Ишемический инсульт (ИИ) является одной из ведущих причин инвалидизации. Большинство случаев этого заболевания обусловлено модифицируемыми метаболическими факторами риска, ассоциированными с ожирением. Однако влияние состава тела на функциональный статус пациентов, перенесших ИИ, не определено.</p></sec><sec><title> Цель исследования</title><p> Цель исследования: оценка влияния мышечной и жировой ткани на функциональный статус и когнитивные нарушения у пациентов после ИИ.</p></sec><sec><title> Материал и методы</title><p> Материал и методы. Обследовано 65 пациентов, перенесших ИИ (возраст 62,9 ± 2,1 лет) — группа исследования и 43 добровольца — группа контроля (возраст 63 ± 5 лет). В зависимости от тяжести функциональных нарушений после инсульта по Модифицированной шкала Рэнкина (МШР) в группе исследования сформированы 2 подгруппы. В 1-ю подгруппу вошли 35 пациентов с отсутствием или легкими ограничениями жизнедеятельности, во 2-ю — 30 пациентов с выраженными ограничениями. Всем больным проведена оценка повседневной активности (индекс Бартел), когнитивное тестирование, оценены антропометрические данные и показатели биоимпедансометрии.</p></sec><sec><title> Результаты</title><p> Результаты. В сравнении с контрольной группой у пациентов после ИИ отмечено повышение параметров, отражающих состояние жировой ткани, а результаты оценки когнитивных функций и мышечной массы были ниже. У перенесших ИИ ожирение отмечалось в 46% случаев, снижение массы скелетной мускулатуры — в 93%. У пациентов с ожирением значения индекса Бартел были ниже, чем без такового (90 ± 7 vs 95 ± 6, p = 0.005). Индекс массы тела (ИМТ) и значения площади висцерального жира (ПВЖ) были выше при наличии нарушений жизнедеятельности (31,8 ± 1,5 vs. 28,4 ± 1.9 кг/см2; p = 0,003; 177 [158;192] vs. 141 [122;156] см2, p = 0,005). Определено пороговое значение ПВЖ (168,5 см2), превышение которого служит маркером выявления выраженных функциональных ограничений. Результаты оценки когнитивных функций у пациентов были ассоциированы со значением индекса скелетной мускулатуры (у мужчин r = 0,487, р = 0,001; у женщин r = 0,596, р = 0,007).</p></sec><sec><title>Заключение</title><p>Заключение. Висцеральное ожирение сопровождает более тяжелые постинсультные ограничения жизнедеятельности. Когнитивные нарушения у лиц, перенесших ИИ, ассоциированы с состоянием мышечной массы. ПВЖ выше 168.5 см2 может служить маркером более выраженных функциональных ограничений у больных, перенесших ИИ.</p></sec></abstract><trans-abstract xml:lang="en"><p>Ischemic stroke (IS) is one of the leading causes of disability. Most cases of this disease are caused by modifiable metabolic risk factors associated with obesity. However, the effect of body composition on the functional status of patients who have suffered an IS has not been determined.</p><sec><title> Purpose of the study</title><p> Purpose of the study. To assess the effect of muscle and adipose tissue on the functional status and cognitive impairment in patients after IS.</p></sec><sec><title> Material and methods</title><p> Material and methods. The study included 65 patients who had suffered an IS (age 62.9 ± 2.1 years) and 43 volunteers — the control group (age 63 ± 5 years). Depending on the severity of functional impairment after stroke (Modified Rankin Scale), the study group was divided into 2 subgroups. Subgroup 1 included 35 patients with no or mild limitations of life activities, and subgroup 2 included 30 patients with severe limitations. All patients underwent an assessment of daily activity (Barthel index), cognitive testing, anthropometric data and bioimpedancemetry parameters.</p></sec><sec><title> Results</title><p> Results. Compared with the control group, patients after IS showed an increase in parameters reflecting the state of adipose tissue, and the results of assessing cognitive functions and muscle mass were lower. In patients who had undergone IS, obesity was noted in 46% of cases, and a decrease in skeletal muscle mass was observed in 93%. In patients with obesity, the Barthel index values   were lower than in those without it (90 ± 7 vs 95 ± 6, p = 0.005). The body mass index (BMI) and visceral fat area (VFA) values were higher in the presence of disability (31.8 ± 1.5 vs. 28.4 ± 1.9 kg/cm2; p = 0.003; 177 [158;192] vs. 141 [122;156] cm2, p = 0.005). A threshold value of VFA (168.5 cm2) was determined, the excess of which serves as a marker for identifying severe functional limitations. The results of assessing cognitive functions in patients were associated with the value of the skeletal muscle index (men r = 0.487, p = 0.001; women r = 0.596, p = 0.007).</p></sec><sec><title> Conclusion</title><p> Conclusion. Visceral obesity accompanies more severe post-stroke limitations of life activities. Cognitive impairment in individuals who have suffered a stroke is associated with the state of muscle mass. An increase in the VFA from 168.5 cm2 can serve as a marker of major functional limitations in patients who have suffered a stroke.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ишемический инсульт</kwd><kwd>цереброваскулярные заболевания</kwd><kwd>цереброметаболическое  здоровье</kwd><kwd>ожирение</kwd><kwd>биоимпедансометрия</kwd><kwd>когнитивные нарушения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ischemic stroke</kwd><kwd>cerebrovascular diseases</kwd><kwd>cerebrometabolic health</kwd><kwd>obesity</kwd><kwd>bioelectrical impedance  analysis</kwd><kwd>cognitive impairment</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">GBD 2021 Stroke Risk Factor Collaborators.
