Настоящее исследование было одноцентровым наблюдательным когортным. В общей сложности в исследование вошли 60 пациентов с первичным STEMI и успешной коронарной реперфузией в первые 12 ч от начала заболевания, все были обследованы с использованием магнитного резонанса сердца с контрастным усилением на 2-й день после STEMI. Данное исследование было зарегистрировано в ClinicalTrials.gov, номер: NCT03677466.</p></sec><sec><title>Результаты</title><p>Результаты. Общая частота явлений МСО и ГПМ составляет 68,3%. Различные фенотипы микрососудистого повреждения миокарда распределены следующим образом: только МСО – 17%, только ГПМ – 15%, комбинация МСО и ГПМ – 36%, без микрососудистого повреждения миокарда – 32% обследованных. У пациентов только с МСО и комбинацией МСО и ГПМ наблюдался более длительный период «боль – реперфузия» по сравнению с пациентами без этих явлений: 205 (140–227) и 193 (95–400) против 130 (91–160) мин (p = 0,049). Напротив, время ишемии миокарда у пациентов только с ГПМ (113 мин) не отличалось от показателя у пациентов без этих явлений. Все пациенты были разделены на группу фармакоинвазивной стратегии коронарной реперфузии (ФИС) (n = 39) и группу первичного чрескожного вмешательства (ПЧТКА) (n = 21). Основные клинические и анамнестические характеристики на исходном уровне не различались между этими группами. Количество случаев только МСО и только ГПМ не различалось между группами ФИС и ПЧТКА: 17,9 против 14,2% и 12,8 против 19,1% в группах ФИС и ПЧТКА соответственно. Была обнаружена тенденция к снижению частоты встречаемости комбинации МСО и ГПМ в группе ФИС по сравнению с группой ПЧТКА: 30,8 против 47,6% (р = 0,09).</p></sec><sec><title>Заключение</title><p>Заключение. Общая частота явлений МСО и ГПМ у пациентов с первичным STEMI после коронарной реперфузии достигает 68,3%. Сочетание этих явлений развивается чаще, чем каждое из них в отдельности: 36 против 17% (только МСО) и 15% (только ГПМ). Развитие только МСО и комбинации МСО с ГПМ связано с большей продолжительностью ишемии миокарда по сравнению с группой без этих явлений. Разницы во времени ишемии миокарда между группой только с ГПМ и группой без этих явлений нет. Тромболизис не увеличивает частоту возникновения ГПМ в группе ФИС по сравнению с группой ПЧТКА. Наблюдается тенденция к снижению встречаемости комбинации МСО и ГПМ в группе ФИС по сравнению с группой ПЧТКА: 30,8 против 47,6% (р = 0,09). </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. The aim of this study was to evaluate the prevalence of microvascular obstruction (MVO) and intramyocardial hemorrhage (IMH), their combination, and relationship to the clinical and anamnestic characteristics in patients with primary STEMI after coronary reperfusion.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. A single-center observational cohort study comprised a total of 60 patients with primary STEMI and successful coronary reperfusion within 12 hours of the onset of symptoms. All patients were studied using a contrast-enhanced cardiac magnetic resonance imaging (CE-MRI) at day 2 after STEMI. The study protocol was registered on ClinicalTrials.gov (Identifier: NCT03677466).</p></sec><sec><title>Results</title><p>Results. The total occurrence rate of MVO and IMH phenomena was 68.3% including MVO only in 17% of patients, IMH only in 15% of cases, combination of MVO and IMH in 36% cases, and without a microvascular myocardial injury in 32% of cases. The patients with MVO only and combination of MVO and IMH experienced a longer time of ischemia versus patients without these conditions: 205 (140–227) and 193 (95–400) versus 130 (91–160) min (p = 0.049). On the contrary, the time of myocardial ischemia did not differ between patients with IMH only (113 min) and patients without it. Then, patients were assigned to the group of pharmaco-invasive strategy of coronary reperfusion (PIS) (n = 39) and the group of primary percutaneous intervention (PPCI) (n = 21). The incidence of MVO only and IMH only was equal in PIS and PPCI groups: 17.9% versus 14.2% and 12.8% versus 19.1% in PIS and PPCI groups, respectively. The tendency to a decrease in the incidence of combined MVO and IMH was observed in PIS group compared to PPCI group: 30.8% versus 47.6% (p = 0.09).</p></sec><sec><title>Conclusion</title><p>Conclusion. The combination of MVO and IMH phenomena in patients with primary STEMI after coronary reperfusion developed more often than each of these phenomena separately. The development of MVO only and combination of MVO and IMH was associated with a longer duration of myocardial ischemia. A total frequency of combination of MVO and IMH phenomena in patients with primary STEMI after coronary reperfusion was as high as 68.3%. Combination of these phenomena developed more frequently than each of them separately: 36% versus 17% (MVO only) and 15% (IMH only). No difference was observed in the duration of myocardial ischemia between the groups with MVO only and without it. The thrombolysis did not increase the occurrence of IMH in PIS group compared with PPCI group. There was a tendency to a decrease in the incidence of combination of MVO and IMH in PIS group compared to PPCI group: 30.8 versus 47.6% (р = 0.09). </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>инфаркт миокарда</kwd><kwd>микрососудистая обструкция</kwd><kwd>геморрагическое пропитывание миокарда</kwd><kwd>первичное чрескожное вмешательство</kwd><kwd>тромболизис</kwd><kwd>кардио-МРТ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>myocardial infarction</kwd><kwd>microvascular obstruction</kwd><kwd>intramyocardial hemorrhage</kwd><kwd>primary PCI</kwd><kwd>thrombolysis</kwd><kwd>cardiac magnetic resonance</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">Ma M., Diao K., Yang Z., Zhu Y., Guo Y., Yang M. et al.
