Troponin

Common card · No. 204715

Troponin, or the troponin complex, is a complex of three subunits of specialized regulatory proteins –troponin C, troponin I, and troponin T, that are components of the contraction mechanism in striated muscle. Measurements of cardiac-specific troponins I and T are extensively used as diagnostic and prognostic indicators in the management of myocarditis, myocardial infarction and acute coronary syndrome. Blood levels of cardiac troponin (cTn) may be used as a diagnostic marker for stroke or other myocardial injury that is ongoing, although the sensitivity of this measurement is low.
