Which treatment is commonly used for chronic stable angina?

The treatment commonly used for chronic stable angina is beta blockers. These medications work by reducing the heart's workload and lowering oxygen demand, which helps to relieve the symptoms of angina. By blocking the effects of adrenaline on the heart, beta blockers slow down heart rate and reduce contractility, which can effectively control episodes of angina in patients with known coronary artery disease.

Beta blockers not only help alleviate chest pain associated with angina but also provide further cardiovascular benefits such as improving survival rates post-myocardial infarction and helping to manage hypertension. Their ability to improve exercise tolerance is also particularly beneficial for patients experiencing stable angina during physical activity.

While the other options may have their uses in various cardiovascular conditions, they do not specifically target the management of chronic stable angina as effectively as beta blockers do. Antidepressants primarily address mood disorders, diuretics are typically used for fluid overload conditions like heart failure, and ACE inhibitors are more inclined toward improving outcomes in heart failure and reducing cardiovascular risk rather than directly addressing the acute symptoms of angina.
