Role of Anti-platelet in Treatment of Acute Ischemic Stroke
Role of Anti-platelet in Treatment of Acute Ischemic Stroke
Role of anti-platelet in treatment of acute ischemic stroke to determine the safety of
 immediate anti-platelet therapy .that is started as soon as possible within the first 24
 hours of the onset of symptoms.
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.
Inclusion Criteria:

 1. Age of the patients is 40 years or older.

 2. Patients not eligible for recombinant tissue plasminogen activator or any other acute
 reperfusion therapy presenting after 6hours of onset of symptoms.

 3. Patients presented with clinical symptoms of acute stroke or TIA with onset less than
 24 hours before starting any treatment.

 4. The diagnosis of stroke or TIA basing on clinical examination using National Institute
 of Health stroke scale (NIHSS) by a stroke specialist

 Exclusion Criteria:

 1. Any history of ICH or systemic hemorrhage.

 2. Any evidence of hemorrhage on baseline CT brain imaging.

 3. Patients presented with failed medical or surgical thrombectomy.

 4. International normalized ratio (INR) more than 1.5.

 5. History of allergy to aspirin or clopidogrel or both of them.

 6. Platelets count less than 100,000/mm3.

 7. Hematocrit less than 30 mg/dL .

 8. glucose less than 50 mg/dL or greater than 400 mg/dL.to exclude hypoglycemia induced
 focal neurological deficit.
