Изучение динамики деформационных показателей волокон миокарда левого желудочка (ЛЖ) у пациентов с ишемической болезнью сердца (ИБС) после операции коронарного шунтирования (КШ) в ранние и отдаленные сроки.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. С помощью технологии Velocity Vector Imaging изучалась динамика деформации (S) и скорости деформации (SR) продольных, циркулярных и радиальных волокон у 148 пациентов (в 2646 сегментах ЛЖ) пациентов до и на 12-е сутки после КШ. В отдаленные сроки (6, 12 и 24 месяца) были обследованы 40 пациентов (720 сегментов ЛЖ).</p></sec><sec><title>Результаты</title><p>Результаты. На 12-е сутки после КШ отмечена положительная динамика SR продольных волокон (р=0,0002), отмечены слабые и средние корреляционные связи между S и SR радиальных (R=–0,56; R=–0,52) и циркулярных волокон с ЛДГ-1 и длительностью пережатия аорты. В отдаленные сроки у пациентов с жалобами отмечалось снижение глобальных деформационных свойств в бассейнах коронарных артерий. Стойкий результат улучшения S и SR продольных и циркулярных волокон, а также SR радиальных волокон получен в сегментах с исходно низкими деформационными свойствами.</p></sec><sec><title>Выводы</title><p>Выводы. Использование технологии Velocity Vector Imaging позволяет в ранние и отдаленные сроки оценить динамику деформационных показателей волокон ЛЖ. В ранние сроки после КШ отмечается положительная динамика только со стороны глобального SR продольных волокон. В отдаленные сроки отмечается снижение глобальных деформационных показателей продольных и циркулярных волокон в соответствии с бассейнами коронарных артерий. В отдаленные сроки отмечается значимое стабильное улучшение деформационных свойств сегментов с исходно низкими деформационными свойствами.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To study strain and strain rate dynamics the left ventricle (LV) myocardium fibers in patients with ischemic heart disease after coronary artery bypass grafting (CABG) in the early and late periods.</p></sec><sec><title>Material and methods</title><p>Material and methods. The dynamics of strain (S) and strain rate (SR) of longitudinal, circular and radial fibers in 148 patients (in 2646 LV segments) before and on the 12th day after CABG was studied using Velocity Vector Imaging technology. In the long-term (6, 12 and 24 months) 40 patients (720 LV segments) were examined.</p></sec><sec><title>Results</title><p>Results. A positive dynamics of SR longitudinal fibers (p = 0.0002) was on the 12th day after CABG. Weak and medium correlation was between S and SR radial (R = –0.56; R = –0.52) and circular fibers with LDG-1 and duration of aortic clamping. In the long term, patients with complaints showed a decrease in global deformation properties in the coronary artery areas. The stable result of improvement S and SR longitudinal and circular fibers and SR radial fibers was obtained in segments with initially low deformation properties.</p></sec><sec><title>Conclusions</title><p>Conclusions. The use of Velocity Vector Imaging technology allows to estimate the dynamics of LV fibers deformation parameters in early and long-term periods. In the early period after CABG was a positive dynamic only from the global SR longitudinal fibers. In the long-term global deformation parameters of longitudinal and circular fibers was decrease in in the area of the coronary arteries. In the long-term was a significant improvement of the deformation parameters of segments with initially low deformation properties.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Velocity Vector Imaging</kwd><kwd>деформация</kwd><kwd>скорость деформации</kwd><kwd>левый желудочек</kwd><kwd>коронарное шунтирование</kwd><kwd>ишемическая болезнь сердца</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Velocity Vector Imaging</kwd><kwd>strain</kwd><kwd>strain rate</kwd><kwd>left ventricle</kwd><kwd>coronary artery bypass grafting</kwd><kwd>CHD</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">Smiseth OA, Torp H, Opdahl A et al.
