Abstract

Aim. To detect the perioperative insult predictors in patients with isolated coronary artery bypass grafting. Materials and methods. At Perm Federal Center of Cardiovascular Surgery, 2823 coronary artery bypass graft surgeries were performed over the period from January 2013 to December 2014. Results. The total hospital lethality among patients with isolated coronary artery bypass grafting was 1,2 % (36). Perioperative acute stroke (AS) was revealed in 32 (1,1 %) patients. To carry out the analysis, we divided patients into 2 groups: group A - 32 patients with AS diagnosed in the postoperative period, and group B - 2791 patients without severe cerebrovascular disorders. The analysis showed that in group A, there were significantly more female patients - 13 (40,6 %) versus 543 (19,5 %) in group B ( p < 0,01) as well as patients over 60: 21 (65,6 %) and 1251 (44,8 %), respectively ( p < 0,05); over 70: 9 (2,1 %) and 348 (12,5 %) patients, respectively ( p < 0,05). In group B, the number of patients with rhythm disturbance by atrial filbrillation type was 244 (8,7 %), in group A - 7 (21,9 %), that is reliably higher ( p < 0,01). In AS group, diabetes mellitus was found in 12 (37,5 %) patients, in group without AS - in 212 (7,6 %) ( p < 0,01). Significant differences were obtained by the quantity of patients with brachiocephalic artery atherosclerosis - 17 (53,1 %) in group A and 624 (22,4 %) in group B ( p < 0,01), patients with low extremity artery atherosclerosis - 16 (50,0 %) and 715 (25,6 %), respectively ( p < 0,01). Conclusions. The most significant predictors influencing the risk for occurring perioperative insult are concomitant brachiocephalic artery atherosclerosis, low extremity artery atherosclerosis, rhythm disturbance by atrial filbrillation type, diabetes mellitus, middle age.
