Разработать прогностическую многофакторную модель для раннего выявления острой коронарной окклюзии (ОКО) у пациентов с острым коронарным синдромом без подъема сегмента ST (ОКСбпST) с использованием методов машинного обучения и набора предикторов, доступных в первые часы госпитализации.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В ретроспективное наблюдательное исследование включены 1144 пациента с диагнозом инфаркта миокарда без подъема сегмента ST или нестабильной стенокардии, госпитализированные в региональный сосудистый центр в 2019-2021гг. Инвазивная коронарная ангиография была выполнена 900 пациентам, из них ОКО диагностирована у 64 пациентов (7,1%). Для выявления предикторов ОКО проведен анализ 149 клинических, анамнестических, лабораторных и инструментальных параметров, информация о которых была доступна в первые часы госпитализации. После отбора предикторов были разработаны прогностические модели с использованием методов машинного обучения: многофакторной логистической регрессии (МЛР), случайного леса, стохастического градиентного бустинга (XGBoost) и категориального бустинга (CatBoost). Оценка качества моделей проводилась по метрикам ROC-AUC, чувствительности (Sens), специфичности (Spec), Precision-Recall AUC (PR-AUC), меры качества вероятностных прогнозов (Brier-score), доли истинно положительных (PPV) и истинно отрицательных (NPV) результатов, F1-score и Accuracy.</p></sec><sec><title>Результаты</title><p>Результаты. Независимыми предикторами ОКО явились: впервые выявленные/новые нарушения локальной сократимости левого желудочка, скорость оседания эритроцитов &gt;15,5 мм/ч, холестерин липопротеинов высокой плотности &lt;0,9 ммоль/л, креатинфосфокиназа МВ &gt;82 ед/л, а также признаки продолжающейся ишемии миокарда при поступлении в виде рефрактерной/рецидивирующей боли в грудной клетке и/или одышки в сочетании как минимум с одним из прочих установленных критериев ОКСбпST очень высокого риска неблагоприятных ишемических событий согласно действующим клиническим рекомендациям. Наилучшие прогностические характеристики продемонстрировала модель на основе CatBoost (ROC-AUC=0,841). Хорошо интерпретируемая прогностическая модель ОКО на основе многофакторной логистической регрессии и полученных факторов риска имела схожие с моделью CatBoost метрики качества.</p></sec><sec><title>Заключение</title><p>Заключение. Комбинация клинических, лабораторных и эхокардиографических параметров позволяет эффективно прогнозировать наличие ОКО в когорте ОКСбпST. Разработанные модели машинного обучения демонстрируют диагностическую точность и могут стать основой для модификации алгоритмов ранней стратификации риска и оптимизации стратегий инвазивного лечения.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective. To develop a multivariate predictive model for the early detection of acute coronary occlusion (ACO) in patients with non-ST-elevation acute coronary syndrome (NSTE-ACS) using machine learning methods and a set of predictors available within the first hours of hospitalization.</p></sec><sec><title>Material and methods</title><p>Material and methods. This retrospective observational study included 1,144 patients diagnosed with non-ST-elevation myocardial infarction or unstable angina, hospitalized at a regional vascular center between 2019 and 2021. Invasive coronary angiography was performed in 900 patients, with ACO diagnosed in 64 (7.1%). To identify predictors of ACO, we analyzed 149 clinical, anamnestic, laboratory, and instrumental parameters, available during the initial hours of hospitalization. After selecting predictors, predictive models were developed using machine learning techniques: multivariate logistic regression (MLR), random forest, stochastic gradient boosting (XGBoost), and categorical boosting (CatBoost). Model performance was evaluated based on ROC-AUC, sensitivity (Sens), specificity (Spec), Precision-Recall AUC (PR-AUC), Brier-score, positive predictive value (PPV), negative predictive value (NPV), F1-score, and Accuracy.</p></sec><sec><title>Results</title><p>Results. Independent predictors of ACO included newly diagnosed or new left ventricular regional wall motion abnormalities, erythrocyte sedimentation rate &gt;15.5 mm/h, high-density lipoprotein cholesterol &lt;0.9 mmol/L, creatine phosphokinase MB &gt;82 U/L, and signs of ongoing myocardial ischaemia at admission: refractory or recurrent chest pain and/or dyspnea, combined with at least one other established criterion of very high-risk NSTE-ACS according to current clinical guidelines. The CatBoost-based model demonstrated the best prognostic performance (ROC-AUC = 0.841). A highly interpretable prognostic model based on multivariable logistic regression, using the identified risk factors, had performance metrics comparable to the CatBoost model.</p></sec><sec><title>Conclusion</title><p>Conclusion. The combination of clinical, laboratory, and echocardiographic parameters enables effective prediction of ACO in the NSTE-ACS cohort. The developed machine learning models demonstrate diagnostic accuracy and can form the basis for modifying early risk stratification algorithms and optimizing invasive treatment strategies.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>острый коронарный синдром без подъема сегмента ST</kwd><kwd>инвазивная коронарная ангиография</kwd><kwd>чрескожное коронарное вмешательство</kwd><kwd>острая коронарная окклюзия</kwd><kwd>машинное обучение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>non-ST-elevation acute coronary syndrome</kwd><kwd>invasive coronary angiography</kwd><kwd>percutaneous coronary intervention</kwd><kwd>acute coronary occlusion</kwd><kwd>machine learning</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование поддержано Госзаданием по теме поискового научного исследования НИИ кардиологии Томского НИМЦ “Разработка и валидация технологий диагностики, лечения и профилактики сердечно-сосудистых заболеваний на основе анализа медицинских изображений и больших структурированных данных” №126022417812-2 (постановка задачи, сбор данных, оценка и интерпретация результатов) и Госзаданием Дальневосточного федерального университета: проект FZNS-2026-0014 (дизайн исследования и разработка моделей).</funding-statement><funding-statement xml:lang="en">This study was supported by the State Assignment for the research project of the Cardiology Research Institute, Tomsk National Medical Research Center "Development and Validation of Technologies for the Diagnosis, Treatment, and Prevention of Cardiovascular Diseases Based on the Analysis of Medical Images and Big Structured Data" № 126022417812-2 (problem statement, data collection, evaluation, and interpretation of results) and the State Assignment of the Far Eastern Federal University: Project FZNS-2026-0014 (research design and model development).</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">Martin SS, Aday AW, Allen NB, et al.; American Heart Association Council on Epidemiology and Prevention Statistics Committee and Stroke Statistics Committee. 2025 Heart Disease and Stroke Statistics: A Report of US and Global Data From the American Heart Association.
