Background: Hyperhomocysteinemia is an important cardiovascular risk indicator in the oldest old and is also associated with elevated arterial stiffness in this age group. Several intervention trials reported a lack of benefit of B-vitamin supplementation on cardiovascular outcomes, therefore we aimed to investigate the effect of B-vitamin supplementation on arterial stiffness and cardiovascular events in hyperhomocysteinemic elderly subjects.

Methods and Results: The B-PROOF study is a double-blind randomized-controlled trial, including 2919 elderly (≥ 65 years), with hyperhomocysteinemia (12–50 μmol/l), treated with B-vitamins (500 μg vitamin B12 and 400 μg folic acid) or placebo for 2 years. In a subgroup (n = 569) the effect of B-vitamins on pulse wave velocity (PWV) was investigated. In the total B-PROOF population, incidents of cardiovascular and cerebrovascular events were determined via structured questionnaires and also blood pressure was measured. Compared to placebo, B-vitamins lowered serum homocysteine by 3.6 μmol/L (p<0.001). Analysis of covariance showed no effect of B-vitamins supplementation on PWV levels, but aortic pulse pressure was higher in the intervention than in the placebo group (49.6 mmHg vs. 47.2 mmHg; p =0.02). Furthermore, a significant reduction of cerebrovascular events in females (OR 0.33 95%CI [0.15 ; 0.71]), but not in males was observed.

Conclusions: B-vitamins supplementation in hyperhomocysteinemic elderly has no effect on PWV and caused a modest increase in aortic pressure, but also a reduction in cerebrovascular events in females. Arterial stiffness is not likely to be the underlying pathway of the negative trial outcomes.
