Correlation of left ventricular diastolic function on echocardiography and common carotid artery elasticity on ET imaging in hypertension patients / 中华医学超声杂志（电子版）

ABSTRACT

Objective To investigate the relationship between diastolic function of the left ventricle and common carotid artery (CCA) elasticity in patients with hypertension. Methods Forty-one primary hypertension patients and 31 healthy volunteers underwent echocardiography to obtain the indices of LV diastolic function and also echo tracking techniqne (ET) to obtain the CCA elasticity indices. The LV diastolic function indices included Ve (early diastolic peak velocity), Va (late diastolic peak velocity ), Ve/Va, Em (early diastolic mitral annular motive velicity), Am (late diastolic mitral annular motive velicity) and Em/Am. The indices of CCA elasticity included Ep (pressure-strain elasticity modulus), β(stiffness parameter), AC (arterial compliance), AI (augmentation index) and PWVβ (pulse wave velocity). Results Va was higher and Em, Ve/Va and Em/Am were lower in patients than that in the healthy , P＜0.05. Ep and PWVβ were higher in patients,P＜0.05. Am and Va were correlated positively with PWV β and Ep , respectively in patients, P＜0.05. Ve/Va was correlated positively with AC, and negatively with PWV β, P＜0.05 in patients. Em/Am was correlated negatively with β and PWV β in patients. Conclusions The LV diastolic function and common carotid artery elasticity were decreased in patients with hypertension. The decreased common carotid artery elasticity was along with the LV diastolic function decreased.
