Coronary artery disease (CAD)
What is it?
CAD occurs when the blood vessels – the coronary arteries – that bring oxygen and nutrients to the heart muscle become narrowed and/or blocked by fatty deposits called plaques.
This narrowing or blockage can cause the heart to not receive enough oxygen. Under these conditions, an injury to the heart muscle can occur. This is what is commonly known as a heart attack or myocardial infarction.
