Hypertension, also known as high blood pressure, is a cardiac condition that can lead to many other problems, such as coronary artery disease, congestive heart failure, and many other health issues.

"Blood pressure" is the force of blood pushing against the walls of the arteries as the heart pumps out blood. If this pressure rises and stays high over time, it can damage the body in many ways.

About 1 in 3 adults in the United States has hypertension, though it usually has no symptoms. While it goes by unnoticed, it can damage the heart, blood vessels, kidneys, and other parts of your body. This is why knowing your blood pressure numbers is important, even when you're feeling fine. If your blood pressure is normal, you can work with your healthcare team to keep it that way. If your blood pressure is too high, you need treatment to prevent damage to your body's organs.
