Angina is defined as episodes of severe chest pain due to inadequate blood flow to the myocardium.

• A. Myocardial infarction
• B. Endocarditis
• C. Angina
• D. Coronary artery disease

Answer: (C)

Angina is chest pain that comes from reduced blood flow to the heart muscle, meaning the heart isn’t getting enough oxygen during times of increased demand. The statement describes this exact scenario, so it identifies the symptom as angina. A heart attack, or myocardial infarction, is when ischemia is severe and prolonged enough to cause heart muscle tissue to die. Endocarditis is an infection of the heart’s inner lining or valves. Coronary artery disease is the underlying process—narrowing of the coronary arteries due to atherosclerosis—that can lead to angina or a heart attack, but it is not the chest-pain definition itself.
