What is the normal value of myocardial enzyme in newborns?

Myocardial enzyme is an important indicator for checking myocardial damage. Normal myocardial enzyme indicates good heart function. If the myocardial enzyme is a little high, it means that there are some problems with the heart and the patient needs to be sent to the hospital for examination in time. However, our examination of myocardial enzymes is related to adults. However, due to the different physiques of newborns, the values ​​of myocardial enzymes in newborns are basically higher than those in adults. But many parents are not very clear about this. When they find that the myocardial enzymes are higher than the normal values ​​in adults, they will feel very worried. So what are the normal values ​​of myocardial enzymes 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.

High myocardial enzyme levels are a condition that many newborns will encounter. 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 required 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.

From the above data, we can know the normal value of myocardial enzyme in newborns. So when the baby is born, there is no need to worry if the myocardial enzyme is slightly higher than that of adults. However, in daily life, we should pay attention to the healthy and nutritious diet of the newborn. The baby should eat small meals frequently for easy digestion. Also, if parents are worried about their children's high myocardial enzyme levels, they should immediately send their children to a regular hospital for examination to understand the specific situation.
