BACKGROUND: Limited data is available to guide operators as to the optimal revascularisation strategy in patients with previous CABG representing with angina. METHOD: Retrospective analysis of 161 patients with prior CABG undergoing PCI in two centres between September 2005 and April 2008. RESULTS: 161 patients (132 male, 68 ± 8 years) underwent PCI at 126 ± 65 months after index CABG. Clinical presentation of recurrent ischaemia was stable in 59.7% and as an acute coronary syndrome in 40.3% of patients. Mean follow-up after PCI was 13.5 ± 4.8 months. About 62.7% of patients underwent native vessel PCI, 32.9% had a graft only PCI, and 4.4% having a combination of both. Drug eluting stents were used in 84.9% of cases. There was one cardiac death and one case of redo CABG during follow-up. Mean CCS angina class decreased from 2.87 to 0.67 (P < 0.0001) in the follow-up group. About 13.6 % of all patients had a MACE at follow up. This was higher in the graft PCI group (21.6% vs. 8.9%, P = 0.048). About 12.4% of the total cohort underwent repeat PCI although 30% of these required PCI for a de-novo lesion. TVR rate was significantly higher in patients undergoing graft PCI than native vessel PCI (15% vs. 4.9%, P = 0.031). Graft PCI was an independent predictor (HR 3.73, 1.27-10.87 [95%CI], P = 0.016) of MACE in these patients. CONCLUSION: PCI significantly improved angina in these patients with low overall rates of TVR. However TVR rate was significantly higher in patients undergoing graft PCI than those undergoing native vessel PCI.
