[State of general and cerebral hemodynamics in patients with ischemic strokes].
In 64 patients with ischemic strokes that occurred on the background of atherosclerosis (33) and a combination of atherosclerosis with arterial hypertension (31) using the dilution method of Evans's blue the authors studied indices of general hemodynamics compared to rheoencephalographic data. Twenty similar patients without signs of brain circulation disturbances and 20 healthy persons were taken as control groups. In 69% of the patients with ischemic strokes deep disturbances of general hemodynamics were observed. An increase of tonus, a decrease of elasticity of cerebral vessels and deficit of pulse blood repletion were determined rheoencephalographically. Insufficiency of general hemodynamics in conditions of changed autoregulation of brain circulation promotes development of ischemic disorders of brain circulation and unfavourably influences the course and outcome of the stroke.
