The treatments for patients with mild pulmonary hypertension include general treatment and medication, while severe patients may also undergo surgery. 1. General treatment (1) Appropriate activity: it can reduce the symptoms, but the activity should not be too strong. (2) Prevention of infection: patients are prone to lung infections, which should be treated early. (3) Contraception: pregnancy can worsen the condition and should be contracepted. (4) Reduce blood viscosity: patients may have erythrocytosis, and bloodletting therapy can be used to reduce blood viscosity. (5) Anticoagulation therapy: patients are prone to pulmonary artery thrombosis and need anticoagulation therapy. (6) Oxygen therapy: low oxygen can aggravate the pressure of pulmonary circulation, oxygen therapy should be given. 2.Drug therapy (1) Calcium channel blockers: such as amlodipine, can dilate the pulmonary artery and reduce the pressure. (2) Prostacyclin drugs: such as beclomethasone, which can relax vascular smooth muscle and reduce pulmonary artery pressure. (3) Endothelin-1 receptor antagonist: such as bosentan, endothelin is a strong vasoconstrictor. (4) Phosphodiesterase inhibitor-5: It can inhibit the degradation of cyclic guanosine monophosphate, relax vascular smooth muscle cells, and reduce pulmonary artery pressure. (5) Nitric oxide and L-arginine: Nitric oxide is a vascular endothelial diastolic factor, and L-arginine is its precursor substance, which can promote nitric oxide synthesis. 3.Surgical treatment (1) Atrial septal balloon ostomy: may be beneficial in severe patients. (2) Lung transplantation or combined heart-lung transplantation: for advanced patients. Patients with pulmonary arterial hypertension should go to the hospital in time, and should not use medication on their own, but should standardize the treatment under the guidance of the doctor.
