Case-control, retrospective and prospective studies have identified a relationship between high plasma concentrations of homocysteine and vascular disease. The aim of the present review was to better understand the interrelation between plasma concentrations of homocysteine and vascular diseases, as well as the involvement of classical risk factors for the disease: genetic factors, such as mutations in the genes that codify the enzymes involved in […]
