Abstract

Background: Coronary artery bypass grafting (CABG) has become a safer procedure in recent years. Aims: We aimed to compare complications and early outcome of CABG in patients without history of general risk factors with those in patients with at least one general risk factor for coronary artery disease (CAD). Settings and Design: Cross-sectional study. Materials and Methods: Postoperative in-hospital complications, 30-day mortality rate and length of stay in hospital of 708 patients without preoperative general risk factors undergoing CABG in three university hospitals were assessed and compared with 10,844 patients undergoing CABG with at least one general risk factor as controls. In addition, the association of the studied variables with patients' early outcome was evaluated. Statistical Analysis: SPSS software with Pearson's χ2 test; independent sample t test, Mann-Whitney test and univariate analysis were used. Results: All studied in-hospital complications were similar between the two groups. Thirty days mortality rate (0.7% in study group and 1.4% in control group) was similar between groups, whereas prolonged length of stay (>12 days) was more frequent in control group (61.33% vs. 71.36%, P < 0.0001). Atrial fibrillation (P < 0.0001) was a strong predictor for prolonged length of stay in hospital. Conclusion: Most aspects of early complications after CABG, as well as 30-day mortality rate, were similar between patients with and without general risk factors for coronary artery disease undergoing CABG.
