Many studies mainly from Euro-American population with a focus on extracranial carotid plaque have fully demonstrated the advantages of intensive statin therapy on stabilizing or reversing plaque burden, reversing plaque composition presenting that lipid-rich necrotic core (LRNC) is gradually replaced by fibrous tissue, and even reversing pattern of arterial remodeling to reduce the occurrence of cerebrovascular events. Yet, direct evidence of the effect of intensive statin therapy on intracranial atherosclerotic plaques is lacking and the effect of statin intensity and duration on intracranial plaque burden and composition is still unclear. High resolution magnetic resonance imaging (HRMRI) is a new and non-invasive technique that enable to assess the morphologic characteristics of vascular wall and plaque composition of intracranial artery. Based on above discussion, the investigators conduct this study to further determine the effect of intensive statin in ischemic stroke with intracranial atherosclerotic plaques.",[28,29],"Stroke, Ischemic","Atherosclerosis, Cerebral","RECRUITING","2026-04-22",{"date":33,"type":34},"2026-04-27","ACTUAL",{"date":36,"type":34},"2018-12-01",{"date":38,"type":22},"2027-11-30",{"name":40,"class":41},"General Hospital of Shenyang Military Region","OTHER",1,{"id":44,"slug":45,"hasResults":11,"nctId":46,"briefTitle":47,"officialTitle":47,"acronym":4,"eligibilityCriteria":48,"healthyVolunteers":49,"sex":17,"minAge":18,"maxAge":4,"enrollmentInfo":50,"targetDuration":4,"studyType":52,"phases":4,"briefSummary":53,"conditions":54,"keywords":56,"overallStatus":30,"whyStopped":4,"lastUpdateSubmitDate":61,"lastUpdatePostDateStruct":62,"startDateStruct":64,"completionDateStruct":66,"leadSponsor":68,"locationsCount":42},"100308137","cuhk-stroke-biobank-100308137","NCT03291392","CUHK Stroke Biobank","Inclusion Criteria:\n\n1.

The complex pathology of atherosclerosis could lead to recurrent stroke, including shear stress on the endothelium, disturbance of the flow, occlusion at the origin of the perforating artery, and other complications (plaque inflammation, plaque hemorrhage, plaque rupture) that could lead to stroke and recurrent stroke. Therefore, The exact determination of the etiology of stroke due to atherosclerosis is the most critical factor for treatment and prognostic. On the other hand, HR-MRI could be a useful imaging modality to evaluate the characteristics of plaque in stroke patients due to atherosclerosis stenosis, which will help us find out the etiology of stroke. Previous studies have demonstrated its prognosis value in predicting recurrent stroke in the same vascular territory. The investigators hypothesize that with an appropriate evaluation, HR-MRI could help to predict recurrent stroke in the same vascular territory in patients with high-risk plaque characteristics on HR-MRI. These findings could contribute to individual treatment according to etiology.\n\nThe investigators intend to conduct a study to determine the correlation between plaque characteristics and recurrent stroke in the same vascular territory in ischemic stroke patients due to middle cerebral artery stenosis.",[28,29],"2024-05-04",{"date":85,"type":34},"2024-05-08",{"date":87,"type":34},"2024-04-01",{"date":89,"type":22},"2026-06",{"name":91,"class":41},"University Medical Center Ho Chi Minh City (UMC)"]
