Which of the following is a common subjective symptom of angina pectoris?

Sub-sternal pain or pressure is a hallmark subjective symptom of angina pectoris. This pain is typically described as a feeling of heaviness, tightness, or pressure in the chest and may also radiate to the shoulders, neck, arms, or back. Angina occurs when the heart muscle does not receive enough oxygen-rich blood, often due to coronary artery disease. This pain is transient and usually occurs during physical exertion or stress, alleviating with rest or nitroglycerin.

In contrast, other symptoms such as abdominal pain, sore throat, or coughing are generally not associated with angina. Abdominal pain can be indicative of gastrointestinal issues rather than cardiac conditions. A sore throat typically signals an upper respiratory or infectious condition, and coughing might be related to a respiratory problem rather than a cardiac one. Understanding these distinctions is crucial for recognizing and responding to angina pectoris effectively.
