Исследование выполнено у 55 больных с IIIb типом ишемической митральной регургитации по A. Carpentier. Стандартная эхокардиография и методика “след пятна” (speckle tracking) для оценки деформации (strain) и скорости деформации (strain rate) папиллярных мышц были выполнены на ультразвуковой системе Vivid 7 Dimension (GE Healthcare, США). Оценены деформация, скорость деформации, время до максимальной деформации и максимальной скорости деформации в систолу передне-боковой и заднемедиальной папиллярных мышц. У 22,5% больных с ишемической митральной регургитацией II и III степени отсутствует деформация задне-медиальной папиллярной мышцы, у 13,0% пациентов с ишемической митральной регургитацией III степени - деформация передне-боковой папиллярной мышцы. Деформация задне-медиальной папиллярной мышцы взаимосвязана с показателями геометрии митрального клапана при III степени ишемической митральной регургитации (с диаметром фиброзного кольца митрального клапана (r = 0,44, P = 0,03), глубиной коаптации (r = 0,46, P = 0,02) и площадью тентинга створок митрального клапана (r = 0,74, P = 0,0002)). Деформация папиллярных мышц не зависит от нарушения локальной сократимости сегментов левого желудочка, прилежащих к папиллярным мышцам.</p></abstract><trans-abstract xml:lang="en"><p>Aim of the study was to assess the papillary muscles contractility in terms of strain and strain rate among patients with coronary artery disease according to the mitral regurgitation grading. Examination was done to 55 patients with IIIb type of ischemic mitral regurgitation according to A. Carpentier. Speckle tracking echocardiography was performed using Vivid 7 Dimension (GE Healthcare, USA) ultrasound system. Strain, strain rate, time to peak strain and strain rate of anterolateral and posteromedial papillary muscles in systole were assessed. There was no any strain of posteromedial papillary muscle in 22.5% of patients with II and III type of ischemic mitral regurgitation. There was no any strain of anterolateral papillary muscle in 13.0% of patients with III type of ischemic mitral regurgitation. There was a correlation between the posteromedial papillary muscle strain and mitral valve geometry in IIIb type of ischemic mitral regurgitation (mitral annular diameter (r = 0.44, P = 0.03), coaptation depth (r = 0.46, P = 0.02), and mitral valve tenting area (r = 0.74, P = 0.0002)). Papillary muscles strain did not depend on left ventricle local contractility disorders in segments, which are adjacent to the muscles.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эхокардиография</kwd><kwd>след пятна</kwd><kwd>деформация</kwd><kwd>скорость деформации</kwd><kwd>папиллярные мышцы</kwd><kwd>ишемическая митральная регургитация</kwd><kwd>геометрия митрального клапана</kwd><kwd>echocardiography</kwd><kwd>speckle tracking</kwd><kwd>strain</kwd><kwd>strain rate</kwd><kwd>papillary muscles</kwd><kwd>ischemic mitral regurgitation</kwd><kwd>mitral valve geometry</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">Бузиашвили Ю.И., Кокшенова И.В., Асымбекова Э.У., Тугеева Э.Ф., Голубев Е.П., Мацкеплишвили С.Т.
