Hypertension redefined 130 systolic or above

New guidelines from the American College of Cardiology and American Heart Association (AHA), among others, define substantially more U.S. adults as having hypertension than the 2003 Joint National Committee (JNC 7) report's definition. The new ACC/AHA guidelines — unveiled recently at the AHA's annual meeting — define systolic blood pressure at or above 130 mm Hg as constituting hypertension, while the older definition set the threshold at 140 or above.
