Проверить гипотезу об изменениях белого вещества, вызванных церебральной гипоперфузией, у пациентов с фибрилляцией предсердий (ФП) и представить статистические вычисления для расчета размера выборки в будущих исследованиях.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В исследование были включены 30 пациентов с ФП, находящиеся на госпитализации, которым были проведены магнитно-резонансная томография (МРТ) со стандартными последовательностями и диффузионно-тензорная (ДТ) МРТ. Данные ДТ МРТ были проанализированы с помощью стандартного анализа области интереса (region of interest (ROI) analysis) в программном обеспечении Olea Sphere и с помощью наложения маски водоразделов в наборе инструментов FSL после нелинейного преобразования изображений в пространство Монреальского неврологического института (MNI space). Для сравнения характеристик диффузии в подгруппах использовался критерий Уилкоксона.</p></sec><sec><title>Результаты</title><p>Результаты. Средний возраст участников составлял 73 года (69-78), у 18 (60%) пациентов имелись умеренно выраженные признаки церебральной микроангиопатии (степень 1 по визуальной шкале Fazekas). У 21 пациента была установлена пароксизмальная форма ФП. Анализ данных показал снижение целостности белого вещества в теменнозатылочных зонах водоразделов со статистически значимым увеличением средней диффузии (p=0,039) и незначимым снижением фракционной анизотропии (p=0,056). Ранговая величина эффекта в сравниваемых областях была либо небольшой (0,2), либо незначимой, а статистическая мощность находилась в диапазоне 0,05–1.</p></sec><sec><title>Заключение</title><p>Заключение. Фибрилляция предсердий может иметь патофизиологически обоснованный механизм, влияющий на целостность белого вещества в зонах водоразделов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To test a hypothesis of hypoperfusion-induced white matter changes in patients with atrial fibrillation (AFib) and to present statistics to compute sample size for the upcoming studies.</p></sec><sec><title>Material and methods</title><p>Material and methods. We included 30 inpatients with AFib and investigated them with magnetic resonance imaging (MRI) with standard sequencies and diffusion tensor imaging (DTI). DTI data were analyzed with conventional ROI analysis in the Olea Sphere software and with watershed areas (WSA) mask in the FSL toolbox after nonlinear transformation of images to the Montreal Neurological Institute (MNI) space. Wilcoxon test was used to compare diffusion characteristics across subgroups.</p></sec><sec><title>Results</title><p>Results. Median age of participants was 73 years (69-78), 18 (60%) patients had moderate signs of small vessel disease with Fazekas score of one. Twenty-one patients had paroxysmal AFib. Analysis of WSA revealed decreased white matter integrity in the parieto-occipital cortical WSA with a pattern of significantly increased mean diffusivity (p=0,039), and marginally significant decrease in fractional anisotropy (p=0,056). Rank-based effect size across areas under comparison was either small (0,2) or negligible, and with statistical power in the range of 0,05-1.</p></sec><sec><title>Conclusion</title><p>Conclusion. Atrial fibrillation could have pathophysiologically feasible mechanism to affect white matter integrity in the watershed areas.</p></sec><sec><title> </title><p> </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>фибрилляция предсердий</kwd><kwd>водоразделы</kwd><kwd>церебральная микроангиопатия</kwd><kwd>диффузионно-тензорная визуализация</kwd><kwd>целостность белого вещества</kwd></kwd-group><kwd-group xml:lang="en"><kwd>atrial fibrillation</kwd><kwd>watershed areas</kwd><kwd>small vessel disease</kwd><kwd>diffusion tensor imaging</kwd><kwd>white matter integrity</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Настоящее исследование было выполнено в рамках исследовательского проекта РФФИ № 19-015-00383.
