Angina is chest pain caused by reduced blood flow to the heart muscles. It's not usually life threatening, but it's a warning sign that you could be at risk of a heart attack or stroke.

With treatment and healthy lifestyle changes, it's possible to control angina and reduce the risk of these more serious problems.

Angina is usually caused by the arteries supplying blood to the heart muscles becoming narrowed by a build-up of fatty substances.

This is called atherosclerosis.

Things that can increase your risk of atherosclerosis include:

- an unhealthy diet

- a lack of exercise

- smoking

- increasing age

- a family history of atherosclerosis or heart problems
