The information above may be reinforced with videos available online. See Table 11 for HBPM targets. BP indicates blood pressure; and HBPM, home blood pressure monitoring. for monitoring out-of-office BP levels, and even the BP thresh- olds used to define hypertension with ABPM or HBPM read- ings. In addition, there are few data that address reproducibility of these hypertension profiles over time, with several studies suggesting progression of white coat hypertension and espe- cially of masked hypertension to sustained office-measured 4.4. Masked and White Coat Hypertension Recommendations for Masked and White Coat Hypertension References that support recommendations are summarized in Online Data Supplements 4, 5, and 6. COR LOE Recommendations IIa B-NR 1. In adults with an untreated SBP greater than 130 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.S4.4-1 S4.4-8 IIa C-LD 2. In adults with white coat hypertension, periodic monitoring with either ABPM or HBPM is reasonable to detect transition to sustained hypertension (S4.4-2,S4.4- 5,S4.4-7). IIa C-LD 3. 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 (S4.4-9,S4.4-10). IIa B-NR 4. 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 8,S4.4-11).
