What is Heart Disease?
When people talk about heart disease, they are usually talking about coronary artery disease (CAD). This is the most common type of heart disease.

CAD is when the arteries that bring blood to the heart muscle become narrow or blocked. This happens when plaque (plak) builds up on the inner wall of the artery. The more plaque there is, the less blood can flow through to the heart.

If the artery is blocked, the heart cannot get the blood and oxygen it needs. This can cause chest pain or a heart attack. Over time, heart disease can weaken the heart muscle and cause heart failure.

What is a Heart Attack?
A heart attack happens when blood flow to the heart is blocked. The heart cannot get any oxygen, and parts of the heart muscle may die.

Know the signs of a heart attack. The signs of a heart attack may be different for men and women.

What is Heart Failure?
Heart failure does not mean that the heart has stopped. It means that the heart cannot pump blood the way it should to the rest of the body.

What causes plaque in the arteries?

  • Smoking
  • High amounts of fat and cholesterol in the blood
  • High blood pressure
  • High levels of sugar in the blood (usually because of diabetes)

All of these factors can cause plaque to build up in the arteries. Over time, the plaque can narrow or completey block the arteries.

Heart disease is the leading cause of death for both men and women in the United States. To learn more about managing heart disease, visit these Web sites:
