Выявить основные клинико-лабораторно-инструментальные характеристики больных с острым коронарным синдромом без подъема сегмента ST (ОКСбпST) различных групп риска развития неблагоприятных ишемических событий, а также описать госпитальные исходы заболевания.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В ретроспективный анализ включены 600 пациентов, которые были госпитализированы в региональный сосудистый центр с января 2019г по январь 2021г с диагнозом ОКСбпST.</p></sec><sec><title>Результаты</title><p>Результаты. Пациенты стратифицированы на группы очень высокого — 208 (34,7%), высокого — 196 (32,7%), умеренного — 108 (18%) и низкого — 88 (14,6%) риска. В группах высокого и очень высокого риска больные были старше, характеризовались значимым индексом коморбидности, повышенным риском кровотечений, снижением фракции выброса левого желудочка и скорости клубочковой фильтрации в сравнении с пациентами остальных групп (р&lt;0,05). Для пациентов очень высокого риска были характерны ассоциированные клинические состояния, преимущественно инфекционные заболевания и декомпенсация хронической сердечной недостаточности. Неблагоприятный исход госпитализации наблюдался у 44 (7,3%) пациентов. Вероятность развития летального исхода в группе очень высокого риска (33; 15,9%) была выше, чем в группе низкого (2; 2,3%) (Odds Ratio 8,1 (95% доверительный интервал: 1,9-34,6); p=0,01). Вне зависимости от степени риска отмечена высокая (53,5%) вероятность завершения инвазивной коронароангиографии исключительно диагностической процедурой. Большинство наблюдаемых осложнений в результате инвазивной коронароангиографии были характерны для групп высокого (18,3%) и очень высокого риска (21,5%).</p></sec><sec><title>Заключение</title><p>Заключение. Больные ОКСбпST категорий очень высокого/высокого риска неблагоприятных ишемических событий представляют собой гетерогенную группу с наличием таких кардиальных и внекардиальных патологий, как высокие уровни коморбидности и риски кровотечения, снижение фракции выброса левого желудочка и скорости клубочковой фильтрации, ассоциированные клинические состояния.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To identify the main clinical and paraclinical characteristics of patients with non-ST segment elevation acute coronary syndrome (NSTE-ACS) of various risk groups for adverse ischemic events, as well as to describe the in-hospital outcomes of the disease.</p></sec><sec><title>Material and methods</title><p>Material and methods. The retrospective analysis included 600 patients who were hospitalized at the regional vascular center from January 2019 to January 2021 with a diagnosis of NSTE-ACS.</p></sec><sec><title>Results</title><p>Results. Patients were stratified into very high — 208 (34,7%), high — 196 (32,7%), moderate — 108 (18%) and low — 88 (14,6%) risk groups. In the highand very high-risk groups, patients were older, characterized by a significant comorbidity index, increased bleeding risk, decreased left ventricular ejection fraction and glomerular filtration rate in comparison with patients of other groups (p&lt;0,05). Very highrisk patients were characterized by associated clinical conditions, predominantly infectious diseases and decompensated heart failure. Unfavorable outcome of hospitalization was observed in 44 (7,3%) patients. The death probability in the very high-risk group (33; 15,9%) was higher than in the low-risk group (2; 2,3%) (Odds ratio 8,1 (95% confidence interval: 1,9-34,6); p=0,01). Regardless of the risk degree, there was a high (53,5%) likelihood of completing invasive coronary angiography as a diagnostic procedure. Most of the observed complications as a result of invasive coronary angiography were characteristic of the high(18,3%) and very high-risk groups (21,5%).</p></sec><sec><title>Conclusion</title><p>Conclusion. NSTE-ACS patients at very high/high risk of adverse ischemic events represent a heterogeneous group with cardiac and noncardiac pathologies with high comorbidity and bleeding risks, decreased left ventricular ejection fraction and glomerular filtration rate, and associated clinical conditions.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>острый коронарный синдром без подъема сегмента ST</kwd><kwd>стратификация риска</kwd><kwd>коморбидность</kwd><kwd>инвазивная коронароангиография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>non-ST segment elevation acute coronary syndrome</kwd><kwd>risk stratification</kwd><kwd>comorbidity</kwd><kwd>invasive coronary angiography</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">Everett CC, Fox KA, Reynolds C, et al.
