Морфофункциональное состояние головного мозга при хронической сердечной недостаточности

Abstract

The aim of the study was to examine the dependence of functional and morphological changes in the brain and factors of the severity of chronic heart failure. Materials and methods: 54 patients with chronic heart failure of ischemic genesis, I-IV functional class were cognitive tests, echocardiography, nuclear magnetic resonance imaging of the brain. Results. With an increase in the functional class of chronic heart failure, the worst results of Veksler-5 and 7 cognitive subtests are noted, a smaller thickness of gray matter of parietal lobes, lower diffusion coefficients of water molecules in the white matter of the parietal and occipital lobes, and a smaller thickness of the middle legs of the cerebellum. Comparative analysis of the central nervous system state indices in patients with chronic heart failure with different fraction of left ventricular ejection did not show significant differences. The conclusion. The established results confirm the significance of the functional class of chronic heart failure as a marker of cognitive dysfunction and pathological changes in both gray and white matter of the brain, whereas the size of the left ventricular ejection fraction is obviously less useful in this respect.
