PCI versus CABG in diabetic patients with chronic kidney disease [1]
In the FREEDOM trial, 1900 diabetic patients were randomized between coronary bypass surgery and percutaneous coronary intervention (PCI). Of these, 451 patients had chronic kidney disease (CKD) with a GFR 30-60 mL/min/1.73m2, and the remaining patients were categorized as having no CKD. In both groups, bypass surgery performed better over 5-year follow-up than PCI in patients with CKD (26.0% versus 35.6%; HR=0.73, 95% CI 0.50-1.05) and no CKD (16.2% verus 23.6%; HR=0.76, 95% CI 0.58-1.00). Therefore, independent of chronic kidney disease, diabetic patients with multivessel disease should undergo CABG.
