[Intracardiac interrelations as a reflection of cardiac remodeling in obstructive pulmonary diseases]

Echocardiographic correlations between cardiac compartments were studied in 51 patients with obstructive ventilation disorders due to pulmonary diseases. All the compartments were closely related depending on the severity of the bronchial obstruction. In aggravation of the latter, integration of the atria, right atrium and left ventricle, right and left ventricles of the heart increases. The integration also grows between structural-functional indices of the left ventricle. At initial stages of bronchial obstruction functional and hemodynamic performance of the left ventricle depends more on its size, while later more on the wall thickness. It is demonstrated that obstructive disorders of ventilation promote closer integration of cardiac compartments, mobilization of compensatory hemodynamic reactions. The left ventricle plays an essential role in realization of staged compensatory reactions of the heart. Remodeling of the heart in obstructive pulmonary diseases is reflected in altered intracardiac relationships.
