Doctors who monitor patients with cardiovascular disorders do not have clearly set criteria for their referral to a neurologist in case of suspected CI. Therefore, CHF patients do not receive treatment for CI on time.</p> <p><bold>Aim</bold>: To identify significant clinical markers of CI in patients with CHF of ischemic origin.</p> <p><bold>Materials and methods</bold>: This cross-sectional cohort study included 134 patients with CHF of ischemic origin (mean age 63.36 ± 10.63 years; men, 76.12%), who were regularly monitored in a municipal polyclinic. All patients were tested for CI with the Montreal Cognitive Assessment Scale (MoCA); basic hemodynamic parameters, lipid profile, brain natriuretic peptide (NT-proBNP) were assessed, and triglyceride-glucose index (TyG) and body mass index (BMI) were calculated. Cardio-ankle vascular index (CAVI) was measured, echocardiography and a 6-minute walk test (SMWТ) were performed and past history of CHF, arterial hypertension (AH) and diabetes mellitus (DM) was collected.</p> <p><bold>Results</bold>: CI (MoCA score ≤ 25) was detected in 85 (63.43%) outpatients with CHF of ischemic origin; the group without CI (MoCA score &gt; 26) included 49 (36.67%) patients. There were significant correlations between MoCA and CAVI scores (partial correlation coefficient, r = -0.802, p &lt; 0.001; adjusted squared multiple correlation coefficient (adj. R<sup>2</sup>) = 0.881, p &lt; 0.001), MoCA and TyG (r = -0.357, p = 0.029; adj. R<sup>2</sup> = 0.363, p &lt; 0.001), MoCA and SMWТ (r = -0.211, p = 0.037; adj. R<sup>2</sup> = 0.696, p &lt; 0.001). The multivariate test for significance of planned comparisons between CAVI and MoCA scores (Wilks' lambda) was 0.005 (F = 4.74; p &lt; 0.001).</p> <p><bold>Conclusion</bold>: CAVI, TyG and SMWТ values are the clinical markers of CI in patients with CHF of ischemic origin. There is a direct association between increased CAVI and the presence of CI, regardless of age, lipid metabolism parameters, structural and functional heart parameters, CHF duration, AH and DM. Identification of these markers could be an indication for an in-depth assessment of CHF patients by a neurologist.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность</bold>. Когнитивные нарушения (КН) отмечаются у 25–50% больных хронической сердечной недостаточностью (ХСН). Врачи, наблюдающие больных по поводу сердечно-сосудистой патологии, не имеют четких критериев для направления к неврологу с подозрением на КН. Соответственно, пациенты с ХСН не получают своевременного лечения КН.</p> <p><bold>Цель</bold> – определить значимые клинические маркеры КН у больных с ХСН ишемического генеза.</p> <p><bold>Материал и методы</bold>. В рамках поперечного когортного исследования обследовано 134 пациента с ХСН ишемического генеза (средний возраст 63,36 ± 10,63 года; 76,12% мужчин), находившихся на диспансерном наблюдении в городской поликлинике. Всем пациентам проведено тестирование с использованием Монреальской шкалы оценки когнитивных функций (MoСА); определены основные гемодинамические параметры, липидный профиль, уровень мозгового натрийуретического пептида (NT-proBNP), рассчитаны триглицеридно-глюкозный индекс (TyG) и индекс массы тела (ИМТ); измерен сердечно-лодыжечный сосудистый индекс (СЛСИ), выполнены эхокардиография и тест с шестиминутной ходьбой (ТШМХ); по данным анамнеза определена продолжительность ХСН, артериальной гипертонии (АГ) и сахарного диабета (СД).</p> <p><bold>Результаты</bold>. У 85 (63,43%) амбулаторных больных ХСН ишемического генеза выявлены КН (≤ 25 баллов MoСА); группу без КН (&gt; 26 баллов MoСА) составили 49 (36,67%) пациентов. Статистически значимые корреляции установлены между баллами МоСА и СЛСИ (коэффициент частной корреляции (r) = -0,802, p &lt; 0,001; cкорректированный квадрат множественного коэффициента корреляции (adj. R<sup>2</sup>) = 0,881, p &lt; 0,001), МоСА и TyG (r = -0,357, p = 0,029; adj. R<sup>2</sup> = 0,363, p &lt; 0,001), МоСА и ТШМХ (r = -0,211, p = 0,037; R<sup>2</sup> = 0,696, p &lt; 0,001). Многомерный критерий значимости спланированных сравнений между СЛСИ и баллами МоСА (лямбда Уилкса) составил 0,005 (F = 4,74, р &lt; 0,001).</p> <p><bold>Заключение</bold>. Клиническими маркерами КН у больных с ХСН ишемического генеза были СЛСИ, TyG и ТШМХ. При этом установлена прямая связь повышенного СЛСИ с наличием КН независимо от возраста, показателей липидного обмена, структурно-функциональных показателей сердца, длительности ХСН, АГ и СД. Выявление этих маркеров может служить показанием для более тщательного обследования больных ХСН у невролога.</p></trans-abstract><kwd-group xml:lang="en"><kwd>heart failure</kwd><kwd>cognitive disorders</kwd><kwd>МоСА</kwd><kwd>arterial stiffness</kwd><kwd>cardio-ankle vascular index</kwd><kwd>walking test</kwd><kwd>echocardiography</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>сердечная недостаточность</kwd><kwd>когнитивные нарушения</kwd><kwd>МоСА</kwd><kwd>артериальная жесткость</kwd><kwd>сердечно-лодыжечный сосудистый индекс</kwd><kwd>тест ходьбы</kwd><kwd>эхокардиография</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Polyakov DS, Fomin IV, Belenkov YuN, Mareev VYu, Ageev FT, Artemjeva EG, Badin YuV, Bakulina EV, Vinogradova NG, Galyavich AS, Ionova TS, Kamalov GM, Kechedzhieva SG, Koziolova NA, Malenkova VYu, Malchikova SV, Mareev YuV, Smirnova EA, Tarlovskaya EI, Shcherbinina EV, Yakushin SS.
