The materials for the study were medical documentation data obtained from 1,584 patients who underwent coronary artery bypass grafting in 2021–2024. The analysis was carried out on the basis of 24 preoperative signs and the fact of death in the early postoperative period. Spearman's correlation analysis was used in the statistical processing of the material, and the normality of the distribution of feature values was assessed using the Kolmogorov–Smirnov and CHI2 tests.</p></sec><sec><title>Results</title><p>Results. The IV functional class of angina pectoris, the EuroSCORE II value, the ejection fraction, the fact of unstable angina pectoris in the previous month, and pulmonary hypertension had an impact on the lethal outcome of surgery at a significance level &lt; 0.001. At the level of statistical significance &lt; 0.05, multifocal atherosclerosis, the fact and duration of myocardial infarction, and the functional class of chronic heart failure had an impact on death.</p></sec><sec><title>Conclusion</title><p>Conclusion. The research work provides information about the patient's risk factors that have the greatest and least impact on the development of death during surgery and in the early postoperative period. Since the correlation analysis did not reveal the prevailing interrelationships of individual signs, a regression analysis should be performed to further predict the fatal outcome.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Ишемическая болезнь сердца</kwd><kwd>Аортокоронарное шунтирование</kwd><kwd>Факторы риска</kwd><kwd>Летальный исход</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Coronary artery disease</kwd><kwd>Aortocoronary bypass surgery</kwd><kwd>Risk factors</kwd><kwd>And death</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Авторы заявляют об отсутствии финансирования исследования.</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">Харченко В.
