A:   CK is an enzyme called creatine kinase or creatine phosphokinase. CK can be measured in the laboratory and elevation of CK is an indication of damage to muscle. Elevated lab levels of CK can help diagnose several medical conditions including: rhabdomyolysis (severe muscle breakdown), myocardial infarction (heart attack), muscular dystrophy, myositis (inflammation of muscle), myocarditis (inflammation of heart muscle), malignant hyperthermia, and neuroleptic malignant syndrome.
