In the United States, the most common type of heart disease is coronary artery disease (CAD), which can lead to heart attack. You can greatly reduce your risk for CAD through lifestyle changes and, in some cases, medication.

Coronary artery disease can cause a heart attack. If you have a heart attack, you are more likely to survive if you know the signs and symptoms, call 9-1-1 right away, and get to a hospital quickly. People who have had a heart attack can also reduce the risk of future heart attacks or strokes by making lifestyle changes and taking medication.
