| Abstract: | In SPRINT (Systolic Blood Pressure Intervention Trial), use of the Omron 907XL blood pressure (BP) monitor set at 5 minutes of antecedent rest to record BP produced an automated office BP value 7/6 mm Hg lower than awake ambulatory BP at 27 months. The authors studied the impact on automated office BP of setting the Omron 907XL to 0 minutes instead of 5 minutes of rest in patients with readings in the lower normal BP range, similar to on‐treatment BP in the SPRINT intensive therapy group. Patients (n = 100) in cardiac rehabilitation were randomized to three BP readings at 1‐minute intervals using an Omron 907XL BP device set for 5 or 0 minutes of antecedent rest. Mean (±standard deviation) automated office BP (mm Hg) after 5 minutes of rest (120.2 ± 14.6/66.9 ± 8.6 mm Hg) was lower (P < .001/P < .01) than without rest (124.2 ± 16.4/67.9 ± 9.1 mm Hg). When target BP is in the lower normal range, automated office BP recorded without antecedent rest using an Omron 907XL device should be higher and closer to the awake ambulatory BP, compared with readings taken after 5 minutes of rest. |
