Despite the progress in the diagnostics of microvascular angina (МА) there is no effective pathogenetic therapy.</p></sec><sec><title>Aim</title><p>Aim. To study the effect of trimetazidine and sulodexide as a part of drug therapy on clinical manifestations, exercise tolerance, quality of life, myocardial perfusion and endothelial function in patients with MA.</p></sec><sec><title>Material and methods</title><p>Material and methods. Patients with MA (n=90) were included into the study and randomized into 3 groups. Patients of the first group (control; n=30) received standard antianginal therapy. The second group (treatment group; n=30) received standard therapy and sulodexide (1 ampoule of 600 IU intramuscularly for 10 days, then 1 capsule of 250 IU, 2 times a day). Patients of the third group (treatment group; n=30) received standard therapy and trimetazidine with modified release 35 mg 2 times a day. Evaluation of angina symptoms and quality of life by the Seattle Questionnaire, stress (treadmill) test, positron emission tomography (baseline, adenosine test, cold-pressor test), peripheral arterial tonometry were performed at baseline and 3 months after starting treatment.</p></sec><sec><title>Results</title><p>Results. After 3 months of treatment a significant improvement in symptoms, quality of life and results of stress-test were observed only among patients of treatment groups, most pronounced in the 3rd group. Patients of this group showed an increase in myocardial blood flow &gt;25% according to positron emission tomography (from 86.2±29.7 to 129.5±41.0 ml/100g/min, p&lt;0.05 for anterior interventricular artery; from 93.3±30.5 to 131.7±32.7 ml/100g/min, p&lt;0.05 for circumflex artery; from 91.3±30.4 to 135.9±41.1 ml/100g/min, p&lt;0.05 for right coronary artery) and a significant increase in coronary reserve, as well as an improvement in endothelial function: an increase in coronary reserve of endothelium-dependent vasodilation, an increase in the reactive hyperemia index according to peripheral arterial tonometry (from 1.44±0.14 to 1.73±0.18, p&lt;0.001).</p></sec><sec><title>Conclusion</title><p>Conclusion. Improvement of the clinical picture, quality of life, myocardial perfusion, and endothelial function was observed among microvascular angina patients who were treated with standard antianginal therapy and trimetazidine.</p></sec></abstract><trans-abstract xml:lang="ru"><p>Несмотря на достигнутые успехи в диагностике микроваскулярной стенокардии (МВС), эффективная патогенетическая терапия заболевания не разработана.</p><sec><title>Цель</title><p>Цель. Изучить влияние триметазидина и сулодексида в составе медикаментозной терапии на клинические проявления, переносимость физических нагрузок, качество жизни, перфузию миокарда и эндотелиальную функцию у больных МВС.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Обследовано 90 пациентов с МВС, сформированы 3 группы. Первая (контрольная; n=30) получала стандартную ан-тиангинальную терапию. Вторая группа (лекарственного воздействия; n=30) получала стандартную терапию и сулодексид по 1 ампуле 600 лекарственных единиц (ЛЕ) внутримышечно 10 дней, затем по 1 капсуле 250 ЛЕ 2 р/сут. Третья группа (лекарственного воздействия; n=30) получала стандартную терапию и дополнительно триметазидин МВ 35 мг 2 р/сут. Исходно и через 3 мес после начала лечения пациентам повторно были выполнены клиническая оценка функционального класса стенокардии, характера болевого синдрома и качества жизни с помощью Сиэтлского опросника, нагрузочный (тредмил) тест, позитронно-эмиссионная томография (ПЭТ) с пробами (холодовая и тест с аденозинтрифосфатом натрия), периферическая артериальная тонометрия (ПАТ).</p></sec><sec><title>Результаты</title><p>Результаты. Через 3 мес улучшение клинической картины, качества жизни и показателей стресс-теста наблюдалось только среди пациентов групп лекарственного воздействия, наиболее выраженные в группе 3. У данной группы больных отмечалось статистически значимое увеличение миокардиального кровотока (с 86,2±29,7 до 129,5±41,0 мл/100г/мин, p&lt;0,05 для передней межжелудочковой артерии; с 93,3±30,5 до 131,7±32,7 мл/100г/мин, p&lt;0,05 для огибающей артерии; с 91,3±30,4 до 135,9±41,1 мл/100г/мин, p&lt;0,05 для правой коронарной артерии), коронарного резерва по данным ПЭТ, а также улучшение эндотелиальной функции: повышение коронарного резерва эндотелий-зависимой вазодилатации и индекса реактивной гиперемии по данным ПАТ (с 1,44±0,14 до 1,73±0,18; p&lt;0,001).</p></sec><sec><title>Заключение</title><p>Заключение. У пациентов с МВС, помимо стандартной антиангинальной терапии получавших триметазидин, отмечалось улучшение клинической картины, качества жизни, перфузии миокарда и функции эндотелия.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>микроваскулярная стенокардия</kwd><kwd>диагностика</kwd><kwd>лечение</kwd><kwd>триметазидин</kwd><kwd>сулодексид</kwd></kwd-group><kwd-group xml:lang="en"><kwd>microvascular angina</kwd><kwd>treatment</kwd><kwd>diagnostics</kwd><kwd>trimetazidine</kwd><kwd>sulodexide</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">Makarovic Z., Makarovic S., Bilic-Cucic I., et al.
