    Abstract:
    Hemodynamics, external respiratory function (ERF), blood gas composition and viscosity were studied in 120 patients with chronic obstructive bronchitis at different developmental stage of cor pulmonale. In pulmonary hypertension, there were moderate ERF disorders that became more marked in the compensatory and particularly decompensatory cor pulmonale. As bronchial patency deteriorated, the index of right ventricular performance increased from 0.76+0.081 to 1.23+0.022 in the examinees. Examination of blood gas composition revealed insignificant hypoxemia in pulmonary hypertension and compensatory cor pulmonale, which progressed with decompensation of chronic cor pulmonale (CCP). As bronchial obstruction progressed, there were increases in systolic, diastolic, and mean pressure in the pulmonary artery. The viscosity of blood and plasma and the indices of red blood cell aggregation and deformability were in the normal range in pulmonary hypertension and compensatory CCP. In CCP decompensation, the viscosity of blood and plasma and the index of red blood cell aggregation were increased and the index of red blood cell deformability was decreased.
