Study summary

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.

Read the detailed description

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.
