If your heart failure is caused by coronary heart disease, one or more of your coronary arteries (arteries that supply blood to your heart muscle) has become narrow due to the build up of a cholesterol containing mass (plaque) inside the artery wall.
This narrowing of your artery reduces the amount of oxygen and nourishment that are able to reach your heart muscle, causing angina (chest pain) oftern during exercise. This lack of oxygen and nutrients makes the muscle work harder in order to pump blood around your body.
Coronary artery disease can be delayed or even prevented by lifestyle and medical approaches. If you have this condition you should discuss with your doctor any changes you could make to your lifestyle and how your doctor can help you to prevent any further damage, slow the build up of plaque in the arteries, and prevent progression of your heart failure.
