According to the literature, the in-hospital and long-term mortality rates in patients with unstable angina (UA) are lower than those in the patients with myocardial infarction (MI).</p> <p><bold>Aim</bold>: To evaluate the in-hospital and long-term mortality rates and their predictors in patients undergoing in-patient treatment for acute coronary syndrome (MI and UA) in the regional cardiovascular center with the service territory of 1 million persons.</p> <p><bold>Materials and methods</bold>: This retrospective registry study enrolled 1130 patients (715 [63.3%] men, 415 [36.7%] women) who were treated for UA and MI in the regional cardiovascular center in 2019. Based on the discharge diagnosis, the patients were divided into two groups: patients with MI (n = 766) and those with an UA episode (n = 364). The in-hospital and delayed mortality rates, as well as their predictors, were analyzed in both groups. The mean duration of the follow-up was 17.8 ± 3.6 months.</p> <p><bold>Results</bold>: The in-hospital mortality in patients with confirmed MI was 11.1% (85 patients) versus 0.27% (1 patient) in the UA patients (p &lt; 0.001). The independent predictors of in-hospital mortality in MI patients were a decreased left ventricular ejection fraction (LV EF) (odds ratio (OR) 0.9021, 95% confidence interval (CI) 0.8209–0.9914, p = 0.0324), chronic kidney disease C3a and above (OR 9.3205, 95% CI 2.6706–32.5283, p = 0.0005), and the extension of coronary involvement at coronary angiography (OR 1.3526, 95% CI 1.0667–0.0127, p = 0.0127). The long-term mortality in MI patients was 10.4% (72 patients) with no significant difference from that in UA patients (9.9%, 36 patients, p = 0.76). The independent predictors of long-term mortality after MI were older age (OR 1.12, 95% CI 1.01–1.22, p = 0.0052), chronic kidney disease C3a and above (OR 2.3375, 95% CI 1.1392–4.7963, p = 0.0206), decreased EF (OR 0.8895, 95% CI 0.73–0.99, p = 0.0364), atrial fibrillation on admission (OR 3.1462, 95% CI 1.3510–7.3268, p = 0.0079), and diabetes mellitus (OR 2.3163, 95% CI 1.2552–4.2744, p = 0.0072). In the UA patients, the predictors of the long-term mortality were a decrease in LV EF (OR 0.9139, 95% CI 0.8683–0.9619, p = 0.0006) and in blood hemoglobin level (OR 0.9729, 95% CI 0.9544–0.9917, p = 0.0050).</p> <p><bold>Conclusion</bold>: The in-hospital mortality in UA patients is lower than that in MI patients, with comparable long-term mortality. This indicates the need of active follow-up of the patients with past UA, irrespective of the endovascular assessment and intervention.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность</bold>. Объем повреждения миокарда в значительной степени определяет как госпитальный, так и отсроченный прогноз у пациентов с острым коронарным синдромом. По данным литературы, госпитальная и отсроченная летальность среди пациентов с нестабильной стенокардией (НС) ниже в сравнении с больными, перенесшими инфаркт миокарда (ИМ).</p> <p><bold>Цель</bold> – оценить госпитальный и отдаленный прогнозы и их предикторы у пациентов, проходивших стационарное лечение по поводу острого коронарного синдрома (ИМ и НС) в региональном сосудистом центре с зоной обслуживания 1 млн человек.</p> <p><bold>Материал и методы</bold>. В ретроспективное регистровое исследование включены 1130 пациентов (715 (63,3%) мужчин, 415 (36,7%) женщин), проходивших в 2019 г. лечение по поводу НС и ИМ в региональном сосудистом центре. На основании диагноза, установленного при выписке, пациенты были разделены на 2 группы: перенесших ИМ (n = 766) и эпизод НС (n = 364). В обеих группах анализировали уровень госпитальной и отсроченной летальности, а также их предикторы. Средняя длительность наблюдения составила 17,8 ± 3,6 месяца.</p> <p><bold>Результаты</bold>. Среди больных с верифицированным ИМ госпитальная летальность составила 11,1% (85 пациентов) против 0,27% (1 пациент) в группе больных НС (p &lt; 0,001). Независимыми предикторами госпитальной летальности при ИМ были снижение фракции выброса левого желудочка (ФВ ЛЖ) (отношение шансов (ОШ) 0,9021, 95% доверительный интервал (ДИ) 0,8209–0,9914, p = 0,0324), хроническая болезнь почек стадия 3а и выше (ОШ 9,3205, 95% ДИ 2,6706–32,5283, p = 0,0005) и объем поражения коронарного русла по данным коронароангиографии (ОШ 1,3526, 95% ДИ 1,0667–0,0127, p = 0,0127). Отсроченная летальность при ИМ составила 10,4% (72 пациента) и значимо не отличалась от таковой при НС – 9,9% (36 пациентов), p = 0,76. У пациентов, перенесших ИМ, независимыми предикторами отдаленной летальности были возраст (ОШ 1,12, 95% ДИ 1,01–1,22, p = 0,0052), хроническая болезнь почек стадия 3а и выше (ОШ 2,3375, 95% ДИ 1,1392–4,7963, p = 0,0206), снижение ФВ (ОШ 0,8895, 95% ДИ 0,73–0,99, p = 0,0364), фибрилляция предсердий на электрокардиограмме при поступлении (ОШ 3,1462, 95% ДИ 1,3510–7,3268, p = 0,0079) и сахарный диабет (ОШ 2,3163, 95% ДИ 1,2552–4,2744, p = 0,0072). У больных с НС предикторами неблагоприятного прогноза в отдаленном периоде были снижение ФВ ЛЖ (ОШ 0,9139, 95% ДИ 0,8683–0,9619, p = 0,0006) и содержания гемоглобина в крови (ОШ 0,9729, 95% ДИ 0,9544–0,9917, p = 0,005).</p> <p><bold>Заключение</bold>. Госпитальная летальность среди пациентов, перенесших НС, ниже, чем при ИМ, при этом отдаленная летальность сопоставима. Это свидетельствует о необходимости активного диспансерного наблюдения пациентов, перенесших НС, вне зависимости от проведенного эндоваскулярного обследования и лечения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>myocardial infarction</kwd><kwd>unstable angina</kwd><kwd>in-hospital mortality</kwd><kwd>long-term mortality</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>инфаркт миокарда</kwd><kwd>нестабильная стенокардия</kwd><kwd>госпитальная летальность</kwd><kwd>отдаленная летальность</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Fladseth K, Wilsgaard T, Lindekleiv H, Kristensen A, Mannsverk J, Løchen ML, Njølstad I, Mathiesen EB, Trovik T, Rotevatn S, Forsdahl S, Schirmer H.
