper limit of normal (ULN) as cut-off and notably > 90% of patients after on-pump procedures exceed this cut-off. Clinical consequences are mostly unclear. The dynamics of copeptin and heart-type fatty acid binding protein (H-FABP) concentrations start very early, i.e. several hours before troponin. The characteristics of copeptin and H‑FABP might help to overcome the limitations of troponin. This short narrative review gives a concise overview on this topic. Moreover, a brief view of future perspectives in this field is given.© 2021. Springer Medizin Verlag GmbH, ein Teil von Springer Nature.
