Материал и методы: обследовано 145 больных, разделенных на три группы: 1-ю группу составили 30 пациентов с НС (30), 2-ю группу - 62 пациента с передними ИМ, 3-ю группу - 53 пациента с нижними ИМ. Всем пациентам проведена трансторакальная эхокардиография на сканере Affiniti 70 (Philips, Нидерланды) с использованием пакета программ аСМQ. Оценивались максимальные систолические пики сегментарной и глобальной продольной и циркулярной деформации, систолической и диастолической ротации, скручивание и раскручивание ЛЖ. По кривым базальной и апикальной ротации ЛЖ регистрировались волны базальной и апикальной ПР. Результаты: преимущественное влияние на скручивание и раскручивание ЛЖ оказывает величина циркулярной деформации апикальных сегментов ЛЖ. Положительная волна базальной ПР выявлялась чаще (44,1%), чем отрицательная волна апикальной ПР (31,7%) (Р &lt; 0,05). Наличие ПР базальных сегментов ЛЖ ассо циируется с большими значениями базаль ной систолической ротации (-3,0 ± 2,0 °, -8,4-1,2 °) (здесь и далее: M ± SD, мини мальное - максимальное значения) и меньшими значениями величины скручивания ЛЖ (7,5 ± 3,5 °, -1,0-16,4 °), чем при отсутствии волны ПР (-4,5 ± 1,9 °, -12,1-0,1 °, P &lt; 0,0001 и 9,1 ± 4,1 °, 0,5- 21,5 °, P &lt; 0,05 соответственно). При наличии базальной ПР среди всех исследованных пациентов величина GLS достоверно ниже, чем при отсутствии волны ПР (-12,1 ± 3,4%, -18,2--3,0% и -10,7 ± 3,5%, -17,2--2,8% соответственно, P &lt; 0,05). Соотношение GCS/GLS при наличии ПР достоверно снижается (при отсутствии ПР - 1,92 ± 0,59, 0,96-4,10, при наличии - 1,71 ± 0,46, 0,67-3,70, P &lt; 0,05). При НС и ИМ снижение величины систолической циркулярной деформации базальных сегментов &lt;20% (модуль) при наличии волны базальной ПР сочетается со снижением индекса скручивания &lt;1,0 °/см (P &lt; 0,05). При НС и ИМ снижение величины систолической циркулярной деформации базальных сегментов &lt;20% (модуль) при наличии волны базальной ПР сочетается со снижением индекса раскручивания &lt;0,35 °/см (P &lt; 0,05). Выводы: волна базальной ПР ЛЖ встречается чаще при нижних ИМ по сравнению с передними ИМ (Р &lt; 0,05). Наличие волны базальной ПР ЛЖ у больных с НС и ИМ ассоциируется с меньшими значениями скручивания ЛЖ (P &lt; 0,05). Наличие базальной ПР при НС и ИМ выступает фактором, модулирующим влияние циркулярного сокращения базального сегмента ЛЖ как на величину индекса скручивания, так и на величину индекса раскручивания.</p></abstract><trans-abstract xml:lang="en"><p>Objective: to evaluate the role of initial systolic rotation (ISR) of left ventricle (LV) in twist and untwist modulation in unstable angina (UA) and myocardial infarction (MI). Material and methods: 145 patients were examined and divided into three groups, the first of which included 30 patients with UA, the second - 62 patients with anterior MI, the third - 53 patients with inferior MI. Transthoracic echocardiography was performed in all patients with the use of Affiniti 70 (Philips, Netherlands) with aCMQ (automatic cardiac movement quantitative analysis) software. The maximal systolic peaks of segmental longitudinal and circular strain and global longitudinal and circular strain (GLS and GCS), systolic and diastolic rotation, twist and untwist of the left ventricle were assessed. The evaluation of basal and apical ISR based on curves of basal and apical LV rotation. Results: the twist and untwist of LV is predominantly influenced by the magnitude of circular strain of LV apical segments. A positive wave of basal ISR was obtained with higher frequency (44.1%) than a negative wave (31.7%) (P &lt; 0.05). The presence of ISR of left ventricle basal segments is associated with greater basal systolic rotation and lesser LV twist (hereinafter: M ± SD, minimal - maximal values) (-3.0 ± 2.0 °, -8.4-1.2 ° and 7.5 ± 3.5 °, -1.0-16.4 °, respectively) than in the absence of the ISR wave (-4.5 ± 1.9 °, -12.1-0.1 °, P &lt; 0.0001 and 9.1 ± 4.1 °, 0.5-21.5 °, P &lt; 0.05, respectively). In all patients GLS values were significantly lower in the presence of basal ISR than in absence of it (-12.1 ± 3.4%, -18.2--3.0% and -10.7 ± 3,5%, -17.2--2.8%, respectively, P &lt; 0.05). Significant GCS/GLS ratio decrease was obtained in the presence of ISR in comparison with its absence (1.71 ± 0.46, 0.67-3.70 and 1.92 ± 0.59, 0.96-4.10, respectively, P &lt; 0.05). In UA and MI, a decrease in the systolic circular strain magnitude of basal segments &lt;20% (modulus) in the presence of a basal ISR wave is combined with a decrease of the twisting index &lt;1.0 °/cm (P &lt; 0.05). In UA and MI, a decrease in the systolic circular strain magnitude of basal segments &lt;20% (modulus) in the presence of a basal ISR wave is combined with a decrease in the untwisting index &lt;0.35 °/cm (P &lt; 0.05). Conclusions: the occurrence of basal ISR wave is higher in inferior MI than in anterior MI (P &lt; 0.05). The presence of basal ISR wave is associated with lower values of LV twist in patients with UA and MI (P &lt; 0.05), and modulate the effect of LV basal segment circular contraction on the value of the twisting and untwisting indices.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>спекл-трекинг эхокардиография</kwd><kwd>деформация миокарда</kwd><kwd>предварительная ротация</kwd><kwd>скручивание</kwd><kwd>раскручивание</kwd><kwd>левый желудочек</kwd><kwd>ишемическая болезнь сердца</kwd></kwd-group><kwd-group xml:lang="en"><kwd>speckle tracking echocardiography</kwd><kwd>myocardial strain</kwd><kwd>initial systolic rotation</kwd><kwd>twist</kwd><kwd>untwist</kwd><kwd>left ventricle</kwd><kwd>coronary heart disease</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">Ibanez B., James S., Agewall S., Antunes M.J., Bucciarelli-Ducci C., Bueno H., Caforio A.L.P., Crea F., Goudevenos J.A., Halvorsen S., Hindricks G., Kastrati A., Lenzen M.J., Prescott E., Roffi M., Valgimigli M., Varenhorst C., Vranckx P., Widimsky P.; ESC Scientific Document Group. 2017 ESC Guidelines for the management of acute myocardial infarction in patients presenting with ST-segment elevation: The Task Force for the management of acute myocardial infarction in patients presenting with ST-segment elevation of the European Society of Cardiology (ESC).
