In recent years, the prevalence of congenital heart disease (hereinafter referred to as: congenital heart disease) has increased at an accelerated rate, according to information, China’s annual increase of ????? ?300,000 cases of congenital heart disease, which is currently the first cause of death of children under 5 years old in China. Genetics, drugs taken by women during pregnancy, infection with viruses, environmental pollution, and radiation can cause abnormal fetal heart development. In particular, rubella virus infection in the first trimester of pregnancy can sharply increase the risk of the child developing precocious heart disease. So, what efforts should the mother-to-be make to reduce the incidence of precocious heart disease? Drugs and viruses are the most important causes of precocious heart disease There has been a misconception that precocious heart disease is mostly due to genetics. According to the data, there are many causes of congenital heart disease, genetic factors only account for about 8%, while the vast majority of 92% are caused by environmental factors, such as women taking drugs during pregnancy, infection with viruses, environmental pollution, radiation, etc. can cause abnormal fetal heart development. Therefore, the acquired factors are the biggest killers of precocious heart disease, especially the physical condition of the mother-to-be during pregnancy, medication, living environment and other factors. Exposure to teratogenic drugs such as lithium, sodium phenytoin or steroids in early pregnancy can lead to a 2% prevalence of fetal precocious heart disease. Excessive exposure to radioactive substances, such as X-rays and isotopes, in early pregnancy can also increase the prevalence of precocious heart disease. There are also some high-risk factors that can cause fetal heart disease. factors can also lead to an increased risk of fetal precocious heart disease. Viral infections during the first trimester, especially during the third to eighth weeks of pregnancy, can predispose the fetus to cardiovascular malformations. The rubella virus is the main culprit of fetal precocious heart disease. In addition, influenza, mumps, coxsackie virus, herpes virus, etc. are also often the “perpetrators” of pediatric precocious heart disease. In addition, pregnant women with diabetes and gestational diabetes have a 2% risk of fetal precocious heart disease if their blood sugar is not controlled during pregnancy, so the risk of fetal precocious heart disease should be reduced by keeping blood sugar levels stable in early pregnancy. To prevent gestational diabetes, in addition to a reasonable diet and weight control during pregnancy, moderate exercise is also necessary for the mother-to-be. The director of cardiovascular surgery at Greentown Cardiovascular Hospital, Zhu Chest Kai, said: the mother-to-be can be screened for simple congenital heart disease with ultrasound examinations during pregnancy, and the best period for fetal echocardiography exploration is from 20 weeks to 28 weeks.? The mother-to-be to prevent congenital heart disease? What are the methods: First, communicate more with your obstetrician in everything; first, communicate more with your doctor. Although it sounds a bit clichéd, it is very practical and effective. Mothers-to-be need to go to the hospital regularly to check if they are suffering from diabetes, measles and flu? and other illnesses, and take care of them as early as possible under the guidance of a doctor. Women with serious illnesses such as diabetes and ketonuria phenylpropionate have a higher than normal chance of having a fetus with congenital heart disease. Therefore, daily attention should be paid to avoid some bad habits, such as taking a hot bath, smoking, drinking alcohol or large amounts of coffee and cola, which can easily lead to fetal malformations. Secondly, the daily intake of a certain dose of ? folic acid; secondly, women are required to take a variety of vitamins daily, including 400 mg of folic acid and folic acid supplements. Folic acid is effective in preventing congenital heart disease, and it is also known for its role in preventing neural tube abnormalities, and women should preferably take proper supplements in the first three months of pregnancy. It is also very important to consult your doctor at all times about the use of medication, which largely prevents the possibility of fetal malformations due to indiscriminate use of drugs. This is especially important for Chinese people who are used to buying their own medication for health care. Thirdly, avoid contact with people with influenza; stay away from people with influenza and other diseases that can easily cause fever. The recent flu epidemic is serious, and as a mother-to-be, it is important to protect yourself because in the first trimester, any illnesses associated with fever can easily cause fetal defects. associated illnesses are likely to cause a double risk of heart disease in the fetus. Fourth, the use of any medication should be discussed with your doctor, even if it is over-the-counter. Finally, if a child is diagnosed with congenital heart disease at birth, there is no need to worry too much, as medical technology has now reached a certain high level and the average congenital heart disease? If the child is treated in time, he or she can recover and be as healthy as a normal person. However, it should be stressed that if the diagnosis of precocious heart disease must be done early to avoid missing the best time for treatment. Fifth, it is best to choose to have a baby before the age of 35,? If this is not possible, it is recommended that pregnant women of advanced age receive strict perinatal medical observation and care. Pregnant women should be exposed to as few adverse environmental factors as possible, such as radiation and electromagnetic radiation. Make good preparation for pregnancy and terminate smoking and drinking habits in advance. Have regular maternity checkups, you can have an ultrasound in the middle and late stages of pregnancy for early detection of fetal heart problems.
