What is the primary use of Aspirin (ASA) in medical treatment?

The primary use of Aspirin (ASA) in medical treatment is for the secondary prevention of cardiovascular events. Aspirin functions as an antiplatelet medication, meaning it inhibits the aggregation of platelets in the blood, thereby reducing the risk of clot formation. This is crucial for individuals who have experienced a previous cardiovascular event, such as a heart attack or stroke, as it helps prevent future events by maintaining better blood flow and reducing the chance of reoccurrence.

While Aspirin does have other uses, such as providing pain relief, anti-inflammatory effects, and managing fever, these are not its primary indication in a clinical setting focused on cardiovascular health. The secondary prevention role is particularly important because it is a well-established practice in managing patients with a history of cardiovascular disease to improve their outcomes and reduce mortality.
