Brief Summary

To observe the safety and efficacy of intensive drug therapy for ischemic stroke patients.Patients with acute stroke caused by intracranial arterial stenosis (stenosis rate ≥70%) were enrolled and accept dual antiplatelet therapy (DAPT) (aspirin 100 mg/d and clopidogrel 75 mg/d for 90 days, followed by aspirin 100 mg/d for long term) under the guidance of platelet function analysis (Verifynow) combined with the intensive statin therapy (40 mg/d for 14 days, followed by 20 mg/d for long term).

Study Population

Patients with acute stroke caused by intracranial arterial stenosis (stenosis rate ≥70%)

You may qualify if:

  • Age between 35 and 80 years;
  • Onset \<72 hours;
  • New-onset ischemic stroke confirmed by skull magnetic resonance diffusion weighted imaging (MR-DWI);
  • Severe ICAS (stenosis ≥70%) indicated by time-of-flight magnetic resonance angiography (TOF-MRA).

You may not qualify if:

  • Ischemic stroke caused by other etiological factors (e.g., cardio-embolism, arterial dissection, vasculitis, etc.);
  • Post-infarction hemorrhagic transformation and intraplaque hemorrhage as indicated by imaging examination;
  • Contraindications to aspirin, clopidogrel, or atorvastatin;
  • Intracranial hemorrhage within 3 months and a recent history of surgery or trauma;
  • Severe organ impairment, liver insufficiency, and renal insufficiency;
  • Complicated with tumors or hemorrhagic diseases;
  • Use of drugs forbidden to use in combination after onset, including other antiplatelet drugs, anticoagulants, thrombolytic drugs, and drugs affecting antiplatelet agents and statin metabolism.
