What is Angina? – Symptoms of Angina


Angina is a symptom of Coronary Artery Disease (CAD), the most common type of heart disease.

Angina happens when the plaque builds up in the coronary arteries.

This build up of plaque is called atherosclerosis. As the plaque builds up, the coronary arteries become narrower and stiff. Blood flow to the heart is then reduced.

This decreases the oxygen supply to the heart muscle.
