Overview

In 2004, the Seventh Report of the Joint National Committee (JNC 7) classified blood pressure values into 4 categories: normal, prehypertension, stage I hypertension, and stage II hypertension. In 2007, the Task Force for the Management of Arterial Hypertension of the European Society of Hypertension (ESH) and the European Society of Cardiology (ESC) classified blood pressure into 7 categories. This classification remained unchanged in the 2013 ESH/ESC classification. The ESH/ESC classification excludes JNC 7’s pre-hypertension category, but includes 3 different grades of hypertension in contrast to JNC 7’s two-stage classification of hypertension.

JNC 7 Classification of Blood Pressure

According to the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure blood pressure values were classified as follows:

Blood Pressure Classification	Systolic (mm Hg)		Diastolic (mm Hg)
Normal	< 120	and	< 80
Pre-Hypertension	120-139	or	80-89
Stage 1 Hypertension	140-159	or	90-99
Stage 2 Hypertension	>160	or	>100

ESH/ESC Classification of Blood Pressure

In Europe, a different classification of blood pressure was introduced in 2007 by The Task Force for the Management of Arterial Hypertension of the European Society of Hypertension (ESH) and of the European Society of Cardiology (ESC). According to the 2013 Guidelines for the Management of Arterial Hypertension, blood pressure values were classified as follows:

Blood Pressure Classification	Systolic (mm Hg)		Diastolic (mm Hg)
Optimal	< 120	and	< 80
Normal	120-129	and/or	80-84
High Normal	130-139	and/or	85-89
Grade 1 Hypertension	140-159	and/or	90-99
Grade 2 Hypertension	160-179	and/or	100-109
Grade 3 Hypertension	≥ 180	and/or	≥110
Isolated Systolic Hypertension	≥140	and	<90
