1 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. 2  Troponin levels may not be detectable for six hours after the onset of myocardial cell injury. 3  The most sensitive early marker for myocardial infarction is myoglobin.
Assays for cTn, namely cTnI and cardiac troponin T (cTnT), are the preferred diagnostic tests for ACS, in particular nonâST-segmentâelevation myocardial infarction, because of the tissue-specific expression of cTnI and cTnT in the myocardium. The results of cTn testing often guide the decision for coronary intervention.
