The Relationship Between Artery Stiffness and Left Ventricular Diastolic Function in Patients With Multiple Cardiovascular Risks

Abstract

To evaluate the relationship between artery stiffness and left ventricular diastolic function. A total of 79 patients with multiple cardiovascular risks were recruited and divided into two groups according to the value of E/Em: diastolic dysfunctional group (E/Em≧10, n=25) and control group (E/Em<10, n=54). The arterial stiffness parameters of carotid artery and endothelium-independent dilation (EID) of brachial artery were evaluated by ET for two groups. The arterial stiffness parameters of carotid artery and EID of brachial artery in diastolic dysfunctional group were higher than that in controls (p > 0.05), and were associated to diastolic function parameters of left ventricular (p < 0.05). The arterial stiffness is closely related to the diastolic function of left ventricular, and maybe an important factor to impact on it. The increased arterial stiffness is useful in predicting left ventricular diastolic dysfunction in patients with multiple cardiovascular risks.
