What is the cause of high myocardial enzymes in children?

Children's health issues have always been the most important concern for parents, but sometimes when we do examinations, we will find that when testing the myocardial enzyme spectrum, the test results will often show an upward arrow, which means that it is slightly higher than the reference value of the test index. Why is this? Today, the editor will introduce what is going on with high myocardial enzymes in children. Parents who are interested can take a look together.

Since the current normal range of myocardial enzyme testing for children is based on adult standards, if there are no corresponding symptoms and signs, a slight increase in certain indicators in myocardial enzyme testing has no clinical significance.

In recent years, many medical institutions have conducted statistical analysis on the high myocardial enzyme spectrum in children, and domestic and foreign literature has also reached a clear conclusion: the myocardial enzyme spectrum values ​​of children are generally higher than those of adults, and the younger the age, the higher the myocardial enzyme spectrum.

It is reported that the percentage increases in the upper limits of various enzymes in children compared with the reference values ​​of the adult myocardial enzyme spectrum are: CK (creatine kinase) and AST (aspartate aminotransferase) increase by about 15%, CK-MB (creatine kinase isoenzyme) increase by about 30%, LDH (lactate dehydrogenase) and HBDH (hydroxybutyrate dehydrogenase) increase by about 90%.

Generally speaking, the myocardial enzyme spectrum has clinical value only when its values ​​increase significantly and exceed the above-mentioned allowable range. When children's myocardial enzyme test results are elevated, doctors will generally decide whether further examination or clinical intervention is needed based on the clinical manifestations. Usually, if other physical examination results are normal and there are no other special symptoms or signs, doctors will consider it normal for certain elevated myocardial enzyme spectra to be normal. For example, LDH (lactate dehydrogenase) and HBDH (hydroxybutyrate dehydrogenase) have a large fluctuation range and are affected by many factors, so a slight increase is of little significance.

After reading the editor's introduction about high myocardial enzymes in children, do parents have a certain understanding? At the same time, the editor would like to remind everyone that if the child is in good spirits and has a good appetite, parents do not need to take the child for repeated examinations just because certain values ​​of the myocardial enzyme spectrum in the physical examination report are slightly elevated, and there is no need to have unnecessary mental stress.
