The survival time of patients with rheumatic heart disease is mainly related to the specific condition of the patient and cannot be generalized. Rheumatic heart disease is a cardiac lesion caused by rheumatic fever involving the heart valves, which can cause mitral, tricuspid, or aortic valve stenosis or incomplete closure. Severe rheumatic heart disease can manifest as symptoms of cardiac insufficiency such as panic, shortness of breath, weakness, cough, and swelling of the lower extremities. Depending on the severity of the condition, there is a wide variation in the life expectancy of patients. If a patient with rheumatic heart disease can be cured by valve replacement surgery, the patient’s life expectancy will not be affected; if the patient has severe rheumatic heart disease, which can no longer be treated surgically, its prognosis is poor and the patient’s life expectancy will generally not exceed 5 years. In addition, patients with rheumatic heart disease should be reviewed regularly at the hospital and given standardized medication to prevent thrombosis.
