Pulmonary hypertension refers to a hemodynamic and pathophysiological state in which pulmonary artery pressure is elevated above a certain threshold, which can lead to right heart failure and can be an independent disease, a complication, or a syndrome. Daily measures for the treatment of pulmonary hypertension 1. physical activity It is not clear whether physical activity can delay the development of pulmonary hypertension. However, the intensity of physical activity in patients should be such that no symptoms (such as dyspnea, syncope and chest pain) occur. Activities should be avoided after meals and in excessively high and low temperatures. Appropriate adjustment of daily activities can improve the quality of life and reduce the occurrence of symptoms. 2. Travel and altitude Low oxygen can aggravate pulmonary vasoconstriction in patients with pulmonary hypertension. Altitude of 1500m to 2000m is a mild low-pressure hypoxic area, therefore, patients should be advised to avoid such areas. The environment on commercial airplanes is similar to the state of 1500 meters to 2500 meters above sea level, and patients should be advised to take oxygen while riding. 3. Prevention of infection Patients with pulmonary hypertension are prone to lung infections and are poorly tolerated. Therefore, early diagnosis and active treatment should be provided. Influenza and pneumococcal vaccines are recommended. Patients with continuous administration of prostacyclin by intravenous catheter should be alerted to infection by the catheter route if they develop persistent fever. 4. Pregnancy, contraception, postmenopausal hormone replacement therapy Although successful pregnancy and delivery have been reported in patients with pulmonary hypertension, pregnancy and delivery usually worsen the patient’s condition and lead to death. Therefore, it is recommended that all women of childbearing age should use appropriate methods of contraception. If pregnancy occurs, it should be terminated promptly. There is no definitive conclusion as to which method of contraception is the best choice. If hormonal contraception is used, the effect on coagulation should be taken into account. It is unclear whether hormone replacement therapy should be used in menopausal women. Guidelines recommend using hormones only if symptoms are intolerable and considering the addition of anticoagulants. 5. Hemoglobin levels Patients with pulmonary hypertension tolerate reduced hemoglobin levels poorly, and even mild anemia should be managed promptly. On the other hand, patients with prolonged hypoxemia (e.g., presence of a right-to-left shunt) often develop erythrocytosis and an elevated erythrocyte ratio. When patients have headache, poor concentration and other symptoms, accompanied by an erythrocyte ratio of more than 65%, bloodletting therapy can be considered to reduce blood viscosity and increase the ability of blood to release oxygen to tissues. 6.Psychotherapy Patients with pulmonary hypertension have an early age of onset (median age is 40 years) and disrupt their previous lifestyle due to limited physical activity. Moreover, they are often influenced by incorrect information about the disease from non-professionals, so many patients have varying degrees of anxiety and/or depression. Therefore, the patient should be provided with adequate information and active treatment in cooperation with the family. If necessary, patients are advised to receive treatment from a psychiatrist.
