Based on the mean pulmonary artery pressure level at rest, 38 mmHg is considered moderate pulmonary hypertension. It can be treated by initial treatment, supportive therapy and lung transplantation. 1. Initial treatment: give patients psychosocial support; recommend contraception if they are female patients of childbearing age; timely vaccination against influenza and Streptococcus pneumoniae; patients with reduced physical strength should be given the necessary rehabilitation on the basis of drug treatment. 2. Supportive therapy: mainly the individual or combined application of various drugs, including oral anticoagulant drugs, diuretics and vasodilator drugs. For patients with hypoxemia, oxygen therapy should be given to keep their arterial oxygen saturation greater than 90%. The patient should also be tested for anemia and iron status, and iron supplements should be given if there is a deficiency. 3. Lung transplantation: Lung transplantation can be performed in patients who do not respond well to aggressive medical treatment. Pulmonary arterial hypertension has many classifications, and there are many differences in treatment drugs and treatment modalities. It is recommended that patients with pulmonary arterial hypertension consult a respiratory physician in a timely manner, and under the guidance and advice of a specialized physician, choose a reasonable treatment plan according to the patient’s specific situation.
