Изучить возможности прогнозирования тромбоза левого предсердия и/или его ушка (ЛП/уЛП) перед катетерной аблацией (КА) или плановой кардиоверсией (КВ) у больных с неклапанной фибрилляцией предсердий (нФП) или трепетанием предсердий (ТП) с использованием показателей, легко доступных в повседневной врачебной практике.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В одноцентровом ретроспективном исследовании проанализированы истории болезни 1994 пациентов с нФП или ТП за период 2014-2019гг, которым перед КА или плановой КВ была выполнена чреспищеводная эхокардиография. Тромб в ЛП/уЛП был обнаружен у 33 (1,6%) больных. Для группы сравнения случайным образом были отобраны 167 пациентов без тромбоза ЛП/уЛП. Среди возможных предикторов тромбоза ЛП/уЛП оценивались демографические, анамнестические, клинические, лабораторные данные, результаты трансторакальной эхокардиографии, а также шкала оценки риска тромбоза ЛП/уЛП — СHA2DS2-VASc-RAF (CHA2DS2-VASc плюс 2 балла при расчетной скорости клубочковой фильтрации &lt;56 мл/мин/1,73 м2, 4 балла при персистирующей форме ФП (продолжительностью &gt;7 дней), 10 баллов при постоянной форме ФП).</p></sec><sec><title>Результаты</title><p>Результаты. Средний возраст больных составил 60,3±10,9 лет, 55% мужчин. Преобладали больные с нФП (87,5%), госпитализированные для КА (84,0%). По результатам многофакторного анализа с выявлением тромба в ЛП/уЛП ассоциировались тяжесть симптомов, связанных с аритмией (отношение шансов (ОШ) для 3-4 функциональных классов по модифицированной шкале EHRA (European Heart Rhythm Association) 14,29 при 95% границах доверительного интервала (ДИ): 3,3-61,8; р&lt;0,0001), фракция выброса левого желудочка &lt;48% (ОШ 7,83 при 95% ДИ: 1,2-53,05; р=0,035) и сумма баллов по шкале СHA2DS2-VASc-RAF (ОШ 1,29 при 95% ДИ: 1,08-1,5; р=0,004). Дополнение шкалы СHA2DS2-VASc-RAF новыми независимыми предикторами тромбоза ЛП/уЛП не привело к статически значимому увеличению площади под характеристической кривой, которая составляла 0,83 (95% ДИ: 0,76-0,91) и 0,87 (95% ДИ: 0,80-0,94), соответственно (р=0,13). ОШ тромбоза ЛП/уЛП при сумме баллов по шкале СHA2DS2-VASc-RAF &gt;3 составляло 12,8 (95% ДИ: 3,8-43,9; p&lt;0,0001), чувствительность, специфичность, предсказательная ценность положительного и отрицательного результатов — 90,6, 57,1, 30,2 и 96,7%, соответственно. ОШ тромбоза ЛП/уЛП при сумме баллов по модифицированной шкале СHA2DS2-VASc-RAF &gt;8 составила 25,8 (95% ДИ: 5,9-112,3; р&lt;0,0001), чувствительность, специфичность, предсказательная ценность положительного и отрицательного результатов — 93,5, 64,0, 34,9 и 97,9%, соответственно.</p></sec><sec><title>Заключение</title><p>Заключение. При прогнозировании тромбоза ЛП/уЛП, выявляемого при чреспищеводной эхокардиографии перед КА или плановой КВ у больных с нФП или ТП, не имевших выраженной структурной патологии сердца и тяжелых сопутствующих заболеваний, учет выраженности симптомов, связанных с аритмией и сниженной фракции выброса левого желудочка (&lt;48%) в дополнение к шкале стратификации риска тромбоза ЛП/уЛП CHA2DS2-VASc-RAF не привел к увеличению площади под характеристической кривой, но позволил увеличить ОШ выявления тромбоза ЛП/уЛП в 2 раза и повысить чувствительность, специфичность, предсказующую ценность положительного и отрицательного результатов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To study the potential of predicting thrombosis of the left atrium (LA) and/or LA appendage (LAA) before catheter ablation (CA) or elective cardioversion in patients with nonvalvular atrial fibrillation (NAF) or atrial flutter (AFL) using indicators available in routine practice.