High creatine kinase isoenzyme is commonly seen in acute myocardial infarction and myocarditis; it is also seen in skeletal muscle injury.
Creatine kinase isoenzyme (CK-MB) is found mainly in cardiac muscle, but also in skeletal muscle. When creatine kinase isoenzyme is elevated, it often indicates the presence of myocardial injury, such as acute myocardial infarction, myocarditis and other diseases.
When acute myocardial infarction occurs, creatine kinase isoenzyme usually increases within 4 hours after the onset of the disease, reaches a peak in 16 to 24 hours, and returns to normal in 3 to 4 days, and its degree of increase can more accurately reflect the scope of the infarction, and whether the peak occurs in advance can help to determine the success of thrombolytic therapy.
Rarely, elevated creatine kinase isoenzyme is also seen in skeletal muscle injury.
If creatine kinase isoenzyme is elevated, it is necessary to complete the examination in time to clarify the specific cause of the disease, and actively accept the regular treatment to avoid delaying the disease.
