To study the relationships between clinical and functional features of chronic obstructive pulmonary disease (COPD) and status of cardiovascular system with focus on identifying factors associated with the atrial fibrillation (AF) in patients with COPD.</p></sec><sec><title>Material and methods</title><p>Material and methods. Patients (n=94) with COPD out of exacerbation and airways obstruction of 2-4 degree (GOLD 2013) were examined. The spirometry, daily pulse oximetry, 24-hour ECG and blood pressure monitoring with vascular wall stiffness estimation, echocardiography were performed. Levels of high-sensitivity C-reactive protein (CRP) werealso assessed.</p></sec><sec><title>Results</title><p>Results. AF paroxysms were found in 46 patients, including newly diagnosed ones in 22 patients. According to the results of multiple correlation analysis, the frequency of AF paroxysms correlated with forced expiratory volume in 1 sec (FEV1) (R=-0.348; p=0.013), minimum oxygen saturation of the blood (min%SpO2) (R=-0.356; p=0.011), CRP level (R=0.442; p=0.001), the sizes of both atria (p&lt;0.001), isovolumic relaxation time (IVRT) of left ventricle (LV) (R=0.350; p=0.022), the right ventricle (RV) size (R=0.478; p&lt;0.001), systolic blood pressure level in the pulmonary artery (PASP) (р&lt;0.001), vascular stiffness - pulse wave velocity in aorta (PWao) (p=0.001). The influence of FEV1 on the left atrium volume index (χ2=7.0; p=0.008) and IVRT LV (χ2=7.9; p=0.005) was revealed. Correlations between min%SpO2 and IVRT and PWao were observed.</p></sec><sec><title>Conclusion</title><p>Conclusion. Severe bronchial obstruction, hypoxemia, systemic inflammation with increase in vascular stiffness (PWao) and myocardium remodeling (increase in the sizes of both atria, PASP, RV size and diastolic dysfunction of LV) are the factors that associated with the occurrence of AF in patients with COPD.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цель</title><p>Цель. Изучение взаимосвязи между клинико-функциональными характеристиками хронической обструктивной болезни легких (ХОБЛ) с различными показателями сердечно-сосудистой системы с выявлением факторов, ассоциированных с фибрилляцией предсердий (ФП).</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Обследовано 94 больных ХОБЛ с обструкцией 2-4 степени (GOLD 2013) вне обострения ХОБЛ. Проводилась спирометрия, суточная пульсоксиметрия, суточное мониторирование ЭКГ (ХМ-ЭКГ) и артериального давления с измерением средней скорости пульсовой волны в аорте (срPWao), эхокардиография, оценивался уровень высокочувствительного С-реактивного белка (вч-СРБ).</p></sec><sec><title>Результаты</title><p>Результаты. У 46 больных были выявлены пароксизмы ФП, в том числе – у 22 пациентов впервые. По результатам множественного корреляционного анализа частота пароксизмов ФП коррелировала с объемом форсированного выдоха за 1 сек (FEV1) (R=-0,348; p=0,013), минимальной сатурацией кислородом крови (мин%SpO2) (R=-0,356; p=0,011), уровнем вч-СРБ (R=0,442; p=0,001), а также размером обоих предсердий (p&lt;0,001), временем изоволюметрического расслабления (IVRT) левого желудочка (ЛЖ) (R=0,350; p=0,022), размером правого желудочка (R=0,478; p&lt;0,001), систолическим давлением в легочной артерии (сДЛА) (p&lt;0,001), срPWao (p=0,001). Выявлено влияние FEV1 на индекс объема левого предсердия (ЛП) (χ2=7,0 p=0,008) и IVRT ЛЖ (χ2=7,9 p=0,005). Наблюдалась взаимосвязь мин%SpO2 с IVRT ЛЖ и cpPWao.</p></sec><sec><title>Заключение</title><p>Заключение. Выраженная бронхообструкция, гипоксемия, системное воспаление c повышением жесткости сосудистой стенки (срPWao) и ремоделированием миокарда (увеличением размеров обоих предсердий, систолического давления в легочной артерии, базального диаметра правого желудочка и диастолической дисфункцией ЛЖ) являются факторами, ассоциированными с ФП у больных ХОБЛ.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>фибрилляция предсердий</kwd><kwd>хроническая обструктивная болезнь легких</kwd><kwd>ремоделирование миокарда</kwd></kwd-group><kwd-group xml:lang="en"><kwd>atrial fibrillation</kwd><kwd>chronic obstructive pulmonary disease</kwd><kwd>myocardial remodeling.</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">Losano R., Naghavi M., Foreman K.
