Detailed Description

In 2015, stroke was the second most frequent cause of death after coronary artery disease, accounting for 6.3 million deaths (11% of the total).Studies have reported a 30-day recurrence rate of 1.1 to 15 % after stroke and as high as 17% after transient ischemic attack .Therefore, early initiation of antiplatelet agents in ischemic stroke and patients is important to prevent stroke recurrence and is tracked as a quality measure by organizations that accredit stroke centers . Intravenous thrombolysis with alteplase is the mainstay medical treatment for acute ischemic stroke. given intravenously within 4.5 hours of symptom onset, to reopen occluded intracerebral arteries. As in fact most patients with ischemic stroke present to the emergency department beyond the approved time window for thrombolytic or other revascularization therapies beside their high cost and at this time, there are no approved urgent therapies for most of these patients In addition, those who present with rapidly resolving deficit or low National Institutes of Health stroke scale score are generally not considered for thrombolytic treatment, although approximately one third of them may be at high risk for neurological deterioration and recurrent vascular events.This study will evaluates the safety and efficacy of clopidogrel and aspirin in treatment of patients not eligible for recombinant tissue plasminogen activator or any other acute reperfusion therapy with acute ischemic stroke and transient ischemic attack within 24 hours of symptoms onset.
