| Current Primary Outcome Measures |
Recurrent stroke in the territory of the symptomatic artery [ Time Frame: 1 year ] Time to ischemic stroke in the territory of the symptomatic artery. Stroke is ascertained by the site neurologist and defined as new or worsening symptoms lasting >24 hours and associated with imaging evidence of ischemia on CT or MRI in the distribution of the stenotic artery.

| Brief Summary | The objective of this study is to determine the mechanisms of stroke in patients with Intracranial Atherosclerotic Disease (IAD) by specifically evaluating limitations of antegrade flow through the stenotic artery, distal tissue perfusion to the affected territory, and artery-to-artery embolism. The hypothesis is that non-invasive imaging biomarkers that stratify stroke risk and distinguish mechanisms of IAD. This prospective multicenter study will enroll 175 patients with recently symptomatic high-grade IAD. Patients will be studied within 21 days of the index event (allowing appropriate time to arrange for diverse imaging modalities), with the following advanced neuroimaging techniques to elucidate mechanisms of recurrent ischemia:
Patients will receive standardized medical management and its effectiveness on blood pressure, lipid, and glycemic control will be monitored. The primary outcome is recurrent stroke in the territory of the stenotic artery during a 1-year follow-up period; secondary outcomes are: a) new asymptomatic ischemic lesions on MRI in the distribution of the stenotic artery at 6-8 weeks, and b) transient ischemic attack (TIA) in the distribution of the stenotic artery during a 1-year follow-up period. Patients will be recruited at various sites that will be trained and certified on the imaging techniques employed. Raw imaging data will be interpreted centrally. |
