Clinical Significance

Measurements of Creatine Kinase are used in the diagnosis and treatment of myocardial infarction and muscle disease. Elevated results may be due to myocarditis, myocardial infarction, muscular dystrophy, muscle trauma or excessive exercise. Elevated CK-MB levels are associated with myocardial cell death and damage due to acute myocardial infarction.
