Because 60% of patients who have an ischemic stroke have a recurrence within 2 years, physicians generally prescribe an anticoagulant, the most common being aspirin or warfarin. A large head-to-head study, reported at the May meeting of the American Academy of Neurology (AAN), shows that the two drugs perform equally well in reducing recurrence.
However, because warfarin is more difficult to prescribe and more expensive, the findings will result in the gradual abandonment of warfarin for these patients, said Vladimir Hachinski, MD, of the University of Western Ontario, London.
