摘要
目的:探讨心脏彩超对高血压左心室肥厚伴左心衰竭的临床诊断意义。方法:选择高血压左心室肥厚伴左心衰竭患者50例为观察组,选择同龄正常人群50例为对照组,两组均行心脏彩超检查进行比较。结果:观察组较对照组左室后壁厚度(LVPWd)厚,左室舒张末期内径(LVDd)、左房内径(LADd)宽,左室射血分数(LVEF)低,舒张晚期峰值流速(A峰)快、舒张早期峰值流速(E峰)慢、E/A值低,差异有统计学意义(P<0.05);观察组心功能分级越高LVPWd越厚,LVDd、LADd越宽,LVEF越低,A峰越快、E峰越慢、E/A值越低,差异有统计学意义(P<0.05)。结论:心脏彩超对诊断高血压左心室肥厚伴左心衰竭,评估心功能有显著临床价值。
Objective：To investigate the clinical diagnostic significance of echocardiography to left ventricular hypertrophy complicated with left ventricular failure.Methods：50cases with left ventricular hypertrophy complicated with left ventricular failure were selected as the observation group,50 cases of the normal population of the same age were selected as the control group,they underwent echocardiography for comparison.Results：1.LVPWd of the observation group were thicker than the control group,diference in LVDd,LADd wide,LVEF low,A quick peak,E peak slow,low E/A values were significant（P〈0.05）;2.The higher NYHA classification of the observation group,the thicker LVPWd is,the wider LVDd and LADd are,lower the LVEF is,and sooner the A peak sooner,but slower the E peak,the lower E/A value is,the difference were all significant（P〈0.05）.Conclusion：Echocardiography is valuable for the diagnosis of left ventricular hypertrophy complicated with left ventricular failure,and also for the assessment of cardiac function.
