Abstract
OBJECTIVES This study aims to investigate the incidence and determinants of major early adverse events in low-risk patients undergoing isolated coronary artery bypass grafting (CABG). METHODS The multicentre E-CABG registry included 7352 consecutive patients who underwent isolated CABG from January 2015 to December 2016. Patients with an European System for Cardiac Operative Risk Evaluation (EuroSCORE) II of <2% and without any major comorbidity were the subjects of the present analysis. RESULTS Out of 2397 low-risk patients, 11 (0.46%) died during the index hospitalization or within 30 days from surgery. Five deaths were cardiac related, 4 of which were secondary to technical failures. We estimated that 8 out of 11 deaths were potentially preventable. Logistic regression model identified porcelain aorta [odds ratio (OR) 34.3, 95% confidence interval (CI) 1.3–346.3] and E-CABG bleeding grades 2–3 (OR 30.2, 95% CI 8.3–112.9) as independent predictors of hospital death. CONCLUSIONS Mortality and major complications, although infrequently, do occur even in low-risk patients undergoing CABG. Identification of modifiable causes of postoperative adverse events may be useful to develop preventative strategies to improve the quality of care of patients undergoing cardiac surgery.
