Цель исследования – изучить эффективность и безопасность сниженной дозы прямых пероральных антикоагулянтов (ППАКГ) в составе тройной антитромботической терапии у больных фибрилляцией предсердий (ФП), перенесших плановое чрескожное коронарное вмешательство (ЧКВ), а также выявить факторы, ассоциированные с выбором такой стратегии. Материалы и методы. Исследование представляет собой анализ когорты больных ФП, которым успешно выполнено плановое ЧКВ и назначены ППАКГ в составе тройной антитромботической терапии (ТАТ). Влияние приема сниженной дозы ППАКГ в составе ТАТ на частоту комбинированной конечной точки эффективности (острый коронарный синдром, ишемический инсульт, венозные тромбоэмболические осложнения, сердечно-сосудистая смерть и усугубление клиники стенокардии/потребность в проведении не запланированного ЧКВ), а также конечной точки безопасности (геморрагические осложнения BARC 2–5) оценивали с помощью критерия Log-Rank. Результаты. Всего в исследование включено 124 пациента (69,4% женщины, средний возраст 69,9±8,2 года). Медиана суммы баллов по шкале CHA2DS2-VASc составила 5, медиана индекса Charlson – 7. Половине (52%) из включенных в исследование пациентов лечащие врачи назначали ППАКГ в сниженных дозах. По результатам множественной регрессии сумма баллов по шкале CHA2DS2-VASc ≥5 оказалась независимым предиктором назначения сниженной дозы ППАКГ больным ФП, нуждавшимся в приеме ТАТ (β=0,32, p=0,0328). Медиана длительности наблюдения составила 11 мес. За этот период зарегистрировано 17 неблагоприятных тромботических событий, кровотечения BARC 2–5 возникли у 27 пациентов. В группе больных, получавших ППАКГ в сниженной дозе, доля пациентов без тромботических осложнений была достоверно выше, чем в группе полной дозы ППАКГ (0,79 против 0,93, Log-Rank p= 0,0292). Частота кровотечений BARC 2–5 у пациентов, получавших полную и сниженную дозы ППАКГ в составе ТАТ, достоверно не различалась (0,78 против 0,75, Log-Rank p=0,06742). Заключение. Назначение сниженной дозы ППАКГ в составе ТАТ у больных ФП, подвергнутых ЧКВ, ассоциировалось с достоверным увеличением частоты всех тромботических событий по сравнению с пациентами, получавшими полную дозу антикоагулянтов, при сопоставимом числе геморрагических осложнений.
Aim. To evaluate efficacy and safety of reduced dose of direct oral anticoagulants (DOACs) as part of triple antithrombotic therapy in AF patients, undergoing elective percutaneous coronary intervention (PCI), and to identify factors, associated with this strategy. Materials and methods. The study is a cohort analysis of AF patients with AF, who successfully underwent elective PCI and assigned DOACs as part of triple antithrombotic therapy (TAT).Influence of a reduced DOACs dose as a part of TAT on the frequency of thecomposite efficacy endpoint (acute coronary syndrome, ischemic stroke, venous thromboembolic events, cardiovascular death and angina pectoris aggravation/need for unplanned PCI) and safety endpoint (hemorrhagic complications BARC types 2–5) were assessed using the Log-Rank criterion. Results. The study included 124 pts (69.4% women, mean aged 69±8.2 years). Themedian total score CHA2DS2-VASc was 5, the median of the Charlson index composed 7. Half (52%) of AF patients with high risk of thrombotic events after elective PCI received reduced-DOACs dose. Median follow up period was 11.0 month. 17 adverse thrombotic events were recorded during this period, BARC 2–5 bleedings occurred in 27 patients. Reduced DOACs doses in AF patients undergoing PCI were associated with significant increase of thrombotic events during follow up period compared to patients received full DOACs doses (0.79 vs 0.93, Log-Rank p=0.0292). Patients, who received full and reduced DOAC doses, were comparable in the frequency of BARC 2–5 bleedings (0.78 vs 0.75, Log-Rank p=0.06742). Conclusions. The administration of a reduced DOACs dose as a part of TAT in patients with AF, who underwent PCI, was associated with significant increase in the incidence of all thrombotic events, compared to patients, who received full dose of anticoagulants. The number of hemorrhagic complications was comparable.
Keywords: direct oral anticoagulants, triple antithrombotic therapy, atrial fibrillation, percutaneous coronary interventions, risk of cardiovascular complications.
