title: [Correlation between previous coronary artery stenting and early mortality in patients undergoing coronary artery bypass graft surgery].
abstract: BACKGROUND
  In this study, we examine the effect of previous percutaneous intervention on the rate of adverse perioperative outcome in patients undergoing coronary artery bypass graft surgery (CABG).
  
  
  METHODS
  Outcomes of 240 CABG patients, collected consecutively in an observational study, were compared. Gp A (n=35) had prior PCI before CABG and Gp B (n=205) underwent primary CABG.
  
  
  RESULTS
  Statistically significant results were obtained for the following preoperative criteria: previous myocardial infarction: 48.6% vs 36.6% (P=0.003), distribution of CAD (P=0.0001), unstable angina: 45.7% vs 39% (P=0.04). For intraoperative data, the total number of established bypasses was 2.6 (GpA) vs 2.07 (Gp B) (P=0.017), with the number of arterial bypass grafts being: 20% vs 13% (P=ns). Regarding the postoperative course, no significant difference in troponine I rate, 24-hour bleeding: 962 ml (Gp A) vs 798 ml (Gp B) (P=0.004), transfusion (PRBC unit): 3.63 (Gp A) vs 2.5 (Gp B) (P=0.006). Previous PCI emerged as an independent predictor of postoperative in-hospital mortality (OR 2.24, 95% CI [1.52-2.75], P<0.01).
  
  
  CONCLUSIONS
  Patients with prior PCI presented for CABG with more severe CAD. Thirty-day mortality and morbidity were significantly higher in patients with prior PCI.
