Stroke is a common cause of disability. The most common type of stroke, an ischemic stroke, is caused by a blood vessel in the brain getting blocked by a clot. When this happens, part of the brain is damaged because it is not getting the blood supply it needs. To treat this type of stroke, doctors give medication and/or do a procedure to remove the blockage and restore blood supply to the brain. Unfortunately, patients who have had an ischemic stroke are at higher risk of having another ischemic stroke. This risk is highest in the first 21 days after a stroke. Currently, doctors give patients the medication aspirin every day, starting 24 hours after stroke treatment, to prevent recurrent strokes. However, some studies have shown that giving another medication, clopidogrel, in addition to aspirin, is safe and may work better than aspirin alone at preventing repeat strokes. Both aspirin and clopidogrel are a type of medication called an antiplatelet that prevents clots from forming in the blood. When both medications are given together, it is called dual antiplatelet treatment. The main risk of antiplatelet medications is bleeding. This research aims to study the safety and feasibility of using dual antiplatelet treatment to prevent recurrent strokes. Patients who have received treatment for an ischemic stroke will first be screened to rule out patients at high risk of bleeding. Following informed consent, patients at low risk of bleeding will be enrolled in the study 24 hours after their initial stroke treatment. Patients will be randomly assigned to either take aspirin alone or aspirin and clopidogrel for 21 days for recurrent stroke prevention. The study team will then follow patients for three months after treatment to collect information about their recovery and assess differences between the two groups.
