How long does angina pectoris typically last?

• A. Less than 3 minutes
• B. About 3 to 8 minutes
• C. Approximately 15 to 20 minutes
• D. Over 30 minutes

Answer: (B)

Angina pectoris is characterized by chest pain or discomfort due to inadequate blood supply to the heart, usually during exertion or stress. The typical duration of an angina episode is generally about 3 to 8 minutes. This is because the pain occurs as a result of temporary ischemia—meaning there is a transient reduction in blood flow to the heart muscle—commonly associated with physical activity or stress. The discomfort typically resolves with rest, supplemental oxygen, or the use of nitroglycerin, which helps alleviate the symptoms by increasing blood flow. If angina lasts longer than 15 to 20 minutes or occurs at rest, it can indicate a more serious condition, such as a heart attack, and should be treated as a medical emergency. Thus, the range of 3 to 8 minutes appropriately reflects the usual duration of stable angina episodes.
