摘要
目的应用常规超声心动图及应变率技术对高血压患者不同舒张功能状态对心房影响功能进行分析.方法选取原发性高血压患者97例,正常对照组30例,使用二维超声心动图及应变率技术按高血压组左室舒张功能进行分组,测量计算左房前后径、左房面积指数、左房容积指数及房间隔应变率参数,比较组间各参数的差异性.结果高血压左室舒张功能"假性正常化"患者,其左房面积指数较舒张功能正常组显著增大(P<0.05),房间隔应变率指数SRe减低,Sa增大(P<0.05).结论应用SRe、Sa值结合左房面积指数等来判断高血压患者左室舒张功能不全,比传统的二尖瓣血流频谱E/A<1更准确,可以避免舒张功能"假性正常化".
Objective To explore the effects of various left ventricular diastolic state on atrial function in patients with hypertension by diastolic state by using echocardiography and strain rate analyzing.Methods 30 healthy adults（Control Group,16 men,14 women）and 97 hypertensive patients（50 men,47 women） were selected in this study.The hypertensive patients were further divided into 4 groups based on diastolic function classification.General parameters were measured： left atrial diameter（LAD）,mitral tricuspid annular early diastole（E）and late diastole（A）inflow velocities,left atrial area index and strain rate imaging parameters.The difference in these parameters among all groups.Results Left atrial area index of hypertention patients with pseudo-normal left ventricular diastolic function was higher than that of patients with normal left ventricular diastolic function（P0.05）.Strain rate index of interatrial septum SRe was dencreased,and Sa was increased（P0.05）.Conclusion Sa and SRe of septum combined with left atrial area index is superior to E/A in evaluating left ventricular diastolic function in hypertensive patients,and can avoid pseudo-normal diastolic function.
