Objective: Because percutaneous coronary intervention (PCI) has been performed excessively, many patients initially managed with PCI are being referred for coronary artery bypass grafting (CABG). The purpose of this study was to assess the impact of previous PCI on surgical mortality after off-pump CABG in diabetic patients with multivessel disease.Methods: Between January 2002 and April 2008, 595 consecutive patients (99.8% off-pump) had isolated CABG by one single surgeon. Of these, 274 patients with diabetes, mellitus and multivessel disease were retrospectively analyzed. Patients with previous PCI (n = 79) were compared with patients with no previous PCI (n = 196), and risk-adjusted impact of previous PCI on surgical mortality after CABG was determined using multivariate and propensity score analyses.Results: All patients underwent off-pump CABG without conversion to cardiopulmonary bypass during operation.
