Оценивалась кли‑ ническая значимость применения фармакогенетического подхода при  анализе индивидуальных сроков достижения и  вре‑ мени нахождения в терапевтическом диапазоне международного нормализованного отношения (МНО). Цель исследования. Определение клинической эффективности фармакогенетического подхода в начале терапии варфарином у больных с проте‑ зами клапанов сердца. Материалы и методы. Обследовано 915 пациентов, из них 512 женщин и 403 мужчины (средний воз‑ раст 56±10 лет), проживающих на территории Западной Сибири. Основным диагнозом, ставшим причиной приобретенно‑ го порока, явилась ревматическая болезнь сердца. В 70% случаев для коррекции порока сердца проводилось протезирование механическими клапанами. Молекулярно-генетическое тестирование осуществляли методом полимеразной цепной реакции в  режиме реального времени. Результаты. Частоты аллелей и  генотипов CYP2C9 и  VKORC1 в  обследованной популяции пациентов с  протезами клапанов сердца не  отличались от их  распределения в  популяциях европеоидного происхождения. Применение в начале терапии варфарином результатов фармакогентического тестирования в 2 раза уменьшило сроки подбора терапевтической дозы антикоагулянта и увеличило на 20,2% длительность нахождения в терапевтическом диапазоне МНО. Заключение. Применение фармакогенетического подхода в начале терапии варфарином у данной категории больных способ‑ ствует повышаю эффективности и безопасности антикоагулянтной терапии.</p></abstract><trans-abstract xml:lang="en"><p>Background. This study examined clinical, demographic, anthropometric, and inheritance factors that influence individual sensitivity to warfarin therapy after heart valve surgery. The clinical significance of the pharmacogenetic approach was assessed using the individual time frame and time spent in the INR therapeutic range. Aims. We determined the clinical outcome of the pharmacogenetic approach at the start of warfarin therapy in patients with prosthetic heart valves. Materials and methods. The study included 915 patients, of which 512 women and 403 men (mean age 56±10 years), living in Western Siberia. Rheumatic heart disease was the main diagnosis that caused the acquired defect. Mechanical prostheses were used in 70% of cases of cardiac surgery. Real-time polymerase chain reaction used for molecular genetic testing. Results. The frequencies of the alleles and genotypes of CYP2C9 and VKORC1 in the study population of patients with heart valves prosthetic correspond to the distribution in Caucasoid populations. The use of pharmacogenetic testing results at the beginning of warfarin therapy reduced the time required for selecting a therapeutic dose of anticoagulant by 2 times and increased the duration of stay in the INR therapeutic range by 20.2%. Conclusion. The use of the pharmacogenetic approach at the begin‑ ning of warfarin therapy contributes to the effectiveness and safety of anticoagulant therapy in this category of patients.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фармакогенетическое тестирование чувствительности к варфарину</kwd><kwd>протезированные клапаны сердца</kwd><kwd>эффективность и безопасность антикоагулянтной терапии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pharmacogenetic testing of sensitivity to warfarin</kwd><kwd>heart valves prosthetic</kwd><kwd>efficacy and safety of anticoagulant therapy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы заявляют об отсутствии конфликта интересов.</funding-statement><funding-statement xml:lang="en">Авторы заявляют от отсутствии конфликта интересов</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Горбунова Е.В., Одаренко Ю.Н., Мамчур С.Е., Кудрявцева Н.Г., Салахов Р.Р.
