L-arginine and tetrahydrobiopterin protects against ischemia/reperfusion-induced endothelial dysfunction in patients with type 2 diabetes mellitus and coronary artery disease.
Diminished levels of L-arginine and endothelial nitric oxide synthase (eNOS) uncoupling through deficiency of tetrahydrobiopterin (BH(4)) may contribute to endothelial dysfunction. We investigated the effect of L-arginine and BH(4) administration on ischemia-reperfusion (I/R)-induced endothelial dysfunction in patients with type 2 diabetes and coronary artery disease (CAD). Forearm blood flow was measured by venous occlusion plethysmography in 12 patients with type 2 diabetes or impaired gluc...Expand abstract
