What is Coronary Artery Disease? Dr. Christopher Nielsen: Coronary artery disease is one of the most common diseases in this country, and that's the most common condition that cardiologists see, and that is build up of plaque inside the arteries and blockages, and that begins early. It begins as we're teenagers, and as we start eating the wrong things, and the build up starts. It may not become a problem until we're later on in life in our 40s, 50s, 60s, 70s, when these blockages get more severe and start to cause angina, which is heart pain. That's usually when patients notice it and come in more urgently to see a cardiologist, and we have to do somethings. We would prefer to see patients much earlier before they even have any symptoms, so that we can start modifying their lifestyle using medications like Statins, or using diet therapy, and exercise therapy to try to prevent them from ever having problems in the future.
