What is Coronary Artery Disease?

heart
Coronary Artery Disease (CAD) happens when the arteries that supply blood to the heart muscle become hardened and narrowed. This is due to the buildup of cholesterol and plaque on the inner walls of the arteries. As the buildup grows, less blood can flow through the arteries. As a result, the heart muscle can't get the blood or oxygen it needs.

People with CAD will often experience chest pains (aka angina) or even a heart attack. Over time, CAD can also weaken the heart muscle and contribute to heart failure and arrhythmias.

According to the National Institutes of Health, coronary artery disease is the most common type of heart disease. It is also the leading cause of death in the United States in both men and women.


What doctor should you see for coronary artery disease?
