Кардиоэмболический инсульт (КЭ) является одним из основным этиопатогенетических подтипов ишемического инсульта (ИИ) и составляет примерно 17% от всех пациентов с ИИ. В настоящее время ведется поиск широкодоступных методов лучевой диагностики, позволяющих с высокой точностью диагностировать дисфункцию левого предсердия (ЛП). К таким методам относят трансторакальную стрейн-эхокардиографию (ЭхоКГ), что дает дополнительное представление о мере деформации и изменении формы ЛП во время сердечного цикла. На сегодняшний день остается не изученной ассоциация между показателями стрейн-ЭхоКГ и выраженностью фибротических изменений ЛП у пациентов с ИИ.</p></sec><sec><title>Цель исследования</title><p>Цель исследования: оценить взаимосвязь между показателями деформации миокарда ЛП и степени выраженности его фиброза у пациентов с ИИ, а также влияние изменения деформации миокарда ЛП на прогноз пациентов с ИИ.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В проспективное поперечное исследование включено 132 пациента, проходивших обследование и лечение в отделении неотложной неврологии в ГБУЗ “НИИ скорой помощи имени Н.В. Склифосовского ДЗ города Москвы” в период с 2020 по 2022 г. В 1-ю группу включено 12 пациентов, умерших в ходе госпитализации, во 2-ю – 120 пациентов, выписанных из отделения после проведенного лечения.</p></sec><sec><title>Результаты</title><p>Результаты. Умершие пациенты по сравнению с выжившими характеризовались наличием ремоделирования миокарда ЛП. В исследуемых группах были выявлены статистически значимые различия в показателях деформации миокарда ЛП. При проведении корреляционного анализа были выявлены статистически значимые взаимосвязи между показателями деформации миокарда ЛП с выраженностью фиброзных изменений. В многофакторной модели логистической регрессии статистически значимое влияние на прогноз паципентов оказывали такие показатели, как деформация миокарда ЛП в фазу проводника и деформация миокарда ЛП в сократительную фазу, повышавшие шансы летального исхода при каждом последующем увеличении показателя на 1% в 1,128 и 1,075 раза соответственно (ОШ 1,128, 95% ДИ 1,021–1,25, p = 0,017 и ОШ 1,075, 95% ДИ 1,009–1,15, p = 0,025).</p></sec><sec><title>Выводы</title><p>Выводы. В ходе проведенного исследования было установлено, что показатель деформации миокарда ЛП сильно коррелирует с фиброзом ЛП и степенью фиброза ЛП. Показатели деформации миокарда ЛП могут быть использованы в стратификации риска развития летального исхода у пациентов с ИИ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Cardioembolic stroke (CE) is one of the main etiopathogenetic subtypes of ischemic stroke and accounts for approximately 17% of all patients with ischemic stroke. Currently, there is a search for widely accessible radiological diagnostic methods that allow for the accurate diagnosis of left atrial (LA) dysfunction. Among these methods is transthoracic strain echocardiography (EchoCG), which provides additional information about the degree of deformation and change in shape of the LA during the cardiac cycle. To date, the association between strain EchoCG parameters and the severity of fibrotic changes in the LA among patients with CE remains unstudied.</p></sec><sec><title>Objective</title><p>Objective. To evaluate the relationship between myocardial deformation parameters of the left atrium and the degree of fibrosis in patients with CE, as well as the impact of LA myocardial deformation changes on the prognosis of patients with CE.</p></sec><sec><title>Materials and Methods</title><p>Materials and Methods. A prospective cross-sectional study included 132 patients who underwent evaluation and treatment in the Department of Emergency Neurology at the N.V. Sklifosovsky Research Institute for Emergency Medicine from 2020 to 2022. Group 1 consisted of 12 patients who died during hospitalization, while Group 2 comprised 120 patients who were discharged from the department after receiving treatment.</p></sec><sec><title>Results</title><p>Results. Deceased patients, compared to survivors, were characterized by the presence of LA myocardial remodeling. Statistically significant differences in LA myocardial deformation parameters were found between the study groups. Correlation analysis revealed statistically significant associations between LA myocardial deformation parameters and the severity of fibrotic changes. In the multifactorial logistic regression model, significant effects on the prognosis of patients were observed for LA strain peak systolic circumferential strain rate (LA-Scs) and LA strain peak systolic longitudinal strain rate (LA-Sls), with each 1% increase in the parameter associated with a 1.128-fold and 1.075-fold increase in the odds of a lethal outcome, respectively (OR: 1.128, 95% CI: 1.021–1.25, p = 0.017, and OR: 1.075, 95% CI: 1.009–1.15, p = 0.025).</p></sec><sec><title>Conclusions</title><p>Conclusions. The conducted study established a strong correlation between LA myocardial deformation and LA fibrosis and the degree of fibrosis in the LA. LA myocardial deformation parameters can be used in risk stratification for the development of a lethal outcome in patients with CE. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ишемический инсульт</kwd><kwd>предсердная кардиомиопатия</kwd><kwd>спекл-трекинг-эхокардиография</kwd><kwd>фиброз миокарда</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ischemic stroke</kwd><kwd>atrial cardiomyopathy</kwd><kwd>speckle-tracking echocardiography</kwd><kwd>myocardial fibrosis</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">Воеводина И.В., Майчук Е.Ю., Иванова О.С.
