Было показано, что перевод с одного прямого орального антикоагулянта (ПОАК) на другой (с иным механизмом действия), а также с ПОАК на варфарин может изменить состояние свертывающей системы плазмы крови в сторону как гипер-, так и гипокоагуляции. В отличие от стандартных тестов гемостаза тест ТД может применяться для оценки протромботического статуса пациента с ФП и персонифицированного подбора эффективной антикоагулянтной терапии.</p></abstract><trans-abstract xml:lang="en"><p>Clinical observations of the possibility of using the thrombodynamics test (TD) in comparison with standard hemostasis tests in patients with non-valvular atrial fibrillation (AF) and detected thrombosis of the left atrial appendage against the background constant oral anticoagulants are presented. It has been shown that the transfer from one direct oral anticoagulant (DOACs) to another (with a different mechanism of action), as well as from DOACs to warfarin, can change the state of the blood plasma coagulation system towards both hyper- and hypocoagulation. Unlike standard hemostasis tests, TD can be used to assess the prothrombotic status of a patient with AF and personalized selection of effective anticoagulant therapy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фибрилляция предсердий</kwd><kwd>тромбоз ушка левого предсердия</kwd><kwd>оральные антикоагулянты</kwd><kwd>тест тромбодинамики</kwd></kwd-group><kwd-group xml:lang="en"><kwd>atrial fibrillation</kwd><kwd>thrombosis of the left atrial appendage</kwd><kwd>oral anticoagulants</kwd><kwd>thrombodynamics test</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).