</p></sec><sec><title>Material and methods</title><p>Material and methods. In this single-center retrospective study, the medical records of 1994 patients with nAF or AFL for the period 2014-2019 were analyzed, who underwent transesophageal echocardiography before CA or elective CV. LA/LAA thrombus was found in 33 (1,6%) patients. For the comparison group, 167 patients were randomly selected without LA/LAA thrombosis. Demographic, anamnestic, clinical, laboratory data, results of transthoracic echocardiography, as well as the CHA2DS2-VASc-RAF (CHA2DS2-VASc plus 2 points for an estimated glomerular filtration rate &lt;56 ml/min/1,73 m2, 4 points for persistent AF (lasting &gt;7 days), 10 points for persistent AF).</p></sec><sec><title>Results</title><p>Results. The mean age of the patients was 60,3±10,9 years (men, 55%). There were more patients with NAF (87,5%), hospitalized for CV (84,0%). Multivariate analysis revealed that the severity of symptoms associated with arrhythmia was associated with the detection of a LA/LAA thrombus (odds ratio (OR) for EHRA class 3-4 14,29 at 95% confidence interval (CI): 3,3-61,8; p&lt;0,0001), left ventricular ejection fraction &lt;48% (OR, 7,83; 95% CI: 1,2-53,05; p=0,035) and total CHA2DS2-VASc-RAF score (OR, 1,29 at 95% CI: 1,08-1,5; p=0,004). Sup­ple­mentation of the CHA2DS2-VASc-RAF with new independent predictors of LA/LAA thrombosis did not lead to a significant increase in the area under the characteristic curve, which was 0,83 (95% CI: 0,76-0,91) and 0,87 (95% CI: 0,80-0,94), respectively (p=0,13). The OR of LA/LAA thrombosis with a total score CHA2DS2-VASc-RAF &gt;3 was 12,8 (95% CI: 3,8-43,9; p&lt;0,0001), while the sensitivity, specificity, positive and negative predictive value — 90,6, 57,1, 30,2 and 96,7% respectively. The OR of thrombosis of LA/LAA with a CHA2DS2-VASc-RAF score &gt;8 was 25,8 (95% CI: 5,9-112,3; p&lt;0,0001), while sensitivity, specificity, positive and negative predictive value — 93,5, 64,0, 34,9 and 97,9%, respectively.</p></sec><sec><title>Conclusion</title><p>Conclusion. When predicting LA/LAA thrombosis, detected during transesophageal echocardiography before CA or elective CV in patients with NAF or AFL who did not have a pronounced structural heart pathology and severe concomitant diseases, taking into account the severity of symptoms associated with arrhythmia and a reduced left ventricular ejection fraction (&lt;48%) in addition to the risk stratification scale for LA/LAA thrombosis CHA2DS2-VASc-RAF did not lead to an increase in the area under the characteristic curve, but made it possible to increase the OR of LA/LAA thrombosis detection by 2 times and increase the sensitivity, specificity, positive and negative predictive value.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>фибрилляция предсердий</kwd><kwd>неклапанная фибрилляция предсердий</kwd><kwd>тромбоз левого предсердия</kwd><kwd>тромбоз ушка левого предсердия</kwd><kwd>шкала оценки риска</kwd><kwd>СHA2DS2-VASc-RAF</kwd><kwd>катетерная аблация</kwd><kwd>кардиоверсия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>atrial fibrillation</kwd><kwd>nonvalvular atrial fibrillation</kwd><kwd>left atrial thrombosis</kwd><kwd>left atrial appendage thrombosis</kwd><kwd>risk score</kwd><kwd>СHA2DS2-VASc-RAF</kwd><kwd>catheter ablation</kwd><kwd>cardioversion</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">Hindricks G, Potpara T, Dagres N, et al. 2020 ESC Guidelines for the diagnosis and management of atrial fibrillation developed in collaboration with the European Association for Cardio-Thoracic Surgery (EACTS): The Task Force for the diagnosis and management of atrial fibrillation of the European Society of Cardiology (ESC) Developed with the special contribution of the European Heart Rhythm Association (EHRA) of the ESC.
