Creatinine (CK) has three isoenzymes. These are, CK-MM, CK-MB and CK-BB. CK-MM is spesific to skeletal muscle, CK-MB is spesific to myocardial muscle and CK-BB is spesific to brain and lungs. When any of these tissues are damaged, they are released in blood.
Interpretation: If CK is found high in blood and no kidney failure is diagnosed, an overproduction is suspected. This test is done to specify the site of the overproduction. CK-MB (CPK 2) levels rise in 3-6 hours after the heart attack. The level peaks at 12-24 hours and returns to normal 12-48 hours after tissue death. It also increases in electrical injuries, heart defibrillation (purposeful medical heart shocking), inflammation of the heart muscle(myocarditis) and open heart surgery.
