The Role of Oxidative Stress in Modulation of the Relaxant Responses of Saphenous Vein and Internal Mammary Artery

Altered endothelial activity is enumerated amongst the leading causes of graft dysfunction following coronary artery bypass surgery and may account for differences in patency between arterial and venous grafts. This study investigates whether differences exist between basal endothelial functions of saphenous vein (SV) and internal mammary arteries (IMA) and explores the putative involvements of reactive oxygen species in this phenomenon. Basal...
