| You know how important your heart is, so it's no wonder people worry when they hear someone has heart problems.
Heart disease, also called cardiovascular (say: kar-dee-oh-vas-kyoo-lur) disease, mainly affects older people and means that there are problems with the heart and blood vessels.
You might know someone who has cardiovascular disease because 61 million Americans have some form of it. This disease includes a variety of problems, including high blood pressure, high blood cholesterol, hardening of the arteries, chest pain, heart attacks, and strokes.
