As a cardiac marker, Troponin T is highly sensitive for myocardial damage. In cases of acute myocardial infarction (AMI), Troponin T levels in serum rise about 3 to 4 hours after the occurrence of cardiac symptoms and can remain elevated for up to 14 days.1
Troponin T is an independent prognostic biomarker which can predict the near-, mid- and even long-term outcome of patients with acute coronary syndrome (ACS). Patients with ACS and elevated levels of Troponin T and/or the cardiac enzyme CK-MB are considered to have experienced a non-ST-elevation MI (NSTEMI); whereas the diagnosis of unstable angina is established if Troponin T and CK-MB are within the reference range
