Whether percutaneous coronary intervention (PCI) achieves similar outcomes remains unclear. Methods We performed a retrospective linkage study to determine outcomes in all patients undergoing coronary revascularisation for multi-vessel disease involving the left main stem or proximal left anterior descending coronary artery at the Royal Infirmary of Edinburgh over a 12-month period (2009–2010). The primary endpoint was a composite of death, myocardial infarction, stroke or readmission with heart failure at 12 months. Results Of 303 patients, 168 (55%) underwent CABG and 135 (45%) PCI. Patients undergoing PCI were older (68 ± 12 yrs vs 65 ± 10 yrs, p < 0.05), had less left main disease (30(22%) vs 75(45%), p < 0.001) and a greater updated Euroscore II (2.3 ± 2.3 vs 1.2 ± 1.1, p < 0.05), but similar Syntax scores (27 ± 12 vs 27 ± 10, p = ns) compared to patients undergoing CABG. Patients undergoing PCI received 2.4 ± 1.1 stents (65% drug-eluting) to treat 2.3 ± 0.8 vessels. Patients undergoing CABG received 2.1 ± 0.6 grafts (97% received an internal mammary graft). At 12 month follow-up, there was no difference in the primary endpoint, but mortality was lower in the PCI group (1(1%) vs 8(5%), p < 0.05). Following multivariate regression analysis, the presence of left main stem disease and a greater Euroscore II, but not mode of revascularisation, were predictive of the primary endpoint. Conclusions In this study of real-world practice, our findings suggest that PCI may be an acceptable alternative strategy to CABG in selected patients with high-risk coronary anatomy.
