В исследование было включено 110 пациентов (56 женщин), средний возраст которых составил 47,7±10,9 лет, с хронической сердечной недостаточностью (ХСН) III функционального класса (ФК) по NYHA с основным диагнозом “дилатационная кардиомиопатия” (ДКМП) и зарегистрированной постоянной формой ФП. Ширина комплекса QRS варьировала от 146 до 240 мс (средняя - 183±32 мс). Фракция выброса (ФВ) левого желудочка (ЛЖ), по данным эхокардиографии (ЭхоКГ), составила 30,1±3,8%, конечно-диастолический объем (КДО) составил 272,4±49,8 мл. Дистанция 6-минутной ходьбы составила 247,8±57,3 м. Оптимальная медикаментозная терапия ХСН была неэффективной на протяжении срока от 3 до 6 мес. Всем пациентам были имплантированы устройства для сердечной ресинхронизирующей терапии (СРТ). Контрольное обследование на фоне бивентрикулярной стимуляции было проведено через 36 мес. Анализ результатов СРТ в срок 36 мес. показал, что у 84 (76,4%) пациентов, имевших до начала лечения ФП и неэффективную антиаритмическую терапию, самопроизвольно восстановился синусовый ритм (СР). В этой группе за 3 года наблюдения Фв изменилась с 29,0±3,8 до 42,5±4,2% (р&lt;0,0001), прирост составил 18%, а КДО уменьшился с 215,9±58,1 до 177,1±26,6 мл (p&lt;0,0005), в среднем на 48 мл. У 26 (23,6%) пациентов в течение 36 мес. сохранилась ФП, в их группе за 3 года наблюдения ФВ ЛЖ увеличилась с 29,0±3,8 до 38,7±2,1%, а прирост составил 9%, КДО уменьшился с 215,9±58,1 до 200,7±39,1 мл (p&lt;0,0005), в среднем на 15 мл. Таким образом, у пациентов с ДКМП и тяжелой СН достижение СР является важной задачей, поскольку позволяет, как показывает наше исследование, добиться стабильного прироста ФВ и уменьшения размеров КДО на всем сроке проведения СРТ.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the study was to evaluate impact of atrial fibrillation on efficacy of cardiac resynchronization therapy (CRT) in patients with severe heart failure. The study comprised 110 patients (56 women) aged 47.7±10.9 years with NYHA functional class III chronic heart failure (CHF), main diagnosis of dilated cardiomyopathy (DCM), and registered permanent form of atrial fibrillation (AF). The QRS width varied from 146 ms to 240 ms (average 183±32 ms); left ventricular ejection fraction (EF) was 30.1±3.8%; end diastolic volume (EDV) was 272.4±49.8 mL; and 6-minute walk distance was 247.8±57.3 m. Optimal drug therapy for CHF was inefficacious in these patients during three to six months. All patients were implanted with CRT device. Follow up examination in the presence of biventricular stimulation was conducted after 36 months of therapy. The analysis of the results of 36-month-long CRT demonstrated that sinus rhythm spontaneously restored in 84 patients (76.4%) who had AF and inefficacious antiarrhythmic therapy before the beginning of CRT. During three years of the study, EF increased in this patients’ group by 18% from 29.0±3.8% to 42.5±4.2% (р&lt;0.0001); EDV decreased by 48 mL from 215.9±58.1 mL to 177.1±26.6 mL (p&lt;0.0005). Atrial fibrillation did not resolve in 26 patients (23.6%) during 36 months. In these patients, LV EF increased by 9% from 29.0±3.8% to 38.7±2.1%; EDV decreased by 15% from 215.9±58.1 mL to 200.7±39.1 mL (p&lt;0.0005). In conclusion, restoration of sinus rhythm is an important task in patients with DCM and severe heart failure because, according to our study, it enables to achieve stable EF increase and EDV decrease for the entire period of CRT.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сердечная ресинхронизирующая терапия</kwd><kwd>фибрилляция предсердий</kwd><kwd>дилатационная кардиомиопатия</kwd><kwd>cardiac resynchronization therapy</kwd><kwd>atrial fibrillation</kwd><kwd>dilated cardiomyopathy</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">Рекомендации по электрокардиостимуляции и сердечной ресинхронизирующей терапии ESC 2013 // Рос. кардиологический журнал. - 2004. - № 4(108).</mixed-citation><mixed-citation xml:lang="en">Рекомендации по электрокардиостимуляции и сердечной ресинхронизирующей терапии ESC 2013 // Рос. кардиологический журнал. - 2004. - № 4(108).</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Faran A. et al.
