Age-associated changes in arterial elastic properties in children.

Unlabelled: Age-associated changes in pulsatile components of the arterial system in normal children have not previously been studied. The purpose of the present study was to establish reference ranges for age-associated changes in arterial pulsatile properties in children. Arterial compliance (C(A)) and stiffness of the proximal aorta were estimated from data obtained by cardiac catheterisation in 112 paediatric patients (age range, 6 months to 20 years) who were considered to have normal systemic vascular beds.
