title: Combined coronary artery bypass grafting and abdominal aortic aneurysm repair.
abstract: BACKGROUND
  We report here the results of combined coronary artery bypass grafting (CABG) and abdominal aortic aneurysm (AAA) repair and the factors associated with higher mortality following this procedure.
  
  
  METHODS
  The authors performed a retrospective chart review of 26 patients who underwent combined CABG and AAA repair between March 1990 and October 1996.
  
  
  RESULTS
  No postoperative myocardial infarction or major cardiac complications were noted. A morbidity rate of 38% (n = 10) and mortality rate of 11% (n = 3) were noted. Comparative analysis of nonsurvivors (n = 3) versus survivors (n = 23) revealed the following: ejection fraction (EF) was significantly lower (33% +/- 3% versus 44% +/- 14%, P < 0.05), duration of cardiopulmonary bypass (CPB) was significantly longer (239 +/- 122 minutes versus 141 +/- 54 minutes, P < 0.05), and incidence of postoperative respiratory failure (67% versus 17%, P = 0.001) were significantly higher in nonsurvivors. No differences in mean age, gender distribution, incidence of hypertension or diabetes were noted between the groups.
  
  
  CONCLUSIONS
  Combined CABG and AAA repair protected patients from postoperative aneurysm rupture and myocardial infarction. Poor EF, prolonged CPB, and postoperative respiratory failure were associated with higher mortality.
