A healthy person has open and smooth arteries that allow blood to flow to all areas of the body especially the heart. Heart disease is when one or more of these arteries are damaged or blocked. This causes a decrease in blood flowing to the heart.
Blockages in your arteries are often made of fatty deposits called plaque. These blocked arteries can oftentimes be treated. If the blockage is severe, you may need coronary artery bypass surgery.
When the heart is not getting a good blood supply, you may feel symptoms such as chest pressure and/or shortness of breath. It is very important that you report your symptoms to your doctor right away or call 911.
