What is Heart Disease?


Updated November 13, 2011

The heart is the organ that pumps blood, with its life-giving oxygen and nutrients, to all tissues of the body. If the pumping action of the heart becomes inefficient, vital organs like the brain and kidneys suffer. And if the heart stops working altogether, death occurs within minutes. Life itself is completely dependent on the efficient operation of the heart.

There are many kinds of heart disease, and they can affect the heart in several ways. But the ultimate problem with all varieties of heart disease is that, in one way or another, they can disrupt the vital pumping action of the heart.
