hypertension requires integration of home or ambulatory blood pressure monitoring
(ABPM), whereas routine measurements made in the clinical setting should be used
If there is a disparity in category between the systolic and diastolic pressures, the
The following diagnostic criteria were suggested by the 2017 ACC/AHA guidelines; meeting
one or more of these criteria using ABPM qualifies as confirmation of hypertension (
table 3
) [

].
We find the daytime (awake) average of ≥130 mmHg systolic or ≥80 mmHg diastolic to be
the most useful of these definitions.
Home readings correlate more closely with the results of daytime ambulatory
measurements than with blood pressures that are typically obtained in the clinician's office
(ie, using a manual cuff and stethoscope or using an oscillometric device with the care
provider present in the room). We believe that hypertension can be confirmed by repeated
home blood pressure readings that average ≥130/≥80 mmHg.
Guidelines from the ESC/ESH, ISH, and NICE differ somewhat from the ACC/AHA guidelines;
using ambulatory or home blood pressures, the ESC/ESH, ISH, and
NICE
define
hypertension as a 24-hour mean of ≥130 mmHg systolic or ≥80 mmHg diastolic or a
daytime mean (or an average of home readings) that is ≥135 mmHg systolic or ≥85 mmHg
diastolic (
table 2
) [
5-7
].
Both white coat hypertension and masked hypertension are conditions that can only be
defined based upon the comparison of out-of-office blood pressure measurements (ABPM
and home) with office-based blood pressure measurements.
