[Characteristics of the pathogenesis of pulmonary hypertension and the formation of cor pulmonale in the basic forms of chronic nonspecific lung diseases].

A group of 206 patients with the main forms of chronic nonspecific diseases of the lungs (chronic bronchitis, chronic pneumonia, and bronchiectasis--local and diffuse) was studied. The condition of pulmonary ventilation, bronchial patency, and hemodynamics of pulmonary circulation were analysed. Comparison of the data obtained in different groups of patients made it possible to determine the main peculiarities of the pathogenesis of pulmonary hypertension and formation of cor pulmonale.
