|Coronary heart disease||
Coronary heart disease (CHD) is a narrowing of the small blood vessels that supply blood and oxygen to the heart, usually resulting from the build-up of fatty material and plaque (atherosclerosis).
As the coronary arteries narrow, the flow of blood to the heart can slow or stop, causing chest pain, shortness of breath, heart attack, or other symptoms. There are many factors that increase your risk for CHD. Some risks are based on family history.
