Оценить частоту выявления умеренной систолической дисфункции у больных стабильной ишемической болезнью сердца (ИБС) и изучить факторы, ассоциированные с ее наличием.Материалы и методы. В исследование включены данные 200 больных ИБС, госпитализированных в кардиологическое отделение НИИ КПССЗ для подготовки к операции коронарного шунтирования. Предоперационное обследование выполнялись в рамках поискового научного исследования №15/2017-2019. Группирующим признаком являлось наличие или отсутствие систолической дисфункции правого желудочка (СДПЖ). Группа I представлена пациентами с СДПЖ (n = 30, 64 [59; 68] лет), группа II – пациентами без СДПЖ (n = 170, 64 [60; 68] лет).Результаты. По результатам однофакторного логистического регрессионного анализа были выделены факторы, ассоциированные с наличием СДПЖ: наличие в анамнезе инфаркта миокарда (р = 0,098), хронической сердечной недостаточности (р = 0,020), увеличение стажа курения (р = 0,003), конечного систолического и диастолического объемов левого желудочка (р = 0,005 и р = 0,004), снижение систолической экскурсии фиброзного кольца трикуспидального клапана (р&lt;0,001), скорости распространения раннего митрального потока (р = 0,027) и фракции выброса левого желудочка (ФВ ЛЖ) (р = 0,002), наличие значимых стенозов огибающей артерии (р = 0,075), окклюзии правой коронарной артерии (КА) (р = 0,073), однососудистого и трехсосудистого поражения КА (р = 0,055 и р = 0,014). Многофакторный анализ представлен тремя моделями, согласно которым, независимыми предикторами наличия СДПЖ являлось снижение ФВ ЛЖ (р = 0,009) и в некоторой степени – трехсосудистое поражение КА (р = 0,055) и снижение скорости распространения раннего митрального потока (р = 0,072).Заключение. Умеренная СДПЖ выявлена у 15% больных стабильной ИБС с сохранённой функцией левого желудочка. Факторами, независимо ассоциированными с наличием СДПЖ, были снижение ФВ ЛЖ, но не поражение отдельных КА, число поражённых КА, наличие и локализация перенесенного инфаркта миокарда.</p></abstract><trans-abstract xml:lang="en"><p>Aim. To assess the incidence of moderate systolic dysfunction in patients with stable coronary artery disease and determine the factors associated with it.Methods. 200 patients with coronary artery disease admitted to the Cardiology Department of the Research Institute for coronary artery bypass grafting were included in the study. Patients were assigned to two groups depending on the presence or absence of right ventricular systolic dysfunction (RVSD). Patients with RVSD (n = 30, 64 [59; 68] years), were assigned in Group 1, whereas patients without it (n = 170, 64 [60; 68] years) were assigned to Group 2.Results. Univariate logistic regression reported the following factors to be associated with RVSD: prior myocardial infarction (p = 0.098), chronic heart failure (p = 0.020), long smoking history (p = 0.003), increased left ventricular end-systolic and enddiastolic volumes (p = 0.005 and p = 0.004), decreased tricuspid annular plane systolic excursion (p &lt;0.001), decreased early mitral flow propagation velocity (p = 0.027) and left ventricular ejection fraction (p = 0.002), significant circumflex artery stenosis (p = 0.075), right coronary artery occlusion (p = 0.073), singlevessel and three-vessel coronary artery disease (p = 0.055 and p = 0.014). Three multivariate models were generated. A decrease in the left ventricular ejection fraction (p = 0.009), three-vessel coronary artery disease (p = 0.055), and early mitral flow propagation velocity (p = 0.072) were considered as independent predictors of RVSD.Conclusion. Moderate RVSD was found in 15% of patients with stable coronary artery disease and preserved left ventricular function. A decrease in the left ventricular ejection fraction, but not damage to individual coronary arteries, the number of affected coronary arteries, the presence and localization of myocardial infarction were among the factors independently associated with right ventricular systolic function.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>систолическая дисфункция</kwd><kwd>правый желудочек</kwd><kwd>хронический коронарный синдром</kwd></kwd-group><kwd-group xml:lang="en"><kwd>systolic dysfunction</kwd><kwd>right ventricle</kwd><kwd>chronic coronary syndrome</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследование выполнено при финансовой поддержке Министерства науки и высшего образования РФ в рамках поисковых научных исследований «Оценка диастолической функции левого и правого желудочка в прогнозировании исходов коронарного шунтирования» на базе Федерального государственного бюджетного научного учреждения «Научно-исследовательского института комплексных проблем сердечно-сосудистых заболеваний».</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">Smarz K, Zaborska B, Jaxa-Chamiec T, Tysarowski M, Budaj A.
