Aim To understand the aortic function in the old patients with arteriosclerosis. Methods Aortic elastic property were examined by echocardiography in the 56 cardiovascular old patients and in 60 negative old man. Results There was no significant difference in the diameter of aortic ascending and of abdominal arota between test group and control group (P>0.1), but the clistensibility of aorta in the patients subsides (P<0.001) and the stiffness index rises remarkably. Conclusions There was aclose relationship in the cardiovascular old patients between the aortic elastic property subsidence with the pulse pressure difference (△P), with the diameter difference of aorta(△d)and with other factors. So that the target of aortic elastic property is one of the important aspects in the diagnosis of the old men arteriosclerosis.
