RESUMEN
Results of evaluation of cardiac rhythm variability (CRV) in Parkinson's disease (PD) are presented. High-resolution rhythmocardiography with a KAP-RK-01-Mikor diagnostic system was used to register CRY, peripheral and autonomous dysregulation of pacemaker activity of the synoatrial node. Reduced CRV was documented in 107 PD patients of whom 26% exhibited synoatrial dysfunction. The temporal statistical and spectral analysis of CRV, comparison of its results with clinical data suggest dissociation between cerebral and peripheral vegetative effects in PD, relatively well preserved suprasegmental ergotropic regulatory afferent impacts, and inadequate vegetative control at the post-ganglionic level.

Sensitive, emotional, intellectual, motivation, preoperative and postoperative aspects of the disease pattern were studied in 93 patients who had acquired valvular defects and underwent replacement of the valves in conditions of artificial circulation. The findings provided evidence in support of psychic correction for preoperative preparation of the patients and postoperative restoration of their personality and social status.

OBJECTIVE: To evaluate cognitive functions in patients with different stages of chronic heart failure (CHF) and different degrees of stenosis of precerebral arteries. MATERIAL AND METHODS: Authors examined 148 patients with CHF and 21 patients without CHF (controls). Neuropsychological assessment (NINDS-Canadian Stroke Standards - 30 minutes protocol), ultrasound scanning of the main cranial arteries and transcranial dopplerography and echocardiogram were made. RESULTS AND CONCLUSION: Patients with CHF more frequently had combined (multifocal) cognitive impairment. Patients with systolic heart failure performed significantly worse on neuropsychological tests, in particular, functional domains within the frontal lobes and "executive" dysfunction, than those with diastolic heart failure. Cognitive impairment in patients with CHF was associated with the lower left ventricular ejection fraction and deterioration in indices of diastolic function but not with carotid artery stenosis.
