[Pulmonary hypertension in chronic lung diseases]

The article provides data on the pathogenesis, hemodynamics and the contractile function of the myocardium in chronic diseases of the lungs aggravated with pulmonary hypertension. The data were based on complex clinical and instrumental examinations, including catheterization of the right segments of the heart with endomyocardial biopsy, rheography of the pulmonary artery, radiocardiography, radionuclide ventriculography. A three-stage stratification of pulmonary hypertension was proposed. The data are essential in assessments of occupational bronchial disorders, their prevention and treatment. A set of measures, both preventive and curative, was also proposed.
