artery of patients with coronary artery disease. However, the
combination was not more effective than vitamin C alone.
This finding suggests that in this setting, increased oxidative
stress may be an important mechanism for impaired endothelial
function. Combination of vitamins C and E may show beneficial
effects on graft patency due to improved vasomotor function
of the endothelium (as on radial artery or internal mammarian
artery conduits) in patients undergoing coronary artery surgery.
