Patients with pulmonary hypertension may present with exertional dyspnea, weakness, dizziness or syncope, chest pain, hemoptysis, and hoarseness. Patients with exertional dyspnea are mainly due to right heart failure, resulting in cardiac output not increasing with the increase of exercise, so there will be exercise dyspnea, which should be an early symptom of pulmonary hypertension, and patients with weakness should be related to the decrease of cardiac output and tissue hypoxia, and syncope is due to the decrease of cardiac output and the sudden decrease of blood supply to brain tissue, which is often seen after sudden standing up and exercise. The symptoms of chest pain are due to myocardial ischemia caused by increased right heart afterload, increased oxygen consumption and reduced coronary artery blood supply. Hemoptysis is caused by the rupture of capillaries in the lungs due to the increase of pulmonary artery pressure. Hoarseness is caused by the expansion of the pulmonary artery due to the increase of pulmonary artery pressure, which compresses the laryngeal nerve, so hoarseness occurs. Patients with pulmonary hypertension should promptly remove the causes of pulmonary hypertension, and symptomatic treatment is also crucial. Adequate rest, attention to temperature changes, prevention of secondary infections, etc.
