Ischemic Stroke Clinical Trial
Official title:
Low-dose Aspirin Therapy in Patients With Non-Cardioembolic Ischemic Stroke and Microbleeds
The purpose of this study is to investigate the safety and efficacy of low-dose (50mg) aspirin as a secondary prevention drug in patients with Non-Cardioembolic Ischemic Stroke accompanied by cerebral microbleeds.
Cerebral microbleeds are caused by microvascular lesions in the brain, which is a subclinical deposition of hemosiderin after the damage of microvascular. Aspirin is the most widely used anti-thrombotic drug in the secondary prevention of patients with non-cardioembolic ischemic stroke. Studies have shown that conventional doses of aspirin can increase the incidence of intracranial hemorrhage in ischemic stroke patients with cerebral microbleeds. For such patients, how to carry out effective and safe anti-thrombotic therapy is still unclear. The AIM study aims to provide reliable data on the effects of low-dose Aspirin (50mg target recruitment 200) in patients with non-cardioembolic ischemic stroke and cerebral microbleeds compared to conventional dose (100mg target recruitment 200). Patients presenting with acute (<3 weeks) non-cardioembolic ischemic stroke and microbleeds (≧1 microbleeds in SWI scans) will be randomly assigned to the secondary stroke prevention therapy of low-dose or conventional dose aspirin for 6 months. ;
