Hypertension Categories

According to the U.S. national guidelines (JNC 7 Report), the following categories of hypertension have been defined:

Classification Systolic
(mmHg)
Diastolic
(mmHg)
Normal* <120 <80
Prehypertension 120-139 80-89
Stage 1 140-159 90-99
Stage 2 >160 >100

*Arterial pressures less than 90/60 mmHg are considered hypotension, and therefore not normal.

It is important to note that a hypertensive state may defined as an abnormal elevation of either systolic or diastolic pressure. In past years, the diastolic value was emphasized in determining whether or not a person was hypertensive.  However, elevations in systolic pressure ("systolic hypertension") are also associated with increased incidence of coronary and cerebrovascular disease (e.g., stroke). Therefore, we now recognize that both systolic and diastolic pressure values are important to note.
