Recommendations
IIa B-NR In adults with an untreated SBP greater than130 mm Hg but less
than 160 mm Hg or DBP greater than 80 mm Hg but less than
100 mm Hg, it is reasonable to screen for the presence of white
coat hypertension by using either daytime ABPM or HBPM
before diagnosis of hypertension.
IIa C-LD In adults with white coat hypertension, periodic monitoring with
either ABPM or HBPM is reasonable to detect transition to
sustained hypertension.
IIa C- LD In adults being treated for hypertension with office BP readings
not at goal and HBPM readings suggestive of a significant white
coat effect, confirmation by ABPM can be useful.
IIa B-NR In adults with untreated office BPs that are consistently between
120 mm Hg and 129 mm Hg for SBP or between 75 mm Hg
and 79 mm Hg for DBP, screening for masked hypertension with
HBPM (or ABPM) is reasonable.
IIb C-LD In adults on multiple-drug therapies for hypertension and office
BPs within 10 mm Hg above goal, it may be reasonable to screen
for white coat effect with HBPM (or ABPM).
IIb C-EO It may be reasonable to screen for masked uncontrolled
hypertension with HBPM in adults being treated for
hypertension and office readings at goal, in the presence of target
organ damage or increased overall CVD risk.
IIb C-EO In adults being treated for hypertension with elevated HBPM
readings suggestive of masked uncontrolled hypertension,
confirmation of the diagnosis by ABPM might be reasonable
before intensification of antihypertensive drug treatment.
