Scientific title
Study acronymVITATOPS
Study hypothesisTo determine whether the addition of vitamin supplement (folate 2 mg, B6 25 mg, B12 500 µg) to best medical/surgical management (including modification of risk factors) will reduce the combined incidence of recurrent vascular events (stroke, myocardial infraction) and vascular death in patients with recent stroke or transient ischaemic attach (TIA).

Secondary objectives:
1. To determine whether the addition of vitamin supplements (folate 2 mg, B6 25 mg, B12 500 µg) will reduce:

a) The incidence of revascularisation procedures of the coronary, cerebral and peripheral circulations

b) Incidence of dementia and depression in patient with recent stroke or TIA

c) Occurrence of TIA in patients with recent stroke or TIA

2. To determine whether the effect of adding vitamin supplements (folate 2 mg, B6 25 mg, B12 500 µg) on the incidence of the primary outcome event (stroke, MI or vascular death) is consistent in patient subgroups such as those of different ethnicity and genotype.
