WebMar 2, 2024 · Creatine kinase (CK), also known as creatine phosphokinase, is an enzyme that plays a role in energy production. Higher amounts of this enzyme are found in tissues that use a lot of energy, such as the muscles (including the heart) and the brain [ 1 ]. Creatine kinase will leak into the blood when these tissues are damaged. WebAug 22, 2024 · Other cardiac causes include myocarditis and aortic dissection. Creatine kinase Myocardial muscle creatine kinase (CK-MB) is found mainly in the heart.

WebPhysiology. Creatine kinase (CK) is a “leakage” enzyme present in high concentrations in the cytoplasm of myocytes (skeletal and cardiac primarily) and brain and is the most widely used enzyme for evaluation of muscular disease. In muscles, CK functions by making ATP available for contraction by phosphorylating ADP from phosphocreatine. WebNov 9, 2024 · A creatine kinase-MB (CK-MB) test may be used as a follow-up test to an elevated creatine kinase (CK) in order to determine whether the increase is due to heart damage or skeletal muscle damage.
