No increased early mortality with mild-moderate COPD before elective CABG; hypothesis-generating and requires prospective confirmation before practice change.
Case-Control
Does a history of mild or moderate COPD increase early postoperative complications and mortality in adult patients undergoing elective CABG surgery?
Absolute Event Rate: 1.4% vs 0.7%
p-value: p=0.5
A history of mild or moderate COPD does not significantly increase early postoperative morbidity or mortality in patients undergoing elective CABG surgery.
Michalopoulos et al. (2001) conducted a case-control in Elective coronary artery bypass grafting (CABG) surgery. History of mild or moderate COPD vs. Control group (no COPD) was evaluated on Mortality rate (p=0.5). A history of mild or moderate COPD in patients undergoing elective CABG surgery did not significantly increase mortality (1.4% vs 0.7%, p=0.5) compared to controls.
