CAD stands for which condition?

• A. Cardiac Arrest Disorder
• B. Coronary Artery Disease
• C. Circulatory Anomaly Disorder
• D. Chronic Angina Disease

Answer: (B)

Coronary artery disease is the condition abbreviated as CAD. It describes narrowing or blockage of the arteries that supply blood to the heart muscle, usually from atherosclerosis. This reduced blood flow can lead to chest pain (angina), and more serious events like a heart attack if a rich blood supply is severely cut off. Understanding this helps distinguish CAD from terms that aren’t standard diagnoses: cardiac arrest disorder isn’t a recognized disease name, circulatory anomaly disorder isn’t a common cardiology label, and chronic angina disease isn’t a separate, widely used diagnosis—angina is typically a symptom or manifestation within coronary artery disease rather than a standalone disease name.
