Background Arterial stiffness is increasingly recognized as a predictor of cardiovascular events but there is no method suited to calculate the arterial stiffness in 3-D. Methods We measured 6 pairs of diameter and thickness of the right and the left carotid artery of normal tension patients and their systolic and diastolic tensions. Then we calculate the arterial stiffness by introducing an hyper-elastic model in 3-D. Results Measurement of deformation of the carotid artery on normal tension patients allows us to determine the average arterial stiffness of 474 kPa compared to 808 kPa recently published "Carotid and Aortic Stiffness : Determinants of Discrepancies ”, Stephane Laurent et als, Hypertension 47; 371-376 (Beaujon Hospital / Pr Leseche July 23, 2009) Conclusions Our 3-D hyper-elastic model takes into account the thickness and the incompressibility of the biological tissues.
