Impact of Diabetes on Graft Patency and Progression of Proximal Coronary Stenosis After Coronary Bypass Surgery

Key Points

• This research examines how diabetes affects the patency of grafts and the progression of coronary artery stenosis after bypass surgery.
• Analyzed graft patency rates in patients with diabetes post-coronary bypass surgery.
• Compared the progression of proximal stenosis in saphenous vein grafts and arterial grafts.
• Diabetes did not affect overall graft patency rates.
• Diabetes was linked to faster progression of proximal stenosis in grafted areas.
• Saphenous vein grafts showed a decline in patency, increasing myocardial ischaemia risk, while arterial grafts maintained better patency.
