At present, there is no cure data for pediatric dilated cardiomyopathy, but pediatric dilated cardiomyopathy can alleviate the symptoms and control the development of the disease through general treatment, drug treatment and surgical treatment. 1. General treatment: Diet should be nutritious and easy to digest and rich in high protein and high vitamin food, avoid spicy and stimulating food, ensure enough sleep, avoid strenuous exercise and excessive fatigue, and intermittent oxygen inhalation can improve the children’s oxygen supply which is conducive to the recovery of heart failure. 2. Drug therapy: When congestive heart failure occurs, cardiac drugs such as acetylated cardiac glycosides and diuretic drugs such as furosemide can be applied under the guidance of doctors. When arrhythmia occurs, individualized treatment can be carried out according to the type of arrhythmia; if atrial fibrillation occurs, drugs such as metoprolol can be used to treat it, and if ventricular arrhythmia occurs, lidocaine can be used to treat it. 3. Surgical treatment: Heart transplantation can be considered in cases of severe heart failure where medical treatment is ineffective. During the waiting period, if there are conditions, the left heart can be mechanically assisted to improve circulation. There is also a trial of left ventriculoplasty, through the removal of part of the enlarged left ventricle at the same time to replace the mitral valve, in order to reduce regurgitation, improve cardiac function, but the efficacy of the treatment is not yet certain. Should go to the hospital in a timely manner, by the doctor to diagnose the specific situation, targeted treatment with medication.
