Оценить влияние двух стратегий имплантации левожелудочкового электрода на развитие сердечно-сосудистых событий у пациентов с хронической сердечной недостаточностью.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Текущее рандомизированное контролируемое клиническое исследование разработано для сравнения эффективности традиционной анатомической стратегии позиционирования электрода левого желудочка (ЛЖ) и имплантации под контролем электрокардиографии в оптимальную ветвь венозного коронарного синуса, которая является наиболее близкой к последней электрически активной области миокарда.</p></sec><sec><title>Результаты</title><p>Результаты. В исследование было включено 63 пациента с хронической сердечной недостаточностью III или IV функционального класса по NYHA с желудочковой диссинхронией, фракцией выброса (ФВ) ЛЖ &lt;35%, конечным диастолическим размером ЛЖ &gt;150 мл, интервалом QRS &gt;130 мс. Продолжительность жизни при электрокардиографическом подходе (основная группа) составила 11,22 мес., что было значительно ниже при анатомическом подходе (контрольная группа). Время до повторной госпитализации в основной группе было почти в два раза больше по сравнению с пациентами контрольной группы (10,188 мес. vs 5,548 мес.). ФВ ЛЖ была значительно выше в основной группе — медиана составила 39%, в то время как в контрольной группе она была 35% (р=0,002).</p></sec><sec><title>Заключение</title><p>Заключение. Результаты настоящего исследования показывают, что электрокардиографический подход имеет преимущества по сравнению с традиционным анатомическим подходом с точки зрения улучшения структуры и функции сердца у пациентов с сердечной недостаточностью III и IV классов по NYHA, связанной с желудочковой диссинхронией.</p></sec></abstract><trans-abstract xml:lang="en"><p>There is a variety of cardiac resynchronization therapy (CRT) strategies and none has ultimate benefits over the others.</p><sec><title>Aim</title><p>Aim. To evaluate the influence of two strategies of left ventricular (LV) electrode implantation on the development of cardiovascular events in patients with chronic cardiac failure.</p></sec><sec><title>Material and methods</title><p>Material and methods. This was a randomized controlled clinical trial designed to compare the effectiveness of traditional anatomy-guided LV lead positioning strategy towards the electrocardiography-guided implantation approach in an optimal branch of the coronary sinus vein, being the closest to the latest electrically activated myocardial region.</p></sec><sec><title>Results</title><p>Results. We enrolled 63 patients with NYHA class III or IV chronic heart failure with ventricular dyssynchrony, an LV ejection fraction (LVEF) less than 35%, an LV end diastolic dimension exceeding 150 ml, a QRS interval over 130 ms. The survival time in electrocardiography-guided approach (study group) was equal to 11,22 months, which was significantly lower in the anatomy-guided approach (control group). Time to re-hospitalization in a study group was nearly two times longer as compared with that in patients from the control group (10,188 months versus 5,548 months). LVEF was significantly higher in the study group with median value equal to 39% versus that in the control group equal to 35% (р=0,002).</p></sec><sec><title>Conclusions</title><p>Conclusions. The results of the present study demonstrate that electrocardiographyguided approach has benefits over traditional anatomy-guided approach in terms of improved cardiac structure and function in patients with NYHA class III and IV heart failure associated with ventricular dyssynchrony.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>сердечная ресинхронизирующая терапия</kwd><kwd>ресинхронизация</kwd><kwd>комплекс QRS</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cardiac resynchronization therapy</kwd><kwd>resynchronization</kwd><kwd>QRS complex</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">Dauw J, Martens P, Mullens W.
