В исследование были включены 282 пациента, которым выполнялось стентирование незащищенного ствола ЛКА. Средняя продолжительность наблюдения составила 34,6 [33,9; 35,3] мес. Пациенты были разделены на три группы в зависимости от типа имплантируемого стента (I, II и III поколения соответственно).</p></sec><sec><title>Результаты</title><p>Результаты. Частота неблагоприятных сердечно-сосудистых событий у пациентов 1-й группы достоверно выше по сравнению с пациентами 2-й и 3-й групп (29 и 7,6%, р&lt;0,0001). Частота тромбозов стентов I поколения достоверно выше (7,0%) по сравнению с таковой у стентов II и III поколения (1,6%) (р=0,02). Частота неблагоприятных сердечно-сосудистых событий сопоставима между 2-й и 3-й группами, несмотря на сокращенную длительность двойной антиагрегантной терапии в группе стентов III поколения. Отсутствие постдилатации стентов в стволе ЛКА является независимым фактором риска неблагоприятного прогноза.</p></sec><sec><title>Заключение</title><p>Заключение. Использование стентов II и III поколения наряду с изменением технических аспектов стентирования незащищенного ствола ЛКА приводит к существенному снижению риска неблагоприятных сердечно-сосудистых событий и позволяет расширить показания к вмешательству у данной категории пациентов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective. To assess the immediate and long-term results of stenting of the unprotected left coronary artery (LCA) trunk in patients, by using different types of drug-eluting stents.</p></sec><sec><title>Material and methods</title><p>Material and methods. The follow-up covered 282 patients who had undergone stenting of the unprotected LCA trunk. The mean follow-up was 34.6 [33.9; 35.3] months. The patients were divided into groups according to the type of a first-, second-, and third-generation implanted stent.</p></sec><sec><title>Results</title><p>Results. The incidence of adverse cardiovascular events in the patients of Group 1 was significantly higher than in those in Groups 2 and 3 (29 and 7.6%, p&lt;0.0001). The incidence of thrombosis of first-generation stents (7.0%) was significantly higher than that of second- and third-generation ones (1.6%) (p=0.02). The incidence of adverse cardiovascular events was comparable between Groups 2 and 3, despite a shorter duration of dual antiplatelet therapy in the third-generation stent group. The absence of stent postdilatation in the LCA trunk is an independent risk factor for adverse prognosis.</p></sec><sec><title>Conclusion</title><p>Conclusion. The use of second- and third-generation stents along with changes in the technical aspects of stenting of the unprotected LCA trunk leads to a substantial reduction in the risk of adverse cardiovascular events and allows the indications for intervention to be expanded in this patient category.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>стентирование ствола левой коронарной артерии</kwd><kwd>ишемическая болезнь сердца</kwd><kwd>стенты с биорастворимым полимерным покрытием</kwd><kwd>сокращенная длительность двойной антиагрегантной терапии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>stenting of the left main coronary artery</kwd><kwd>coronary heart disease</kwd><kwd>stents with biodegradable polymeric coating</kwd><kwd>reduced duration of dual antiplatelet 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">Арутюнян Г.К., Терещенко А.С., Кайралиев Д.М., Меркулов Е.В., Проваторов С.И., Самко А.Н.
