Изучить факторы, влияющие на возникновение послеоперационной фибрилляции предсердий (ПОФП) у пациентов с хронической ишемической болезнью сердца (ИБС) после аортокоронарного шунтирования (АКШ).</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В одноцентровое проспективное наблюдательное нерандомизированное исследование были включены 152 пациента с хронической ИБС. Средний возраст пациентов составлял 64,4±5,9 года. Все пациенты после АКШ были распределены на 2 группы в зависимости от возникновения фибрилляции предсердий (ФП) в раннем послеоперационном периоде: 1‑я группа с ПОФП (n=43; 28,3 %), 2‑я группа без ПОФП (n=109; 71,7 %). Первичная конечная точка исследования – возникновение впервые возникшей ПОФП в раннем послеоперационном (госпитальном) периоде после АКШ. Вторичная конечная точка исследования – госпитальные послеоперационные осложнения (нефатальный/фатальный острый коронарный синдром – ОКС, нефатальный/фатальный инсульт, «большие» кровотечения, смерть).</p></sec><sec><title>Результаты</title><p>Результаты. Пациенты с ПОФП имели достоверно более выраженные структурно-функциональные изменения сердца, чем лица с сохраненным синусовым ритмом после АКШ: больший объем левого желудочка (ЛЖ), большую массу миокарда ЛЖ, более низкие показатели систолической функции и нарушение диастолической функции ЛЖ, увеличение полости левого предсердия (ЛП). Анализ госпитальных осложнений не выявил различий между группами в зависимости от развития ПОФП. Определены следующие факторы риска ПОФП: возраст старше 65 лет (p=0,022), индекс массы тела ≥30,5 кг/м2 (р=0,020), толщина эпикардиальной жировой ткани &gt;10,5 мм (р=0,015), индексированный объем ЛП &gt;33 мл/м2 (p&lt;0,001), индекс массы миокарда ЛЖ &gt;115 г/м2 (р=0,042), поражение ствола левой коронарной артерии &gt;50 % (p=0,043), продолжительность искусственного кровообращения при АКШ &gt;60 мин (р=0,019), содержание калия в крови в раннем послеоперационном периоде после АКШ (в первые сутки) &lt;3,6 ммоль/л (р&lt;0,001), объем выпота в полости перикарда в раннем послеоперационном периоде &gt;88 мл (р&lt;0,001).</p></sec><sec><title>Заключение</title><p>Заключение. Определение риска развития ПОФП является важным и необходимым для максимального контроля за пациентом с хронической ИБС в послеоперационном периоде.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To study the factors that influence the occurrence of postoperative atrial fibrillation (POAF) in patients with chronic ischemic heart disease (IHD) after coronary artery bypass grafting (CABG).</p></sec><sec><title>Material and methods</title><p>Material and methods. This single-center prospective observational non-randomized study included 152 patients with chronic IHD. Mean age of patients was 64.4±5.9 years. All patients after CABG were divided into two groups based on the occurrence of atrial fibrillation (AF) in the early postoperative period: group 1, with POAF (n=43; 28.3%) and group 2, without POAF (n=109; 71.7%). The primary study endpoint was new-onset POAF in the early postoperative (hospital) period after CABG. The secondary study endpoint was in-hospital postoperative complications (non-fatal/fatal acute coronary syndrome (ACS), non-fatal/fatal stroke, major bleeding, death).</p></sec><sec><title>Results</title><p>Results. Patients with POAF had significantly more pronounced structural and functional changes in the heart than patients with preserved sinus rhythm after CABG: larger left ventricular (LV) volume, greater LV myocardial mass, lower LV systolic function parameters and impaired diastolic function, and an enlarged left atrial (LA) cavity. Analysis of in-hospital complications did not show any differences between the groups associated with the development of POAF. The following risk factors for POAF were identified: age older than 65 years (p=0.022), body mass index ≥30.5 kg/m2 (p=0.020), epicardial adipose tissue thickness &gt;10.5 mm (p=0.015), indexed LA volume &gt;33 ml/m2 (p&lt;0.001), LV myocardial mass index &gt;115 g/m2 (p=0.042), left main coronary artery disease &gt;50% (p=0.043), duration of cardiopulmonary bypass during CABG &gt;60 min (p=0.019), blood potassium concentration in the early postoperative period after CABG (on the first day) &lt;3.6 mmol/l (p&lt;0.001), and pericardial effusion volume in the early postoperative period &gt;88 ml (p&lt;0.001).</p></sec><sec><title>Conclusion</title><p>Conclusion. Determining the risk of developing POAF is important and necessary for the closest monitoring of a patient with chronic IHD in the postoperative period.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Хроническая ишемическая болезнь сердца</kwd><kwd>аортокоронарное шунтирование</kwd><kwd>послеоперационная фибрилляция предсердий</kwd><kwd>предикторы фибрилляции предсердий</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Chronic ischemic heart disease</kwd><kwd>coronary artery bypass grafting</kwd><kwd>postoperative atrial fibrillation</kwd><kwd>predictors of atrial fibrillation</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Источники финансирования отсутствуют.
