What is the cause of angina?

Angina happens when the heart muscle doesn’t get enough oxygen because the coronary arteries are narrowed or blocked, reducing blood flow to the heart. This mismatch between oxygen supply and demand, especially during activity or stress, causes chest pain or discomfort that often improves with rest or nitroglycerin. The other options describe different conditions—infection of heart valves (not angina), blockage of a leg vein (deep vein thrombosis), or inflammation of the lungs (pneumonia)—and do not explain the heart-related chest pain pattern of angina.
