Brief Summary

To observe the safety and efficacy of intensive drug therapy for ischemic stroke caused by severe intracranial arterial stenosis.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).

Conditions

Intensive Drug Therapy

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.
