To determine whether vitamin supplements (folic acid 2 mg, B6 25 mg, B12 500 ug) reduce the risk of stroke, other serious vascular events, dementia and depression in patients with recent stroke or transient ischemic attacks of the brain or eye (TIA).

Official Title

VITATOPS: A Study of VITAmins TO Prevent Stroke

Conditions

– Stroke- Transient Ischemic Attack

Study Type

Interventional

Study Design

Prevention, Randomized, Double-Blind, Placebo Control, Parallel Assignment, Safety/Efficacy Study

Further Details

Background: Epidemiological studies suggest that raised plasma concentrations of total homocysteine (tHcy) may be a common, causal and treatable risk factor for atherothromboembolic ischemic stroke, dementia and depression. Although tHcy can be lowered effectively with small doses of folic acid, vitamin B12 and vitamin B6, it is not known whether lowering tHcy, by means of multivitamin therapy, can prevent stroke and other major atherothromboembolic vascular events, dementia and depression.

  • Primary outcome measure: Non-fatal stroke; non-fatal myocardial infarction; death due to vascular causes.
  • Secondary outcome measures: TIA; Revascularisation procedures; Dementia; Depression.

Conclusion: VITATOPS aims to recruit and follow up 8,000 patients between 2000 and 2006, and provide a reliable estimate of the safety and effectiveness of dietary supplementation with folic acid, vitamin B12, and vitamin B6 in reducing recurrent serious vascular events, dementia and depression among a wide range of patients with stroke and TIA.

Study Start

November 1998, Expected completion: June 2008
