The most common CPK enzyme test is CPK-2 (CPK-MB) which is released from the heart following myocardial infarction. Peak levels occur sometime between 12 and 24 hr following injury. Serial CPK-2 measurements are monitored in patients with suspected myocardial infarction, as well as patients with cardiac contusion from chest trauma, open-heart surgery, or myocarditis.
