Key result
American guidelines propose lower blood pressure cut-offs than European guidelines, creating a 10 mm Hg difference in office measurements and 5 mm Hg in ambulatory and home measurements.
Why the study?
Recent American and European guidelines disagree on hypertension cut-off values, and no study has compared them for agreement in detecting four hypertension phenotypes.
Cross-Sectional
Highlights the discrepancy between American and European guidelines in defining hypertension cut-offs, which can lead to different classifications of hypertension phenotypes in clinical practice.
May cause divergent hypertension classifications across borders; leaves open which thresholds best predict outcomes.
The American College of Cardiology and American Heart Association as well as the European Society of Hypertension and European Society of Cardiology have recently updated their recommendations for hypertension.1,2 American and European guidelines disagree for the cut-off values in the definition of hypertension for the first time. American guidelines proposed lower values for normal blood pressure (BP) creating a difference of 10 mm Hg in the office BP measurements (OBPMs), 5 mm Hg in 24-hour ambulatory BP measurements (ABPMs) and home BP measurements (HBPMs) from the European guidelines. As a result, a patient may be classified as hypertensive according to the American guidelines and normotensive according to European guidelines.1,2 To our knowledge, there is no study comparing the latest guidelines from Europe and America for their agreement in the detection of the four hypertension phenotypes, and especially white coat hypertension (WCHT) and masked hypertension...

Antza et al. (2020) conducted a cross-sectional in Hypertension. American vs European hypertension guidelines was evaluated on Agreement in the detection of hypertension phenotypes (white coat and masked hypertension). American guidelines propose lower blood pressure cut-offs than European guidelines, creating a 10 mm Hg difference in office measurements and 5 mm Hg in ambulatory and home measurements.
