What does aspirin do to prevent cerebral infarction?

Aspirin is mainly used to prevent cerebral infarction by anti-platelet aggregation and preventing thrombosis. For cerebral infarction, it is mainly caused by atherosclerosis. When blood components flow through, it can form a thrombus attached to the wall. Aspirin can prevent platelet aggregation and prevent thrombosis. Therefore, it has certain clinical effects on preventing cerebral infarction. At the same time, patients with cerebral infarction, if caused by immune diseases, such as arteritis, etc., are advised to take aspirin for anti-platelet aggregation and certain anti-immune inflammatory reactions. Therefore, aspirin is widely used in clinical practice to prevent cerebral infarction. However, some patients will show gastrointestinal reactions after taking aspirin. For this situation, patients can be advised to take clopidogrel hydrogen sulfate for anti-platelet aggregation therapy if necessary.
