[Cardiac disorders and cognitive impairment in patients with chronic cerebral ischemia].

An objective of this paper was to study correlations between cardiac functions and cognitive disorders and to establish a prognostic role of the former in the progression of cerebrovascular pathology. We studied 102 patients, aged from 41-79 years, mean age 60,38±7,89 years. Standard instrumental methods for the study of the cardiovascular system and neuropsychological tests for the assessment of cognitive functions were used along with clinical neurological and somatic examination. It was shown that the age, level of diastolic pressure, atherosclerosis of brain vessels and valvular heart disease predicted cognitive impairment in patients with chronic brain ischemia. Reduced left ventricular ejection fraction was the main cardiac factor determining the severity of cognitive disturbances.
