Brief Summary

A transient ischemic attack (TIA) is a transient episode of neurological dysfunction caused by focal brain, spinal cord, or retinal ischemia, without acute infarction. An ischemic stroke is a cerebral infarction. In POINT, eligibility is limited to brain TIAs and to minor ischemic strokes (with an NIH Stroke Scale \[NIHSS\] score less than or equal to 3). TIAs are common \[25\], and are often harbingers of disabling strokes. Approximately 250,000-350,000 TIAs are diagnosed each year in the US. Given median survival of more than 8 years \[32\], there are approximately 2.4 million TIA survivors. In a national survey, one in fifteen of those over 65 years old reported a history of TIA \[33\], which is equivalent to a prevalence of 2.3 million in older Americans. Based on the prevalence of undiagnosed transient neurological events, the true incidence of TIA may be twice as high as the rates of diagnosis \[33\]. Based on our review of the National Inpatient Sample for 1997-2003, there were an average of 200,000 hospital admissions for TIA each year, with annual charges climbing quickly in the period to $2.6 billion in 2003. Composite endpoint of new ischemic vascular events: ischemic stroke, myocardial infarction or ischemic vascular death at 90 days.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Neurological deficit (based on history or exam) attributed to focal brain ischemia and EITHER:
  • High risk TIA: Complete resolution of the deficit at the time of randomization AND ABCD2 score of (greater than or equal to) 4 OR
  • Minor ischemic stroke: residual deficit with NIHSS of (less than or equal to) 3 at the time of randomization
  • Ability to randomize within 12 hours of time last known free of new ischemic symptoms.
  • Head CT or MRI ruling out hemorrhage or other pathology, such as vascular malformation, tumor, or abscess, that could explain symptoms or contraindicate therapy.
  • Ability to tolerate aspirin at a does of 50-325 mg/day.

You may not qualify if:

  • Age \<18 years
  • TIA symptoms limited to isolated numbness, isolated visual changes, or isolated dizziness/vertigo.
  • In the judgment of the treating physician, a candidate for thrombolysis, endarterectomy or endovascular intervention, unless the subject declines both endarterectomy and endovascular intervention at the time of evaluation for eligibility.
  • Receipt of any intravenous or intra-arterial thrombolysis within 1 week prior to index event.
  • Gastrointestinal bleed or major surgery within 3 months prior to index event.
  • History of nontraumatic intracranial hemorrhage.
  • Clear indication for anticoagulation (e.g., warfarin, heparin) anticipated during the study period (atrial fibrillation, mechanical heart valve, deep venous thrombosis, pulmonary embolism, antiphospholipid antibody syndrome, hypercoagulable state).
  • Qualifying ischemic event induced by angiography or surgery.
  • Severe non-cardiovascular comorbidity with life expectancy \<3 months.
  • Contraindication to clopidogrel or aspirin.
  • Known allergy
  • Severe renal (serum creatinine \>2 mg/dL or 176.8umol/L) or hepatic insufficiency (prior or concurrent diagnosis, with International Normalized Ratio (INR)\>1.5 or any resultant complication, such as variceal bleeding, encephalopathy, or icterus)
  • Hemostatic disorder or systemic bleeding in the past 3 months
  • Current thrombocytopenia (platelet count \<100 x10\^9/l) or neutropenia (\<1 x10\^9/l)
  • History of drug-induced hematologic or hepatic abnormalities
  • +8 more criteria
