American Heart Association/the American College of Cardiology and nine other professional organizations have issued a new hypertension clinical practice guideline (CPG) on November 2017, which has lowered the hypertension threshold to 130/80 mmHg. American Academy of Family Medicine has decided to not endorse this new CPG for various reasons including flaws in CPG development process and a limited additional benefit for lower treatment targets. The major concern was intellectual conflict of interest (COI). Substantial weight was given to SPRINT trial, which provided the basis for the recommended change in blood pressure targets. It is a serious intellectual COI that the Chair of the SPRINT trial steering committee was commissioned as chair of the guideline panel. The new threshold would lead to 46 percent of the U.S. adult population being categorized as having hypertension, while using the previous threshold that figure would be 32 percent. Should we call this change as overdiagnosis?
