[Changes in the cerebral circulation in persons with acquired heart defects]
Abstract:
A comprehensive estimation of the state of cerebral circulation was performed in 57 patients with acquired heart valve diseases (AHVD) of different types, etiology and severity. Doppler sonography, rheoencephalography and quantitative electroencephalography were used. It was determined that the alterations of cerebral circulation in patients with AHVD were first of all caused by disturbances of venous outflow due to congestive heart failure. Other factors, which had also influence on the results of the studies performed are outlined.
