What is the reason for poor fetal heart development?

Among the babies born every year in our country, 7‰-11‰ have congenital cardiovascular anomalies. Every pregnant mother wants to give birth to a healthy, smart and beautiful baby, and the development of the fetal heart is a crucial link. How to help the healthy development of the fetal heart during pregnancy is a question that every pregnant mother is very concerned about. So, what factors are mainly affected by the development of the fetal heart? What can be done to help the fetal heart develop well and avoid poor fetal heart development? What about the good situation? 1. What factors affect fetal heart development? A. Genes, derived from family inheritance. If the first child born to a mother has congenital heart disease, the probability of the second child having congenital heart disease is about 2%; if two consecutive children have congenital heart disease, the probability of subsequent children with congenital heart disease may increase to 10%. If the mother has congenital heart disease, the risk of the second generation suffering from congenital heart disease is 10%. B. Pregnant women suffer from diseases during pregnancy or suffer from viral infections during pregnancy. If a pregnant woman has diabetes and the condition is not treated and controlled, the risk of fetal congenital heart disease is 2%. If the condition is controlled stably in early pregnancy, the risk decreases. If a woman is infected by a virus in the first three months of pregnancy, especially between 3 and 8 weeks of pregnancy, the fetus is prone to cardiovascular malformations. Rubella virus is the main culprit causing congenital heart disease in fetuses; influenza, mumps, coxsackie virus, herpes virus, etc. are also often the \”perpetrators\” of congenital heart disease in children. C. Pregnant women are affected by adverse external environments during pregnancy. Pregnant women exposed to teratogenic drugs in early pregnancy, such as lithium, phenytoin or steroids, can lead to a prevalence of fetal congenital heart disease of up to 2%. Excessive exposure to radioactive substances such as X-rays and isotopes in early pregnancy may cause fetal cardiac dysplasia. D. Personal habits of pregnant mothers and expectant fathers. The incidence of congenital heart disease in infants is twice that of infants born to smoking mothers than to non-smoking mothers. Couples who \”conceive in the same room after drinking\” will cause chromosomal abnormalities in the fetus, and most of the babies born with alcoholism will be accompanied by cardiovascular abnormalities. 2. What can we do to help the fetal heart develop well and avoid poor fetal heart development? Before introducing the method, let us first understand the key time points of fetal heart development: in the second week of pregnancy, the embryonic heart begins Eruption, the interatrial septum is formed in the 5th week of pregnancy, and the ventricular septum is formed in the 8th week of pregnancy, completing the development of the four-chamber heart. After entering the 6th week of pregnancy, the heart has begun to divide the ventricles, beat regularly and begin to supply blood. Pregnancy Entering the 7th week, the embryo\’s heart has been divided into the left atrium and the right ventricle, and begins to beat regularly. At 9 to 10 weeks of pregnancy, unique valves are formed at the outlets of the atria and ventricles. At 11 weeks of pregnancy, with the help of instruments You can hear the rapid beating of the fetal heart. At 17 weeks of pregnancy, the fetal heart development is almost complete, and the heartbeat is strong, about 145 beats/minute. In other words, the critical time point for fetal heart development is from the 2nd week of pregnancy to the 17th week of pregnancy. Taking measures during this time period can better help the fetal heart develop well. It is recommended that pregnant mothers help the fetal heart develop well from the following aspects:: A. Maintain good personal habits. Good habits should be cultivated from the time of pregnancy preparation, such as eating on time, going to bed early and getting up early, exercising more, not smoking or drinking, and regularly supplementing folic acid, so that the expectant father and himself can be in good condition, improve the quality of sperm and eggs, and after pregnancy, Mothers should pay more attention to their work, rest and diet. They should still insist on supplementing folic acid in the first three months and stay away from all kinds of radiation and rays. If the expectant father has the habit of smoking, please try to stay away from the pregnant mother. B. During the critical period of fetal heart development, add more nutrients that are beneficial to fetal heart development. Calcium, copper, phosphorus, and thiamine are the four major nutrients that are crucial to fetal heart development. Milk contains calcium and phosphorus, the recommended daily amounts of which are 1000mg and 700mg respectively; at least 1mg of copper per day in foods such as cashews and kidney beans; about 1.4mg of thiamine per day is necessary, while oats, peas and most of meat products contain thiamine. C. While supplementing the elements needed for fetal heart development, you should limit the excessive intake of certain elements. For example, limit your fat intake, which should be less than 30% of your total daily calories; cholesterol and sodium intake. The intake should be less than 300mg and 3000mg per day respectively. Avoid some food additives and chemicals, such as MSG, and avoid excessive salt intake. Although the level of science and technology and medical care in our country is developing very rapidly, and some fields have reached the top international level, there are still many shortcomings. In some areas with slower development, the medical level still needs to be improved. Therefore, during pregnancy, pregnant mothers still need to Pay more attention and understand some common sense and methods that can help fetal heart development, which will be of great help in giving birth to a healthy baby!
