摘要: Abstract Manual measurement of blood pressure (BP) in the office (MOBP) is inferior accuracy when compared with ambulatory BP measurements (ABPM) since it misses white coat and masked effects on BP. BpTRU, an automated device (AOBP), has been reported to reduce effect. We performed a retrospective review diagnostic MOBP (taken by trained nurse clinical hypertension) AOBP using Bland-Altman method hypertensive patients referred Renal Hypertension Clinic. In 329 patients, 95% limits agreement between systolic ABPM were −31 mm Hg 33 mm for −27.8 mm 37.4 mm Hg. The bias was 4.9 mm (95% confidence interval, 3.0–6.6 mm Hg) whereas −3.2 −1.3 −5.0). did not improve treatment relevant classification errors (28% vs. 23%; P = .052). Our data support findings others showing that improves, but does eliminate, increased detection effect appears related systematic downward BpTRU. As result, undermined
