  5. Protocol: Acute Coronary Syndrome Evaluation
    1. Older protocol - replaced in United States with Troponin
    2. Obtain Serial CPK every 6 hours for total of 3 values
    3. Fractionate to CK-MB only if CPK increased
    4. CK-MB >5% of total CPK suggests Myocardial Infarction

Creatine Kinase (C0010287)

Definition (NCI) An enzyme complex that can reversibly convert ATP and creatine to phosphocreatine and ADP. Cytosolic creatine kinases are comprised of homodimers or heterodimers of creatine kinase B-type protein and creatine kinase M-type protein. Mitochondrial creatine kinases are octomers comprised of either four homodimers of creatine kinase U-type, mitochondrial protein or four creatine kinase S-type, mitochondrial protein homodimers.
Definition (MSH) A transferase that catalyzes formation of PHOSPHOCREATINE from ATP + CREATINE. The reaction stores ATP energy as phosphocreatine. Three cytoplasmic ISOENZYMES have been identified in human tissues: the MM type from SKELETAL MUSCLE, the MB type from myocardial tissue and the BB type from nervous tissue as well as a mitochondrial isoenzyme. Macro-creatine kinase refers to creatine kinase complexed with other serum proteins.
