В проспективное исследование включено 79 пациентов с СНнФВ ЛЖ с клиническими проявлениями хронической сердечной недостаточности функционального класса III по Нью-Йоркской кардиологической ассоциации (СН ФК III по NYHA) у 52 больных (65,8%) и ФК IV по NYHA у 27 (34,1%). Первичной конечной точкой выбраны летальный исход в сроки наблюдения до 3 лет в период ожидания трансплантации сердца.</p></sec><sec><title>Результаты</title><p>Результаты. Общая смертность составила 33 (41,7%)пациента, в течение 1-го года наблюдения – 17 (21,5%) больных. По результатам регрессионного анализа ультразвуковыми независимыми предикторами неблагоприятного прогноза стали фракция выброса ЛЖ при трехмерной эхокардиографии (3DE ФВЛЖ), p = 0,014; глобальная продольная деформация ЛЖ (GLS LV), p = 0,010 и базального сегмента межжелудочковой перегородки (IVSLS BS), p = 0,012; средняя продольная деформация базального сегмента свободной стенки правого желудочка (ПЖ) (FWLS BS RV), p = 0,003. Изменения конфигурации и дилатация полости ЛЖ, увеличение конечного диастолического давления ЛЖ, нарушение сократимости и деформационных свойств миокарда ЛЖ могут влиять на функцию ПЖ через общую межжелудочковую перегородку (МЖП). Дилатация ПЖ за счет увеличения конечной диастолической площади (КДП ПЖ) более 30 см2 (р = 0,012) и конечной систолической площади (КСП ПЖ) более 25 см2 (р = 0,001), увеличение объема правого предсердия (3DE ОПП) более 100 мл (р = 0,036) и уменьшение процента инспираторного коллабирования нижней полой вены (% КНПВ) менее 30% (р = 0,005) продемонстрировали прогностическую значимость у наблюдаемых пациентов. Снижение деформационных свойств ПЖ за счет продольного компонента и нарушение деформации базального сегмента вносит больший вклад в дисфункцию ПЖ (FWLS BS, % &lt; -15% (р &lt; 0,001)).</p></sec><sec><title>Заключение</title><p>Заключение. Нарушение функции ПЖ у больных с СНнФВ ЛЖ является прогностически неблагоприятным фактором, независимо связанным с имеющейся дисфункцией ЛЖ. Наиболее значимыми ультразвуковыми маркерами прогноза выживаемости пациентов с СНнФВ ЛЖ и дисфункцией ПЖ являются показатели деформации миокарда желудочков. Ремоделирование правых камер и нарушение функции ПЖ является пусковым механизмом разобщения ПЖ и легочной артерии, что в конечном итоге приводит к неблагоприятным исходам.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: to determine the ultrasound signs of right heart dysfunction, which increase the prognostic value of the recommended parameters of left ventricular (LV) dysfunction in patients with heart failure with reduced ejection fraction (HFrEF).</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The prospective study included 79 patients with HFrEF LV with clinical manifestations of chronic heart failure functional class III according to the New York Heart Association (HF NYHA Class III) in 52 patients (65.8%) and HF NYHA Class IV in 27 (34.1%). The primary end point was death during a follow-up period of up to 3 years while waiting for heart transplantation.</p></sec><sec><title>Results</title><p>Results. Overall mortality was 33 patients (41.7%), 17 (21.5%) during the 1st year of follow-up. Regression analysis revealed the following independent ultrasound predictors of poor prognosis: LV ejection fraction on 3D-echocardiography (3DE LVEF), p = 0.014; global longitudinal strain of the LV (GLS LV), p = 0.010, and of the interventricular septum basal segment (IVSLS BS), p = 0.012; mean longitudinal strain of the basal segment of the right ventricle free wall (FWLS BS RV), p = 0.003. Changes in the configuration and dilatation of the LV cavity, an increase in LV end-diastolic pressure, impaired contractility, and strain of the LV myocardium can affect the function of the right ventricle (RV) through the common interventricular septum (IVS). Dilatation of the RV due to an increase in the end diastolic area (RV EDA) of more than 30 cm2 (p = 0.012) and end systolic area (RV ESA) of more than 25 cm2 (p = 0.001), an increase in the volume of the right atrium (3DE AKI) of more than 100 ml (p = 0.036), and a decrease in the % inspiratory collapse of the inferior vena cava (% IVC) less than 30% (p = 0.005) demonstrated a prognostic significance in the observed patients. A decrease in the deformation properties of the pancreas due to the longitudinal component and impaired strain of the basal segment makes a greater contribution to RV dysfunction (FWLS BS, % &lt; -15% (p &lt; 0.001)).</p></sec><sec><title>Conclusions</title><p>Conclusions. RV dysfunction in patients with HFrEF is an unfavorable prognostic factor, independently associated with existing LV dysfunction. The most significant ultrasound sign for surveillance prediction of patients with LV HFrEF and RV dysfunction are indicators of ventricular myocardial deformation. Remodeling of the right chambers and dysfunction of the RV is a trigger for the separation of the RV and pulmonary artery, which ultimately leads to adverse outcomes.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>сердечная недостаточность</kwd><kwd>глобальная продольная деформация миокарда</kwd><kwd>правый желудочек</kwd><kwd>фракция выброса</kwd><kwd>дисфункция миокарда</kwd><kwd>предикторы прогноза</kwd></kwd-group><kwd-group xml:lang="en"><kwd>heart failure</kwd><kwd>myocardial global longitudinal strain</kwd><kwd>right ventricle</kwd><kwd>ejection fraction</kwd><kwd>myocardial dysfunction</kwd><kwd>outcome predictors</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>не заявлена</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">Maddox T.M., Januzzi J.L.
