Abstract

Cross-sectional area compliance (CC) and distensibility (DC) in the ascending and descending aorta and the average pulse wave velocity (PWV) along the descending section of the thoracic aorta were studied in a group of young versus old normotensive subjects using magnetic resonance imaging (MRI). CC and DC correlated stronger with age in the ascending aorta than the descending aorta. Aging-related alteration of the functional properties of the aortic wall, have a different pattern in the ascending versus the descending aorta.
