What symptom is commonly associated with Coronary Artery Disease (CAD)?

Chest pain, often referred to as angina, is a hallmark symptom associated with Coronary Artery Disease (CAD). This condition involves the narrowing or blockage of the coronary arteries due to atherosclerosis, which can lead to insufficient blood flow to the heart muscle. When the heart doesn't receive enough oxygen-rich blood, it responds with discomfort or pain, which is typically felt in the chest but may also radiate to the arms, back, neck, or jaw.

Angina can manifest in various forms, including stable angina, which occurs predictably with exertion, and unstable angina, which can occur unexpectedly and may indicate a more severe condition. Recognizing angina as a primary symptom of CAD is crucial for diagnosis and management, as it often serves as a warning sign for potential heart attacks or more serious cardiovascular events.

In contrast, while dizziness, shortness of breath, and fatigue can occur in patients with CAD, they are not as specifically indicative of the disease as chest pain. These symptoms can result from a variety of other conditions, making chest pain the most definitive and commonly recognized symptom of coronary artery disease.
