What is heart disease?

Heart disease begins when cholesterol, fatty material, and calcium build up in the arteries. When this occurs in the arteries that supply the heart, this buildup, or plaque, causes the arteries to narrow, so that oxygen delivery to the heart is reduced. The reduction in oxygen delivery to the heart can create chest pain, also called angina.
