Abstract. Вackground. Chronic heart failure (CHF) has a high prevalence in the Russian population. It is one of the main causes of reduced quality of life in cardiology patients due to the gradual progression of the disease and the development of complications, as well as the development of cognitive impairment. Early recognition of these disorders will optimize the management of patients with CHF. Purpose of the study. To evaluate the quality of life and cognitive functions in patients with different severity of chronic heart failure. Characterization of patients and methods of the study. 105 patients with confirmed diagnosis of CHF with different functional classes according to NYHA were included in the open cross-sectional non-randomized cohort study. Cognitive screening was performed using the Montreal Cognitive Assessment (MoCA), and quality of life was assessed by the Quality of Life Questionnaire (EQ-5D). Statistical Analysis Methods. Excel data analysis package and SPSS 23.0 data analysis package were used. Results and Conclusion. A pilot study was conducted to detect mild or severe cognitive impairment using the Montreal Cognitive Scale and quality of life using the EQ-5D questionnaire in patients with different functional classes of CHF. A significant correlation was found between cognitive function and left ventricular ejection fraction. Quality of life did not depend on the severity of CHF, sex, age, concomitant pathology. The obtained data should be taken into account in personalized management of patients with CHF.
