В исследование были включены 155 детей, из них 108 детей возрасте от 1 года до 5 лет, рожденных с очень низкой массой тела (ОНМТ) и экстремально низкой массой тела (ЭНМТ), и 47 здоровых детей того же возраста, рожденных доношенными. Дизайн выполненного исследования: пилотное, одномоментное, ретроспективное, «случай – контроль» исследование. Эхокардиография (ЭхоКГ) выполнена на ультразвуковой системе Vivid Е9 (GE, Healthcare) с использованием матричного датчика M5S (1,5–4,6 MHz). Проведена оценка глобальной циркумференциальной (GCS MV, GCSPM, GCSApex) и продольной деформации ЛЖ, глобальной деформации эндокардиального, среднего и эпикардиального слоев ЛЖ.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Четвертый («реверсивный») тип скручивания ЛЖ (движение апикальных отделов ЛЖ в систолу «по часовой стрелке») обнаружен у 33,33% детей, имевших в анамнезе признаки бронхолегочной дисплазии (БЛД), и у 28,13% детей, получавших искусственную вентиляцию легких (ИВЛ) в неонатальный период. У 25 (69,44%) из 36 детей с признаками анемии в неонатальный период отмечено снижение деформации по окружности эпикардиального слоя ЛЖ. В 13 (86,67%) из 15 клинических наблюдений с признаками транзиторного гипотиреоза в анамнезе также выявлено снижение деформации по окружности эпикардиального слоя.</p></sec><sec><title>Заключение</title><p>Заключение. Факторы «масса тела при рождении», «задержка внутриутробного развития (ЗВУР) плода», «анемия, применение ИВЛ в неонатальный период», «транзиторный гипотиреоз», «развитие БЛД» у детей раннего и дошкольного возрастов, рожденных недоношенными с ОНМТ и ЭНМТ, неблагоприятно влияют на становление контрактильности и вращательной механики ЛЖ в постнатальный период, усугубляя нарушения, вызванные незрелостью ткани детского сердца и реализацией иных патогенетических механизмов при недоношенности, что требует врачебного наблюдения за данной клинической группой в амбулаторных условиях.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim: To study contractility of the left ventricle (LV) in prematurely born children of early and preschool age who received treatment in intensive care units, neonatal intensive care units and pathology of newborns in the neonatal period.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. The study included 155 children, of which 108 children aged from one to five years old, born with very low body weight and extremely low body weight; and 47 children of the same age, born full-term and healthy. Study design: pilot, cross-sectional, retrospective, case-control study. EchoCG was performed using the Vivid E9 ultrasound system (GE, Healthcare) with M5S matrix probe (1.5–4.6 MHz). The LV global circumferential (GCSMV, GCSPM, GCSApex), and longitudinal strain, as well as the global strain of the endocardial, middle and epicardial layers of the LV were assessed. in the systole “clockwise”) was found in 33.33% of children with a history of bronchopulmonary dysplasia, and in 28.13% of children who received mechanical ventilation during the neonatal period. In 25 (69.44%) of 36 children with signs of anemia in the neonatal period, there was a decrease in deformation along the circumference of the LV epicardial layer. In 13 (86.67%) of 15 clinical observations with signs of transient hypothyroidism in the anamnesis, a decrease in deformation along the circumference of the epicardial layer was revealed.</p></sec><sec><title>Conclusion</title><p>Conclusion. Factors “body weight at birth”, “fetal growth retardation”, “anemia, use of mechanical ventilation in the neonatal period”, “transient hypothyroidism”, “development of bronchopulmonary dysplasia” in children of early and preschool age born prematurely with very low and extremely low body weight, adversely affect the formation of LV contractility and rotational mechanics in the postnatal period, exacerbating the disorders caused by the immaturity of the child’s heart tissue and the implementation of other pathogenetic mechanisms in prematurity, which requires medical supervision of this clinical group in polyclinic conditions.  </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>недоношенность</kwd><kwd>детское сердце</kwd><kwd>механика левого желудочка</kwd><kwd>задержка внутриутробного развития</kwd><kwd>искусственная вентиляция легких</kwd><kwd>анемия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>prematurity</kwd><kwd>children’s heart</kwd><kwd>left ventricular mechanics</kwd><kwd>intrauterine growth restriction</kwd><kwd>mechanical ventilation</kwd><kwd>anemia</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>представленная публикация выполнена в соответствии с планом НИИ кардиологии Томского НИМЦ по фундаментальной теме «Фундаментальные аспекты формирования структурно-функциональных изменений сердца и сосудов в разных возрастных группах на доклинической, клинической стадиях и после гемодинамической коррекции сердечно-сосудистых заболеваний».
