Изучить деформационные показатели миокарда левого желудочка (ЛЖ), определяемые методом двухмерного стрейна, для оценки предполагаемой пользы от имплантации кардиовертера-дефибриллятора с целью первичной профилактики внезапной сердечной смерти.</p><p>Материал и методы исследования. В данное исследование было включено 133 пациента с хронической сердечной недостаточностью NYHA 3-4 функционального класса с фракцией выброса ЛЖ ≤35%, принимающих оптимальную медикаментозную терапию. Проводилась speckle-tracking эхокардиография с оценкой показателей деформации ЛЖ (сегментарные стрейны, глобальный продольный и циркулярный стрейн [GLS и GCS, соответственно]), после чего с целью первичной профилактики внезапной сердечной смерти проводилась имплантация кардиовертера-дефибриллятора. Включенные в исследование пациенты проспективно наблюдались в течение двух лет после операции (визиты в клинику через 3, 6, 12, 18, 24 месяцев) для регистрации впервые возникших пароксизмов желудочковых тахиаритмий (ЖТ) и оценки однолетней сердечно-сосудистой летальности.</p></sec><sec><title>Результаты</title><p>Результаты. Аритмическая конечная точка возникла у 27 больных (20%), 19 больных (14%) умерло по причине острой декомпенсации хронической сердечной недостаточности. Сравнительный анализ исследуемых параметров деформации ЛЖ не выявил статистически значимых различий в группах выживших и умерших больных. Больные с ЖТ имели худшие деформационные характеристики. Было установлено, что при абсолютных значениях GLS &lt;6% риск первой манифестации ЖТ в течение периода наблюдения повышался почти в 3 раза (отношение шансов (ОШ)=2,59; 95% доверительный интервал (ДИ): 1,07-6,26; р=0,031). Вторым независимым предиктором аритмической точки стала величина продольного стрейна передней стенки (ОШ=1,28; 95% ДИ: 1,14-1,45; р=0,0001 при однофакторном анализе и ОШ=1,55; 95% ДИ: 1,18-2,04; р=0,002 при многофакторном анализе). По результатам многофакторного анализа с включением показателей деформации миокарда, возраста, пола и наличия ишемической болезни сердца была получена прогностическая моделей, позволяющая прогнозировать ЖТ с чувствительностью 71%, специфичностью 97%. Площадь под кривой составила 0,916 (95% ДИ: 0,850-0,981; р=0,0001).</p></sec><sec><title>Выводы</title><p>Выводы. Показатели деформации миокарда ЛЖ не помогают в прогнозировании сердечно-сосудистой летальности, но могут оказаться полезными при стратификации риска ЖТ. Для достижения этой цели может использоваться не только значение GLS, но и сегментарная карта регионарных стрейнов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To study the impact of left ventricle (LV) deformation parameters by the two-dimensional strain method to assess the intended use of cardioverter defibrillator implantation for primary prevention of sudden cardiac death.</p></sec><sec><title>Methods</title><p>Methods. The study included 133 patients with congestive heart failure NYHA 3-4 functional class with a LV ejection fraction ≤35%, taking optimal drug therapy. The speckle-tracking echocardiography with the estimation of LV deformation indicators (segmental strains, global longitudinal and circular strain [GLS and GCS, respectively]) was carried out, after which the implantation of defibrillator for the purpose of primary prevention of sudden death was performed. The patients enrolled in the study were observed prospectively for two years after the operation (visits to the clinic after 3, 6, 12, 18, 24 months) for the registration of first-time ventricular tachyarrhythmias (VT) paroxysms and assessment of one-year cardiovascular mortality.</p></sec><sec><title>Results</title><p>Results. The arrhythmic endpoint appeared in 27 patients (20%), 19 patients (14%) died due to acute decompensation of heart failure. Comparative analysis of the studied parameters of LV deformation did not reveal statistically significant differences in the groups of survivors and deceased patients. Patients with VT had the worst deformation characteristics. It was found that at absolute values of GLS&lt;6% the risk of the first VT manifestation during the observation period increased almost threefold (odds ratio (OR)=2.59; 95% confidence interval (CI): 1.07-6.26; p=0.031). The second independent predictor of the arrhythmic point was the longitudinal strain of the anterior wall (OR=1.28; 95%CI: 1.14-1.45; p=0.0001 for univariate analysis and OR=1.55; 95%CI: 1.18-2.04; p=0.002 for multivariate analysis). Based on the multifactor analysis, which included indicators of myocardial deformation, age, sex, and ischemic heart disease, predictive model was obtained to predict VT with 71% sensitivity and 97% specificity. The area under the curve was 0.916 (95%CI: 0.850-0.981; p=0.0001).</p></sec><sec><title>Conclusion</title><p>Conclusion. LV deformation parameters do not help to predict cardiovascular mortality, but may be useful in stratification of VT risk. To achieve this GLS value as well as the segmental map of regional strains can be used.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>хроническая сердечная недостаточность</kwd><kwd>деформация миокарда</kwd><kwd>левый желудочек</kwd><kwd>кардиовертер-дефибриллятор</kwd><kwd>желудочковые тахиаритмии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chronic heart failure</kwd><kwd>myocardial deformation</kwd><kwd>left ventricle</kwd><kwd>cardioverter defibrillator</kwd><kwd>ventricular tachyarrhythmias</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">Бойцов СА.
