“…In addition, the study [ 9 ] found similar graft patency in patients with and without diabetes at 5-year angiographic follow-up. On the contrary, the study [ 10 ] found SV graft patency was 75% in patients with diabetes versus 84% in patients without diabetes ( P = .06) by at least 5 years of angiography follow-up. Ayan et al [ 11 ] found similar arterial graft patency in matched patients with and without diabetes, but worse SV graft patency in patients with diabetes.…”

This study aimed to examine the influence of diabetes on the left internal mammary artery (LIMA) and saphenous vein (SV) graft failure for 5-year follow-up. We enrolled 202 patients who underwent isolated off-pump coronary artery bypass grafting (CABG) surgery in 2014, angiographic follow-up occurred at 5 years after surgery. Angiographic outcomes in patients with or without diabetes were analyzed. Multivariate logistic regression analysis was used to identify independent predictors of graft dysfunction. A total of 66 (32.7%) patients had diabetes. Five-year rates of LIMA and SV graft failure were similar in patients with and without diabetes. In addition, in diabetics, the proportion of complete graft failure was significantly lower in the LIMA grafts (12/66, 18.2%) than in the SV grafts (57/133, 42.9%) (P = .001). In nondiabetic, the proportion of complete graft failure was also significantly lower in the LIMA grafts (28/136, 20.6%) than in the SV grafts (105/275, 38.2%) (P < .001). Multivariate logistic regression analysis showed that mean graft flow (MGF) was an independent predictor factor for LIMA (odds ratio = 1.186, 95% CI = 1.114–1.263, P < .001) and SV (odds ratio = 1.056, 95% CI = 1.035–1.077, P < .001) graft failure. Diabetes did not influence the patency of LIMA or SV grafts over a 5-year follow-up. LIMA grafts should be maximized in patients undergoing off-pump CABG surgery. Diabetes does not affect the patency of grafts CABG. Using angiography, our study proved that diabetes does not affect the patency of grafted vessels after CABG for 5 years.

“…[6,7] However, there still exists controversy on bypass graft patency in patients with versus without diabetes. [8][9][10][11][12] Therefore, in this study, we aim to elucidate the essential relationship between graft patency and diabetes in CABG patients.…”
