CME Paper: Homocysteine: The New Risk Factor for Cardiovascular Disease in the Elderly.
Higher levels of plasma homocysteine are associated with a variety of atherosclerotic conditions that are particularly pertinent to elderly persons. Cross sectional data have suggested that the lower deciles of plasma and dietary folate are highly associated with the presence of carotid stenosis in the elderly. Recent prospective studies have demonstrated strong associations between elevated concentrations of homocysteine and the incidence of cardiovascular mortality, total mortality, and stroke in elderly men and women. The impact of folate fortification on homocysteine levels has been assessed in middle-aged adults, but the clinical impact of fortification or supplementation of the diet with folate on clinical end points of cardiovascular disease is presently unknown, although clinical trials with folate supplementation are underway.
