What is heart failure

Heart failure is a common but serious and possibly progressive condition that frequently has no cure.

Heart failure is a serious medical condition where the heart does not pump blood around the body as well as it should.
This means that your blood can't deliver enough oxygen and nourishment to your body to allow it to work normally.

This, for example, may cause fatigue in your muscles. It also means that you can't eliminate waste products properly - leading to a build up of fluid in your lungs and other parts of your body, such as your legs and abdomen.

Heart failure often develops because you have (or had) a medical condition, such as
coronary artery disease ( coronary artery disease happens when the arteries narrow or close preventing blood flow), or a heart attack (aka heart failure) damage that happens to the heart muscle when the coronary artery becomes so narrow that blood can't pass through.
