Normal values ​​of myocardial enzymes in children

Myocardial enzymes are mainly distributed in the ventricular muscles in our human body. They have their own specific values, and there is also a myocardial enzyme spectrum widely used in medicine. Generally, myocardial enzymes in our human body are in a normal state, that is, normal values. According to surveys, children's myocardial enzyme index is generally higher than that of adults. So today I will give you some information about the normal values ​​of myocardial enzymes in children.

At present, the normal values ​​of myocardial enzyme spectrum are mostly based on adult standards, while the normal values ​​of children are higher than those of adults. Therefore, when you find that your child's myocardial enzyme is slightly higher, don't be too shocked. Don't think that the child has myocarditis just because the myocardial enzyme spectrum value is increased. Because there are many factors that affect the myocardial enzyme spectrum, many hospitals use the measurement of cardiac troponin to assist in the diagnosis of myocarditis. The myocardial enzyme spectrum of most children is 2 to 3 times the normal reference value.

Normal values ​​of myocardial enzymes in children

When myocardial damage occurs in the human body, myocardial enzymes will increase to varying degrees. However, the current normal values ​​of myocardial enzyme spectra are mostly adult standards. In fact, the normal values ​​of children are higher than those of adults. Therefore, do not assume that a child’s myocardial enzyme spectrum value is increased if it means he or she has myocarditis. Since there are many factors that affect the myocardial enzyme spectrum, many hospitals use the measurement of cardiac troponin to assist in the diagnosis of myocarditis. The myocardial enzyme spectrum of most children is 2 to 3 times the normal reference value.

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. Myocardial enzyme spectrum refers to a group of enzymes related to myocardial damage. Currently, most domestic hospitals test myocardial enzymes including LDH, CK-MB, α-HBDH, and GOT. This group of related enzymes has a certain auxiliary effect on the diagnosis of myocardial damage in children.

At present, it seems that the high myocardial enzyme levels in children are mostly due to the reference to adult standards. The first thing that everyone should make clear is that if there are no corresponding symptoms and signs, a slight increase in certain indicators in the myocardial enzyme test has no clinical significance.

In fact, according to the analysis of high myocardial enzyme spectra in children by many medical institutions in recent years and domestic and foreign literature research, it is found that 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.

There is also a set of specific research data, which shows 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%.

Therefore, the conclusion is that only when the values ​​in the myocardial enzyme spectrum increase significantly and exceed the above-mentioned allowable range do they have clinical value. Therefore, when doctors encounter the test results of elevated myocardial enzyme spectrum in children, they generally make judgments based on clinical manifestations. If other physical examination results are normal and there are no other special symptoms or signs, doctors will think that it is normal for certain myocardial enzyme spectra to be elevated.
