The study will be conducted over the next five years and will involve 50 sites across North America and 806 patients. Research will focus on preventing strokes in high-risk patients caused by clogged arteries in the brain, a condition known as intracranial arterial stenosis. We have only been enrolling patients since the 11th of February. Participants for the study will be selected from patients who have recently experienced a minor stroke and meet the eligibility requirements. These patients, after completing an informed consent, will be randomly selected to receive either aspirin or warfarin.
Intracranial disease is a lot more common then most people recognize.
We know that about 40,000 strokes per year are caused by this disease.
