【Abstract】 Hyperhomocysteina is an indepentent risk factor of cardiovascular disease.Folic acid supplementation can lower plasma tHey concentrations safely and inexpensively.However,until recently there has been uncertainty regarding the optimum vitamin dosage compounding plan for lowering homocysteine concentrations. Recently an alternative hypothesis is that a low blood folate concentration is a risk factor for cardiovascular disease independent of plasma homocysteine concentration.This would indicate that a dificiency in folate rather than hyperhomocysteinamia,may be the actual risk factor.It remains to be established wberther normalizing elevated plasma tHey by supplementing B-Vitamins will influence cardiovascular mortality and morbility.更多还原
