Aortic
compliance (AC) can be evaluated noninvasively and its reduction with age in
normals has been demonstrated with MRI. Decreased aortic compliance (AC) is
associated with aging, systolic hypertension and left ventricular diastolic
dysfunction. Aortic pulse wave velocity (PWV) often serves as a surrogate to
AC, and it can be evaluated using a single breath-hold phase contrast imaging
technique. Its age correlation has been demonstrated by both MR and echo
studies in normal volunteers. We evaluated the aortic compliance and their
relationship to age, as well as the other biomedical parameters in 189 normal
volunteers.
