Patients with rheumatic heart disease who experience heart failure must identify the causes of the heart failure, such as whether the patient has been overworked, excited, or has an infection. If such causes exist, they should be first eliminated, followed by treatments including diuresis, cardiac stimulation, and heart rate control. The most important thing is to address the complications caused by rheumatic heart disease, such as surgical treatment for mitral stenosis or mitral insufficiency, or relieving constrictive pericarditis caused by rheumatic pericarditis, all of which are methods to treat heart failure.
