Сравнение эффективности первичного чрескожного коронарного вмешательства (пЧКВ) и фармакоинвазивной стратегии (ФИС) реваскуляризации, а также изучение влияния сроков их проведения на состояние морфофункциональных и электрофизиологических характеристик миокарда у больных инфарктом миокарда с подъемом сегмента ST.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Включено 185 пациентов в возрасте 53±9 лет. На 7-10-е сутки больным проводили магнитно-резонансную томографию (МРТ) сердца, спекл-трекинг эхокардиографию (ЭхоКГ), холтеровское мониторирование электрокардиограммы (ХМ ЭКГ).</p></sec><sec><title>Результаты</title><p>Результаты. Обследуемых разделили на группы: группа ранней реперфузии "РР" — 97 человек, у которых время от начала болевого синдрома до реваскуляризации составило ≲180 мин; группа отсроченной реперфузии "ОР" — 88 больных с временем до реваскуляризации &gt;180 мин. По данным МРТ масса рубцовой ткани в группе "ОР" составила 24,7 (13,6; 42,9) г vs 15,9 (5,9; 30,7) г в группе "РР" (р=0,003). В группе "РР" наблюдалась более выраженная доля гетерогенной зоны относительно рубца по сравнению с группой "ОР" (р=0,018). Индекс глобального контрастирования в группе "РР" составил 17,7 (10,3; 33,1)%, в группе "ОР" — 25 (16,2; 38,2)% (р=0,014). По результатам ЭхоКГ выявлены более низкие значения эффективности глобальной работы при одновременном увеличении глобальной потерянной работы в группе "ОР" (р&lt;0,05). По данным ХМ ЭКГ в группе "РР" частота желудочковой экстрасистолии высоких градаций составила 1% vs 9% в группе "ОР" (р=0,011). На следующем этапе 97 пациентов с временем реперфузии ≲180 мин разделили на группы: 1-я — 54 человека, у которых использовали ФИС; 2-я — 43 больных с пЧКВ. По данным МРТ сердца, спекл-трекинг ЭхоКГ, ХМ ЭКГ различий между группами не выявлено.</p></sec><sec><title>Заключение</title><p>Заключение. Задержка реперфузии &gt;180 мин сопряжена с наиболее неблагоприятными характеристиками ишемического повреждения по данным МРТ, миокардиальной работы по спекл-трекинг ЭхоКГ, показателей ХМ ЭКГ. Сравнительный анализ пациентов с пЧКВ и ФИС, проведенными в первые 180 мин, не продемонстрировал различий в состоянии морфофункциональных и электрофизиологических параметров миокарда.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To compare the effectiveness of primary percutaneous coronary intervention (PPCI) and a pharmacoinvasive strategy (PIs) for revascularization, and to study the impact of their timing on the morphofunctional and electrophysiological myocardial characteristics in patients with ST-segment elevation myocardial infarction.</p></sec><sec><title>Material and methods</title><p>Material and methods. A total of 185 patients aged 53±9 years were included. On days 7-10, patients underwent cardiac magnetic resonance imaging (MRI), speckletracking echocardiography, and Holter monitoring.</p></sec><sec><title>Results</title><p>Results. Subjects were divided into following groups: the early reperfusion (ER) group included 97 patients with an onset-to-revascularization time ≲180 minutes; and the delayed reperfusion (DR) group included 88 patients with an onset-to-revascularization time &gt;180 minutes. According to MRI, scar tissue mass in the DR group was 24,7 (13,6; 42,9) g versus 15,9 (5,9; 30,7) g in the ER group (p=0,003). In the ER group, a more pronounced proportion of the heterogeneous area relative to the scar was observed compared to the DR group (p=0,018). The global contrast index in the ER group was 17,7 (10,3; 33,1)%, and in the DR group — 25 (16,2; 38,2)% (p=0,014). According to the echocardiography, lower values of global work efficiency with a simultaneous increase in global wasted work were revealed in the DR group (p&lt;0,05). According to Holter monitoring data, the incidence of high-grade premature ventricular contractions in the ER group was 1% vs 9% in the DR group (p=0,011). At the next stage, 97 patients with a reperfusion time ≲180 min were divided into following groups: group 1-54 patients in whom PIs was used; group 2-43 patients with PPCI. No differences were found between the groups according to cardiac MRI, speckle-tracking echocardiography, and Holter monitoring.</p></sec><sec><title>Conclusion</title><p>Conclusion. A reperfusion delay of &gt;180 min is associated with the most unfavorable characteristics of ischemic injury according to MRI, myocardial work according to speckle-tracking echocardiography, and Holter monitoring data. A comparative analysis of patients with PPCI and PIs performed in the first 180 minutes did not demonstrate differences in morphofunctional and electrophysiological myocardial characteristics.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>инфаркт миокарда с подъемом сегмента ST</kwd><kwd>реваскуляризация</kwd><kwd>магнитно-резонансная томография сердца</kwd><kwd>ишемическое повреждение</kwd><kwd>миокардиальная работа</kwd><kwd>желудочковые аритмии</kwd><kwd>вариабельность сердечного ритма</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ST-segment elevation myocardial infarction</kwd><kwd>revascularization</kwd><kwd>cardiac magnetic resonance imaging</kwd><kwd>ischemic injury</kwd><kwd>myocardial work</kwd><kwd>ventricular arrhythmias</kwd><kwd>heart rate variability</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">Николаева А.
