This damage can lead to atherosclerosis, or hardening of the arteries. This means that plaque, made of fats and other substances, builds up in the coronary arteries.

    If your heart disease gets worse, your arteries will narrow, and less blood will flow to your heart. You may start to have angina symptoms, such as chest pain or discomfort when you exercise or feel stressed. This is called stable angina.
