Rheumatic heart disease is a type of organic heart disease caused by an abnormal immune response, leading to pathological changes in the heart valves, which pose significant risks to the body. Due to valve insufficiency or stenosis, rheumatic heart disease causes changes in hemodynamics, leading to heart failure and pulmonary edema. These are severe conditions for patients and require timely treatment and correction. If effective dietary therapy is not administered, especially for pulmonary edema, it can be life-threatening.
