WebIn accordance with all the most recent international guidelines, the variation of circulating levels of cardiac troponins I and T, measured with high-sensitivity methods (hs-cTnI and hs-cTnT), should be used for the detection of acute myocardial WebAs a result of its high tissue‑specificity, cardiac troponin T (cTnT) is a cardiospecific, highly sensitive marker for myocardial damage. In cases of acute myocardial infarction (AMI), troponin T levels in serum rise about 3‑4 hours after the occurrence of cardiac symptoms and can remain elevated for up to 14 days. WebChronic conditions that can produce an elevation of Trop T will rarely show a significant delta over time intervals of 2 to 6 hours.
