What is the normal value of myocardial enzymes in children?

The normal values of myocardial enzymes in children will vary depending on many factors, including detection methods, age, gender, etc. In general, aspartate aminotransferase (AST) is less than or equal to 40 units/L, lactate dehydrogenase (LDH) is less than or equal to 250 units/L, creatine kinase (CK) is less than or equal to 25 units/L, and creatine kinase isoenzymes (CK-MB) is less than or equal to 25 units/L. Normal values of myocardial enzymes in children may vary depending on the test method, age, sex, etc. The following are the normal reference ranges for myocardial enzymes in children under normal circumstances: 1. Aspartate aminotransferase (AST): less than or equal to 40 units/L. 2. Lactate dehydrogenase (LDH): Less than or equal to 250 units/L. 3. Creatine Kinase (CK): Less than or equal to 25 units/L. 4. Creatine Kinase Isoenzyme (CK-MB): less than or equal to 25 units/L. It should be noted that these normal values are for reference only, and the specific values should be judged according to the reference range provided by the hospital or testing institution. If the child's myocardial enzyme test results are abnormal, the doctor may make comprehensive analysis and diagnosis in combination with clinical symptoms and other test results. In addition, elevated myocardial enzymes may also be associated with a variety of diseases, such as myocarditis, myocardial infarction, cardiomyopathy, etc. If you suspect a child has a heart-related disease, you should seek medical attention in time for further examination and treatment. For special populations, such as newborns, premature infants, myocardial enzyme normal values may be different from adults. The doctor will assess and judge according to the specific circumstances. Myocardial enzyme examination in children, but also need to pay attention to some matters, such as whether to need an empty stomach before the examination, whether to need to rest, etc. Parents should follow the doctor's guidance, do the preparatory work before the examination. In short, the normal value of myocardial enzyme in children is a relative range, the specific value needs to be based on the hospital or testing institutions to judge the standard. In case of doubt about the results of myocardial enzyme test in children, consult your doctor in time for further diagnosis and treatment.
