Depending on the type of anticoagulant taken, the patients were divided into 2 groups: the first group included 253 (78.6%) people who took warfarin, the second group – 69 (21.4%) people, who were prescribed a new oral anticoagulant – rivaroxaban.</p> <p><bold>Results.</bold> By the end of the one-year follow-up from the start of anticoagulant treatment, only 8.7% of patients in the first group followed the doctor's prescription; the second group had 59.4% of adherent patients. The vast majority of patients refused warfarin therapy due to the inability to control INR. In the case of the appointment of rivaroxaban, the reason for the refusal to take was the high cost of the drugs.</p> <p><bold>Conclusion.</bold> Effective prevention of thromboembolic complications in atrial fibrillation requires the development of appropriate measures to improve adherence to treatment.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель</bold> – оценить приверженности пациентов пожилого возраста с фибрилляцией предсердий неклапанной этиологии, которые находились на антикоагулянтной терапии антагонистами витамина К – варфарином и новым оральным антикоагулянтом – ривароксабаном.</p> <p><bold>Материал и методы.</bold> В ходе исследования провели наблюдение за 322 пациентами с фибрилляцией предсердий неклапапнной этиологии. В зависимости от принимаемого вида антикоагулянта пациенты были разделены на 2 группы: первую группу составили 253 (78,6%) чел., которые принимали варфарин; вторую группу – 69 (21,4%) чел., которым был назначен новый оральный антикоагулянт – ривароксабан.</p> <p><bold>Результаты. </bold>К концу года наблюдения от начала терапии антикоагулянтами предписание врача в первой группе выдержали только 8,7% пациентов, во второй группе – 59,4%. Причиной отказа от приема варфарина в подавляющем большинстве случаев стала невозможность контроля МНО, а в случае назначения ривароксабана – высокая стоимость препарата.</p> <p><bold>Выводы.</bold> Для эффективной профилактики тромбоэмболических осложнений при фибрилляции предсердий необходимы разработки соответствующих мер для улучшения приверженности к лечению.</p></trans-abstract><kwd-group xml:lang="en"><kwd>geriatrics</kwd><kwd>elderly people</kwd><kwd>atrial fibrillation</kwd><kwd>anticoagulant therapy</kwd><kwd>warfarin</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>гериатрия</kwd><kwd>пожилые люди</kwd><kwd>фибрилляция предсердий</kwd><kwd>антикоагулянтная терапия</kwd><kwd>варфарин</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>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 of Cardio-Thoracic Surgery (EACTS).
