Cardiac enzymes mainly include creatine kinase (CK), creatine kinase isoenzyme (CK-MB), lactate dehydrogenase, glutamate transaminase, and glutamic oxalacetic transaminase. High cardiac enzymes indicate that the patient’s cardiac enzyme index exceeds the normal range. There are many causes of high cardiac enzymes, such as myocardial cell necrosis as well as injury, acute myocardial infarction, acute myocarditis and other cardiogenic diseases. The specific description is as follows: 1. Myocardial cell damage: CK-MB is mainly derived from the myocardium, so when myocardial enzyme is elevated, it mostly indicates myocardial cell damage or necrosis, which is common in cardiogenic diseases such as acute myocardial infarction and acute myocarditis. After myocardial cell necrosis, the intracellular enzymes will be released into the blood, and through some existing tests, elevated creatine kinase isoenzyme (CK-MB) can be detected in the whole myocardial enzyme spectrum, which is very accurate for early diagnosis of acute myocardial infarction. In addition, it should also be combined with the patient’s clinical symptoms as well as troponin I, troponin T, and dynamic evolution of ECG for comprehensive judgment; 2. Skeletal muscle injury: If CK is significantly elevated, it may be due to skeletal muscle injury, such as acute and chronic muscle injury, fracture or surgery causing muscle cell damage, etc. causing elevated creatine kinase, and creatine kinase is an important indicator in cardiac enzymes, so it may also lead to 3, liver cell damage: such as toxic hepatitis, liver cirrhosis or serious malignant tumors caused by liver cell damage, which causes lactate dehydrogenase, glutamic aminotransferase, glutamic oxalacetic aminotransferase elevation, which is manifested as high cardiac enzymes; 4, other: in addition to the above, high cardiac enzymes may also be other systemic diseases, if it is biliary tract diseases, such as biliary obstructive jaundice, biliary heart syndrome, and cerebrovascular Diseases, endocrine diseases, malnutrition and anemia can all cause elevated cardiac enzymes. Therefore, elevated cardiac enzymes must be taken seriously, and you should seek professional medical help as soon as possible to determine the cause of elevated cardiac enzymes and take targeted treatment.
