Precocious heart disease brings great pain and heavy burden to the affected children and their families, and even to the whole society, which cannot be ignored. Despite the current high level of treatment for precocious heart disease in China, we still urge parents should grasp the three ‘early’ to prevent precocious heart disease. The first one is to get married early and have children early, and not to be a senior mother. Clinically, women who get pregnant after the age of 35 have a higher chance of having a child with precocious heart disease, so married women should be encouraged to have children at the right age to protect the health of their children. The second early, is to pay attention to early pregnancy health care. Many congenital heart diseases are related to viral infections in the first trimester of pregnancy, which is the process of fetal heart development; secondly, pay attention to the prevention of diseases such as colds and rubella, stay away from pollutants and all kinds of radiation, do not live in a house that has just been renovated, and do not take medication on your own once you get sick to prevent the adverse effects of drugs on fetal heart development, and always consult your doctor with medication. This should become the main preventive measure in preventing congenital heart disease. The third early is that once a newborn is found to have congenital heart disease after delivery, treatment should be given “before it’s too late”. The best time to treat congenital heart disease varies according to the condition of the child, some two months, some one year old, some may need to be a little older, but the general principle of treatment is the earlier the better, the specific time of surgery or to listen to the doctor, some parents feel sorry for their children, thinking that “surgery is risky, maybe the disease will slowly get better when they grow up”, this idea is wrong and dangerous. This idea is wrong and dangerous, surgery for precardiac disease is now a relatively mature surgical procedure, after the operation of children with precardiac disease may live like healthy children, should not be because of the child’s heartache and delay the best treatment time. Parents need to pay attention to the fact that once a child is found to have a precordial disease, they must keep their mouths shut and not talk about the child’s disease with people around them, so as not to cause psychological pressure on the child, for patients with precordial disease, even more complicated surgery doctors have done, but for children, the psychological burden is often a lifelong thing, parents should not let the child cure the heart disease, but add to the heart disease.
