We studied changes in stroke prevention in 2000 ischaemic stroke patients using prospectively collected data from an incident stroke register over 3 years. Patients were divided into those with risk factors but no previous history of a vascular event (asymptomatic vascular disease) and those with risk factors and a previous history of stroke or TIAs, ischaemic heart disease, angina, myocardial infarction or peripheral vascular disease (symptomatic vascular disease). Time trends were analysed for the use of aspirin, management of hypertension and atrial fibrillation prior to the presenting episode. ⋯ The proportion of patients receiving antihypertensive treatment for symptomatic vascular disease was unchanged with time (66% to 64%) but there was a significant increase in the number of patients receiving antihypertensive treatment for asymptomatic vascular disease (28% to 44%) (p<0.05). The proportion of patients with atrial fibrillation receiving antithrombotic treatment did not increase for asymptomatic vascular disease (23% to 21%) (p=0.54) but did increase for symptomatic vascular disease (19.5% to 37%) (p<0.01) over 3 years. The use of warfarin in atrial fibrillation increased both in the case of asymptomatic (4.5% to 42%) (p<0.01) and symptomatic vascular disease (12.5% to 33.0%) (p<0.01).
