Prehypertension, also known as high normal blood pressure and borderline hypertensive (BH),[1] is a medical classification for cases where a person's blood pressure is elevated above optimal or normal, but not to the level considered hypertension (high blood pressure). Prehypertension is now referred to as "elevated blood pressure" by the American College of Cardiology (ACC) and the American Heart Association (AHA).[2] The ACC/AHA define elevated blood pressure as readings with a systolic pressure from 120 to 129 mm Hg and a diastolic pressure under 80 mm Hg,[3] Readings greater than or equal to 130/80 mm Hg are considered hypertension by ACC/AHA and if greater than or equal to 140/90 mm Hg by ESC/ESH.[4] and the European Society of Hypertension defines "high normal blood pressure" as readings with a systolic pressure from 130 to 139 mm Hg and a diastolic pressure 85-89 mm Hg.[5]
