Normal values for creatine kinase range from 18 U/L to 198 U/L. If creatine kinase shows more than a threefold elevation, the risk is greater. More than 10 times the normal value is usually more serious. It may be caused by myocarditis, myocardial infarction, etc. The cause needs to be identified and treated in time. 1. Myocarditis: Myocarditis will cause creatine kinase to rise more than 10 times the normal value, and will also cause creatine kinase isoenzyme, glutamate aminotransferase and other indicators to rise. At this time, it is necessary to go to the hospital in time for electrocardiogram and other related examinations to further clarify the diagnosis. If it is caused by myocarditis, you need to use adenosine triphosphate, coenzyme A and other drugs for treatment. 2. Myocardial infarction: Myocardial infarction will lead to large-scale necrosis of cardiomyocytes, and cardiac enzymes will be released into the bloodstream, resulting in elevated serum myocardial enzymes, and when the situation is serious, creatine kinase will be more than 10 times the normal value of the phenomenon. If it is caused by myocardial infarction, you can take oral propranolol, bisoprolol and other drugs for treatment. If the increase of creatine kinase is more than three times, and the increase of creatine kinase is accompanied by the increase of troponin, it is relatively more dangerous, and we need to go to the hospital in time for further examination, clear diagnosis and treatment.
