Angina pectoris is chest pain or discomfort that occurs when your heart muscle doesn't get as much oxygen-rich blood as it needs. This usually happens during physical activity or emotional stress, but can also occur at rest. Step 1: The most common cause of angina is coronary artery disease (CAD), where the arteries that supply blood to the heart muscle become narrowed or blocked, usually by plaque buildup (atherosclerosis). Step 2: When the heart muscle is starved of oxygen due to reduced blood flow, it signals pain. Step 3: Angina is a symptom of underlying heart disease, not a disease itself. It indicates that the heart is under strain. 1 more to go today. Send it over.
