Cardiac troponins are the most sensitive and specific markers of myocardial injury. Cardiac troponin elevation are common in many diseases and do not necessarily indicate the presence of a thrombotic acute coronary syndrome. In clinical practice, interpretation of dynamic changes of troponin may be challenging. Troponin evaluation should be performed only if clinically indicated and must be interpreted in the context of clinical presentation, ECG changes, troponin level and kinetic. In the absence of thrombotic acute coronary syndrom, troponin retains a prognostic value. Its practical interest as a risk criteria is limited to a few situations like pulmonary embolism, pericarditis an myocarditis.
