Which factor commonly precipitates angina symptoms?

• A. Eating
• B. Exertion
• C. Sleeping
• D. Emotional stress

Answer: (B)

Angina arises when the heart muscle doesn’t get enough oxygen to meet its increased needs. During exertion, heart rate, contractility, and blood pressure rise, boosting oxygen demand. If the coronary arteries are narrowed from atherosclerosis, they can’t increase blood flow enough, leading to myocardial ischemia and chest pain. That’s why exertion is the most common trigger for angina in stable disease. Eating, sleeping, or emotional stress can also provoke symptoms, but they’re less consistent triggers than physical activity.
