What is the first-line medication for managing unstable angina?

The first-line medication for managing unstable angina is aspirin, which plays a crucial role in reducing the risk of cardiovascular events. Aspirin acts as an antiplatelet agent, inhibiting platelet aggregation and thereby decreasing the likelihood of thrombus formation in the coronary arteries. This is especially important in unstable angina, where acute plaque rupture can lead to increased clotting and myocardial ischemia.

By reducing platelet activation, aspirin helps stabilize the condition and prevent progression to myocardial infarction, making it essential in the acute management of unstable angina.

While other options have their place in the broader management of coronary artery disease and can help manage various symptoms and risk factors, they do not serve the same immediate purpose as aspirin during an episode of unstable angina. Statins are beneficial for long-term management in the prevention of cardiovascular diseases, anticoagulants are more suited for situations where blood clots need to be treated or prevented in patients with particular risk factors, and beta-blockers are often used for long-term control of angina symptoms and to manage heart rate but are not the primary treatment in the acute phase of unstable angina.
