Urgency. AH is a leading RF for development of hypertensive encephalopathy (HE) and CHF. Aim. To study peculiarities of cerebral hemodynamics in patients with HE and CHF. Material and methods. 113 patients with I–III stage HE with underlying degree 1–3 essential AH and 26 healthy subjects (control group) were evaluated. Results. As the HE stage progressed, a «congestive» type of carotid circulation with stable vertebral hemodynamics became notable. No dependence of blood flow parameters on HE stage was revealed. Most patients with HE had CHF; in a half of cases CHF was evident as asymptomatic LV diastolic dysfunction. Occurrence of CHF was associated with a subordination of vertebral blood flow to the heart systolic function and with development of more pronounced neurological disorders, in particular, the extrapyramidal or pseudobulbar syndrome. The management of patients with HE should make a provision for a possible remodeling of all target organs for AH, primarily the heart, a damage of which would inevitably result in impairment of central blood flow and progression of neurological disorders.
