实时三维超声心动图评估左室射血分数正常的老年高血压患者左心房容积与功能
Assessment of left atrial volume and function by real-time three dimensional echocardiography in elderly hyper-tensive patients with normal left ventricular ejection fraction
摘要
Abstract
Objective To evaluate the change of left atrial volume and function in elderly hypertensive patients with normal left ventricular ejection fraction.Methods Seventy-nine elderly hypertensive patients were divided into LVH group(38 patients with left ventricular hypertrophy)and NLVH group(41 patients without left ventricular hypertro-phy).Control group consisted of 28 normal subjects.Index of echocardiography,including left atrial diameter(LAD),mi-tral peak flow velocity during early and late diastole (E,A),ratio of E /A,peak velocities of interventricular septum sites at mitral annulus during early and late diastole (E′,A′),and ratio of E /E′,maximum left atrial volume(LAVmax),min-imum left atrial volume(LAVmin),volume before contraction(LAVp)of left atrial were acquired,left atrial passive and active ejection fraction (LAPEF,LAAEF)were measured in all the subjects.Results Compared with normal group,E /E′,LAVmax,LAVp,LAAEF of NLVH and LVH groups were significantly increased(P <0.05).LAD and LAVmin of LVH group were significantly increased(P <0.05).E /A and LAPEF of LVH group were significantly decreased(P <0.05).Conclusions RT-3DE provides a new method to evaluate left atrial volume and function.Left atrial function are impaired in NLVH group of elderly hypertension patients.The damage degree of left atrial function and LV diastolic function is more severe in LVH group.关键词
