Проведен анализ S и SR продольных, циркулярных и радиальных волокон в 450 сегментах ЛЖ до и после хирургической реваскуляризации у пациентов с ИБС без инфаркта миокарда.</p></sec><sec><title>Результаты</title><p>Результаты. Изучение средних показателей S и SR показало низкие значения S продольных волокон, снижение S и SR циркулярных волокон, нормальный показатель S и высокий SR радиальных волокон, а также отсутствие изменений деформационных свойств после реваскуляризации. Детальный анализ сегментов выявил снижение показателей S и SR у пациентов в ответ на ИБС в 211 (46,8%) продольных сегментах, в 232 (51,5%) циркулярных и в 116 (25,7%) радиальных волокнах ЛЖ. При этом 239 (53,2%) продольных сегментов, 218 (48,5%) циркулярных и 328 (72,8%) сегментов радиальных волокон имели нормальные и повышенные значения S и SR, а также разные варианты изменений S либо SR. После реваскуляризации деформационные свойства продольных и циркулярных волокон ЛЖ в группе с низкими значениями S и SR улучшились, а также увеличилось количество сегментов с высоким или нормальным значением SR. Нормальные значения S и SR радиальных волокон отмечаются в большинстве сегментов (254 (56,7%)). Все сегменты с изменением направления движения восстановили свою функцию, однако показатели деформации остались низкими.</p></sec><sec><title>Выводы</title><p>Выводы.

The study of averages S and SR showed the low S longitudinal fibers, low S and SR circular fibers and normal S and high SR radial fibers, no changes in these parameters after revascularization. A detailanalysis the segments showed a decrease S and SR in 211 (46.8%) segments of longitudinal, 232 (51.5%) circular and 116 (25.7%) of the radial fibers of the LV. The same 239 (53.2%) segments of longitudinal, 218 (48.5%) and circular 328 (72.8%) segments of the radial fibers had normal and increased values of S and SR as well as with different options to change S or SR. After revascularization improved deformation properties of longitudinal and circular fibers of the left ventricle in the group with low values of S and SR. The increased number of segments with high or normal value of SR. Normal values of S and SR radial fibers observed in most segments (254 (56.7%).</p></sec><sec><title>Conclusion</title><p>Conclusion.
