Background: Recent studies have reported that prehypertension is associated with increased values of common carotid artery intima-media thickness (CCA-IMT). The aim of this study was to assess the impact of daytime ambulatory blood pressure (BP) levels on the association of prehypertension with CCA intima-media thickening in prehypertensive subjects.
Methods: A total of 807 subjects with office systolic BP<140 and diastolic BP<90mmHg, underwent 24h ambulatory BP (ABP) monitoring and carotid artery ultrasonographic measurements.
