Изучение зависимости между выраженностью гипертрофии миокарда и изменением деформации, при которой обнаруживается нарушение систолической функции, у детей с гипертрофической кардиомиопатией (ГКМП) однозначно имеет важное значение.</p></sec><sec><title>Цель</title><p>Цель. Оценить взаимосвязь показателей гипертрофии и деформации миокарда левого желудочка у детей с ГКМП. Материалы и методы. Обследован 61 пациент с первичной формой ГКМП в возрасте от 7 до 17 лет. Проведено ультразвуковое исследование сердца по стандартной методике. Оценку деформации миокарда левого желудочка производили офлайн в режиме 2D-спекл-трекинг. Определяли сегментарную продольную, циркулярную и радиальную деформацию миокарда. Анализ гипертрофии сегментов миокарда проводился с учетом абсолютных значений толщины миокарда левого желудочка в систолу и диастолу в зависимости от возраста в перерасчете на единицы стандартного отклонения в популяции (Z-score factor).</p></sec><sec><title>Результаты</title><p>Результаты. При увеличении толщины миокарда левого желудочка более 2,48Z отмечалось снижение продольной деформации ниже релевантных значений, нарастание радиальной и отсутствие изменений циркулярной деформации. Дальнейшее снижение радиальной деформации наблюдалось при толщине миокарда более 4,24Z, циркулярной деформации – более 3,16Z. Взаимосвязь гипертрофии миокарда и продольной деформации имела обратную линейную зависимость: чем меньше показатели деформации, тем больше толщина миокарда. Радиальная деформация при увеличении толщины миокарда сначала имела тенденцию к компенсаторному нарастанию, затем, при увеличении толщины миокарда более 4,24Z, снижалась. Циркулярная деформация, также как и продольная, имеет обратную линейную зависимость, но с более длительным сохранением нормальных значений при нарастании гипертрофии миокарда.</p></sec><sec><title>Заключение</title><p>Заключение. У детей с ГКМП отмечаются различные виды взаимосвязи гипертрофии и деформации миокарда, определение которых является важным в оценке систолической функции левого желудочка для улучшения прогноза и тактики терапии заболевания. Комплексный подход к оценке деформации миокарда у детей с ГКМП должен включать не только общепринятое определение глобальной деформации, но и оценку сегментарной деформации для обнаружения ранних признаков нарушения функции миокарда. Важное диагностическое значение имеет сопоставление показателей различных видов деформаций и толщины миокарда левого желудочка для понимания степени изменения его кинетики.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. An assessment of the relationship between the severity of hypertrophy and changes in the myocardial strain at which systolic disfunction is detected in children with hypertrophic cardiomyopathy (HCM) is clearly essential.</p></sec><sec><title>Aim</title><p>Aim. To assess the relationship between hypertrophy and the myocardial strain in children with hypertrophic cardiomyopathy (HCM).</p></sec><sec><title>Materials and methods</title><p>Materials and methods. 61 patients aged between 7 and 17 years with a primary form of HCM underwent an ultrasound examination of the heart using standard techniques. An assessment of the left ventricular systolic function performed using of-line the two-dimensional (2D) speckle-tracking mode with analysis parameters that included global and segmental longitudinal, circumferential, and radial myocardial strains. The analysis of hypertrophy of myocardial segments carried out taking into account the absolute values of the thickness of the left ventricular myocardium in systole and diastole, depending on age, in terms of standard deviation units in the population (Z-score factor).</p></sec><sec><title>Results</title><p>Results. A decrease in longitudinal strain below the relevant values, an increase in radial strain, and no changes in circular strain were observed when the thickness of the left ventricular myocardium increased over 2.48Z. A further decrease in radial strain was observed when myocardial thickness was over 4.24Z, and circular strain was over 3.16Z. The relationship between myocardial hypertrophy and longitudinal strain had an inverse linear relationship: the lower the strain values, the greater the thickness of the myocardium. With increasing thickness of the myocardium, the radial strain first tended to increase in a compensatory manner, but it decreased when myocardial thickness increased over 4.24Z. The circular strain, as well as longitudinal one, has an inverse linear relationship, but with longer preservation of normal values when myocardial hypertrophy increases.</p></sec><sec><title>Conclusion</title><p>Conclusion. Children with HCM demonstrate various types of relationships between hypertrophy and myocardial strain, which detection is important for the assessment of the left ventricular systolic function to improve the prognosis and therapeutic approach to the disease. A comprehensive approach to the assessment of myocardial strain in children with HCM should include not only a routine identification of global strain, but also assessment of the segmental strain to detect early signs of myocardial dysfunction. Comparison of measures of various types of strain and the thickness of the left ventricular myocardium has a very important diagnostic value for understanding the degree of changes in its kinetics.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>гипертрофическая кардиомиопатия</kwd><kwd>эхокардиография</kwd><kwd>2D-спекл-трекинг</kwd><kwd>деформация миокарда</kwd><kwd>ранняя диагностика</kwd><kwd>лечение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>hypertrophic cardiomyopathy</kwd><kwd>echocardiography</kwd><kwd>2D speckle tracking</kwd><kwd>myocardial strain</kwd><kwd>early diagnosis</kwd><kwd>treatment</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">Леонтьева ИВ.
