The role of the NO metabolic pathway in the development of pulmonary arterial hypertension (PAH) was shown. From the standpoint of pathogenesis, the importance of the effect of medication on this pathway through soluble guanylate cyclase (sGC) has been assessed. The effects of the drug riociguat, the only member of the sGC stimulant class approved for the treatment of PAH, are associated with a dual mechanism of action: riociguat sensitizes the sGC enzyme to endogenous NO by stabilizing the NO-sGC bond, and also directly stimulates the latter through another site of the bond, regardless of NO. The favorable efficacy and safety profile of riociguat has been demonstrated in the PATENT-1,2 studies. During therapy, patients showed an improvement in exercise tolerance, functional class, and a number of other indicators. Studies that indicate the feasibility of using a change in therapy in clinical practice are reviewed. In particular, the article provides a detailed analysis of the REPLACE study. It demonstrated a significantly greater likelihood of achieving clinical improvement and a significant decrease in the rate of development of clinical deterioration when switching patients with PAH from PDE-5 inhibitors to riociguat. This therapy was well tolerated and can be considered as a strategy for managing patients at intermediate risk with insufficient patient response to PDE-5 inhibitors. In conclusion, the need to plan the need for specific therapy for pulmonary arterial hypertension in the region is noted in order to rapidly escalate therapy to achieve a low risk of mortality in these patients.</p></abstract><trans-abstract xml:lang="ru"><p>Статья посвящена актуальным вопросам ведения пациентов с легочной артериальной гипертензией и стратегии переключения на терапию риоцигуатом у пациентов с недостаточным клиническим ответом на фоне ингибиторов фосфодиэстеразы типа 5 (ФДЭ-5). Показана роль метаболического пути NO в развитии легочной артериальной гипертензии (ЛАГ). С позиций патогенеза оценена важность медикаментозного воздействия на этот путь через растворимую гуанилатциклазу (рГЦ). Эффекты препарата риоцигуат, единственного представителя класса стимуляторов рГЦ, одобренного для лечения ЛАГ, связаны c двойным механизмом действия: риоцигуат сенсибилизирует фермент рГЦ к эндогенному NO путем стабилизации связи NO-рГЦ, а также напрямую стимулирует последний через другой участок связи, независимо от NO. Благоприятный профиль эффективности и безопасности риоцигуата был продемонстрирован в исследованиях PATENT-1,2. На фоне терапии у пациентов наблюдалось улучшение переносимости физической нагрузки, функционального класса, а также ряда других показателей. Рассмотрены исследования, которые свидетельствуют о целесообразности применения смены терапии в клинической практике. В частности, в статье проведен детальный разбор исследования REPLACE. Оно продемонстрировало значительно большую вероятность достижения клинического улучшения и значительное снижение темпов развития клинического ухудшения при переключении пациентов с ЛАГ с ингибиторов ФДЭ-5 на риоцигуат. Данная терапия хорошо переносилась, и может быть рассмотрена как стратегия ведения пациентов промежуточного риска при недостаточном ответе пациента на ингибиторы ФДЭ-5. В заключении отмечается необходимость планирования потребности в специфической терапии легочной артериальной гипертензии в регионе с целью быстрой эскалации терапии для достижения низкого риска летальности у этих пациентов.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>легочная артериальная гипертензия</kwd><kwd>риоцигуат</kwd><kwd>ингибиторы фосфодиэстеразы типа 5</kwd><kwd>оксид азота</kwd><kwd>растворимая гуанилатциклаза</kwd><kwd>профиль риска</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pulmonary arterial hypertension</kwd><kwd>riociguat</kwd><kwd>phosphodiesterase type 5 inhibitors</kwd><kwd>nitric oxide</kwd><kwd>soluble guanylate cyclase</kwd><kwd>risk profile</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Статья опубликована при поддержке компании АО «БАЙЕР».</funding-statement><funding-statement xml:lang="en">Article supported by Bayer, JSC.</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">Galie N., Humbert M., Vachiery J.L., et al. 2015 ESC/ERS Guidelines for the diagnosis and treatment of pulmonary hypertension: The Joint Task Force for the Diagnosis and Treatment of Pulmonary Hypertension of the European Society of Cardiology (ESC) and the European Respiratory Society (ERS): Endorsed by: Association for European Paediatric and Congenital Cardiology (AEPC), International Society for Heart and Lung Transplantation (ISHLT).
