</italic></bold><italic>Worldwide, research continues into various factors that may influence the success of catheter treatment of atrial fibrillation. In this regard, the influence of the state of the sympathoadrenal system of the body has not been studied enough. <bold>Aims</bold> — to evaluate the effectiveness of interventional treatment of atrial fibrillation (AF) in patients with and without myocarditis, depending on the level of beta-adrenergic responsiveness of the organism.<bold> Materials and methods.</bold> The study sample included 40 patients. Of these, 27 (67.5%) are men. The age in the sample was 49 (44; 55) years. The study included 25 (62.5%) patients with paroxysmal AF, 10 (25.0%) with persistent and 5 (12.5%) with long-term persistent. All patients underwent surgical treatment of AF using radiofrequency (RFA) or cryoablation (CBA). Endomyocardial biopsy was performed in 18 patients to verify the diagnosis. Beta-adrenergic responsiveness (beta-ARM) was assessed in dynamics 3 days after surgery, 3 months and 12 months. The follow-up period for patients was 12 months.<bold> Results.</bold> All patients underwent surgical treatment of AF, in 7 cases (17.5%) CBA of the pulmonary veins was performed, in 33 (82.5%) cases RFA was performed. According to the biopsy results, signs of myocarditis were detected in 9 patients (22.5%). Focal myocarditis was found in 7 patients, diffuse — in 2. The effectiveness of catheter treatment in general was 72.5%, for CBA — 71.5%, for RFA — 73.5%. Beta-ARM before ablation was 19.16% [12.46; 27.46], 3 days after ablation — 24.43% [15.38; 33.65], after 3 months was 20.27% [9.90; 27.71], in 4 patients after 12 months, beta-ARM was 32.5% [20.0; 43.2]. The dynamics and influence of beta-ARM on the effectiveness of interventional treatment of AF in patients with early and late relapses, the presence of myocarditis was assessed. <bold>Conclusions. </bold>The results obtained showed no effect of the level of beta-ARM on the effectiveness of RFA and CBA in patients with and without myocarditis. Beta-ARM showed no association with the development of early arrhythmia recurrences after ablation. No statistically significant differences were found when comparing beta-ARM levels in patients with and without diagnosed myocarditis.</italic></p></abstract><trans-abstract xml:lang="ru"><p><bold><italic>Обоснование. </italic></bold><italic>Во всем мире продолжается изучение различных факторов, которые могут влиять на успех катетерного лечения фибрилляции предсердий (ФП). В этом отношении влияние состояния симпатоадреналовой системы организма изучено недостаточно. <bold>Цель исследования</bold> — оценка эффективности интервенционного лечения ФП у пациентов с миокардитом и без него в зависимости от уровня бета-адренореактивности организма. <bold>Методы.</bold> В исследуемую выборку включены 40 пациентов. Из них 27 (67,5%) — мужчины. Возраст в выборке составил 49 (44; 55) лет. В исследование вошли 25 (62,5%) больных с пароксизмальной формой ФП, 10 (25,0%) — с персистирующей и 5 (12,5%) — с длительно-персистирующей. Всем пациентам было проведено оперативное лечение ФП методом радиочастотной (РЧА) или криоаблации (КБА). Для верификации диагноза у 18 больных выполняли эндомиокардиальную биопсию. Проведена оценка бета-адренореактивности мембран эритроцитов (бета-АРМ) в динамике до операции, через 3 дня после операции, 3 мес и 12 мес. Период наблюдения за пациентами составил 12 мес. <bold>Результаты.</bold> Всем пациентам проведено оперативное лечение ФП, в 7 случаях (17,5%) выполнена КБА легочных вен, в 33 (82,5%) — РЧА. По результатам биопсии признаки миокардита выявлены у 9 больных (22,5%). Очаговый миокардит обнаружен у 7 больных, диффузный — у 2. Эффективность катетерного лечения в общем составила 72,5%, для КБА — 71,5%, для РЧА — 73,5%. Бета-АРМ до аблации составила 19,16% [12,46; 27,46], через 3 сут после аблации — 24,43% [15,38; 33,65], через 3 мес составила 20,27% [9,90; 27,71], у 4 пациентов через 12 мес бета-АРМ наблюдалась 32,5% [20,0; 43,2]. Оценены динамика и влияние бета-АРМ на эффективность интервенционного лечения ФП у больных с ранними и поздними рецидивами, наличием миокардита. <bold>Заключение. </bold>Полученные результаты показали отсутствие влияния уровня бета-АРМ на эффективность РЧА и КБА у пациентов с миокардитом и без него. Бета-АРМ не показала связи с развитием ранних рецидивов аритмии после аблации. Не обнаружено статистически значимых различий при сравнении показателей уровня бета-АРМ у пациентов с выявленным миокардитом и без него.</italic></p></trans-abstract><kwd-group xml:lang="en"><kwd>atrial fibrillation</kwd><kwd>myocarditis</kwd><kwd>membrane beta-adrenergic reactivity</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>фибрилляция предсердий</kwd><kwd>миокардит</kwd><kwd>бета-адренореактивность мембран</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Правительство Российской Федерации</institution></institution-wrap><institution-wrap><institution xml:lang="en">Government of the Russian Federation</institution></institution-wrap></funding-source><award-id>122020300183-4</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Киргизова М.А., Баталов Р.Е., Татарский Б.А., Попов С.В.
