Troponin Cardiac Marker. Cardiac markers are biomarkers measured to evaluate heart function. Troponin or the troponin complex is a complex of three regulatory proteins that are integral to muscle contraction in skeletal muscle and cardiac muscle but not smooth muscle. Ck mb is not as specific as troponin and there are false positive reports of non ischemic cardiac injuries like pericarditis and myocarditis. When the heart is damaged it releases troponin into the bloodstream.
Troponin levels may not be detectable for six hours after the onset of myocardial cell injury. Serum levels increase within 3 12 hours from the onset of chest pain peak at 24 48 hours and return to baseline over 5 14 days. Indeed cardiac troponin is central to the definition of acute myocardial infarction mi in the consensus guidelines from the european society of cardiology esc and the american college of. The most sensitive early marker for myocardial infarction is myoglobin. Measurements of cardiac specific troponins i and t are extensively used as diagnostic and prognostic indicators in the management of myocardial infarction and acute coronary syndrome. Troponin t 0 to 0 1 µg l.
