Abstract

Homocysteine is an intermediate compound formed during the metabolism of methionine. Several studies have shown that plasma homocysteine concentrations rise with age. Overt or borderline deficiencies of folate, vitamin B12 or B6 and possibly age-related kidney dysfunction are the major causes of homocysteine elevation in the elderly population. Multiple case-control and prospective studies have shown that a high plasma homocysteine concentration is an independent risk factor for cardiovascular diseases; this association persists in the elderly. Supplementation with folic acid either alone or with vitamins B12 and B6 can lower plasma homocysteine. Intervention studies to assess the effects (if any) of such treatment on prognosis are now in progress in patients with vascular disease.
