Cardiac enzymes markers assay diagnosis

The most important test is Troponin

Preferred marker for diagnosis of Cardiac injury

Repeated after 6-12 hours

Elevation of CK-MB and troponin indicates Acute Myocardial infarction

Elevation of Troponin alone indicates minor myocardial damage

Elevation continues for up to 2 Weeks

Importance of measuring Myoglobin marker is not important at all
