Introduction. Despite the decrease in activity and the trend towards the end of the pandemic of a new coronovirus infection (NCI), the burden of NCI remains a serious problem of modern healthcare. Since the beginning of the NCI pandemic, evidence has been obtained that the long-term consequences of COVID-19 infection for patients with cardiovascular pathology will be characterized by an unfavorable prognosis. The ability to predict complications in the early and late postoperative period after CABG for patients after CCI is an important tool to influence the prognosis. Materials and methods. We examined 60 patients with various forms of coronary artery disease who were selected for CABG. The first group consisted of 30 patients who had previously undergone NCI. The second group consisted of 30 persons without NCI in history. The groups were comparable in terms of gender (21 men (70%) in the first group and 25 (83.3%) men in the second, p=0.2) and age (mean age 64.4±1.1 years in the first group and 63.3±1.04 in the second, p=0.46). In all patients, except for standard laboratory and instrumental diagnostic methods, Echo-KG parameters, EuroScore and Syntax index, the frequency of concomitant diseases and postoperative complications were evaluated. Statistical analysis was carried out using the Microsoft Excel 2017 program, the calculation of the significance of differences (p) was carried out using the Fisher test. Results: Most patients of both groups had AH (29 each (96.6%), p=0.4), CHF was observed in 7 (23.3%) persons of the first group and 6 (20%) of the second (p=0, 47). The Syntax SCORE index was initially statistically significantly higher in patients of the first group than in the second - 25.55 ps 21.62 (p=0.03). DM was somewhat more common in patients of the first group than in the second (15 (50% ps 9 (30%, p=0.13). 0.87 hours, p = 0.008. In 5 (16.6%) patients of the first group, the postoperative period was complicated by major bleeding, in the second group, this complication had 2 (6.6%) patients p = 0.28. In most patients of both groups in the postoperative period, hydrothorax was diagnosed (25 (83.3% of persons of the first group and 24 (80%) of the second, p = 0.4), four patients of the first group (13.3%) had hydropericardium, in the second group of similar cases not noted, p=0.04).Atrial fibrillation was observed in more patients of the first group than the second - 11 (36.6%) ps 6 (20%), p=0.19.12 months after the surgical treatment An analysis of late complications of surgery was carried out.There were no differences between the groups in the frequency of newly emerging angina pectoris (5 patients in each group (16.6%)). Clinical CHF was more often observed in patients of the first group — 16 (53.3%) than in the second — 11 (36.6%) p=0.19. Atrial fibrillation was more common in patients of the first group — 4 (13.3%) ps 2 (6.6%) (p=0.67). The high frequency of detection of oncological diseases in patients after undergoing NCI is cause for concern - 5 (16.6%); in patients of the second group, oncological diseases were not diagnosed (p=0.05). Conclusion: Thus, patients with NCI were more likely to have diabetes, bleeding in the perioperative period, they had a longer duration of EC. The late postoperative period for this group of patients was characterized by a higher incidence of cardiac arrhythmias, a higher incidence of CHF, and a rather high (compared with the group after CABG without a history of NCI) incidence of newly diagnosed oncological diseases. The data obtained indicate a higher risk of late perioperative complications after CABG in patients after CCI, which emphasizes the need for more detailed preparation of this category of patients and the development of individual follow-up follow-up programs, as well as more in-depth oncological screening.
