[Change in ambulatory arterial stiffness index with advancing age and the correlation with 24 hours pulse pressure in healthy individuals].

Objective: Ambulatory arterial stiffness index (AASI) has been recently proposed to reflect the dynamic relation between diastolic and systolic blood pressure throughout the whole day. The aim of our study was to investigate the change in AASI with advancing age and the correlation with 24 hours pulse pressure (24 h PP) in healthy individuals.

Methods: 246 healthy subjects [mean age (59.
