摘　　要：为分析心脏超声对心力衰竭患者左室舒张功能的评价效果及其可靠性,本文选取98例心力衰竭患者为实验组,以98例健康人为对照组进行研究。两组均接受了心脏超声检查,结果显示,实验组患者的左房内径(LAD)、室间隔厚度(IVST)、左室舒张末期内径(LVDd)、左室收缩末期内径(LVDs)、左室后壁厚度(LVPWT)均较对照组高(P<0.05);实验组E峰减速时间(DT)较对照组低,二尖瓣舒张早期E峰速度/舒张晚期A峰速度(E/A)、二尖瓣环间隔部舒张早期峰速度(Esep)、二尖瓣环侧壁部舒张早期峰速度(Elat)、二尖瓣舒张早期E峰速度/二尖瓣环舒张早期运动峰速度(E/Ea)较对照组高(P<0.05);实验组E/Ea≥15的患者,其LVDd、左心射血分数(LVEF)、E/A值较E/Ea<15的患者高,DT值则较E/Ea<15的患者低(P<0.05)。本研究证实心脏超声可通过左心形态、左室舒张功能检测对心力衰竭左室舒张功能异常情况进行准确评估,并判断其异常程度。In order to investigate the echocardiographic evaluation of left ventricular diastolic dysfunction and its reliability in patients with heart failure,this study selected 98patients with heart failure as the test group,and 98healthy people as the control group.Both groups underwent echocardiography and the results were compared.The results showed that the left atrial dimension(LAD),interventricular septal thickness(IVST),leftventricular end-diastolic diameter(LVDd),left ventricular end-systolic dimension(LVDs)and left ventricular posterior wall thickness(LVPWT)in the test group were all higher than those in the control group(P<0.05).Compared with control group,the deceleration time(DT)of test group were lower,while the mitral valve diastolic early E peak speed/diastolic late A peak speed(E/A),early diastolic velocity of mitral annulus from septal(Esep),early diastolic velocity of mitral annulus from lateral(Elat),the mitral valve diastolic early E peak velocities/mitral valve diastolic early peak velocities(E/Ea)were higher(P<0.05).The LVDd,left ventricular ejection fractions(LVEF)and E/A of the patients with E/Ea≥15in the test group were higher than those with E/Ea<15,and DT of the patients with E/Ea≥15was lower than those with E/Ea<15(P<0.05).In conclusion,the left ventricular diastolic function and left ventricular diastolic function can be accurately evaluated by cardiac ultrasound.
