Hyperhomocysteinaemia is considered to be an independent risk factor for vascular disease. Elevated plasma homocysteine may pose an oxidative stress, leading to the development of vascular damage. A component of this effect may be a disturbance of the extracellular aminothiol redox state. The relative contributions of plasma total homocysteine (tHcy) and plasma total cysteine (tCys) to the tota...
