Prehypertension: an opportunity for a new public health paradigm.

From 2005 to 2006, approximately 3 of 8 adults in the United States had blood pressure (BP) in the prehypertensive range of 120 to 139/80 to 89 mm Hg and roughly 1 in 8 adults had BP in the range of 130 to 139/85 to 89 mm Hg, which is referred to as high normal BP or stage 2 prehypertension. Adults with stage 2 prehypertension are also roughly twice as likely as adults with normotension to suffer cardiovascular disease. The Seventh Report of the Joint National Committee on Hypertension recommended only lifestyle changes for most prehypertensive patients. BP in the range of 120 to 129/80 to 84 mm Hg is also associated with increased risk but roughly half of that of stage 2 prehypertension.
