Epidemiological studies suggest that elevated homocysteine is linked to stroke and heart disease. However, the results of lowering homocysteine levels in reducing the risk of stroke recurrence are controversial. Aims The study aims to evaluate whether homocysteine-lowering therapy with folic acid and vitamins B 6 and B 12 reduces recurrent stroke events and other combined incidence of recurrent vascular events and vascular death in ischemic stroke patients of low folate regions. Design This is a multicenter, randomized, double-blinded, placebo-controlled trial. Patients ( n = 8000, α = 0·05, β = 0·10) within one-month of ischemic stroke (large-artery atherosclerosis or small-vessel occlusion) or hypertensive intracerebral haemorrhage with plasma homocysteine level ⩾15 μmol/l will be enrolled. Eligible patients will be randomized by a web-based, random allocation system to receive multivitamins (folic acid 0·8 mg, vitamin B 6 10 mg, and vitamin B12 500 μg) or matching placebo daily with a median follow-up of three-years. Study Outcomes Patients will be evaluated at six monthly intervals. The primary outcome event is the composite event ‘stroke, myocardial infarction, or death from any vascular cause’, whichever occurs first. Secondary outcome measures include nonvascular death, transient ischemic attack, depression, dementia, unstable angina, revascularization procedures of the coronary, and cerebral and peripheral circulations. Discussion This is the first multicenter randomized trial of secondary prevention for ischemic stroke in a Chinese population with a higher homocysteine level but without folate food fortification.
