How is congenital heart disease inherited in children?

Many people are very curious about the inheritance of congenital heart disease, because some young people with a family history of congenital heart disease feel powerless to get married and have children for this reason, and are afraid that their family history of congenital heart disease will affect their children. So today we will explain to you how congenital heart disease is inherited in children?

Let's take a look at how much congenital heart disease in children is related to genetics:

Congenital heart disease is related to genetic factors. The probability of a mother with a direct relative with congenital heart disease giving birth to a child with congenital heart disease is significantly higher than that of the normal population. However, this inheritance mode is different from single gene genetic disease, which only increases the risk. The occurrence of congenital heart disease is also related to radiation exposure during pregnancy, drugs, viral infections, etc.

Inheritance refers to the phenomenon that parents and children are extremely similar in morphological structure and physiological function characteristics. Many studies have shown that congenital heart disease has a clear familial tendency. The prevalence of congenital heart disease in siblings and children of congenital heart disease is 10 to 14 times higher than that of children in the general population. If parents have congenital heart disease, the prevalence of their children is 2% to 5%. If there are already two children with congenital heart disease, the chance of recurrence can be as high as 10% to 15%. Congenital heart disease occurring in the same family can be of the same type or of different types. From these phenomena, congenital heart disease is related to heredity and has a certain genetic tendency, but it does not show a certain genetic law and cannot be called a genetic disease.

Through the above introduction, I believe everyone knows how much congenital heart disease is related to heredity. I hope our work can help people in need, and I also hope that everyone can have a correct understanding of congenital heart disease in children. Let's talk about how to prevent the occurrence of congenital heart disease in children:

Medical science has proven that pregnant women over 35 have a significantly increased risk of fetal genetic abnormalities. Therefore, it is best to give birth before the age of 35. If this is not possible, it is recommended that older pregnant women must undergo strict perinatal medical observation and health care.

If the expectant mother has habits such as smoking and drinking, it is best to stop at least six months before pregnancy.

Especially in the early stages of pregnancy, we should actively prevent rubella, influenza and other rubella viral diseases. Pregnant women should try to avoid taking medications. If they must use them, they must be taken under the guidance of a doctor.

During pregnancy, try to avoid exposure to adverse environmental factors such as radiation and electromagnetic radiation. Avoid traveling to high-altitude areas during pregnancy because it has been found that the incidence of congenital heart disease in high-altitude areas is significantly higher than that in plains, which may be related to lack of oxygen.
