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) have narrowed 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 is able to reach your heart muscle, causing angina (chest pain) often during exercise. This lack of oxygen and nutrients makes the muscle work harder in order to pump blood around your body. Coronary artery disease
Occurs when the coronary arteries become narrowed or completely blocked. This causes blood flow to be reduced and can lead to angina, heart attack and heart failure.
