What is the difference between congestive heart failure and coronary artery disease or do you have both?

Different problems. Coronary artery disease is a narrowing of the small blood vessels that supply blood and oxygen to the heart. (http://1.Usa. Gov/lrisvf) congestive heart failure is a condition in which the heart can no longer pump enough blood to the rest of the body. (http://1.Usa. Gov/lrirha).
