What typically triggers angina pectoris?

• A. Increased physical activity
• B. Emotional stress or fear
• C. Consuming small meals
• D. Exposure to cold weather

Answer: (B)

Angina pectoris is typically triggered by factors that increase the demand for oxygen by the heart or decrease the supply of oxygen to the heart muscle. Emotional stress or fear is a significant trigger because these states can lead to heightened sympathetic nervous system activity, which increases heart rate and myocardial oxygen consumption. This elevated demand may surpass the heart's ability to supply adequate oxygen, especially in individuals with underlying coronary artery disease. In contrast, while increased physical activity is also a common trigger for angina, it is not the only factor at play. Consuming small meals generally does not significantly increase cardiac workload, and while some individuals may have angina symptoms triggered by changes in temperature, exposure to cold weather is not as universally recognized as a primary trigger compared to emotional stress. Therefore, emotional stress or fear stands out as a typical and well-documented trigger for angina pectoris.
