What is the most common symptom of coronary heart disease (CAD)?

Angina is recognized as the most common symptom of coronary heart disease (CAD). It is characterized by chest pain or discomfort that occurs when the heart muscle does not receive enough blood and oxygen, often felt during physical activity or emotional stress. The pain can radiate to the arms, neck, jaw, or back. Angina is a key indicator of underlying heart issues and may signal impending heart problems, making it an essential symptom to recognize.

While shortness of breath, high blood pressure, and fatigue can be associated with coronary heart disease, they are not as definitive or common as angina when it comes to identifying this specific condition. Shortness of breath can occur due to various conditions, and high blood pressure is often a contributing factor rather than a direct symptom. Fatigue may occur in many situations and can result from numerous reasons, making angina the more specific and significant indicator of CAD.
