Higher creatine kinase isoenzyme may gradually decrease after the causative factor is removed by medication, surgery, or other related treatments for the primary disease.
Creatine kinase isoenzyme is commonly found in heart diseases such as myocardial infarction, angina pectoris, myocarditis, etc. It can also be elevated in skeletal muscle diseases, myasthenia gravis, or after undergoing surgery.
Therefore, it is necessary to treat the primary disease with medication or surgery, such as coronary stenting for myocardial infarction to open up the infarcted blood vessel, etc., and the enzyme level can be reduced only after the disease is relieved.
In the case of physiological elevation, such as after fitness or strenuous exercise, the level can often be restored to normal after sufficient rest and retesting.
Therefore, it is recommended to consult a doctor and receive standardized treatment when necessary.
