Antiplatelet aggregation refers to preventing platelets from aggregating and adhering together to produce blood clots, thus preventing thromboembolic diseases. Platelets have the function of mutual adhesion. In normal blood circulation, platelets are scattered and distributed, when platelets in blood vessels are stimulated, they will aggregate and stick together with each other, forming platelet aggregation and red thrombus. When the blood vessel rupture bleeding platelet aggregation can block the local damaged blood vessel wall, play the role of hemostasis. However, excessive platelet aggregation may lead to thromboembolic disease. Antiplatelet aggregation is to prevent platelets from aggregating and adhering to form red blood clots, preventing the formation of thromboembolic disease. Antiplatelet aggregation is usually done through medications such as aspirin, dipyridamole, and ticlopidine. All of these medications need to be used under a doctor’s supervision to avoid self-medication.
