What is the cause of congenital heart disease in newborns?

A complete family should consist of parents and children. If there were only parents, it would be incomplete. Therefore, the importance of children to a family is self-evident. When a family has a child, some subtle changes occur. It can be said that children are the apple of their parents' eyes. Every parent wants to have a healthy baby, but not all parents can get what they want. Because some babies have congenital heart disease. What is going on? Let us look at the causes of congenital heart disease.

Environmental factors in fetal development:

(1) Infection: Viral or bacterial infection in the first three months of pregnancy, especially rubella virus, followed by coxsackie virus, has a higher incidence of congenital heart disease in infants born to them.

(2) Others: such as amniotic lesions, fetal compression, threatened abortion in early pregnancy, maternal malnutrition, diabetes, phenylketonuria, hypercalcemia, medical use of radiation and cytotoxic drugs in early pregnancy, and maternal age are all likely to cause congenital heart disease in the fetus.

Genetic factors: Congenital heart disease has a certain degree of familial incidence trend, which may be caused by chromosomal aberrations in the reproductive cells of parents. Genetic studies believe that most congenital heart diseases are caused by the interaction of multiple long-term genes and environmental factors.

In addition to the causes mentioned above, the causes of congenital heart disease in newborns may also be related to the geographical environment of the area. For example, the incidence of congenital heart disease in newborns in plateau areas is higher than that in ordinary areas. I hope the above reasons can help some parents prevent the occurrence of the disease.
