Оценка деформации миокарда левого желудочка и представления о релевантных значениях в детской популяции остаются недостаточно хорошо изученным вопросом.</p></sec><sec><title>Цель</title><p>Цель.Определить релевантные значения деформации и скорости деформации миокарда левого желудочка у детей и подростков.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Обследованы 67 здоровых детей и подростков в возрасте от 7 до 17 лет. 1-я группа – 30 детей от 7 до 11 лет; 2-я группа – 37 подростков от 12 до 17 лет. При эхокардиографии определялись показатели систолической функции левого желудочка: фракции выброса и укорочения, в режиме 2D-speckle-tracking – глобальные и  сегментарные продольная, циркулярная и радиальная деформации и скорости деформации миокарда.</p></sec><sec><title>Результаты</title><p>Результаты. У здоровых детей и подростков изучены релевантные значения глобальных  и сегментарных продольной, радиальной, циркулярной деформаций  миокарда левого желудочка и их скоростей. Выявлено статистически значимое  увеличение глобальной и сегментарной продольной деформации, скорости радиальной и циркулярной глобальной и сегментарной деформации во 2-й группе по сравнению с 1-й группой. Установлено, что наиболее однородное распределение значений в диапазонах доверительных интервалов отмечалось при оценке глобальной радиальной деформации и скорости циркулярной деформации миокарда, а также статистически значимое преобладание показателей деформации в субэндокардиальных слоях по сравнению с субэпикардиальными слоями миокарда.</p></sec><sec><title>Выводы</title><p>Выводы. 1. У подростков 12–17 лет по сравнению с детьми 7–11 лет отмечается  статистически значимое преобладание глобальной и сегментарной продольной  деформации, скорости радиальной и циркулярной глобальной и сегментарной  деформации миокарда левого желудочка. Радиальная деформация и скорость  циркулярной деформации миокарда левого желудочка являются наиболее однородными  в отличие от других показателей деформации. 2. У здоровых детей и подростков наблюдаются статистически значимые более высокие  показатели деформации в субэндокардиальном слое по сравнению с субэпикардиальным  слоем миокарда. 3. Полученные показатели глобальной и сегментарной деформации миокарда могут  служить в качестве нормативных для детей и подростков в оценке систолической функции левого желудочка.  </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction.To determine the relevant indicators of strain and strain rate of the left ventricular myocardium in children and adolescents.</p></sec><sec><title>Materials and methods</title><p>Materials and methods.

Had found that the uniform distribution of indicators in the ranges of confidence intervals, noted in the assessment of global radial strain and circular strain rate, as well as a statistically significant predominance of strain indicators in the subendocardial layers compared with the subepicardial layers of the myocardium left ventricle.</p></sec><sec><title>Conclusions</title><p>Conclusions. 1. In adolescents 12–17 years old, compared with children 7–11 years old, there is a statistically  significant predominance of global and segmental longitudinal strain, radial and circular strain rates of the left  ventricular myocardium. Radial strain and circular strain rate of the left ventricular myocardium are the most uniform in contrast to other indicators of strain.2. In healthy children and adolescents, had observed statistically significant higher strain and strain rate in the subendocardial layer compared to the subepicardial layer of the myocardium.3. The obtained indicators of global and segmental myocardial strain can serve as normative for children and  adolescents in assessing the systolic function of the left ventricle. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>эхокардиография</kwd><kwd>2D-speckle-tracking</kwd><kwd>миокард</kwd><kwd>деформация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>echocardiography</kwd><kwd>2D-speckle-tracking</kwd><kwd>miocardium</kwd><kwd>strain</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">Voigt J.U., Pedrizzetti G., Lysyansky P., Marwick T.H., Houle H., Baumann R. et al.
