A research on the aortic distensibility in patients with coronary artery disease / 医学研究生学报

ABSTRACT

0.05].Sao and Eao was significantly different between CHD group and the control group,but Aao has not significant different.③Sao positively correlated with ascending aortic distensibility coefficient(D)(r=0.73,P=0.03),and negatively correlated with aortic stiffness(?)(r=-0.68,P=0.03).Conclusion:Elastic properties of the aorta can directly be assessed by measuring the movements in the upper wall of the aorta with DTI.Reduced aortic S-velocity is significantly correlated with Ascending aortic distensibility coefficient(D) and stiffness index beta(?),which are important factors in assessing the changes of the aortic distensibility.
