Assessment of the correlation between cardiac remodeling, functional status and electrical remodeling after cardiac resynchronisation therapy (CRT) in patients with non-ischaemic cardiomyopathy.</p></sec><sec><title>Material and methods</title><p>Material and methods. A single center, prospective, observational study included 50 patients with non-ischaemic cardiomyopathy who were candidate for CRT implantation. All patients prior to CRT and then 3 months after implantation had standard 12-lead surface ECGs to assess QRSd for assessment electrical response, for assessment of left ventricular ejection fraction (LVEF) and volumes (left ventricular end diastolic and systolic volume, LVEDV and LVESV), mitral regurgitation (degree of mitral regurgitation), pulmonary artery systolic pressure (for diagnosis of pulmonary hypertension), NYHA class and 6 minute walk test (6MWT) to assess patient’s functional capacity.</p></sec><sec><title>Results</title><p>Results. 50 patients with CRT were included (35 males and 15 females, mean age 54.88±7.48 years). All patients were in sinus rhythm with QRS duration (QRSd) ≥120 ms, EF&lt;35% and left bundle branch block. After 3 months; there was significant improvement in QRSd in 82% of the cases (145.3±16.3 ms vs 133.3±17.2 ms, p&lt;0.001). NYHA class improved at least one class in 78% and 6 min walk test improved in 80% (168.5 [131.0; 181.0] m vs 280.0 [237.0; 297.0] m, p&lt;0.001). LVEF increased significantly in 74% of study cases (28.6±2.7 vs 34.5±3.1, p value 0.001) also there were statistically significant improvement in LVEDV (267.0±45.7 to 221.8±41.9 ml, p=0.002) and LVESV (137.43±47.19 to 105.03±42.7 ml, p=0.003). There was statistically significant correlation between QRSd and NYHA class (r=0.392, p=0.005), QRSd and 6MWT (r=0.323, p=0.022) and QRSd with LVEF (r=0.672 with p&lt;0.001). Only seven patients showed improvement in the 3 parameters: LVESV, QRS duration and 6 min walk test.</p></sec><sec><title>Conclusion</title><p>Conclusion. The CRT-pacemaker implantation was associated with significant improvement in QRSd, NYHA class, 6MWT and LV volumes in the short-term period. QRSd improvement was significantly correlated with functional status and LV EF.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цель</title><p>Цель. Оценить у пациентов с неишемической кардиомиопатией взаимосвязь между ремоделированием сердца, функциональным классом сердечной недостаточности и электрическим ремоделированием после сердечной ресинхронизирующей терапии (СРТ).</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В исследование включены 50 пациентов с неишемической кардиомиопатией, которым провели имплантацию СРТ. Всем пациентам исходно и через 3 мес после имплантации CRT проводилась стандартная ЭКГ в 12 отведениях для оценки QRSd (оценки электрического ответа), трансторакальная эхокардиография для оценки фракции выброса (ФВ) и объемов левого желудочка (конечный диастолический и систолический объем левого желудочка, КДО ЛЖ и КСО ЛЖ), митральной регургитации (степень митральной регургитации), систолического давления в легочной артерии (для диагностики легочной гипертензии), оценка функционального класса по NYHA и тест 6-минутной ходьбы (ТШХ) для оценки функциональных возможностей пациента.</p></sec><sec><title>Результаты</title><p>Результаты. Средний возраст пациентов (35 мужчин и 15 женщин) составил 54,9±7,5 года. У всех пациентов — синусовый ритм (длительность QRS ≥120 мс), ФВ &lt;35% и блокада левой ножки пучка Гиса. Через 3 мес после имплантации СРТ в 82% случаев наблюдалось значимое изменение QRS (145,3±16,3 мс по сравнению с 133,3±17,2 мс, p&lt;0,001). Класс NYHA улучшился по крайней мере на один у 78% пациентов, а показатели ТШХ — у 80% (168,5 [131,0; 181,0] м против 280,0 [237,0; 297,0] м, р&lt;0,001). ФВ ЛЖ статистически значимо увеличилась у 74% пациентов (28,6±2,7 против 34,5±3,1, р&lt;0,001), также значимо улучшились показатели: КДО ЛЖ (с 267,0±45,7 до 221,8±41,9 мл (р=0,002) и КСО ЛЖ (с 137,4±47,2 до 105,0±42,7 мл, р=0,003). Наблюдалась статистически значимая корреляция между продолжительностью интервала QRS и классом NYHA (r=0,392, p=0,005), QRS и результатом ТШХ (r=0,323, p=0,022) и длительностью QRS с ФВ ЛЖ (r=0,672 при p&lt;0,001). Только у семи пациентов наблюдалось улучшение по всем трем параметрам: ФВ ЛЖ, длительность QRS и ТШХ.</p></sec><sec><title>Заключение</title><p>Заключение. Проведение СРТ ассоциировалась со значительным улучшением показателей: длительность QRS, класс NYHA, дистанции в ТШХ и объем ЛЖ уже в краткосрочном периоде. Улучшение длительности интервала QRS значительно коррелировало с функциональным статусом и ФВ ЛЖ.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>CRT</kwd><kwd>ремоделирование сердца</kwd><kwd>сердечная недостаточность</kwd><kwd>класс NYHA</kwd></kwd-group><kwd-group xml:lang="en"><kwd>CRT</kwd><kwd>cardiac remodeling</kwd><kwd>heart failure</kwd><kwd>NYHA class</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проведено при поддержке Университета Бенха и Национального кардиологического института</funding-statement><funding-statement xml:lang="en">The study was performed with the support of Benha University and National Heart Institute</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">Thomas G, Kim J, Lerman BB.
