The outcomes of coronary artery bypass grafting (CABG) surgery are determined by numerous factors. This study aimed to analyze the factors contributing to short-term outcomes of patients undergoing isolated CABG. This retrospective analysis enrolled all adult patients undergoing isolated CABG at our center between January 2013 and December 2016. Clinical characteristics and postoperative events were recorded and analyzed. Overall, 242 patients (mean age, 59.7 ± 9.5 years) were included. The majority of the patients (88.4%) were men. The median left ventricular ejection fraction (LVEF) was 50% ± 15%, with 38% patients having an LVEF lower than 40% and 9.1% having an LVEF lower than 25%. The mean preoperative creatinine level was 1.25 ± 0.73, and the estimated glomerular filtration rate was 68.55 ± 23 ml/min/1.73 m2. The intensive cardiac care unit stay and total in-hospital stay were 70 ± 59 h and 8 ± 4 days, respectively. The in-hospital mortality rate was 2.1%. The most common major adverse events were new-onset atrial fibrillation (31.8%) and significant worsening of renal function (21.5%). Stroke occurred in 3.7% patients, for which preexisting chronic kidney disease (CKD) and dyslipidemia were strong predictors (P < 0.05; area under the curve [AUC], 87.7%). Advanced age and hypertension were considered significant risk factors for developing new-onset atrial fibrillation (P < 0.05; AUC 65%). Worsening renal function and new-onset atrial fibrillation were the most frequent complications that occurred during hospitalization following CABG. Preexisting CKD and dyslipidemia were the major risk factors for developing acute stroke post surgery.
