Association between plasma asymmetrical dimethylarginine activity and saphenous vein graft disease in patients with coronary bypass.

BackgroundCoronary vein graft disease is an important contributor to the morbidity after coronary artery bypass graft surgery. Graft occlusion is a serious complication, which limits the use of the saphenous vein as a coronary bypass conduit. Asymmetrical dimethylarginine (ADMA) is an endogenous inh
