Title: Multicenter Clinical Trial for Development of Guidelines of Adequate Blood Pressure Lowering in the Subacute Ischemic Stroke Patients Due to Intracranial Atherosclerosis
Brief Summary: To develop adequate blood pressure (BP) lowering strategy after subacute ischemic stroke patients with symptomatic severe intracranial atherosclerosis.

Primary hypothesis of this study is that aggressive BP control (lowering systolic BP between 110mmHg and 120mmHg) will not increase the ischemic lesion volumes in hemisphere compared to modest BP lowering (lowering systolic BP between 130mmHg and 140mmHg) in the patients with symptomatic severe intracranial atherosclerosis.
