Beschreibungen/Notizen

• Compared with conventional blood pressure (CBP) measurements, automated techniques are more reproducible, not subject to digit preference or observer bias and are increasingly being used to diagnose white-coat hypertension. Self-measurement of the blood pressure at home (HBP) is less expensive than ambulatory blood pressure monitoring (ABP), but needs further clinical validation. In 224 patients, we compared the BP values obtained by CBP, HBP and ABP. The thresholds to diagnose hypertension were ≥140/≥90 mm Hg for CBP and ≥135/≥85 mm Hg for ABP or HBP. Indexes reflecting left ventricular mass (LVM) were calculated from ECGs (n=221) or echocardiograms (n=39). Mean systolic/diastolic CBP, HBP and ABP were 160.5/101.2 mm Hg, 146.4/91.3 mm Hg and 148.5/93.0 mm Hg, respectively. The white-coat effect was 2.1/1.7 mm Hg larger on HBP compared with ABP (14.1/9.9 v 12.0/8.2 mm Hg; P≤.01). The correlation coefficients between the white-coat effects based on HBP and ABP were 0.67 systolic and 0.68 diastolic (P<.001). HBP and ABP gave concordant results in 189 patients (84.4%) of whom 173 had sustained hypertension and 16 had white-coat hypertension. Systolic HBP and ABP, but not systolic CBP, correlated positively and significantly with LVM indexes. Under standardized conditions of measurement, the white-coat effects based on HBP and ABP are correlated, but HBP and ABP identify slightly different subsets of white-coat hypertensive patients. In contrast to CBP, both HBP and ABP correlated closely with LVM indexes.
