Stable angina is typically triggered by which of the following?

• A. Rest
• B. Physical exertion
• C. Stressful emotional situations
• D. Severe weather changes

Answer: (B)

Stable angina is primarily characterized by predictable episodes of chest pain that typically occur during situations that increase the workload of the heart. Physical exertion is a classic trigger for stable angina because physical activity increases oxygen demand in the heart muscle. During exercise, the heart pumps more blood to supply oxygen to the muscles, which can lead to ischemia if there is an underlying coronary artery disease that restricts blood flow. This results in the symptoms associated with angina. Other factors, such as emotional stress and extreme weather changes, can also contribute to angina, but they are less commonly regarded as primary triggers compared to physical exertion. In the case of stable angina, the pain usually resolves with rest or the administration of nitroglycerin, which further solidifies the relationship between increased physical activity and angina episodes.
