What is the primary treatment for managing chronic stable angina?

The primary treatment for managing chronic stable angina is beta blockers. These medications are effective because they decrease myocardial oxygen demand by slowing the heart rate and reducing contractility, which is particularly beneficial during episodes of angina triggered by exertion or stress. Beta blockers also help alleviate symptoms by preventing the tachycardia that can occur during physical or emotional stress, thus improving exercise tolerance and enhancing overall quality of life for patients with stable angina.

While nitroglycerin plays an important role in the acute relief of anginal symptoms, it does not address the underlying long-term management of chronic stable angina. Calcium channel blockers can also be used for angina management, particularly in patients who may not tolerate beta blockers or in cases of vasospastic angina. ACE inhibitors have their own set of benefits, particularly in patients with hypertension or heart failure, but are not the primary choice for angina management specifically.
