What is the primary purpose of aspirin in the treatment of angina pectoris?

The primary purpose of aspirin in the treatment of angina pectoris is to prevent blood from clotting as quickly. Aspirin is an antiplatelet medication that works by inhibiting the aggregation of platelets, which can play a significant role in the formation of blood clots. During angina pectoris, the heart muscle doesn’t receive enough blood and oxygen, often due to narrowed coronary arteries. If clots form, they can further block these already compromised vessels, exacerbating the situation. By reducing the likelihood of clot formation, aspirin helps to maintain blood flow and can alleviate or prevent symptoms associated with angina, thus playing a critical role in managing the condition and reducing the risk of more serious cardiovascular events.
