[Left ventricular function in patients with chronic obstructive bronchitis].
A study of 45 patients with chronic obstructive bronchitis by the method of radionuclide ventriculography with 99mTc showed that even the early stages of the disease were characterized by an inhibition of the contractile function of the left cardiac ventricle. With progression of respiratory insufficiency, maintaining of the left cardiac ventricle stroke volume is achieved by increase of the final-diastolic and final-systolic volumes. Appearance of signs of cardiac decompensation is accompanied by a breakdown of this compensatory mechanism accompanied by a reduction of the strike volume and diminished rate of contraction of the circular fibers of the left ventricle myocardium.

[Central hemodynamic status and left ventricular contractile function in patients with chronic obstructive lung diseases and stable pulmonary hypertension (based on data from radionuclide study methods)].
Systemic, central and intracardiac hemodynamics and left-ventricular contractility were studied radiocardiographically and radioventriculographically in 22 patients with stable pulmonary hypertension, developing in the presence of chronic obstructive pulmonary diseases. A tendency to increased circulating blood volume, significantly elevated end diastolic and end systolic indices, reduced total ejection fraction, and a tendency to decreased segmental ejection fractions were demonstrated. A significant reduction of the speed and percentage of left-ventricular myocardial circular fibre contraction is another evidence of incompetent left-ventricular contractility, in addition to the reduced ejection fraction.
