Detection of myocardial damage - Are the troponins the ultimate solution?

Abstract

Biochemical markers of myocardial damage are together with the clinical history, the physical examination and the 12-lead ECG key elements in the clinical evaluation of patients presenting with symptoms suggestive of an acute coronary syndrome (ACS). In this situation the detection of myocardial damage, even very minor, is of importance, not only for diagnosis, but also for risk assessment and selection of treatment. The new markers of myocardial damage, troponin T and I, have been shown to offer some advantages over the conventional markers in ACS and there is also an increasing interest for troponins in other clinical situations, e.g. after surgery and percutaneous coronary intervention. This paper will discuss the role of troponins in these different clinical situations.
