The treatment of moderate pulmonary hypertension is mainly based on comprehensive treatment, which is chosen according to the different conditions of patients. The first is supportive therapy, including the use of anticoagulants, such as aspirin; diuretics, such as tachycardia, dihydroclonidine, etc.; digitalis, including digoxin, cediran, etc., to strengthen the heart, as well as appropriate oxygen intake. In addition, targeted drug therapy, including bosentan tablets, amlisentan tablets, iloprost, travoprost, etc., as well as interventional occlusion therapy, pulmonary vascular balloon dilatation and stent implantation, balloon atrial septostomy, etc., and other surgeries, including pulmonary artery thrombus endarterectomy. Lung transplantation can also be used to achieve a cure for moderate pulmonary hypertension that has repeatedly failed drug therapy.
