To compare the efficacy of pulmonary vein radiofrequency ablation (RFA) in patients with atrial fibrillation (AF) between two temporal cohorts (2016-2018 and 2021-2022) and to identify factors affecting the likelihood of arrhythmia recurrence.Material and methods. The study sequentially enrolled two patient cohorts. All patients underwent pulmonary vein RFA. The first cohort included 78 patients recruited between 2016 and 2018. The second cohort included 92 patients recruited between 2021 and 2022. The incidence of AF recurrence was assessed at 3, 6, and 9 months post-ablation. All arrhythmia recurrences and complications were confirmed by medical documentation. A range of factors potentially influencing AF recurrence was evaluated, including sex, age, body mass index, AF type, presence of atrial flutter, duration of AF history, echocardiographic parameters, comorbidities, procedural volume and duration, intraoperative electrical cardioversion, and antiarrhythmic drug therapy. Regression analysis with logistic regression equations was used to assess the impact of factors on endpoints. A p-value of 0.05 was adopted as the critical significance level.Results. In the first cohort (2016-2018), the overall RFA efficacy was 65.4%, compared to 83% in the second cohort (2021-2022). Early recurrences were more frequent in the first cohort, while the second cohort exhibited more delayed arrhythmia recurrences. Belonging to the second cohort significantly reduced the risk of atrial fibrillation recurrence (OR 0.46, 95% CI [0.21; 0.97], p=0.04). Conversely, a history of myocardial infarction increased the recurrence risk (OR 12.08, 95% CI [1.46; 251.25], p=0.03). The overall complication rate included four cases of intraoperative hemopericardium and one cardioembolic stroke in the first cohort, and one case each of hemopericardium and cardioembolic stroke in the second cohort. No deaths occurred during the study period.Conclusion. Modern RFA approaches (including earlier application of the procedure and accumulated surgical experience) provide high efficacy in treating atrial fibrillation. A history of myocardial infarction is an independent predictor of recurrence requiring enhanced monitoring. The obtained data confirm the importance of standardizing ablation timing and comprehensive assessment of cardiovascular risk factors.</p></abstract><trans-abstract xml:lang="ru"><p>Цель. Сравнить эффективность радиочастотной абляции (РЧА) устьев легочных вен у пациентов с фибрилляцией предсердий (ФП) в двух временны՚ х когортах (2016-2018 гг. и 2021-2022 гг.) и выявить факторы, влияющие на вероятность развития рецидивов аритмии.Материал и методы. В исследование последовательно включено две когорты пациентов с ФП, которым было проведено оперативное вмешательство в объеме РЧА устьев легочных вен. В первую когорту были включены пациенты в период с 2016-2018 гг. — всего 78 человек, во вторую когорту — 92 пациента в период с 2021 по 2022 гг. Оценивалась частота рецидивов ФП через 3, 6 и 9 мес. после выполненной РЧА, все рецидивы аритмий и осложнения подтверждались медицинской документацией. Оценен ряд факторов, которые способны оказывать влияние на развитие рецидивов ФП: пол, возраст, индекс массы тела, форма аритмии, наличие сопутствующего трепетания предсердий, длительность анамнеза ФП, эхокардиографические параметры, сопутствующие заболевания, объем и время оперативного вмешательства, проведение электрической кардиоверсии интраоперационно, проанализирована антиаритмическая терапия. Для оценки влияния факторов на конечные точки применялся регрессионный анализ с построением уравнений логистической регрессии. В качестве критического уровня значимости принято значение p=0,05.Результаты. В первой когорте (2016-2018 гг.) суммарная эффективность РЧА составила 65,4% vs 83% во второй когорте (2021-2022 гг). В первой когорте чаще возникали рецидивы на ранних сроках наблюдения, во второй когорте чаще наблюдались отсроченные рецидивы аритмий. Принадлежность ко второй когорте статистически значимо снижала риск рецидивов фибрилляции предсердий (отношение шансов (ОШ) 0,46, 95% доверительный интервал (ДИ) [0.21; 0.97], р=0.04), тогда как наличие инфаркта миокарда, увеличивало его (ОШ 12.08, 95% ДИ [146; 251,25], р=0.03). Общая частота осложнений составила четыре случая гемоперикарда интраоперационно, один кардиоэмболический инсульт в первой когорте, один случай гемоперикарда и один случай кардиоэмболического инсульта во второй когорте. Летальных исходов не было.Заключение. Современные подходы к РЧА (включая раннее применение процедуры и накопление хирургического опыта) обеспечивают высокую эффективность в лечении ФП. Перенесенный инфаркт миокарда является независимым предиктором рецидивов ФП, требующим усиленного наблюдения. Полученные данные подтверждают важность стандартизации сроков выполнения абляции и комплексной оценки сердечно-сосудистых факторов риска.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фибрилляция предсердий</kwd><kwd>радиочастотная абляция</kwd><kwd>рецидивы аритмий</kwd><kwd>факторы риска</kwd><kwd>изоляция устьев легочных вен</kwd><kwd>инфаркт миокарда</kwd><kwd>осложнения абляции</kwd><kwd>эффективность радиочастотной абляции</kwd></kwd-group><kwd-group xml:lang="en"><kwd>atrial fibrillation</kwd><kwd>radiofrequency ablation</kwd><kwd>arrhythmia recurrence</kwd><kwd>risk factors</kwd><kwd>pulmonary vein isolation</kwd><kwd>myocardial infarction</kwd><kwd>ablation complications</kwd><kwd>radiofrequency ablation efficacy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проведено при поддержке Первого Московского государственного медицинского университета им.
