The Bypass Angioplasty Revascularization Investigation (BARI) was designed to compare CAGB and PTCA for patients with symptomatic multivessel coronary artery disease. The randomized trial reported significant differences in 7-year survival favouring CABG. However, for the 353 patients with treated diabetes mellitus, an overwhelming benefit associated with CABG was seen (mortality: 23.6% CABG vs 44. 3% PTCA, p=0.0011), whilst no treatment difference was observed for the 1476 non-diabetic patients (13.6% CABG vs 13.2% PTCA, p=0.72). Patients assigned to PTCA experienced fewer in-hospital Q-wave MIs, but these patients received more revascularization procedures and more often had angina during follow-up.
