血浆总半胱氨酸(tHcy)浓度升高与心血管事件风险大大增高有关。既往研究揭示,在多数非老年人个体,补充B族维生素能持续降低血浆tHcy水平,尤其是在同时伴高tHcy和低叶酸水平者。本文拟就补充B族维生素对降低老年人血浆tHcy的可能作用进行了分析。对象与方法本文为一随机双盲对照 Elevated plasma total cysteine ​​(tHcy) levels are associated with a significantly increased risk of cardiovascular events. Previous studies have revealed that in most non-elderly individuals, the addition of B vitamins can continue to reduce plasma tHcy levels, especially in patients with high tHcy and low folate levels. This article intends to add B vitamins on the elderly to reduce the plasma tHcy the possible role was analyzed. This article is a randomized double-blind control
