To study the long-term effects of complex therapy with the addition of enhanced external counterpulsation (EECP) in patients with stable coronary artery disease (CAD) complicated by chronic heart failure (CHF).</p></sec><sec><title>Material and methods</title><p>Material and methods. In the open randomized trial EXCEL (NCT05913778), 118 Patients with the verified ischemic CHF NYHA class II-III with reduced or intermediate left ventricular ejection fraction were included. They were randomized into group 1 (n=59) — optimal medical therapy (OMT) and EECP (35 hours, 2 courses per year), group 2 (n=59) — OMT and EECP (35 hours, 1 course per year). The primary endpoint was the proportion of patients with a 6-minute walk test (6MWT) increase of at least 20% from baseline. The secondary composite endpoint included adverse cardiovascular clinical outcomes (myocardial infarction, revascularization, stroke, death), new cases of atrial fibrillation, diabetes mellitus, decreased renal function, and hospitalizations for CHF.</p></sec><sec><title>Results</title><p>Results. The average CHF NYHA class decreased in group 1 from 2.41±0.49 initially to 1.95±0.47 after 24 months (p&lt;0.001), and in group 2 from 2.37±0.49 to 2.19±0.43, respectively (p=0.021; p&lt;0.001 for intergroup differences). The proportion of patients with an increase in distance walked during 6MWT &gt;20% (primary endpoint) in groups 1 and 2 after 24 months was 98.3% (n=58) and 79.7% (n= 46) respectively (p&lt;0.001). Cumulative event-free survival in group 1 was significantly higher than that in group 2 (88.1% versus 66.1%; Chi2 = 7.792, p = 0.005). In group 1, compared with group 2, the chances of combined endpoint development were 4.2 times lower (odds ratio 0.263, 95% confidence interval 0.101-0.683; p=0.006), and failure to achieve the primary endpoint (increased distance walked in 6MCT &gt;20%) — 16.4 times lower (odds ratio 0.061, 95% confidence interval 0.008-0.484; p=0.009).</p></sec><sec><title>Conclusion</title><p>Conclusion. Over the 24-month study period, the effect of EECP in patients with coronary artery disease complicated by CHF demonstrated a stable improvement in exercise tolerance, as well as a decrease in the incidence of adverse clinical outcomes, significantly more pronounced in the group with a large number of EECP procedures</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цель</title><p>Цель. Изучить долгосрочные эффекты комплексной терапии с добавлением усиленной наружной контрпульсацией (УНКП) у пациентов со стабильной ишемической болезнью сердца (ИБС), осложненной хронической сердечной недостаточностью (ХСН).</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В открытом рандомизированном исследовании EXCEL (NCT05913778) 118 пациентов с верифицированной ИБС, осложненной ХСН II-III функционального класса по классификации NYHA со сниженной или промежуточной фракцией выброса левого желудочка рандомизированы в 1-ю группу (n=59) — оптимальная медикаментозная терапия (ОМТ) и УНКП (35 ч, 2 курса в год), 2-ю группу (n=59) — ОМТ и УНКП (35 ч, 1 курс в год). Первичной конечной точкой была доля пациентов с увеличением расстояния, проходимого по данным 6-минутного теста ходьбы, по крайней мере на 20% по сравнению с исходным. Вторичная комбинированная конечная точка включала неблагоприятные сердечно-сосудистые клинические исходы (инфаркт миокарда, реваскуляризация, инсульт, смерть), новые случаи фибрилляции предсердий, сахарного диабета, снижения функции почек, госпитализаций по поводу ХСН.</p></sec><sec><title>Результаты</title><p>Результаты. Доля пациентов с увеличением пройденного расстояния в 6-минутном тесте ходьбы &gt;20% (первичная конечная точка) в 1-й и 2-й группах через 24 мес составила 98,3% (n=58) и 79,7% (n=46) соответственно (p&lt;0,001). Кумулятивная безсобытийная выживаемость в 1-й группе была значимо выше таковой во 2-й группе (88,1% против 66,1%; Chi2 = 7,792, p=0,005). В 1-й группе по сравнению со 2-й шансы развития комбинированной конечной точки оказались ниже в 4,2 раза (отношение шансов 0,263, 95% доверительный интервал 0,101-0,683; p=0,006), а недостижения первичной конечной точки (увеличение проходимой дистанции в 6МХТ &gt;20%) – в 16,4 раза (отношение шансов 0,061, 95% доверительный интервал 0,008-0,484; p=0,009).</p></sec><sec><title>Заключение</title><p>Заключение. За 24-месячный период исследования влияние УНКП у пациентов с ИБС, осложненной ХСН, продемонстрировано стабильное улучшение толерантности к нагрузке, а также снижение частоты возникновения неблагоприятных клинических исходов, значимо более выраженные в группе с большим количеством процедур УНКП.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>усиленная наружная контрпульсация</kwd><kwd>ишемическая болезнь сердца</kwd><kwd>хроническая сердечная недостаточность</kwd><kwd>толерантность к нагрузке</kwd><kwd>выживаемость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>enhanced external counterpulsation</kwd><kwd>coronary artery disease</kwd><kwd>chronic heart failure</kwd><kwd>exercise tolerance</kwd><kwd>survival</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при поддержке Сеченовского Университета.</funding-statement><funding-statement xml:lang="en">The study was supported by Sechenov University.</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">Tsao CW, Aday AW, Almarzooq ZI, et al.; American Heart Association Council on Epidemiology and Prevention Statistics Committee and Stroke Statistics Subcommittee.
