ABSTRACT
Objective To investigate the correlation between normal ascending aortic elasticity and the left ventricular function by 256 slice iCT.Methods 105 subjects who underwent CTA and echocardiography inspection and diagnosed with normal coronary artery and without ascending aortic atherosclerosis were collected.Subjects were divided into three groups according to age and two groups according to gender respectively.Left ventricular function parameter values on CT were measured, including ESV,EDV,SV,EF,CO and MM.The aortic elasticity on CT and echocardiography was measured and calculated respectively on cross-sectional area at 15 mm above aortic valve.The relationship between ascending aortic elasticity and the left ventricular function was evaluated.Results Bland-Altman plot revealed that there was a good conformity between CT and echocardiography in measurement the value of ascending aortic elasticity(ICC=0.988,P<0.05).In different grougs of age,normal ascending aortic elasticity was positively correlated with EDV,ESV,SV,EF and negatively correlated with MM.There was no correlation with the CO.There was a negative relationship between aortic elasticity and age(r=-0.546,P<0.05)
