Patients with rheumatic heart disease should go to the hospital for assessment, undergo cardiac ultrasound, and perform exercise tests. If the exercise test indicates cardiac function is below class II, or if the six-minute walk test reaches above class IV, exercise can be pursued. If patients have concerns, they can exercise under the guidance of a cardiac rehabilitation therapist at the hospital. For patients with cardiac function class III and above, exercise is not recommended. It is advised that they manage heart failure in the hospital or consider exercise only after surgery and when the condition is stable.
