To evaluate clinical, morphological, functional features and mortality level in patients with different value of left ventricular reverse remodeling after cardiac resynchronization therapy (CRT). Materials and methods. The study enrolled 112 patients (mean age 54.6±9.9 years, 83.5% men) with left ventricular ejection fraction (LVEF) І35%, NYHA functional class II-IV. We enrolled patients with QRS width &gt;120 ms or QRS &lt;120 ms + 3 parameters of mechanical dyssynchrony by echocardiography. Clinical, electrocardiographic and echocardiographic parameters were evaluated at baseline, 1, 3 months and each 6 months after implantation. Three patients with increase of left ventricular end - systolic volume (LVESV) were excluded from prospective trial due to lack of full follow - up data. According to the best decrease of LVESV (mean follow - up period 34.8±16.7 months) patients were classified as non - progressors (n=18; decrease in LVESV &lt;15%), responders (n=41; decrease in LVESV 15-29%) and super - responders (SR) (n=50; reduction in LVESV ≥30%). Results. At baseline groups were matched for main clinical characteristics, the proportion of patients with atrial fibrillation, width of the QRS complex, and the presence of left bundle - branch block. Echocardiographic parameters didn’t differ between the groups. All groups demonstrated significant reverse remodeling of the left ventricle, increase in LVEF, increase in 6-minute walking distance. SR demonstrated the best improvement of clinical and functional parameters after CRT. However, improvement in LVEF, LVESV, NYHA functional class between responders and non - progressors were found similar. Dynamics of these parameters were comparable. The survival rates were 100% in SR, 80% in responders and 88.9% in non - progressors (Log-Rank test p=0.001). Survival rates in responders and non - progressors didn’t differ significantly (Log-Rank test p=0.150). Conclusion. Patients with reduction in LVESV less than 15% demonstrate improvement in clinical status, LVEF and survival rates compared to subjects with reduction in LVESV 15-29%. Non - progressors demonstrate similar survival as responders in long - term period. Taking into account the natural course of CHF functional stabilisation and absence of CHF progression in patients with lack of left ventricular reverse remodelling is a variant of good response and these patients should not be identified as non - responders.</p></abstract><trans-abstract xml:lang="ru"><p>Всегда ли недостаточная динамика параметров левого желудочка свидетельствует о плохом ответе на сердечную ресинхронизирующую терапию? Цель исследования. Выявить клинические и морфофункциональные особенности, оценить отдаленную выживаемость у больных с хронической сердечной недостаточностью (ХСН) в группах в зависимости от выраженности обратного ремоделирования левого желудочка (ЛЖ) на фоне сердечной ресинхронизирующей терапии (СРТ). Материалы и методы. В исследование включено 112 человек (83,5% мужчин, средний возраст 54,6±9,9 года) со сниженной фракцией выброса (ФВ) ЛЖ І35%, II-IV функциональным классом (ФК) ХСН по NYHA, шириной комплекса QRS &gt;120 мс. При ширине QRS &lt;120 мс учитывалось наличие как минимум трех критериев механической диссинхронии по результатам эхокардиографии. Средний срок наблюдения составил 34,8±16,7 мес. Исходно, через 1 мес, 3 мес и каждые последующие 6 мес проводились клиническое обследование, электрокардиография, эхокардиография. Три пациента с увеличением конечно - систолического объема (КСО) ЛЖ в динамике не вошли в проспективное исследование в связи с отсутствием возможности полноценного динамического наблюдения. По динамике КСО ЛЖ пациенты разделены на группы: непрогрессоры (снижение &lt;15%; n=18), респондеры (снижение 15-29%; n=41), суперреспондеры (снижение ≥30%; n=50). Результаты. Исходно группы сопоставимы по основным клиническим характеристикам. Все группы продемонстрировали значимое увеличение ФВ ЛЖ, повышение толерантности к физической нагрузке, уменьшение ФК ХСН по NYHA. Межгрупповой анализ не выявил достоверных различий между непрогрессорами и респондерами по уровням средних значений клинических и функциональных показателей как исходно, так и на пике ответа. Отдаленная выживаемость суперреспондеров составила 100%, респондеров - 78%, непрогрессоров - 88,9% (Log-Rank test p=0,001). При сравнении выживаемости между непрогрессорами и респондерами различия оказались недостоверными (Log-Rank test p=0,150). Заключение. Пациенты со снижением КСО ЛЖ &lt;15% демонстрируют сопоставимую динамику клинических и функциональных показателей на фоне СРТ в сравнении с пациентами со снижением КСО ЛЖ 15-29%, а также сопоставимые уровни отдаленной выживаемости. С учетом прогрессирующего течения ХСН, стабилизация состояния с развитием незначительного обратного ремоделирования ЛЖ не должна рассматриваться как вариант отсутствия ответа на СРТ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>cardiac resynchronization therapy</kwd><kwd>responders</kwd><kwd>non progressors</kwd><kwd>chronic heart failure</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>сердечная ресинхронизирующая терапия</kwd><kwd>респондеры</kwd><kwd>непрогрессоры</kwd><kwd>хроническая сердечная недостаточность</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Мареев В.Ю., Агеев Ф.Т., Арутюнов Г.П., Коротеев А.В., Мареев Ю.В., Овчинников А.Г., Беленков Ю.Н., Васюк Ю.А., Галявич А.С., Гарганеева А.А., Гиляревский С.Р., Глезер М.Г., Козиолова Н.А., Коц Я.И., Лопатин Ю.М., Мартынов А.И. , Моисеев В.С., Ревишвили А.Ш., Ситникова М.Ю., Скибицкий В.В., Соколов Е.И., Сторожаков Г.И., Фомин И.В., Чесникова А.И., Шляхто Е.В.
