If the visit 1 mean non-AOBP or AOBP SBP is >= 180 mm Hg and/or DBP is >= 110 mm Hg then hypertension is diagnosed (Grade D).
If the visit 1 mean non-AOBP SBP is 140-179 mm Hg and/or DBP is 90-109 mm Hg or the mean AOBP SBP is 135-179 mm Hg and/or DBP is 85-109 mm Hg, out-of office BP measurements should be performed before visit 2 (Grade C).
Home SBP values 135mmHg or DBP values 85mmHg should be considered to be elevated and associated with an increased overall mortality risk (Grade C).
