Which term most closely matches chest pain caused by inadequate oxygen to the heart?

• A. Angina
• B. Asthma
• C. Anaphylaxis
• D. Allergy

Answer: (A)

Chest pain caused by the heart not getting enough oxygen is angina. It happens when the coronary arteries can’t supply enough blood to meet the heart’s needs, often because of narrow or blocked arteries. The resulting chest pressure or squeezing may also spread to the arms, neck, jaw, or back. This is different from asthma, which involves the airways, and from anaphylaxis or a general allergy, which are immune reactions that can affect breathing and circulation but aren’t specifically about the heart’s oxygen supply. Angina reflects a mismatch between oxygen supply and demand in heart muscle, usually brought on by activity or stress and often relieved by rest or prescribed medication.
