What is the normal value of myocardial enzyme in infants?

When a baby is just born, his body is not fully developed yet. It cannot be said that the baby is fully developed in the mother's belly, so parents still need to pay attention to all aspects of the baby's physical condition. Therefore, some parents want to know what the normal value of the baby's myocardial enzyme is, so that it is easier to judge. Let me give you a detailed introduction below, let’s take a look together.

Normal values ​​of myocardial enzymes in newborns

Examination of myocardial enzymes is mainly used to determine myocardial ischemia and necrosis or cell membrane permeability. The normal reference values ​​of myocardial enzyme spectrum are mostly adult standards, while the normal reference values ​​of newborns are higher than those of adults. Therefore, do not assume that an increased myocardial enzyme spectrum value in a newborn means that the baby has myocarditis. Since there are many factors that affect the myocardial enzyme spectrum, cardiac troponin is measured to assist in the diagnosis of myocarditis. The myocardial enzyme spectrum of most children is 2 to 3 times the normal reference value.

So, what is the normal value of myocardial enzyme in newborns?

Myocardial enzyme spectrum refers to a group of enzymes related to myocardial injury. 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 neonatal myocardial injury.

The reference values ​​of myocardial enzyme spectrum in newborns are higher than those in adults. The reference values ​​of myocardial enzyme spectrum in newborns are:

1. Creatine kinase: (115±82)U/L;

2. Creatine kinase isoenzyme (19±13) U/L;

3. Aspartate aminotransferase (32±15) U/L;

4. Lactate dehydrogenase (263±113) U/L;

5. α-Hydroxybutyrate dehydrogenase (246±114) U/L.

How to maintain normal values ​​of myocardial enzymes in newborns

Currently, the normal values ​​of myocardial enzymes are mostly based on adult standards, while the normal values ​​of myocardial enzymes in newborns are higher than those in adults. Therefore, do not assume that an increase in the myocardial enzyme spectrum values ​​in newborns means that they have myocarditis. How can we keep the values ​​of myocardial enzymes in newborns within the normal range?

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. For children with more severe myocarditis, echocardiography can be performed to detect enlargement of the heart chamber and decrease in cardiac function. For children with complex diseases, myocardial and endocardial biopsy may be performed to confirm the diagnosis if necessary.

In order to maintain normal values ​​of myocardial enzymes in newborns, it is recommended to cooperate with doctors for active treatment. In newborn care, it is important to ensure adequate bed rest and avoid strenuous activities; the diet should be nutritious, easily digestible, high in calories, fiber, vitamins, protein, and fat, with small meals and frequent meals, avoiding overeating and irritating foods to avoid increasing the burden on the heart; keep bowel movements open to prevent constipation.

As for the question of what is the normal value of infant myocardial enzyme, a very detailed introduction has been given above. In this way, there will be no problems caused by ignorance. At the same time, it can also better introduce some similar knowledge about infant myocardial enzymes, which will be of great help in taking care of the baby.
