In November of last year, the American Heart Association (AHA), the American College of Cardiology and nine other groups recently redefined high blood pressure. The new parameters now reflect hypertension to be a reading of 130 over 80, down from 140 over 90. The change means that 46 percent of U.S. adults are now considered hypertensive – and the term “pre-hypertensive” is now a thing of the past.
