В  сравнительном аспекте оценить изменения клинико-демографических характеристик больных с острым коронарным синдромом без подъема сегмента ST (ОКСбпST) и  показатели качества оказания медицинской помощи в период пандемии COVID-19 (COrona Virus Disease 2019).</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Использовали данные, полученные из историй болезни. Статистическую обработку данных проводили с  использованием пакета программ Statistica 10.0. В анализ вошли пациенты с ОКСбпST, проходившие лечение в 2020г (n=524) и в 2019г (n=395). Группу дальнейшего анализа составили больные инфарктом миокарда без подъема сегмента ST, проходившие лечение в 2020г (n=233) в сравнении с 2019г (n=221).</p></sec><sec><title>Результаты</title><p>Результаты. Выявили увеличение относительного количества пациентов с  нестабильной стенокардией в  группе ОКСбпST. У  5,5% из числа больных с  ОКСбпST была верифицирована коронавирусная инфекция. Из них пневмония диагностирована у 10 (34,5%) пациентов, в  респираторные госпитали были переведены 11 (37,9%) пациентов, остальные 18 (62,1%) были выписаны на амбулаторное лечение. Инфицированные пациенты имели больший риск госпитальной летальности по шкале GRACE (Global Registry of Acute Coronary Events) относительно общей когорты пациентов  — 2,0 (1,0;9,0) vs 1,0 (0,8;3,0) (р=0,04). Инвазивной коронароангиографии подверглись 215 (92,3%) пациентов, что выше, чем в 2019г (78,7%) (p&lt;0,001). Установлено увеличение частоты реваскуляризации пациентов ≥75 лет (p=0,01).</p></sec><sec><title>Заключение</title><p>Заключение. Вирусная пандемия привела к  изменению клинических характеристик пациентов, при этом не оказала существенного влияния на объем эндоваскулярных вмешательств и  основные показатели качества оказания медицинской помощи пациентам с ОКСбпST в отделении неотложной кардиологии.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To perform a comparative assessment of the clinical and demographic characteristics of patients with non-ST elevation acute coronary syndrome (NSTE-ACS) and health care quality during the coronavirus disease 2019 (COVID-19) pandemic.</p></sec><sec><title>Material and methods</title><p>Material and methods. Data obtained from medical records were used. Statistical processing was performed using the Statistica 10.0 software package. The analysis included patients with NSTE-ACS treated in 2020 (n=524) and 2019 (n=395). The group for further analysis consisted of patients with non-ST elevation myocardial infarction treated in 2020 (n=233) compared to 2019 (n=221).</p></sec><sec><title>Results</title><p>Results. An increase in the relative number of patients with unstable angina in the NSTE-ACS group was revealed. COVID-19 was verified in 5,5% of patients with NSTE-ACS. Of these, pneumonia was diagnosed in 10 (34,5%) patients, while 11 (37,9%) patients were transferred to pulmonary hospitals. The remaining 18 (62,1%) patients were discharged for outpatient treatment. Infected patients had a higher risk of in-hospital mortality according to the Global Registry of Acute Coronary Events (GRACE) score relative to general cohort of patients — 2,0 (1,0; 9,0) vs 1,0 (0,8; 3,0) (p=0,04). In addition, 215 (92,3%) patients underwent invasive coronary angiography, which is higher than in 2019 (78,7%) (p&lt;0,001). An increase in revascularization prevalence in patients ≥75 years old was found (p=0,01).</p></sec><sec><title>Conclusion</title><p>Conclusion. COVID-19 pandemic has led to a change in the clinical characteristics of patients, while not having a significant impact on the scope of endovascular interventions and health care quality for patients with NSTE-ACS in the emergency cardiology department.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>острый коронарный синдром</kwd><kwd>чрескожное коронарное вмешательство</kwd><kwd>инфаркт миокарда</kwd><kwd>COVID-19</kwd><kwd>регистр</kwd></kwd-group><kwd-group xml:lang="en"><kwd>acute coronary syndrome</kwd><kwd>percutaneous coronary intervention</kwd><kwd>myocardial infarction</kwd><kwd>COVID-19</kwd><kwd>registry</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы заявляют, что у них нет известных конкурирующих финансовых интересов или личных отношений, которые могли бы повлиять на работу, описанную в этой статье.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Национальный проект “Здравоохранение”. https://minzdrav.gov.ru/poleznyeresursy/natsproektzdravoohranenie.</mixed-citation><mixed-citation xml:lang="en">National project “Healthcare”. https://minzdrav.gov.ru/poleznyeresursy/natsproektzdravoohranenie.
