Оценить динамику показателей неинвазивной миокардиальной работы левого желудочка (ЛЖ) у пациентов с хронической сердечной недостаточностью с низкой фракцией выброса (ХСНнФВ) и дефицитом железа (ДЖ) после терапии карбоксимальтозатом железа (ЖКМ).</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Критерии включения: фракция выброса (ФВ) ЛЖ ≤40%, ДЖ (ферритин &lt;100 нг/мл или ферритин 100-299 нг/мл при коэффициенте насыщения трансферрина железом &gt;&lt;20%), уровень гемоглобина от 100 до 140 г/л, масса тела &gt;70 кг, получение оптимальной медикаментозной терапии (ОМТ) в рекомендуемых дозах в соответствии с рекомендациями Европейского общества кардиологов и Российского общества кардиологов. Медиана возраста 67±11,7 лет, 83% — мужчины, медиана ФВ ЛЖ 29%, медиана N-концевого промозгового натрийуретического пептида 315 нг/мл. Пациенты были рандомизированы методом конвертов. Первую группу составили 19 пациентов, получивших терапию 1500 мг ЖКМ внутривенно за 2 введения с интервалом в одну неделю между инъекциями в дополнение к ОМТ. Контрольную группу составили 16 пациентов, получавших ОМТ без назначения ЖКМ. Всем пациентам проводили стандартное эхокардиографическое исследование, дополнительно определяли показатели неинвазивной миокардиальной работы ЛЖ непосредственно перед включением в исследование и через 3 мес.</p></sec><sec><title>Результаты</title><p>Результаты. У первой группы пациентов на фоне терапии ЖКМ выявлено увеличение ФВ ЛЖ (29,1±10,3 vs 35,4±11,1; p=0,001), систолической экскурсии фиброзного кольца митрального клапана (1,2 (1;1,6) vs 1,5 (1,3;1,9), p=0,001), глобальной продольной деформации ЛЖ (-7 (-5;-8) vs -8 (-6;-11), p=0,007) и неинвазивных показателей миокардиальной работы (глобальный индекс миокардиальной работы (826±314 vs 1041±354), p=0,0001; глобальная конструктивная работа (1173±388 vs 1435±405), p=0,0001; эффективность глобальной работы (85 (82;87) vs 86 (82;88), p=0,017)). В группе ОМТ не было выявлено достоверных изменений изучаемых параметров.</p></sec><sec><title>Заключение</title><p>Заключение. У пациентов с ХСНнФВ и ДЖ, получавших ЖКМ, было выявлено достоверное увеличение систолической функции ЛЖ, включая неинвазивные индексы миокардиальной работы, по сравнению с контрольной группой. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To assess non-invasive parameters of left ventricular (LV) myocardial work in patients with heart failure with reduced ejection fraction (CHrEF) and iron deficiency (ID) after ferric carboxymaltose (FCM) therapy.</p></sec><sec><title>Material and methods</title><p>Material and methods. There were following inclusion criteria: LV ejection fraction (EF) ≤40%; body &gt;70 kg, receiving best medical therapy (BMT) in recommended doses in accordance with the guidelines of the European Society of Cardiology and the Russian Society of Cardiology. Median age was 67±11,7 years (men, 83%), while median LVEF and N-terminal pro-brain natriuretic peptide was 29% and 315 ng/ml, respectively. Patients were randomized by the envelope method. The first group consisted of 19 patients who received therapy with intravenous FCM 1500 mg in 2 injections with an interval of one week between injections in addition to BMT. The control group consisted of 16 patients who received BMT without FCM. All patients underwent a standard echocardiography, and non-invasive LV myocardial work was assessed immediately before inclusion in the study and after 3 months.</p></sec><sec><title>Results</title><p>Results. In the first group of patients receiving FCM therapy, an increase in LVEF (29,1±10,3 vs 35,4±11,1; p=0,001), mitral annular plane systolic excursion (1,2 (1;1,6 ) vs 1,5 (1,3;1,9), p=0,001), LV global longitudinal strain (-7 (-5;-8) vs -8 (-6;-11), p=0,007) and non-invasive indicators of myocardial work (global work index (826±314 vs 1041±354), p=0,0001; global constructive work (1173±388 vs 1435±405), p=0,0001; global work efficiency (85 (82;87) vs 86 (82;88), p=0,017)). There were no significant changes in the studied parameters in the BMT group.</p></sec><sec><title>Conclusion</title><p>Conclusion. Patients with HFrEF and ID treated with FCM showed a significant increase in LV systolic function, including non-invasive myocardial work parameters, compared with the control group. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>хроническая сердечная недостаточность с низкой фракцией выброса</kwd><kwd>дефицит железа</kwd><kwd>миокардиальная работа</kwd></kwd-group><kwd-group xml:lang="en"><kwd>heart failure with reduced ejection fraction</kwd><kwd>iron deficiency</kwd><kwd>myocardial work</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">Pellikka PA, She L, Holly TA, et al.
