In November 2017, the American Heart Association (AHA) and American College of Cardiology (ACC) released a new clinical practice guideline on hypertension. In December 2017, following the news, the American Dental Association (ADA) News reported the updates.
The guidelines, in a nutshell, state that normal blood pressure is under 120/80 mm Hg, whereas previously, normal was under 140/90 mm Hg. The categories of prehypertension, hypertension stage 1, and hypertension stage 2 have also changed.
We have these updates in our NBDHE review packages.
