Structural Properties of Coronary Artery Bypass

Recent studies have reported a high incidence of post-operative unfavorable cardiac-related events in pa-tients with diabetes who underwent coronary artery bypass grafting (CABG). Structural and functional char-acteristics of CABG conduits, which have been shown to play an important role in patient outcome after myocar-dial revascularization, have not been fully investigated in diabetic subjects. Therefore, we sought to determine the influence of adult-onset diabetes on vasoreactivity and morphological profile of venous and arterial grafts. Of the 160 consecutive patients enrolled in the study, 90 were diagnosed with type 2 diabetes and 70 did not have diabetes (control group). All patients underwent eval-uation of glucose control before surgery. Tissue speci-mens were collected from left internal thoracic arter
