Pulmonary hypertension is an increase in pressure in the vessels of the pulmonary circulation in certain chronic lung diseases, heart defects, etc.
Varieties of pulmonary hypertension
- arterial (PAH),
- venous (LVG),
- pulmonary hypertension in combination with diseases of the respiratory system and / or with hypoxemia,
- pulmonary hypertension due to chronic thrombosis and / or thromboembolism of the pulmonary artery,
- pulmonary hypertension due to a direct violation of the pulmonary circulation.
This classification reflects a new understanding of pulmonary hypertension, highlighting the similarities and differences between primary pulmonary hypertension (PLH) of unknown etiology and secondary pulmonary hypertension (PLH) due to collagen diseases, congenital and acquired heart defects, portal hypertension, HIV infection, drug exposure.
The main symptoms of pulmonary hypertension
An echo-Doppler study can reveal that the average pressure in the pulmonary artery exceeds 25 mm Hg. Art. at rest or 30 mm Hg. Art. during exercise or systolic pressure greater than 40 mm Hg. Art.
Treatment of pulmonary hypertension
The underlying disease is being treated (elimination of pneumothorax, thrombolytic therapy or surgical intervention for pulmonary embolism, bronchial asthma therapy), as well as measures aimed at eliminating respiratory failure.
Prevention of pulmonary hypertension
Patients with chronic bronchopulmonary diseases are subject to dispensary observation in order to prevent exacerbation and conduct rational therapy for respiratory failure. Of great importance is the correct employment of patients with limited physical activity, which contributes to the increase in pulmonary hypertension.
