Проведено одноцентровое регистровое наблюдательное исследование. В исследование включались больные, последовательно поступившие в НИИ кардиологии Томского НИМЦ с 1.01.2020 по 31.12.2021 гг., у которых на момент поступления был диагностирован ИМ, осложнившийся КШ, которым экстренно была начата ВАБК и у которых была достигнута реперфузия в инфаркт-связанной коронарной артерии (ИСКА). Согласно этим критериям в анализ были включены 23 пациента.</p></sec><sec><title>Результаты</title><p>Результаты. Средний возраст пациентов составил 79 лет. Мужчин и женщин было примерно поровну. Абсолютное большинство (78,2%) имели постинфарктный кардиосклероз, 86,9% гипертоническую болезнь, треть – сахарный диабет, почти половина – ожирение. У большинства из этих пациентов (73,9%) был ИМ с подъемом сегмента ST, у остальных – без подъема сегмента ST. 60,9% больных имели переднюю локализацию ИМ, остальные – нижнюю. Время боль-дверь составило в среднем 223 мин. Тромболизис на догоспитальном этапе был проведен в 9 (39%) случаях с эффективностью 55%. У большинства больных (n = 22) было выполнено стентирование ИСКА. ВАБК продолжалась в среднем 52,5 ч, летальность составила 69,5%. Все летальные исходы произошли в результате прогрессирования КШ. Статистически значимого различия по основным клинико-анамнестическим характеристикам между группами с установкой ВАБК до и после чрескожного коронарного вмешательства (ЧКВ) не обнаружено, хотя больные группы ВАБК до ЧКВ были моложе, имели более низкий уровень тропонина при поступлении, им чаще проводился тромболизис на догоспитальном этапе, у них чаще было достижение коронарной реперфузии TIMI-2-3 на момент ЧКВ и ниже летальность.</p></sec><sec><title>Выводы</title><p>Выводы. Частота проведения ВАБК при ИМ и КШ в нашем отделении составляет 8%. Летальность среди больных, которым проводилась ВАБК, достигает 69,5%, что не ниже, чем в общей группе КШ (55%). Сочетание установки ВАБК до проведения ЧКВ на фоне достигнутой коронарной реперфузии (спонтанной или тромболизисом) ассоциируется с тенденцией к снижению летальности по сравнению с установкой ВАБК после ЧКВ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To build a clinical and instrumental profile of patients with myocardial infarction (MI) complicated by the development of cardiogenic shock (CS) who underwent intra-aortic balloon pump (IABP) counterpulsation and evaluate the results of this treatment.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. The single-center observational registry study comprised patients with admitting diagnosis of MI complicated by CS who were admitted to Cardiology Research Institute of Tomsk NIMC from 01.01.2020 to 12.31.2021. All patients received emergency IABP at admission, and reperfusion of infarct-related artery was achieved. According to these criteria, a total of 23 patients were included in the analysis.</p></sec><sec><title>Results</title><p>Results. The average age of patients was 79 years. There were comparable numbers of men and women in study group. Vast majority of patients (78.2%) had postinfarction cardiosclerosis; 86.9% of patients had hypertension; third of patients had diabetes mellitus; and almost half of patients were obese. Most of these patients (73.9%) had MI with ST segment elevation; the rest of patients had MI without ST segment elevation. 60.9% of patients had anterior wall MI, and the rest of patients had inferior wall MI. The pain-to-door time was 223 minutes on average. Thrombolysis was performed in 9 cases (39%) at the prehospital stage with an efficiency of 55%. The majority of patients (n = 22) underwent coronary stenting of infarct-related artery. The duration of IABP was 52.5 hours an average, and the mortality rate was 69.5%. All fatal outcomes occurred as a result of CS progression. There were no statistically significant differences in the main clinical and anamnestic characteristics between the groups with the administration of IABP before and after PCI, although the patients in the group of IABP before PCI were younger, had a lower level of troponin at admission, more often achieved coronary reperfusion TIMI-2-3 at PCI, and had lower mortality.</p></sec><sec><title>Conclusion</title><p>Conclusion. The frequency of IABP administration to patients with MI and CS in our department was 8%. The mortality rate among patients who underwent IABP insertion reached 69.5%, which was not lower than the corresponding rate in the general group of CS (55%). The combination of IABP installation before PCI in the presence of achieved coronary reperfusion (spontaneous or due to thrombolysis) was associated with a tendency to decrease in mortality compared with the installation of IABP after PCI.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>инфаркт миокарда</kwd><kwd>кардиогенный шок</kwd><kwd>внутриаортальная баллонная контрпульсация</kwd><kwd>чрескожное коронарное вмешательство</kwd></kwd-group><kwd-group xml:lang="en"><kwd>myocardial infarction</kwd><kwd>cardiogenic shock</kwd><kwd>intra-aortic balloon pump</kwd><kwd>percutaneous coronary intervention</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">Вышлов Е.В., Рябов В.В.
