To study in healthy individuals the gender and age characteristics of left ventricular (LV) myocardial work indicators, their correlations with global LV deformity indicators and echocardiographic parameters characterizing LV systolic and diastolic functions.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. 70 Healthy individuals (n=70; 34 men and 36 women; aged 39.3±8.9 years) were included in the study. The echocardiographic examination determined the standard parameters and indicators of myocardial work: global work efficiency (GWE), global constructive work (GCW), global wasted work (GWW), global myocardial work index (GWI); as well as the myocardium deformation characteristics: global longitudinal deformation (GLS), global radial deformation (GRS) and global circular deformation (GCS). Spearman's correlation coefficient was used to investigate the relationship between parameters. A correlation was considered weak at r≤0.3, moderate at 0.3&lt;r&lt;0.7, and strong at r≥0.7.</p></sec><sec><title>Results</title><p>Results. The average value of global work efficiency (GWE) in men was 97% (96; 98), in women – 98% (97; 98). Global constructive work (GCW) in men was 2343.8±350.4 mm Hg%, in women – 2362.2±343.8 mm Hg%. The average value of global wasted work (GWW) in men was 46 mm Hg% (27; 75), in women – 44 mm Hg% (33; 55.5). The global myocardial work index (GWI) in men was 2069.9±356.4 mm Hg%, in women – 2055.7±339.9 mm Hg%. No significant differences were found in the comparative analysis of performance indicators. The analysis of correlations found that the myocardial work indicators didn't have significant correlations with age. Ejection fraction was moderately correlated with GWI (r=0.45) and GCW (r=0.49). Global longitudinal strain was strongly correlated with GWI (r=0.77) and GCW (r=0.77). Global radial strain correlated moderately directly with GWI (r=0.4) and GCW (r=0.4). Global circular strain was moderately correlated with GCW (r=0.35). A strong negative correlation was found between the GWE indicator and the post systolic contraction index (PSI) (r=-0.85). At the same time, PSI and GWW had a strong positive correlation (r=0.85).</p></sec><sec><title>Conclusion</title><p>Conclusion. Indicators of LV myocardial work in healthy individuals do not have gender differences. The efficiency of the work of the myocardium depends primarily on the deformation of the LV, while the constructive work is determined by the volume characteristics. The wasted work indicator depends on the number of segments that peak in the post-systolic period.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цель</title><p>Цель. Изучить у здоровых лиц гендерные особенности показателей миокардиальной работы левого желудочка (ЛЖ), их корреляцию с глобальными деформационными показателями ЛЖ и эхокардиографическими параметрами, характеризующими систолическую и диастолическую функции ЛЖ.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование включено 70 здоровых лиц в возрасте 39,3±8,9 лет (34 мужчины и 36 женщин). При эхокардиографическом исследовании определяли стандартные параметры, показатели миокардиальной работы: глобальную эффективность работы (GWE), глобальную конструктивную работу (GCW), глобальную работу вхолостую (GWW), индекс глобальной работы миокарда (GWI), а также деформационные характеристики миокарда: глобальную продольную деформацию (GLS), глобальную радиальную деформацию (GRS), глобальную циркулярную деформацию (GCS). Для исследования взаимосвязи между параметрами применяли коэффициент корреляции Спирмена. При r≤0,3 корреляцию считали слабой, умеренной – при 0,3&lt;r&lt;0,7 и сильной – при r≥0,7.</p></sec><sec><title>Результаты</title><p>Результаты. Среднее значение глобальной эффективности работы (GWE) у мужчин составило 97% (96; 98), у женщин – 98% (97; 98). Глобальная конструктивная работа (GCW) у мужчин составила 2343,8±350,4 мм рт.ст.%, у женщин – 2362,2±343,8 мм рт.ст.%. Среднее значение глобальной работы вхолостую (GWW) у мужчин составило 46 мм рт.ст.% (27; 75), у женщин – 44 мм рт.ст.% (33; 55,5). Индекс глобальной работы миокарда (GWI) у мужчин составил 2069,9±356,4 мм рт.ст.%, у женщин – 2055,7±339,9 мм рт.ст.%. Значимых различий при сравнительном анализе показателей получено не было. Установлено, что показатели миокардиальной работы не имели значимых корреляций с возрастом. Фракция выброса умеренно коррелировала с GWI (r=0,45) и GCW (r=0,49). Глобальная продольная деформация имела сильную корреляцию с GWI (r=0,77) и GCW (r=0,77). Глобальная радиальная деформация умеренно прямо коррелировала с GWI (r=0,4) и GCW (r=0,4). Глобальная циркулярная деформация имела умеренную корреляцию с GCW (r=0,35). Сильная отрицательная корреляция была выявлена между показателем GWE и индексом постсистолического сокращения (PSI) (r=-0,85). При этом PSI и GWW имели сильную положительную корреляцию (r=0,85).</p></sec><sec><title>Заключение</title><p>Заключение. Показатели миокардиальной работы ЛЖ у здоровых лиц не имеют гендерных различий. Эффективность работы миокарда в первую очередь зависит от деформации ЛЖ, тогда как конструктивная работа определяется объемными характеристиками. Показатель работы вхолостую зависит от количества сегментов, пик сокращения которых приходится на постсистолический период.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>глобальная миокардиальная работа</kwd><kwd>спекл-трекинг эхокардиография</kwd><kwd>постсистолическое сокращение</kwd><kwd>кривая давлениедеформация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>global myocardial work</kwd><kwd>speckle tracking echocardiography</kwd><kwd>postsystolic contraction</kwd><kwd>pressure-strain loop</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена при финансовой поддержке российского фонда фундаментальных исследований в рамках научных проектов №№ 20-315-90025, 19-315-90031</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The research was carried out with the financial support of the Russian Foundation for Basic Research within the framework of scientific projects No. 20-315-90025, 19-315-90031</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Lang RM, Badano LP, Mor Avi V, et al.
