WHAT THE CHANGES MEAN
The guidelines set new categories and get rid of “prehypertension”:
—Normal: Under 120 over 80
—Elevated: Top number 120-129 and bottom less than 80
—Stage 1: Top of 130-139 or bottom of 80-89
—Stage 2: Top at least 140 or bottom at least 90
That means 46 percent of U.S. adults have high pressure (stages 1 or 2) versus 32 percent under the old levels.
