The goal of this clinical trial is to test the safety and effectiveness of antiplatelet therapy in acute ischemic stroke (AIS) patients with thrombocytopenia. Participants will be prescribed antiplatelet agents and followed up for 3 months.

Antiplatelet therapy is widely used in non-cardiogenic AIS patients for secondary prevention. However, it may also increase the risk of bleeding complications, especially in patients with thrombocytopenia. The goal of this clinical trial is to test the safety and effectiveness of antiplatelet therapy in acute ischemic stroke (AIS) patients with thrombocytopenia. Participants will be prescribed antiplatelet agents and followed up for 3 months.

Inclusion Criteria:

• Age > 18 years old
• Acute ischemic stroke or transient ischemic attack with onset < 7 days
• The last blood routine test before enrollment indicates platelet count < 100 x 10^9 and > 30 x 10^9

Exclusion Criteria:

• Chronic renal dysfunction (GFR < 30ml/min) or severe hepatic injury
• Indications for anticoagulation therapy, e.g. atrial fibrillation
• Myocardial infarction within 6 months before enrollment or received percutaneous coronary intervention in the past
• Have or plan to receive CEA or CAS in the following 3 months
• Life expectancy less than 1 year
• Plan to receive invasive surgery in the following 3 months and have high risk of uncontrollable bleeding
• Pregnant or lactating women
• Individuals identified by researchers as unsuitable for participation in the study due to other reasons.
