Rheumatic heart disease is a type of organic heart disease caused by the body's abnormal reaction to infection with hemolytic streptococcus, leading to valve damage and the occurrence of rheumatic heart disease. It is directly related to upper respiratory tract infections and tonsillitis. To prevent the occurrence of heart disease, it is important to control infections early. Upon the appearance of upper respiratory tract infections, tonsillitis, or tonsillar suppuration, timely selection of effective antibiotics for treatment can control the infection early and prevent the onset of rheumatic heart disease.
