Abstract

Abstract : Background and method: Measurement of 'unattended' blood pressure (BP) may reduce or eliminate the 'white-coat effect'. Despite the possible advantages of this approach for BP measurement, only few studies analysed the relationship between unattended BP and cardiovascular events or with hypertension-mediated organ damage (HMOD). The aim of our study was to evaluate the relationship between 'attended' or 'unattended' BP values and carotid-femoral pulse wave velocity (PWV) in 285 individuals undergoing a visit and assessment of arterial stiffness at an ESH Excellence Centre. Unattended BP (measured with the patient alone in the room, with an oscillometric device programmed to perform three BP measurements, at 1-min intervals, after 5 min) and attended BP were measured with the same device, on the same day of the measurement of PWV, in a random order. Results: Mean age was 63 ± 13 years, mean BMI 26 ± 4, 47% were women, 76% had hypertension (55% treated). Systolic unattended BP was lower than attended SBP (124.4 ± 14.3 vs. 130.9 ± 16.1 mmHg). PWV was similarly correlated with attended and unattended SBP values ( r = 0.428 and r = 0.404, P < 0.0001, respectively). No difference for the prediction of increased arterial stiffness was observed at receiver operator curves (ROCs) analysis [attended SBP area under the curve (AUC) 0.665, 95% confidence interval (95% CI) 0.607–0.720 vs. unattended SBP: AUC 0.651, 95% CI 0.593–0.706, P for the comparison = ns]. Conclusion: Attended and unattended BP values are similarly correlated with PWV, the gold standard measure of arterial stiffness. These findings may provide further information on the clinical value of unattended BP.
