Оценить динамику когнитивного статуса в восстановительном периоде ишемического инсульта (ИИ) у пациентов с различным метаболическим статусом и выявить предикторы развития и прогрессирования когнитивных нарушений (КН) в группе больных с метаболическим синдромом (МС).Материал и методы. Обследовано 237 больных с диагнозом «Ишемический инсульт» на 21 -й день и через 12 месяцев после развития ИИ. Пациенты были разделены на 2 группы: 1-я группа — 115 больных с МС; 2-я группа — 122 пациента без МС. Для оценки КН применялась клиническая рейтинговая шкала деменции (КРШД). Проанализирована взаимосвязь (коэффициент корреляции (r), методы машинного обучения (прирост информации (п.и.)) показателя КРШД с демографическими, функциональными и лабораторными параметрами, характеристиками ИИ, наличием преморбидных КН (опросник IQCODE), индексом массы тела (ИМТ) и степенью комплаентности (шкала MMAS-8).Результаты. Через 12 месяцев после развития ИИ наблюдался более высокий процент пациентов с деменцией в 1-й группе (72,15%) в сравнении со 2-й группой (34,51%). Выявлена взаимосвязь показателя КРШД c уровнем ЛПНП (r = 0,397, п.и. = 0,346), IQCODE (r = 0,515, п.и. = 0,115), количеством метаболических факторов (r = 0,468, п.и. = 0,411), MMAS-8 (r = — 0,622, п.и. = 0,373), фенотипами МС: «гиперлипопротеинемия/гипергликемия/ожирение», «гиперлипопротеинемия/артериальная гипертензия/ожирение» и полнофакторного пересечения метаболических факторов в сочетании со степенью IQCODE, MMAS-8 (п.и. = 0,216, п.и. = 0,221, п.и. = 0,301).Заключение. Дисметаболические нарушения, как в отдельности, так и в контексте МС в комбинации с низкой комплаентностью, доинсультным когнитивным дефицитом и возрастным показателем способствуют значительному ухудшению КН в восстановительном периоде ИИ.</p></abstract><trans-abstract xml:lang="en"><p>Study purpose. To assess the dynamics of cognitive status during the recovery period following ischemic stroke (IS) in patients with different metabolic statuses and to identify predictors of the development and progression of cognitive impairment (CI) in a group of patients with metabolic syndrome (MS).Material and methods. 237 patients diagnosed with ischemic stroke on the 21st day and 12 months after the onset of IS were examined. The patients were divided into two groups: group 1 — 115 patients with MS; group 2 — 122 patients without MS. The Clinical Dementia Rating Scale (CDR) was used to assess CI. The relationship (correlation coefficient (r), machine learning methods (information gain, i.g.)) between the CDR score and demographic, functional and laboratory parameters, IS characteristics, the presence of premorbid CI (IQCODE questionnaire), body mass index (BMI) and degree of compliance (MMAS-8 scale) was analyzed.Results. Twelve months after the onset of IS, a higher percent of patients with dementia was identified in group 1 (72.15%) compared to group 2 (34.51%). A correlation was found between the CDR index and LDL level (r = 0.397, i.g. = 0.346), IQCODE (r = 0.515, i.g. = 0.115), the number of metabolic factors (r = 0.468, i.g. = 0.411), MMAS-8 (r = -0.622, i.g. = 0.373), MS phenotypes: ‘hyperlipoproteinemia / hyperglycemia / obesity’, ‘hyperlipoproteinemia / arterial hypertension / obesity’ and full-factor intersection of metabolic factors in combination with the degree of IQCODE, MMAS-8 (i.g. = 0.216, i.g. = 0.221, i.g. = 0.301).Conclusion. Dysmetabolic disorders, both individually and in the context of MS, combined with low compliance, prestroke cognitive impairment, and age, contribute to a significant deterioration in CI during the recovery period of IS.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>когнитивные нарушения</kwd><kwd>ишемический инсульт</kwd><kwd>метаболический синдром</kwd><kwd>клиническая рейтинговая шкала деменции</kwd><kwd>дисметаболические нарушения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cognitive impairment</kwd><kwd>ischemic stroke</kwd><kwd>metabolic syndrome</kwd><kwd>clinical dementia ranking scale</kwd><kwd>dysmetabolic disorders</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование было проведено в рамках Государственного задания FZWM-2024-0013.</funding-statement><funding-statement xml:lang="en">This work was performed within the scope of the State assignment FZWM-2024-0013.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Локшина АБ, Гришина ДА.
