Rheumatic heart disease cannot heal itself, because it is caused by pathological damage to the heart valves, leading to narrowing of the valves and incomplete closure. Through careful treatment and management, clinical symptoms can be alleviated, but it cannot heal itself. Those with rheumatic heart disease must take it seriously, try to reduce the burden on the kidneys, and minimize colds. Eating easily digestible food, reducing the burden on the heart, and adhering to a low-salt, low-fat diet are recommended.
