P2.45 Evaluation of Central Blood Pressure and Augmentation Index in Patients with Isolated Ambulatory and Isolated Office Hypertension: The Vobarno Study

Different BP patterns have been identified by the use of office and 24 hours BP measurement: sustained normotension (NT), isolated office hypertension (IOH), isolated ambulatory hypertension (IAH) and hypertension (HT). Pulsewave analysis has been proposed for evaluation of central BP; “augmentation index” (AIx) is an accepted indirect index of arterial stiffness. Aim of our study was to assess the relationships between PWA and BP patterns in a general population in Northern Italy. Methods In 242 untreated subjects (-age 54±9 yrs, BMI 25±4, 47% males) radial artery applanation tonometry and PWA were used to derive central aortic pressures and AIx. All subjects underwent laboratory examinations and clinic and 24 h BP measurement.-Subjects were divided into subgroups: NT (office BP
