According to Yang Zaizhen, director of cardiac macrovascular surgery at Zhengzhou People’s Hospital, for most patients with simple precocious heart disease, the cure rate reaches more than 99% when surgery is done at the age of 1-2. However, families in poor areas often delay treatment until they are teenagers because of information asymmetry or economic reasons, often missing the best time for treatment, which is the main reason for the low consultation rate and high mortality rate of children with precocious heart disease in rural areas. The World Health Organization has proposed the “1000 days of heart health”, which means that precocious heart disease must be treated within 1000 days after birth. Yang Zaizhen, cardiac and macrovascular surgery department of Zhengzhou People’s Hospital, said that it is necessary to establish a “three-tier prevention and treatment” system in the country, and fortunately, this work has been gradually spread in various places. In a nutshell, primary prevention is aimed at prevention of the cause of the disease, secondary prevention is aimed at screening of the disease, and tertiary prevention is the treatment of the disease. Primary prevention is eugenics, which is the reduction or elimination of risk factors for prevalent heart disease according to their causative factors in order to reduce the incidence of prevalent heart disease. For example, too much exposure to radiation during pregnancy, taking some cold and flu antiviral drugs, spending too much time in front of computer screens, and exposure to toxic gases from decorated furniture. The father-to-be may have to start six months before, and the mother-to-be at least three months, so that the child’s heart can avoid the influence of such external teratogenic factors. Secondary level prevention refers to screening for heart malformations detected early during fetal life, mainly fetal echocardiography. That is, prenatal fetal heart screening, which is usually performed during the 22nd to 24th week of pregnancy to detect most of the predilection, and for the fetuses with serious, incomplete correction or unsatisfactory results after treatment detected, the corresponding eugenic advice is given and the pregnancy is terminated in time, which is the current focus of prevention and treatment.” Tertiary prevention means that the child should be detected and diagnosed early after birth for timely treatment. In the third level of prevention, whether it is medical or surgical treatment, the overall diagnosis rate is clearer, and the surgical results are better, and the majority of children have good long-term results. The future life, marriage, childbirth and work will not be greatly affected. However, precordial disease is a four-level discipline, very specialized, parents are advised to take their children to a professional hospital for examination as early as possible, in order to make a clear diagnosis and timely treatment. Consultation telephone: 0371-67077697; 0371-67077553; 18736093289. website: http: //xz.zzrmyy.com
