prehypertensionA borderline health state of increased blood pressure (BP) that falls short of the measurable parameters at which surveillance and/or therapy would be required based on evidence-based guidelines, defined by the Joint National Committee report as a systolic BP between 120 and 139 mm Hg, and/or a diastolic BP between 80 and 89 mm Hg. BP greater than the above values is considered hypertension.
