摘　　要：目的　评价高血压病患者左心房射血力 (LAEF)改变及其影响因素。方法　应用多普勒超声结合二维超声技术 ,测定 2 2 8例高血压病患者和 2 2 3例正常健康者LAEF及左房射血力指数 (LAEFI) ,并分析其主要影响因素。结果　高血压病组LAEF、LAEFI、LVMI、TPR、IVSd、LVPWd等与正常组比较 ,均有显著性差异 (P <0 0 0 1)。以LAEFI =0 15 2 2N/m2 (正常组LAEFI均值 +2倍标准差 )将高血压病组分为两个亚组 ,两组间年龄、LVMI、LAPVI、IVSd有显著性差异 (P <0 0 5 )。结论　多普勒超声心动图测定左心房射血力 ,无创而易行 ,能够较好地评价左心房功能。高血压病患者左心房射血力显著高于正常人。年龄LAPVI、LVMI与左心房射血力呈显著正相关。Objective To investigate the change of left atrial ejection force and its determinants in patients.Methods by Using Doppler and two-dimensional echocardiograph,LAEFI was measured in 228 patients with essentienal hypertension and 223 normal subjects.Results LAEF、LAEFI、LVMI、TPR、LVPWd was significantly different between hypertensive groups and normal groups(P<0 001),Taking LAEFI=0.1522N/m 2(the mean±2SD of LAEFI of the normal subjects),the hypertensive groups was divided into two subgroups,the age LAPVI LVMI and IVSd was significantly different between two subgroups(P<0 05).Conclusion To evaluate AEF with Doppler echocardiograph is noninvasive and easy and accurately.The LAEF and LAEFI of hypertensive groups are larger than that of control groups.
