Our data show a heterogeneous prognosis and high mortality even for long-time survivors of ischaemic stroke at a young age. Prospective studies of young stroke patients and controls are necessary for direct comparison.
What is the role of dual antiplatelet therapy after high risk transient ischaemic attack or minor stroke? Specifically, does dual antiplatelet therapy with a combination of aspirin and clopidogrel lead to a greater reduction in recurrent stroke and death over the use of aspirin alone when given in the first 24 hours after a high risk transient ischaemic attack or minor ischaemic stroke? An expert panel produced a strong recommendation for initiating dual antiplatelet therapy within 24 hours of the onset of symptoms, and for continuing it for 10-21 days. Current practice is typically to use a single drug
Background and Purpose—
The Scandinavian Candesartan Acute Stroke Trial (SCAST) found no benefits of blood pressure–lowering treatment with candesartan in acute stroke. We have investigated whether the effect of treatment is different in different subtypes of ischemic stroke.
Methods—
SCAST was a randomized- and placebo-controlled trial of candesartan in 2029 patients presenting within 30 hours of ischemic or hemorrhagic stroke and systolic blood pressure ≥140 mm Hg. Ischemic stroke subtype was categorized by the Oxfordshire Community Stroke Project classification. There were 2 primary effect variables: the composite vascular end point of vascular death, myocardial infarction, or stroke during the first 6 months and functional outcome at 6 months.
Results—
A total of 1733 patients with ischemic stroke were included: total anterior circulation infarcts in 129, partial anterior in 850, posterior in 236, and lacunar in 510 patients. For functional outcome there was a significant trend toward a better effect of candesartan in patients with larger infarcts (total anterior circulation or partial anterior circulation) than in patients with smaller infarcts (lacunar infarction;
P
=0.02). For the composite vascular end point, there were no differences in treatment effect.
Conclusions—
The results suggest that the effect of blood pressure–lowering treatment with candesartan may differ according to different types of acute ischemic stroke, but this needs to be confirmed in future trials.
