Blood supply to your heart


Coronary arteries supply your heart with blood

Coronary arteries supply blood to your heart

Your heart muscle has to work very hard to ensure that an adequate blood supply is pumped to your whole body. Because your heart is a muscle, it requires its own blood supply to provide it with the oxygen and nutrients it needs.

It gets this blood supply from the main coronary arteries, which lead straight off the main blood vessel (aorta) leaving your heart after picking up fresh oxygen.

What can go wrong with the blood supply?

If your coronary arteries are narrowed or blocked then the blood supply to your heart will be impaired. This is the most common form of heart disease, known as coronary heart disease (sometimes called coronary artery, or ischaemic heart, disease).
