The following definitions and staging system, which are based upon appropriately measured blood pressure, were suggested in 2017 by the American College of Cardiology/American Heart Association (ACC/AHA).
●Normal blood pressure
Systolic <120 mmHg and
Diastolic <80 mmHg
●Elevated blood pressure –
Systolic 120 to129 mmHg
Diastolic <80 mmHg
●Hypertension:
• Stage 1 –
Systolic 130 to 139 mmHg or
Diastolic 80 to 89 mmHg
• Stage 2 –
Systolic at least 140 mmHg or
Diastolic at least 90 mmHg
If there is a disparity in category between the systolic and diastolic pressures, the higher value determines the stage.
