In the management of ACS, what is the primary reason for using aspirin?

The primary reason for using aspirin in the management of Acute Coronary Syndrome (ACS) is to inhibit platelet aggregation and decrease clot formation. Aspirin works as an antiplatelet agent, which means it prevents platelets in the blood from clumping together. This is crucial in ACS, as the development of clots can lead to blockages in coronary arteries, exacerbating ischemia and potentially leading to a myocardial infarction (heart attack).

By reducing the ability of platelets to form clots, aspirin helps maintain blood flow to the heart muscle, thereby mitigating damage and improving patient outcomes. This antiplatelet effect is a key component of acute management protocols for patients presenting with chest pain or other symptoms indicative of ACS.
