Intracranial ArteriosclerosisStenosis Artery2 moreThe primary objective of this trial is to evaluate the long-term safety and efficacy of the NOVA intracranial drug-eluting stent system in "real world" patients with intracranial atherosclerotic stenosis.
Feedback Loop Between Intracranial Atherosclerosis and Cerebral Small Vessel Disease
ICAS - Intracranial AtherosclerosisCerebral Small Vessel DiseasesThe present study aims at verifying the mutual effects between intracranial large artery atherosclerosis and cerebral small vessel disease on disease progression and prognosis by magnetic resonance imaging, and providing biomarkers for the early prevention and treatment of cerebrovascular disease.
High-resolution Magnetic Resonance Imaging of Intracranial Atherosclerotic Plaques in Ischemic Stroke...
StrokeIntracranial Atherosclerosis1 moreIntracranial atherosclerotic disease is the most common cause of ischemic stroke in Asia, also in China. Currently, despite vascular recanalization therapy, statins are one of the main drug choices for treating atherosclerotic plaque. High resolution magnetic resonance imaging (HRMRI) can accurately assess the status of intracranial and extracranial arterial plaque, and has high consistency with histopathology. Thus, HRMRI technology has been widely used to monitor the efficacy of drug treatment for atherosclerotic plaque in clinical trials or practice. As a non-invasive technique, HRMRI make it possible to assess the morphologic characteristics of vascular wall and plaque composition of intracranial artery in vivo. It can quantitative analysis including components such as lipid-rich necrotic core, fiber cap thickness, intra-plaque hemorrhage, calcification, etc. Therefore, it is crucial for evaluating the etiology of ischemic stroke and developing secondary prevention strategies. At present, there is a lack of large-scale and prospective study to evaluate the etiology of ischemic stroke including cryptogenic stroke based on HRMRI. In this context, this study aims to establish a multi center HRMRI database of intracranial arteries among Chinese patients with ischemic stroke.

Anticoagulation Using Rivaroxaban on Top of Aspirin in Intracranial Atherostenosis Stenosis
Ischemic StrokeIntracranial Atherosclerosis1 moreThe primary goal of the clinical trial is to test the effect of oral rivaroxaban plus aspirin in patients with recent stroke/ transient ischemic attack (TIA) caused by intracranial artery stenosis. Participants will be divided into 2 groups to receive either oral rivaroxaban plus aspirin or oral clopidogrel plus aspirin. The main question it aims to answer is whether the experimental group (oral rivaroxaban plus aspirin) is superior to the control group ( oral clopidogrel plus aspirin) to lower recurrent stroke/TIA or death in these patients during 1 year of follow-up.

Intracranial StenosisLarge Vessel Occlusion1 moreThe aim of this study is to develop an international multicenter registry of patient data and outcomes for patients undergoing mechanical thrombectomy for emergent large vessel occlusion with residual underlying stenosis following successful revascularization.
Reducing Intracranial atheroSclErosis With Repatha
Ischemic StrokeThe purpose of this study will be to understand the underlying mechanism by which PCSK9 inhibition reduces the rate of ischemic stroke seen in the pivotal studies that led to its FDA approval for ASCVD such as ischemic stroke. Those trials (FOURIER and ODYSSEY) enrolled almost 50,000 patients and showed that PCSK9 inhibition therapy is safe and effective. The investigators hypothesize that PCSK9 inhibition lowers the rate of stroke by reducing atherosclerotic plaque, which would be particularly beneficial for patients with intracranial atherosclerosis, who have the highest rate of recurrent stroke of any stroke mechanism.
