Angina is best described as chest pain caused by exercise intolerance. Which option matches this characterization?

• A. Sharp Tearing Chest Pain Radiating To The Back
• B. Chest Pain Caused By Exercise Intolerance
• C. Chest Pain That Worsens With Rest And Improves With Nitroglycerin
• D. Pain Unrelated To Exertion

Answer: (B)

Angina is chest pain caused by transient myocardial ischemia that is triggered by increased oxygen demand, usually with activity. The best match is the option that describes chest pain caused by exercise intolerance because exertion raises the heart’s workload and can outstrip blood supply, producing the typical, pressure-like pain that is relieved by rest or nitroglycerin. This pattern fits stable angina, where symptoms are reproducible with activity and improve with rest or vasodilators. The other descriptions point to different problems: sharp tearing chest pain radiating to the back suggests aortic dissection; chest pain that worsens with rest and improves with nitroglycerin contradicts the exertion-linked nature of angina; and pain unrelated to exertion is not angina.
