The treatment principle of rheumatic heart disease in the asymptomatic stage is to maintain and enhance the compensatory function of the heart, and to choose internal medicine treatment. On the one hand, we should avoid overloading the heart, such as heavy physical labor and strenuous exercise, and on the other hand, we should pay attention to the combination of static and dynamic activities and exercises, so as to enhance physical fitness and improve the reserve capacity of the heart. Appropriate physical activity and rest, limiting sodium intake and the prevention and treatment of respiratory tract infections. Pay attention to the prevention of rheumatic fever and infective endocarditis. In case of combined heart failure, use digitalis preparations, diuretics and vasodilators. Treatment of rheumatic heart disease complications: 1. treatment of cardiac insufficiency; 2. rescue of acute pulmonary edema; acute pulmonary edema treatment is similar to pulmonary edema caused by acute left heart failure, with the difference that vasodilators and cardiac stimulants mainly for small arteries should not be used, and only when rapid atrial fibrillation occurs is it necessary to use cetiran to reduce ventricular rhythm. When the acute attack is accompanied by rapid ventricular rhythm, cediran is preferred to reduce the ventricular rhythm. 3.Control and eliminate atrial fibrillation. Surgical treatment of rheumatic heart disease for chronic rheumatic heart valve disease without symptoms, generally do not need surgery; symptomatic and belong to the indications for surgery, can choose to make artificial valve replacement or shaping, artificial valve replacement as the main method of treatment of adult aortic valve disease. 1, the indications for surgery: no obvious symptoms of cardiac function Ⅰ patients do not need surgical treatment. Patients with cardiac function II and III should undergo surgery. Patients with cardiac function grade IV should be treated with cardioplegia and diuretics, and then operated after the cardiac function is improved. Patients with atrial fibrillation, pulmonary hypertension, embolism of the body circulation and functional tricuspid valve insufficiency should also undergo surgery. However, the risk of surgery increases. Those with rheumatic activity or bacterial endocarditis should undergo surgery 6 months after rheumatic activity and endocarditis are completely controlled. 2, surgical methods: mainly two types of valve replacement and valvuloplasty. The decision should be made according to the valve lesion. There are also two types of valves, mechanical and biological. Doctors will generally recommend according to age, specific circumstances.
