Which term is most closely associated with chest pain caused by insufficient blood flow to the heart?

• A. Angina
• B. Pulse Oximetry
• C. Atrophy
• D. Bronchitis

Answer: (A)

Chest pain caused by not enough blood reaching the heart is called angina. This happens when the heart muscle doesn’t get enough oxygen because the coronary arteries are narrowed, often from atherosclerosis. The pain is typically described as pressure or squeezing in the chest and may occur with activity or stress, often easing with rest or nitroglycerin. The other terms don’t describe this condition: pulse oximetry is just a way to measure how much oxygen is in the blood, atrophy means wasting away of a tissue, and bronchitis is inflammation of the airways in the lungs. So the term that fits the symptom best is angina.
