Clinical Analysis of the Results of Coronary Artery Bypass Grafting in Cancer Patients

Goal. To evaluate the clinical results of coronary artery bypass grafting (CABG) in patients with concomitant malignancies. Materials and methods. The retrospective study included 5 patients who were treated at the Dagestan Center for Cardiology and Cardiovascular Surgery from 2022 to 2025. All patients were diagnosed with malignant tumors (stomach, lung, thymus, sigmoid colon, bladder) in combination with severe coronary heart disease. Clinical and instrumental data, type of intervention, postoperative outcomes, and oncological tactics were analyzed. Results. Three patients underwent CABG using an artificial circulatory system, and two had surgery without a pump. In four cases, a stable course of the postoperative period was achieved and oncological treatment was continued; one patient died from a pulmonary complication. There were no cases of tumor recurrence, myocardial infarction, or severe arrhythmias during the follow-up period. Conclusions. CABG in cancer patients can be an effective stage in complex treatment, subject to careful selection, prognosis assessment, and team management.
