При отсутствии лечения катехоламинергическая полиморфная желудочковая тахикардия сопряжена с высоким уровнем летальности. Основой медикаментозной терапии заболевания являются бета-адреноблокаторы, монотерапия которыми часто оказывается недостаточно эффективной, что создает предпосылки для изучения комбинированной антиаритмической терапии, применение которой будет способствовать снижению рисков развития аритмогенных событий и внезапной сердечной смерти. Цель исследования: сравнить эффективность и безопасность применения монотерапии бета-адреноблокаторами и комбинированной терапии (бета-адреноблокатор совместно с пропафеноном) у пациентов с катехоламинергической полиморфной желудочковой тахикардией.Материалы и методы. В исследование включены 68 пациентов с установленным в детском возрасте диагнозом «Катехоламинергическая полиморфная желудочковая тахикардия». Критерии эффективности терапии: отсутствие нарушений сердечного ритма высоких градаций, отсутствие аритмогенных событий на фоне терапии.Результаты. Комбинированная антиаритмическая терапия с применением бета-адреноблокатора и препарата IC класса пропафенона была более эффективна в предотвращении нагрузочных нарушений сердечного ритма (p=0,00002) и аритмогенных событий (p=0,02) по сравнению с лечением исключительно бета-адреноблокаторами.Выводы. Полученные данные позволяют констатировать, что комбинированная терапия, включающая бета-адреноблокатор и пропафенон превосходит по эффективности монотерапию с применением только бета-адреноблокатора у пациентов с катехоламинергической полиморфной желудочковой тахикардией. Необходимо проведение дальнейших исследований в этой области с возможным последующим включением пропафенона в международные клинические рекомендации.</p></abstract><trans-abstract xml:lang="en"><p>Summary. Catecholaminergic polymorphic ventricular tachycardia (CPVT) is an inherited channelopathy characterized by bidirectional and/or polymorphic ventricular tachycardia triggered by physical or emotional stress. CPVT is associated with a high mortality rate if left untreated. Although beta-blockers are the cornerstone of pharmacologic management for catecholaminergic polymorphic ventricular tachycardia, their efficacy as monotherapy is often limited. This limitation highlights the need to investigate combination antiarrhythmic therapies that may more effectively reduce the risk of arrhythmogenic events and sudden cardiac death.Objective. To compare the efficacy and safety of beta-blocker monotherapy versus combination therapy (beta-blocker plus propafenone) in patients with catecholaminergic polymorphic ventricular tachycardia.Materials and Methods. The study included 68 patients diagnosed with catecholaminergic polymorphic ventricular tachycardia during childhood. Efficacy criteria for the therapy included the absence of ventricular and supraventricular arrhythmias and the absence of arrhythmogenic events during treatment.Results. Combined antiarrhythmic therapy with a beta-blocker and the class IC antiarrhythmic agent propafenone was significantly more effective in preventing stress-induced cardiac rhythm disturbances (p=0.00002) and arrhythmogenic events (p=0.02) compared to beta-blocker monotherapy.Conclusions. These results indicate that combination therapy with a beta-blocker and propafenone is more effective over beta-blocker monotherapy in patients with catecholaminergic polymorphic ventricular tachycardia. Further research is warranted to confirm these findings and to assess the potential inclusion of propafenone in future international clinical guidelines for catecholaminergic polymorphic ventricular tachycardia management.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>пропафенон</kwd><kwd>катехоламинергическая полиморфная желудочковая тахикардия</kwd><kwd>двунаправленная желудочковая тахикардия</kwd><kwd>флекаинид</kwd><kwd>внезапная сердечная смерть</kwd><kwd>бета-адреноблокаторы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>propafenone</kwd><kwd>catecholaminergic polymorphic ventricular tachycardia</kwd><kwd>bidirectional ventricular tachycardia</kwd><kwd>flecainide</kwd><kwd>sudden cardiac death</kwd><kwd>beta-blockers</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">Roston T.M., Yuchi Z., Kannankeril P.J., Hathaway J., Vinocur J.M., Etheridge S.P., et al.
