Intracranial Arterial Stenosis
Conditions
Brief summary
1. It is a multicenter, open-label, sing arm study to evaluate the effects of treatment of Rosuvastatin 10-20mg in volume and morphology of atherosclerotic plague by reducing LDL-C level to or less than 70mg/dl. 2. Ischemic stroke patients will be enrolled within 1 month after stroke onset. 3. Patients will be visited at 0m, 1m, 3m, 6m, 9m, 12m, 18m and 24m.
Interventions
DRUGRosuvastatin
Rosuvastatin, 10mg for 4-weeks, then according to the results of the LDL-C, adjust dose of rosuvastatin, maximum to 20 mg/d, to reduce LDL-C under 70 mg/dl for two years.
