Abstract

The optimal coronary revascularization strategy for patients with diabetes and left main and/or multivessel disease is undetermined. The aim of our study was to evaluate percutaneous coronary intervention (PCI) versus coronary artery bypass graft (CABG) in those patients. We identified 13 articles, published before October 2011, enrolling 6992 patients, whose follow-up period ranged from 1 to 5 years. Patients with PCI had a significant reduction in cerebral vascular attack (CVA) (OR, 0.29; 95 % CI, 0.16-0.51; p < 0.0001, I (2) = 0 %) as compared with CABG, whereas there was a fourfold increased risk of repeat revascularization associated with PCI even using drug-eluting stent (OR, 4.44; 95 % CI, 3.42-5.78; Χ(2) = 4.92, p < 0.00001, I (2) = 0 %). The overall mortality (OR, 0.97; 95 % CI, 0.81-1.15; p = 0.70, I (2) = 0 %) was comparable between the PCI and CABG. However, in subgroup analysis, the composite outcome (death/myocardial infarction/CVA) was significantly reduced in favor of DES implantation (OR, 0.79; 95 % CI, 0.63-0.99; Χ(2) = 1.07, p = 0.04, I (2) = 0 %). Our study confirmed the cerebral vascular benefits of PCI by significantly reducing CVA risks, and the composite outcome was better in patients undergoing PCI with drug-eluting stent, despite a higher repeat revascularization rate. It poses imperative demands for future prospective randomized studies to define the optimal strategy in patients with diabetes and left main and/or multivessel disease.
