Stable angina is most commonly provoked by which conditions?

Stable angina occurs when the heart’s oxygen demand rises but the coronary blood flow cannot increase enough because of fixed narrowing from atherosclerosis. Activities that boost heart rate, contractility, and blood pressure—like physical exertion or emotional stress—raise oxygen demand. Since the arteries can’t supply extra blood, the myocardium becomes ischemic and you feel chest discomfort. Rest or taking nitroglycerin lowers demand or improves supply, so the pain usually goes away quickly. Pain triggered by exertion or stress is the hallmark of stable angina, whereas nocturnal symptoms tend to point to vasospastic (variant) angina, and pain from heat isn’t a typical provoking factor.
