To study the possibility of enhancing the antianginal effect of long-acting nitrates by their combination with trimetazidine in patients with stable angina. Material and methods. Patients with ischemic heart disease (IHD, stable angina; n=55) were included into the study. Patients were randomized to receive trimetazidine 35 mg 2 times a day (intervention group) or placebo (control group) in addition to standard therapy. A daily number of angina attacks, amount of short-acting nitroglycerin tablets consumed per week, exercise tolerance by the bicycle ergometry with the calculation of the threshold power and the work capacity were assessed at baseline and after 2 months of the drugs taking, as well as 2 months after the drugs withdrawal. Results. Significant reduction in nitroglycerin tablets consumption (1 month — by 61.8%, after 2 months — 72.5%, p&lt;0.05) were found in the intervention group compared with the control group. Low intake of nitroglycerin compared with baseline (p&lt;0.05) was maintained for 2 months after discontinuation of study drug. Significant increase in the threshold power (1 month — by 32.3%, after 2 months — 37.5%, p&lt;0.05) was observed in the intervention group compared to baseline and with the control group. Conclusion. Trimetazidine in the treatment of stable angina has high clinical efficacy.</p></abstract><trans-abstract xml:lang="ru"><p>Цель. Изучить возможность усиления антиангинальной эффективности пролонгированных нитратов у больных стабильной стенокардией путем их комплексного применения с триметазидином. Материал и методы. В исследование были включены 55 больных с ишемической болезнью сердца (ИБС, стабильная стенокардия). Пациенты рандомизированы в группы приема триметазидина 35 мг 2 раза в сутки (основная группа) и плацебо (контрольная группа) в дополнение к стандартной терапии. Исходно и через 2 мес приема препаратов, и через 2 мес после их отмены у пациентов определяли тяжесть ИБС с оценкой суточной частоты ангинозных приступов, количества потребляемых в неделю таблеток нитроглицерина, физической активности методом парных велоэргометрий с расчетом пороговой мощности и объема выполненной работы. Результаты. В основной группе по сравнению с контрольной группой отмечали значимое сокращение количества потребляемых больными таблеток нитроглицерина в неделю: через 1 мес — на 61,8%, через 2 мес — на 72,5%. После отмены исследуемых препаратов низкий уровень потребления нитроглицерина в сравнении с исходным (р&lt;0,05) сохранялся в течение 2 мес. В группе 1 отмечали статистически значимое повышение пороговой мощности: через 1 мес — на 32,3%, через 2 мес — на 37,5% в сравнении с исходным уровнем и при сравнении с контрольной группой (р&lt;0,05). Заключение. Триметазидин в комплексной терапии стабильной стенокардии обладает высокой клинической эффективностью.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>стенокардия</kwd><kwd>ишемическая болезнь сердца</kwd><kwd>триметазитдин</kwd><kwd>дженерики</kwd></kwd-group><kwd-group xml:lang="en"><kwd>angina</kwd><kwd>ischemic heart disease</kwd><kwd>trimetazidine</kwd><kwd>generics</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">Dorofeev V.L.
