What is a common treatment for stable angina?

Nitroglycerin is commonly used as a treatment for stable angina because it functions as a vasodilator, relaxing the smooth muscles in the blood vessels. This leads to an increase in blood flow to the heart muscle, which alleviates the chest pain associated with angina. By reducing myocardial oxygen demand and improving oxygen supply, nitroglycerin effectively helps to manage the symptoms of stable angina during episodes of exertion or stress.

Stable angina typically occurs in response to physical activity, stress, or other triggers, and nitroglycerin is often administered sublingually (under the tongue) for rapid relief. Its quick onset of action makes it an ideal choice to address acute attacks of angina. It's also important to note that while other medications such as aspirin or beta-blockers like metoprolol may play roles in the overall management of coronary artery disease and to prevent heart attacks, nitroglycerin specifically targets the acute symptom relief associated with stable angina episodes.
