What term is used when a person's coronary arteries are not able to supply enough blood and oxygen to the heart muscle and pain occurs as a result?

• A. Heart attack
• B. Angina
• C. Arrhythmia
• D. Aneurysm

Answer: (B)

Chest pain that happens when the coronary arteries can’t supply enough blood and oxygen to the heart muscle is called angina. This occurs when the heart’s oxygen demand is not matched by supply, usually due to narrowed arteries, causing transient ischemia that feels like pressure, squeezing, or tightness. Angina is often triggered by exertion or stress and tends to improve with rest or nitroglycerin. The other terms describe different problems: a heart attack is a complete blockage causing heart tissue damage (myocardial infarction), an arrhythmia is an abnormal heart rhythm, and an aneurysm is a bulging, weakened area in a vessel wall. Therefore, the term that fits the described situation is angina.
