A brief description of the dangers of congenital heart disease Congenital heart disease has become an urgent social problem facing the treatment of heart disease in China, and the government has introduced policies to help common children with congenital heart disease, and many charitable organizations have also extended a helping hand to these poor children. What kind of impact does congenital heart disease have on these children and their lives? The first thing that congenital heart disease endangers is the life of the patient. According to the American Heart Association, 30% of childhood deaths are due to congenital heart disease, and the number of deaths from congenital heart disease is nearly twice as high as the number of deaths caused by childhood tumors. Due to the lack of effective prevention methods for congenital heart disease, coupled with the fact that half of untreated congenital heart disease will die by age 1 and 2/3 by age 2, even if they can grow into adulthood, their average life expectancy is much shorter than the average life expectancy of our population, which is about 40 years or so. Some congenital heart disease malformations are more serious, such as intact septal transposition of the great arteries, pulmonary atresia, aorto-pulmonary window, and double outlet of the ventricles, and most children die in the neonatal period, shortly after birth, so these diseases need to be detected and treated surgically as early as possible. The other part of precordial disease is not life-threatening, but due to poor cardiac function caused by heart malformation, large intracardiac shunt or systemic hypoxia, the physical and intellectual development of the infant is affected, and the infant shows difficulty in feeding or refusal to feed, choking and coughing, often eating and stopping, shortness of breath, pallor and breath-holding. Normal infants gain 0.6 kg per month in the first six months of their first year, and 0.5 kg per month in the second six months. Weight growth below this rate indicates delayed development, some serious children may appear anemia and malnutrition, older children often complain of easy fatigue, poor physical strength, sweating, and even chest pain, syncope; or due to pulmonary blood caused by repeated respiratory infections, recurrent bronchitis, pneumonia, also need timely surgical treatment, or serious death from infection-induced respiratory failure and heart failure; another category Another situation is the occurrence of pulmonary hypertension, in which a large number of left-to-right shunts can remain asymptomatic in some patients, but by the time of diagnosis, severe pulmonary hypertension has been combined, at which time most children have lost the opportunity for surgery or the best time for treatment, and immediate and reluctant surgery is extremely risky and has poor long-term results. Furthermore, if congenital heart disease is not effectively treated, it may cause brain abscess due to frequent infection and hypoxia, which may lead to headache, vomiting and convulsions in mild cases due to intracranial hypertension, and affect the patient’s intelligence and general motor coordination in severe cases. Damage to the blood system leads to coagulation dysfunction, which is manifested by a tendency to bleed and a tendency to develop symptoms such as purple spots on the skin and subcutaneous mucous membranes, nosebleeds, bleeding gums, and coughing up blood. Many children give up or lose the opportunity to continue their education because of physical reasons, cannot engage in their favorite occupation, or simply Many children give up or lose the opportunity to continue their education, cannot pursue their favorite career, or are simply unable to perform the job of their choice. For female patients, this affects their marriage, and even if they are pregnant, their disease will affect the safety of the pregnant woman and her fetus.
