Relationship between arterial stiffness and unattended or attended blood pressure values

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.
