The purpose of present research is to estimate the influence of ischemic stroke on changes of clinical and instrumental parameters in patients with chronic heart failure (CHF) depending on expressiveness of neurologic deficiency. We supervised 103 patients with CHF, among them 71 patients with stroke. In all the patients twice heart rate variability and echocardiography were carried out. To determine CHF FC we used an estimation scale of a clinical condition (SHOCKS by Mareev, 2000). After 6 months all the patients were divided into 2 groups depending on expressiveness of neurological deficieny. Significant deterioration of heart rate variability (HRV) parameters in the group of patients with expressed neurological deficiency was revealed. Also in this group increase of end diastolic volume, end systolic volume and deterioration of diastolic function was revealed. 6 months after stroke in patients with CHF with expressed neurological deficiency reduction of parameters of HRV, progressiveness of hyperactivity of sympathetic adrenal system, deterioration of morphological-functional parameters of left ventrical was revealed.
