Определить прогностическую значимость регионарной механической диссинхронии (МД) сердца, оцененной методом радионуклидной равновесной томовентрикулографии (РТВГ) у пациентов-кандидатов на сердечную ресинхронизирующую терапию (СРТ).</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В исследование было включено 65 пациентов с показаниями для проведения СРТ, согласно современным рекомендациям. Перед СРТ всем пациентам была выполнена РТВГ для оценки контрактильной функции и МД сердца. По данным фазового анализа оценивали показатели глобальной и регионарной МД сердца: стандартное отклонение фазовой гистограммы (PSD), ширина фазовой гистограммы (HBW), энтропия, а также оценивали межжелудочковую диссинхронию. Регионарная оценка включала в себя оценку фазовых гистограмм, полученных при анализе сокращения отдельных стенок: передней, боковой, задней стенки левого желудочка (ЛЖ), свободной стенки правого желудочка (ПЖ) и межжелудочковой перегородки. Для оценки эффективности лечения через 6 мес. после СРТ всем пациентам была проведена эхокардиография, на основании которой пациентов подразделяли на группы респондеров и нереспондеров.</p></sec><sec><title>Результаты</title><p>Результаты. По данным РТВГ, между группами респондеров и нереспондеров были выявлены статистически значимые различия исходных регионарных показателей МД: у респондеров значения МД свободной стенки ПЖ (PSD: 39 (28-67) vs 28 (20-50) град, p=0,03) и передней стенки ЛЖ (PSD: 28,5 (16-40) vs 14 (11-24) град, p=0,0005) были выше, а боковой стенки ЛЖ — ниже (PSD: 10 (7-14) vs 15 (9-26) град, p=0,007), чем у нереспондеров. По данным многофакторного логистического регрессионного анализа, включающего клинико-демографические и сцинтиграфические данные, было установлено, что независимыми предикторами положительного ответа на СРТ являются: ишемическая этиология хронической сердечной недостаточности, HBW ЛЖ, PSD свободной стенки ПЖ, PSD передней стенки, HBW боковой стенки ЛЖ (p&lt;0,001). Чувствительность и специфичность полученной модели составили 93% и 91%, соответственно.</p></sec><sec><title>Заключение</title><p>Заключение. Регионарные сцинтиграфические индексы МД повышают прогностическую ценность РТВГ у кандидатов на СРТ. Наиболее информативными в этом плане являются PSD свободной стенки ПЖ и передней стенки ЛЖ, а также HBW боковой стенки ЛЖ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To determine the prognostic significance of cardiac regional mechanical dyssynchrony (MD), assessed by radionuclide equilibrium ventriculography (REVG) in candidates for cardiac resynchronization therapy (CRT).</p></sec><sec><title>Material and methods</title><p>Material and methods. The study included 65 patients with indications for CRT according to current guidelines. Prior to CRT, all patients underwent REVG to assess cardiac contractile function and MD. According to the phase analysis, indicators of global and regional cardiac MD were evaluated: phase standard deviation (PSD), histogram band width (HBW), entropy, and interventricular dyssynchrony. The regional assessment included an evaluation of phase histograms obtained from the analysis of the contraction of certain walls: left ventricular (LV) anterior, lateral, posterior wall, right ventricular (RV) free wall, and the interventricular septum. To evaluate the effectiveness of treatment 6 months after CRT, all patients underwent echocardiography, on the basis of which patients were divided into groups of responders and non-responders.</p></sec><sec><title>Results</title><p>Results. REVG revealed significant differences in the initial regional MD values between the groups of responders and non-responders: in responders, MD values of RV free wall (PSD: 39 (28-67) vs 28 (20-50), p=0,03) and LV anterior wall (PSD: 28,5 (16-40) vs 14 (11-24), p=0,0005) were higher, and the LV lateral wall was lower (PSD: 10 (7-14) vs 15 (9-26), p=0,007) than in non-responders. Multivariate logistic regression found following independent predictors of a positive response to CRT: heart failure of ischemic origin, LV HBW, RV free wall PSD, anterior wall PSD, LV lateral wall HBW (p&lt;0,001). The sensitivity and specificity of the model was 93% and 91%, respectively.</p></sec><sec><title>Conclusion</title><p>Conclusion. Regional MD scintigraphy parameters increase the predictive value of REVG in CRT candidates. The most informative in this regard are the PSD of RV free wall and LV anterior wall, as well as the HBW of LV lateral wall.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>механическая диссинхрония</kwd><kwd>регионарный анализ</kwd><kwd>радионуклидная томовентрикулография</kwd><kwd>сердечная ресинхронизирующая терапия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mechanical dyssynchrony</kwd><kwd>regional analysis</kwd><kwd>radionuclide ventriculography</kwd><kwd>cardiac resynchronization therapy</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">Cleland JG, Freemantle N, Erdmann E, et al.
