If the patient has a history of mitral stenosis, it is still necessary to actively control the symptoms in treatment. Because mitral stenosis can cause hemoptysis, the amount of blood coughed up depends on individual factors. This condition can cause capillary rupture and bleeding, which may result in the coughing up of blood clots. This situation does not indicate whether there is a tumor, as mitral stenosis is a type of rheumatic heart disease or congenital heart disease. Currently, the treatment primarily focuses on symptomatic relief, actively controlling the heart rate, and managing changes in blood pressure and pulse, which can also improve this condition.
