Mild or moderate chronic obstructive pulmonary disease risk in elective coronary artery bypass grafting surgery.

A history of chronic obstructive pulmonary disease (COPD) is considered a risk factor in patients undergoing coronary artery bypass grafting (CABG) surgery. The objective of this study was to examine the impact of history of mild or moderate COPD on outcome in patients undergoing elective CABG surgery. In this prospective, case-controlled study, we compared two groups of adult patients undergoing elective CABG surgery. In this prospective, case-controlled study, we compared two groups of adult patients undergoing elective CABG surgery. There were no statistically significant differences regarding early postoperative complications between the groups (p > 0.05). The median duration of mechanical ventilation and ICU length of stay were 0.4 and 1 days, respectively, in the two groups. The mean (+/- SD) hospital stay was 7.8 +/- 1.6 days in the COPD group and 7.5 +/- 1.3 days in the control group (p = 0.1). The mortality rate was found 1.4% in COPD patients and 0.7% in the control group (p = 0.5). We concluded that patients with a history of mild or moderate COPD undergoing elective CABG had morbidity and mortality rates comparable with those of controls (p > 0.05).
