Objective To investigate the faction of left ventricular diastolic function to the hemodynamics of carotid artery in Patients with hypertension of different age groups.Methods 608 cases of essential hypertension divided into three groups by age: Young-aged, middle-aged and elderly group.Measure the E、 A of the diastolic mitral flow and the hemodynamics of carotid artery with Doppler echocardiography.Result Compared with the three age group of the essential hypertension: when E/A>1, some of the parameter of hemodynamics such as PSV、 PI、 RI were depressed along with the age growth in both CCA and VA;when E/A<1, with the age growth, PSV were depressed in both CCA and VA, and ESV also does in CCA.PI and RI were rised in both CCA and VA.Compared with the groups between E/A>1 and E/A<1, EDV were depressed and the PI、 RI were rised in the elder-aged group of the three groups of the carotid artery.Conclusion When the left ventricular diastolic function were decreased , Vascular compliance were decrease and the resistance of blood flow rised along with the age growth.
