. CK isoenzymes are subtypes of the creatine kinase analyte. The CK-MB
(creatine kinase myocardial band) isoenzyme is a specific marker for heart muscle damage. The CK-MB levels will start to rise in the bloodstream approximately 4 hours after a myocardial infarction, and will peak approximately 18 hours after the event. Troponin levels will be elevated with heart muscle damage, but not with other types of muscle trauma. Troponin I levels are especially sensitive to myocardial damage.
