Оценить возможности нагрузочной радионуклидной томовентрикуло-графии (РТВГ) в прогнозировании повторного ремоделирования левого желудочка (ЛЖ) в отдаленном периоде после хирургического лечения ишемической кардиомиопатии.Материал и методы. Тридцати пациентам с диагнозом ишемической кардиомиопатии перед хирургической коррекцией была выполнена РТВГ в покое и на фоне возрастающих доз допамина по протоколу 5/10/15 мкг/кг/мин (5 мин/ дозировка). Всем пациентам до операции, в раннем послеоперационном периоде (7-14 дней) и в отдаленном периоде выполнялась двухмерная эхокардиография. На основании данных последней в отдаленном послеоперационном периоде (476±36 дней) пациенты были разделены на две группы: группа 1 (n=19) — пациенты с продолжающимся ремоделированием ЛЖ (увеличение конечно-систолического объема ЛЖ или снижение его &lt;10% относительно раннего послеоперационного периода), группа 2 (n=11) — пациенты с уменьшением конечно-систолического объема ЛЖ &gt;10%.Результаты. Исследование на фоне стресс-теста выявило значимые различия между группами в показателях динамики (Δ) фракции выброса (ФВ) ЛЖ (%) (2 (2;8); 11 (5;12); p=0,02), максимальной скорости изгнания ЛЖ (%) (32 (14;51); 63 (34;79); p=0,009), показателей диссинхронии ЛЖ (PSDo (3 (0;7); -2 (-9;3); p=0,004); Entropy (%) (2 (-1;6); 0 (-4;2); p=0,01). Однофакторный регрессионный анализ показал, что прогностическую ценность имеют ΔФВ ЛЖ (отношение шансов (ОШ)=0,88; доверительный интервал (ДИ) 0,8; 0,97; р=0,008), ΔPSD ЛЖ (ОШ=1,13; ДИ 1,03; 1,25; р=0,005), количество коронарных артерий со стенозированием &gt;75% (ОШ=4,25; ДИ 1,57; 11,48; р=0,001). По данным ROC-анализа значения чувствительности, специфичности и AUC равнялись 87%, 64% и 0,727 для ΔPSD ЛЖ (пороговое значение &gt;-1); 84%, 46% и 0,691 для КС &gt;75% (пороговое значение &gt;2); 65%, 82% и 0,674 для ΔФВ ЛЖ (пороговое значение ≤4), соответственно. Логистическая модель, включающая данные показатели и наличие у пациента сахарного диабета, продемонстрировала значимо большее значение площади под кривой (0,907; р&lt;0,05) по сравнению с данными показателями, взятыми раздельно.Заключение. Дооперационные показатели ΔФВ ЛЖ и ЛPSD ЛЖ, полученные при нагрузочной РТВГ, обладают прогностической значимостью в аспекте повторного ремоделирования миокарда ЛЖ в отдаленном послеоперационном периоде.</p></sec></abstract><trans-abstract xml:lang="en"><p>Aim. To assess the potential of stress tomographic radionuclide ventriculography (T-RVG) in long-term prognosis of left ventricular (LV) re-remodeling after surgery of ischemic cardiomyopathy.Material and methods. Thirty patients with ischemic cardiomyopathy, before surgical treatment, underwent resting T-RVG and with increasing doses of dopamine (5/10/15 pg/kg/min (5 min/dose). All patients underwent two-dimensional echocardiography before surgery, in the short- (7-14 days) and long-term postoperative period. In the long-term postoperative period (476±36 days), the patients were divided into two groups: group 1 (n=19) — patients with ongoing LV remodeling (increase in the LV end-systolic volume (ESV) or decrease &lt;10% relatively short-term postoperative period), group 2 (n=11) — patients with decreased LV ESV &gt;10%.Results. The results revealed significant differences between the groups in the dynamics (Δ) of the LV ejection fraction (EF) (%) (2 (2;8); 11 (5;12), p=0,02), peak ejection rate (%) (32 (14;51); 63 (34;79), p=0,009), LV dyssynchrony (PSDo (3 (0;7); -2 (-9;3), p=0,004); Entropy (%) (2 (-1;6); 0 (-4;2), p=0,01)). Univariate regression showed that ΔLVEF (odds ratio (OR), 0,88; confidence interval (CI), 0,8; 0,97; p=0.008), ΔLVPSD (OR, 1,13; CI, 1,03; 1,25; p=0,005), and coronary stenosis &gt;75% (OR, 4,25; CI, 1,57; 11,48; p=0,001) had a predictive value. According to the ROC-analysis, the sensitivity, specificity, and AUC were 87%, 64% and 0,727 for ΔLVPSD (threshold &gt;-1); 84%, 46% and 0,691 for coronary stenosis &gt;75% &gt;75% (threshold &gt;2); 65%, 82% and 0,674 for ΔLVEF (threshold ≤4), respectively. The logistic model, which included these parameters and the presence of diabetes, showed a significantly greater AUC (0,907, p&lt;0,05) compared with these indicators taken separately.Conclusion. Preoperative values of ΔLVEF and ΔLVPSD obtained with stress T-RVG have prognostic significance in relation to LV long-term re-remodeling.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ишемическая кардиомиопатия</kwd><kwd>ремоделирование</kwd><kwd>радионуклидная томовентрикулография</kwd><kwd>прогноз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ischemic cardiomyopathy</kwd><kwd>remodeling</kwd><kwd>tomographic radionuclide ventriculography</kwd><kwd>prognosis</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">Patel P, Ivanov A, Ramasubbu K.
