Angina is best described as

• A. Dizziness due to dehydration.
• B. Chest pain caused by a muscle strain.
• C. Chest pain due to reduced blood flow to the heart.
• D. Shortness of breath due to lung disease.

Answer: (C)

Angina reflects chest discomfort caused by the heart not getting enough blood flow, usually from narrowed coronary arteries. This lack of adequate blood supply means the heart muscle isn’t receiving enough oxygen, especially during exertion or stress when it needs more oxygen. The pain is often described as pressure, squeezing, or heaviness in the chest and can spread to the arms, neck, jaw, or back. It’s typically relieved by rest or nitroglycerin, which helps dilate the arteries and improve blood flow. Understanding why this describes angina helps separate it from other causes of chest symptoms. Dizziness from dehydration isn’t chest pain and comes from reduced blood volume affecting overall circulation. Chest pain from a muscle strain is musculoskeletal and worsens with movement. Shortness of breath from lung disease involves the lungs or airways rather than the heart’s blood supply. Angina’s hallmark is chest pain tied to the heart’s blood flow, not a problem originating in muscles or lungs.
