Разработка и оценка эффективности моделей прогнозирования летального исхода после операции коронарного шунтирования, полученных с по­мощью методов машинного обучения на основании предоперационных данных.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В рамках когортного исследования проводилось ретроспективное прогнозирование вероятности госпитальной летальности после коронарного шунтирования (КШ) у 2182 больных со стабильной ишемической болезнью сердца. Пациенты были разделены на 2 выборки: обучающую (80%, n=1745) и тренировочную (20%, n=437). Исходное соотношение выживших (n=2153) и умерших (n=29) пациентов в общей выборке свидетельствовало о выраженном дисбалансе классов, для преодоления которого в тренировочной выборке был использован метод передискретизации. Для построения прогностических моделей риска использовали пять алгоритмов машинного обучения (МО): логистическая регрессия (Logistic regression), случайный лес (Random Forrest), CatBoost, LightGBM, XGBoost. Для каждого из данных алгоритмов на тренировочной выборке проводили кросс-валидацию и поиск гиперпараметров. В результате получили пять прогностических моделей с наилучшими параметрами. Полученные прогностические модели были применены к обучающей выборке, после чего сравнивалась их производительность с целью определения наиболее эффективной модели.</p></sec><sec><title>Результаты</title><p>Результаты. Прогностические модели, реализованные на ансамблевых классификаторах (CatBoost, LightGBM, XGBoost), демонстрировали лучшие результаты, в сравнении с моделями на основе логистической регрессии и случайного леса. Наилучшие метрики качества были получены для моделей на основе CatBoost и LightGBM (Precision — 0,667, Recall — 0,333, F1-мера — 0,444, ROC AUC — 0,666 для обеих моделей). Общими высокоранговыми параметрами для принятия решения об исходе для обеих моделей являлись: уровни креатинина и глюкозы крови, фракция выброса левого желудочка, возраст, критическое поражение (&gt;70%) каротидных артерий и магистральных артерий нижних конечностей.</p></sec><sec><title>Заключение</title><p>Заключение. Ансамблевые методы МО демонстрируют более высокие возможности прогнозирования исходов в сравнении с традиционными методами МО, например, логистической регрессией. Полученные в исследовании прогностические модели для дооперационного прогнозирования госпитальной летальности у больных, направляемых на КШ, могут служить основой для разработки систем поддержки принятия врачебных решений у больных ишемической болезнью сердца.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To develop and evaluate the effectiveness of models for predicting mortality after coronary bypass surgery, obtained using machine learning analysis of preoperative data.</p></sec><sec><title>Material and methods</title><p>Material and methods. As part of a cohort study, a retrospective prediction of in-hospital mortality after coronary artery bypass grafting (CABG) was performed in 2182 patients with stable coronary artery disease. Patients were divided into 2 following samples: learning (80%, n=1745) and training (20%, n=437). The initial ratio of surviving (n=2153) and deceased (n=29) patients in the total sample indicated a pronounced class imbalance, and therefore the resampling method was used in the training sample. Five machine learning (ML) algorithms were used to build predictive risk models: Logistic regression, Random Forrest, CatBoost, LightGBM, XGBoost. For each of these algorithms, cross-validation and hyperparameter search were performed on the training sample. As a result, five predictive models with the best parameters were obtained. The resulting predictive models were applied to the learning sample, after which their performance was compared in order to determine the most effective model.</p></sec><sec><title>Results</title><p>Results. Predictive models implemented on ensemble classifiers (CatBoost, LightGBM, XGBoost) showed better results compared to models based on logistic regression and random forest. The best quality metrics were obtained for CatBoost and LightGBM based models (Precision — 0,667, Recall — 0,333, F1-score — 0,444, ROC AUC — 0,666 for both models). There were following common high-ranking parameters for deciding on the outcome for both models: creatinine and blood glucose levels, left ventricular ejection fraction, age, critical stenosis (&gt;70%) of carotid arteries and main lower limb arteries.</p></sec><sec><title>Conclusion</title><p>Conclusion. Ensemble machine learning methods demonstrate higher predictive power compared to traditional methods such as logistic regression. The prognostic models obtained in the study for preoperative prediction of in-hospital mortality in patients referred for CABG can serve as a basis for developing systems to support medical decision-making in patients with coronary artery disease.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>методы машинного обучения</kwd><kwd>коронарное шунтирование</kwd><kwd>госпитальная летальность после коронарного шунтирования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>machine learning methods</kwd><kwd>coronary artery bypass grafting</kwd><kwd>inhospital mortality after coronary artery bypass grafting</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">Бокерия Л.
