There are many reasons for abnormal myocardial enzymes. For example, acute hepatitis, cirrhosis, liver failure, tumor, acute myocarditis, acute myocardial blockage, myocardial damage caused by infection, as well as exercise-induced muscle damage and muscle damage after training, and even muscle pain caused by trauma will also cause a corresponding increase in myocardial enzymes. Therefore, in general, creatine kinase isoenzyme in myocardial enzyme is specific. For heart disease, strict consideration should be given when it is elevated, and troponin or BNP should be improved. Compared with the clear diagnosis, glutamic oxaloacetic transaminase is relatively poor. Hepatitis and cirrhosis can also be increased. If it is creatine kinase, it will also be higher in sports injury, and the increase is more severe. If it is the increase of lactate dehydrogenase, it is often caused by external factors, or it is more likely to be caused by tumors.
