[Peculiarities of the development of cerebral blood circulation disturbances in patients with chronic cardiac insufficiency].

One hundred and one patients with chronic cardiac insufficiency due to postinfarction cardiosclerosis have been examined. Clinical studies, echocardiography, duplex scanning of brachiocephal arteries were conducted. As the left ventricular (LV) is remodeled corresponding to a stage of chronic cardiac insufficiency (an increase of systolic and diastolic LV volumes, and myocardial mass, a decrease of ejection fraction), structural changes in the wall of extra- and intracranial vessels (the increase of intima-media complex and alteration of vessel geometry) increase and the cerebral dynamics (the decrease of systolic and volume velocities of blood flow) worsens.
