Оценить влияние динамики массы тела на клиническое течение фибрилляции предсердий у пациентов, страдающих ожирением.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В исследование был включен 101 пациент с пароксизмальной либо персистирующей фибрилляцией предсердий, страдающий первичным ожирением. Дизайн исследования: ретроспективное, одноцентровое, сравнительное исследование. Ретроспективно в зависимости от динамики массы тела пац иенты были разделены на 3 группы: увеличившие на ≥3 % массу тела (группа 1, n=40), сохранившие исходную массу тела ±2,9 % (группа 2, n=29), снизившие на ≥3 % исходную массу тела (группа 3, n=32). Контрольные осмотры врачом проводились не реже 1 раза в 6 месяцев на протяжении не менее 36 месяцев. Изменение формы фибрилляции предсердий регистрировалось на основании клинической картины заболевания и данных холтеровского мониторирования электрокардиограммы в течение 7 дней. Группы были сопоставимы по полу (р=0,9267), возрасту (р=0,3841), росту (р=0,8900), форме заболевания (пароксизмальная фибрилляция предсердий/ персистирующая фибрилляция предсердий) (р=0,8826), выраженности симптомов фибрилляции предсердий по классификации Европейской ассоциации сердечного ритма (р=0,8687) и цифрам систолического артериального давления на начало исследования (р=0,4500).</p></sec><sec><title>Результаты</title><p>Результаты. При заключительном контрольном осмотре масса тела пациентов 1 группы увеличилась в среднем на 11,4 [9,3; 13,1] кг (р(р &lt;0,001*), тогда как пациенты 3 группы продемонстрировали снижение массы тела в среднем на -6,2 [-8,4; -5,3] кг (р &lt;0,001*). Снижение массы тела пациентов 2 группы было незначительным (p=0,5377) и составило -0,1 [-2,0; 1,3] кг. Прогрессирование за­болевания от пароксизмальной формы к персистирующей наблюдалось у 15 (37 %) пациентов 1 группы, у 9 (31 %) пациентов 2 группы и у 2 (6 %) пациентов 3 группы (p=0,0079*). Регресс аритмии от персистирующей формы к пароксизмальной в 1 группе не зарегистрирован (0 %), во 2 группе обратное развитие заболевания отмечено у 1 пациента (3 %) и в 3 группе — у 6 пациентов (19 %) (р=0,0053*). Самопроизвольно­го восстановления синусового ритма у пациентов 1 группы не наблюдалось, во 2 группе оно было отмечено у двух (7 %), а в 3 группе — у 7 (22 %) пациентов (р=0,0047*). Клиническая эффективность катетерной аблации оценивалась после окончания 3-месячного слепого перио­да. Потребность в проведении интервенционных процедур с целью восстановления синусового ритма и их кратность при сравнении групп существенно не отличалась. Однако при попарном сравнении, статистически значимой была разница между 1 и 3 группами участников (р=0,0079* и р=0,0374* соответственно).</p></sec><sec><title> Заключение</title><p> Заключение. Проведенное исследование демонстрирует взаимосвязь между динамикой массы тела и клиническим течением фибрилляции предсердий. Установлено, что прогрессирование ожирения непосредственно ассоциируется с прогрессированием данного типа аритмии. Напротив, снижение массы тела позволяет уменьшить риск усугубления тяжести заболевания, улучшить прогноз и течение фибрилляции предсердий вне зависимости от других значимых факторов риска, повысить эффективность тера­пии антиаритмическими препаратам и результативность интервенционного лечения.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aims</title><p>Aims. To evaluate the impact of body weight dynamics on the clinical course of atrial fibrillation in obese patients.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study included 101 primary obese patients with paroxysmal or persistent atrial fibrillation. Study design: a retrospective, single-center, comparative study. Retrospectively аccording to the he body weight dynamics, patients were divided into 3 groups: those who increased their body weight by &gt;3 % (Group 1, n=40), maintained their initial body weight by ±2.9 % (Group 2, n=29), and reduced their initial body weight by &gt;3 % (Group 3, n=32). Follow-up examinations by a doctor were carried out at least once every 6 months for minimum 36 months. Change in AF type was determined by disease patterns and 7-day Holter monitoring results. The groups were comparable in gender (p=0,9267), age (p=0,3841), height (p=0,8900), and disease form (Paroxysmal atrial fibrillation /Persistent atrial fibrillation) (p=0,8826), the severity of symptoms on the European Heart Rhythm Association score of atrial fibrillations (p=0,8687) and systolic blood pressure at the beginning of the study (p=0,4500).</p></sec><sec><title>Results</title><p>Results. At the final control examination, the body weight of patients in Group 1 increased by an average of 11,4 [9,3; 13,1] kg (р &lt;0,001*), while weight loss in Group 3 averaged -6,2 [-8,4; -5,3] kg (p &lt;0,001*). The decrease in body weight of Group 2 patients was insignificant (p=0,5377) and amounted to -0,1 [-2,0; 1,3] kg. The progression of the disease from paroxysmal to persistent form was observed among 15 (37 %) patients in Group 1, 9 (31 %) patients — in Group 2, 2 (6 %) patients — in Group 3 (p=0,0079*). The regression of arrhythmia from persistent to paroxysmal form was not registered in group 1 (0 %), in group 2, the reverse development of the disease was noted in 1 patient (3 %) and in group 3 — in 6 patients (19 %) (p=0,0053*). There were no free from AF patients in Group 1 at the final follow-up, while 2 (7 %) patients were free from AF in Group 2 and 7 (22 %) — in Group 3 (р=0,0047*). In patients undergoing ablation, procedural success was determined after a 3-month blind period. The need for interventional procedures to restore the sinus rhythm and their multiplicity when comparing the groups did not differ significantly. However, in a pairwise comparison, the difference between groups 1 and 3 of participants was statistically significant (p=0,0079* and p=0,0374*, respectively).</p></sec><sec><title> Conclusion</title><p> Conclusion. This study demonstrates the relationships between the dynamics of body weight and the clinical course of atrial fibrillation. The progression of obesity leads to the progression of the disease. Weight-loss management reverses the type and natural progression of AF, improves the prognosis and the course of disease, regardless of other significant risk factors, increases the anti-arrhythmic therapy effect and the effect of interventional treatment.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>фибрилляция предсердий</kwd><kwd>восстановление синусового ритма</kwd><kwd>ожирение</kwd><kwd>контроль массы тела</kwd><kwd>предсердная кардиомиопатия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>atrial fibrillation</kwd><kwd>sinus rhythm recovery</kwd><kwd>obesity</kwd><kwd>weight control</kwd><kwd>atrial cardiomyopathy</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">Филатов А.Г., Тарашвили Э.Г.
