Aortic regurgitation (insufficiency of aortic valve closure) refers to the backflow of blood from the aorta into the left ventricle through an insufficiently closed aortic valve. Doctors need to analyze the causes of aortic regurgitation in the context of medical history, clinical manifestations, etc. For example, congenital aortic valve lesions, rheumatic lesions, degenerative lesions, etc. The need for treatment of aortic valve lesions, including pharmacological and surgical treatment, is determined by a comprehensive analysis of the patient’s symptoms, the degree of regurgitation, left ventricular function, and the size of the left ventricle. For example, in asymptomatic patients with normal left ventricular function and mild or moderate aortic valve insufficiency, if the left ventricular end-diastolic diameter is less than 60-70 mm, the patient usually needs to be reviewed periodically to note the development of the disease and no treatment is needed for the time being. Most of the aortic regurgitation is caused by aortic insufficiency, and 2/3 of aortic insufficiency is caused by rheumatic heart disease. Therefore, it is vital to control the rheumatic activity in the acute stage, and prosthetic valve replacement or aortic valve repair is the most fundamental treatment measure, and medical treatment is generally only excessive measures for preoperative preparation. For chronic treatment: 1, prevention of infectious endocarditis, such as rheumatic activity in rheumatic heart disease should prevent rheumatic fever 2, syphilitic aortitis should be given a general course of penicillin treatment 3, diastolic blood pressure greater than 90mmhg application of antihypertensive drugs 4, asymptomatic light activity moderate regurgitation, should limit heavy physical labor, disease regular check echocardiography 5, angina pectoris available nitrate drugs 6, if there is Infections need to be controlled early and actively For prevention: prevent colds and cold, as soon as there is an upper respiratory tract infection needs to be treated immediately to avoid causing pneumonia to increase the burden on the heart. Most patients relapse clinically are caused by careless colds, so you need to strengthen exercise and enhance their resistance. Prevent the attack of wind, cold and dampness, do not crave cold in summer, avoid rheumatic activities, and increase nutrition appropriately. In fact, health care is very simple, as long as we develop good living and eating habits in our daily lives, to eliminate all harmful health behavior, it is easy to achieve the purpose of health care.
