Coronary artery bypass graft (CABG) surgery is the commonest type of heart operation performed. During this, arteries or veins (termed 'grafts') are used to supply blood around blockages within the blood vessels that supply the heart. Unfortunately, these grafts can sometimes fail, and patients can also experience complications like heart attacks and strokes, after surgery. It is known that vein grafts are more likely to narrow over time. Additionally, treating vein graft failure is very challenging, as repeat surgery is riskier and procedures to stent open the veins can also…
- : Cohort 1: Patients undergoing CABG surgery * Males and females over 18 years of age * Patients undergoing CABG surgery for multivessel coronary artery disease, who receive at least one saphenous vein graft Cohort 2: Patients with symptomatic saphenous vein graft vasculopathy * Males and females over 18 years of age * Patients who underwent CABG surgery ≥ 5 years prior to recruitment for multivessel disease and received 2 or more saphenous vein grafts * Referred for invasive coronary angiography due to recurrent symptoms and with a high suspicion of graft vasculopathy
