Abstract

Obtained data of changes in parameters of pulmonary hemodynamics, geometry, left and right heart function in patients with chronic obstructive pulmonary disease showed the progressive increase of pulmonary hypertension. We noted parallel increase of pulmonary hypertension and hypertrophy, dilatation of right ventricle, dilatation of right and left atrium, hypertrophy of left ventricle. We revealed the influence of initial expressiveness for bronchial obstructive syndrome, respiratory insufficiency, hypoxemia on the level of systolic pulmonary pressure, expressiveness of right ventricle hypertrophy and dilatation, right ventricular diastolic function through 12 and 24 months. During the first year of observation we noted parallel comparable increase of pulmonary hypertension, right ventricle hypertrophy and dilatation. But if during the next year of observation the rates of pulmonary hypertension and right ventricle hypertrophy reduce, dilatation of right ventricle continues. During a 2-year observation we noticed progressive remodelling of the left heart: increase of end-diastolic size in left atrium and ventricle, increase of thickness of left ventricle posterior wall and interventricular septum, left ventricle myocardial mass index.
