Long-term clinical and angiographic outcomes in patients with diabetes undergoing coronary artery bypass graft surgery: Results from the PRoject of Ex-vivo Vein graft ENgineering via Transfection IV Trial

Patients with diabetes had similar rates of vein graft failure but worse clinical outcomes than patients without diabetes. Patients who received insulin had significantly worse clinical outcomes than patients who did not receive insulin. Further studies to better understand the mechanism behind these findings and to improve the outcomes of patients with insulin-requiring diabetes undergoing CABG surgery are warranted.
