CK-MB | Cardiac isoenzyme of creatine kinase

Determination of creatine kinase cardiac isozyme (CK-MB) activity is one of the laboratory indicators of myocardial infarction. This indicator, unlike troponin T, does not correlate with the extent of damage to the heart muscle. CK-MB, similarly to troponins, can indicate myocardial infarction even when the ECG does not show such pathology. Appearance in the bloodstream (from the onset of pain): 2-6 hours, maximum release time (from the onset of pain): 12-24 hours, return to normal (from the onset of pain): 7 days.
