Uncontrolled hypertension is defined by the American Heart Association (AHA) as blood pressure greater than 140/90 mm Hg (millimeters of mercury).
High blood pressure, or hypertension, is a blood pressure reading of 140/90 or higher. Years of high blood pressure can damage artery walls, causing them to become stiff and narrow. This includes the arteries carrying blood to the heart.As a result, your heart cannot get the blood it needs to work well.This can cause a heart attack. A blood pressure reading of 120/80 to 139/89 is considered prehypertension. This means that you don't have high blood pressure now but are likely to develop it in the future.s a result, your heart cannot get the blood it needs to work well. This can cause a heart attack.
