Prehypertension is a relatively new classification for people with a blood pressure level that is not healthy, but not yet in the hypertension range. Here are six things to know about the condition. According to the American Heart Association, a healthy blood pressure reading is 120/80 or less. The top number is the systolic pressure, which measures the pressure in the arteries when the heart beats.

Prehypertension is classified by a systolic pressure between 120 and 139, or a diastolic pressure between 80 and 89.
