Which term refers to chest pain due to insufficient blood flow to the heart?

• A. Laryngospasm
• B. Anemia
• C. Anoxia
• D. Angina

Answer: (D)

Chest pain caused by reduced blood flow to the heart is angina, also called angina pectoris. This happens when the coronary arteries don’t supply enough oxygen-rich blood to the heart muscle, often during exertion or stress when the heart needs more blood. The sensation is typically described as pressure, squeezing, or tightness in the chest and can radiate to the arm, neck, or jaw. It’s usually relieved by rest or nitroglycerin, which helps widen the vessels and improve blood flow. The other terms describe different issues: laryngospasm is a spasm of the vocal cords causing airway obstruction; anemia is a shortage of red blood cells or hemoglobin reducing the blood’s oxygen-carrying capacity; anoxia is a complete lack of oxygen to tissues. These don’t specifically define chest pain due to heart muscle ischemia, so angina is the precise term for this scenario.
