Is myocardial damage serious after a newborn cold?

Newborns will develop many adverse symptoms after catching a cold, but many people don’t understand the harm this will cause. Newborns sometimes show symptoms of myocardial damage after catching a cold, but many people may delay the treatment of symptoms due to lack of knowledge in this area. We need to learn about this knowledge. So is myocardial damage serious after a newborn catches a cold? Let's take a look at how authoritative experts answer this question.

In clinical practice, myocardial damage is only a general concept, not an accurate name of a disease. Doctors often use it to diagnose when the myocardium is damaged but not as severe as myocarditis. The damage is mostly temporary or transient and reversible, and most of them have a good prognosis.

1. We know that myocardial enzymes and isoenzymes are one of the effective means for early diagnosis of myocardial damage. The following indicators are commonly found in test reports: GOT (aspartate aminotransferase), CK (creatine kinase), CK-MB (creatine kinase isoenzyme), and LDH (serum lactate dehydrogenase). When myocardial cells are damaged, one or more of these enzymes may be elevated. However, the presence of myocardial damage or myocarditis cannot be determined based on an increase in just one or two of the above items. A comprehensive analysis based on clinical manifestations is also required.

2. CK is widely present in muscles, mainly skeletal muscles. The myocardium contains only half of the skeletal muscle. It is also found in tissues such as the brain, small intestine, liver, spleen, and lungs. LDH is also widely distributed in the body. Both enzymes can be released into the blood under pathological damage. Although they have high sensitivity, their specificity is poor.

3. GOT (aspartate aminotransferase), also known as aspartate aminotransferase, is most abundant in myocardial cells. Therefore, when myocardial cells are damaged, a large amount of enzyme is released into the blood, increasing the serum content. It is generally used as an auxiliary examination for myocardial infarction and myocarditis in clinical practice, but its serum concentration may also increase when the liver is damaged. When alanine aminotransferase (ALT) is significantly elevated and the alanine/aspartate ratio is >1, it indicates damage to the liver parenchyma. CK-MB and LDH-1 isoenzymes are myocardial cell-specific isoenzymes, with high levels in myocardial cells. In particular, elevated CK-MB indicates myocardial damage, which has high specificity and sensitivity.

4. Recent studies have shown that troponin I (CTnI) is a reliable indicator for determining myocardial damage and is significantly superior to CK-MB, which is worthy of reference for clinical physicians. However, the above tests are just some data after all and cannot replace doctors. Clinical diagnosis requires a comprehensive assessment by doctors based on medical history and physical examination results.

5. In clinical practice, we found that among all children with colds, nearly 50% had transient myocardial damage. When the children's indicators were checked again 2 weeks later, they returned to normal. Only 3% of children are likely to develop severe symptoms and develop viral myocarditis, requiring hospitalization.

6. Parents are reminded that everything has two sides. On the one hand, parents should not regard colds as daily minor illnesses and take lightly the abnormal symptoms of their children (such as chest tightness, long sighs, pale complexion, etc.). If any abnormality is found, the child's myocardial enzymes (fasting test required) and troponin should be tested as soon as possible. On the other hand, if some indicators in the test are elevated and the doctor diagnoses it as myocardial damage, it means that the condition is not serious for the time being and there is no need to be overly nervous. Cooperate with the doctor's treatment and observe the situation dynamically.

Is myocardial damage serious after a newborn catches a cold? Through the above content, we have learned some useful information. We all know that the harm of myocardial damage after a newborn cold is very serious. This symptom can also lead to more serious illness if left untreated. Therefore, in life we ​​must take good care of our children's physical health. Finally, I wish all the sick newborns a speedy recovery and a healthy life!
