Своевременная диагностика позволяет снизить частоту осложнений и уменьшить нагрузку на систему здравоохранения. Однако традиционные методы остаются дорогими, инвазивными и ограниченно доступными. Недавние исследования подтверждают перспективность применения методов машинного обучения в клинической практике. В этой связи возникает вопрос: можно ли достоверно прогнозировать наличие заболевания, используя только клинико-демографические данные, без визуализационных методов?Целью данной работы было оценить точность и практическую ценность таких моделей. На объединённом протоколе данных UCI Heart Disease (n = 920) был обучен алгоритм LightGBM, который показал следующие результаты: accuracy = 0.8696, precision = 0.8679, recall = 0.9020, F1-score = 0.8846. Полученные данные дополняют результаты предыдущих исследований, основанных на визуализации.Исследование включало сравнение нескольких алгоритмов при единых условиях предварительной обработки и валидации, проверку калибровки вероятностей и интерпретацию с помощью метода SHAP. Анализ показал, что ключевые предикторы (например, депрессия STсегмента) согласуются с клиническими знаниями. Это подтверждает возможность применения модели для первичного скрининга и направления на дополнительную диагностику. В целом, калиброванные и интерпретируемые алгоритмы на основе открытых клинических данных могут стать ценным инструментом маршрутизации пациентов в условиях ограниченных ресурсов.</p></abstract><trans-abstract xml:lang="en"><p>Coronary artery disease remains one of the leading causes of death and disability worldwide. Timely diagnosis can reduce the incidence of complications and ease the burden on healthcare systems. However, traditional methods are often costly, invasive, and limited in accessibility. Recent studies confirm the potential of machine learning for clinical applications. This raises the question: is it possible to reliably predict the presence of disease using only clinical and demographic data, without imaging methods?The aim of this study was to evaluate the accuracy and practical value of such models. Using the UCI Heart Disease dataset (n = 920) under a unified protocol, the LightGBM algorithm was trained and achieved the following results: accuracy = 0.8696, precision = 0.8679, recall = 0.9020, F1-score = 0.8846. These findings complement previous research based on imaging approaches.The study compared multiple algorithms under identical preprocessing and validation conditions, assessed probability calibration, and applied SHAP for interpretability. The analysis revealed that the main predictors (e.g., ST-segment depression) aligned with established clinical knowledge. This confirms that the model can be used for initial screening and referral to additional diagnostics. Overall, calibrated and interpretable algorithms based on open clinical data can serve as a valuable tool for patient routing in resourcelimited settings.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>коронарная болезнь сердца (КБС)</kwd><kwd>машинное обучение</kwd><kwd>LightGBM</kwd><kwd>классификация</kwd><kwd>клинико-демографические данные</kwd><kwd>стратификация риска</kwd><kwd>интерпретация SHAP</kwd><kwd>ROC–AUC</kwd><kwd>калибровка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>coronary heart disease (CHD)</kwd><kwd>machine learning</kwd><kwd>LightGBM</kwd><kwd>classification</kwd><kwd>clinical and demographic data</kwd><kwd>risk stratification</kwd><kwd>SHAP interpretation</kwd><kwd>ROC–AUC</kwd><kwd>calibration</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">Reducing the Global Burden of Cardiovascular Disease, Part 1: The Epidemiology and Risk Factors / Р.
