First of all:

Clinically, it is mainly used to diagnose myocardial infarction. 2-4 hours after the onset of myocardial infarction, the content of creatine kinase in blood will increase. The activities of aspartate transferase and lactate dehydrogenase in serum changed earlier than those in serum.

Second:

The content of creatine kinase in children with malnutrition, polymyositis and muscle injury can also increase. In severe angina pectoris, pericarditis, atrial fibrillation, cerebrovascular accident, meningitis and heart surgery, the content of creatine kinase will also increase.

Third:

Viral myocarditis, creatine kinase can also be increased, which has a certain impact on the later diagnosis.

Second, matters needing attention

People with high creatine kinase should pay attention to doing appropriate activities in their lives, such as walking or jogging, and go to the hospital for physical examination regularly, hoping to help everyone.

Creatine kinase is an enzyme released by muscle, and the obvious increase of creatine kinase indicates the destruction of muscle. The increase of creatine kinase must first rule out the possibility of myocardial necrosis, such as myocardial infarction and myocarditis. Creatine kinase can be significantly increased, accompanied by chest pain, chest tightness, breath holding and palpitation. The content of creatine kinase in muscle is very large. If other muscles such as skeletal muscle are injured, creatine kinase will increase significantly. For example, the increase of creatine kinase, in the case of excessive fitness, fatigue and mountain climbing, is often accompanied by symptoms of muscle pain in limbs, which is a common symptom of excessive creatine kinase.
