CK-MB | Creatine Kinase Heart Isoenzyme

Creatine Kinase Heart Isoenzyme (CK-MB) activity determination is one of the laboratory indicators of myocardial infarction. Unlike troponin T, this indicator does not correlate with the extent of heart muscle damage. CK-MB, similar to troponins, can indicate a myocardial infarction even when the ECG does not show such pathology. Appearance in circulation (from the onset of pain): 2-6 hours, peak release time (from the onset of pain): 12-24 hours, return to normal (from the onset of pain): 7 days.
