Rheumatic heart disease is a type of organic heart disease, often caused by an abnormal immune response following a streptococcal infection, which affects the heart valves, resulting in valvular lesions, leading to stenosis or insufficiency, and posing significant risks to human health, severely impacting physical well-being. To prevent the occurrence of rheumatic heart disease, it is essential to actively control streptococcal infections, commonly including tonsillitis and upper respiratory tract infections. When a streptococcal infection occurs, effective antibiotics should be actively used to control the infection and reduce the incidence of rheumatic heart disease.
