【摘要】：目的探讨二维斑点追踪超声心动图在老年心力衰竭患者诊断中的应用价值。方法 2012年10月至2014年10月在该院就诊的老年心力衰竭患者49例设为观察组。同期在该院接受治疗的非心力衰竭的老年患者49例设为对照组。通过实时三维超声心动图测量两组被检人员的左心房主动射血分数(LAAEF)、左心房被动射血分数(LAPEF)、左心房整体射血分数(LAEF)、左心房最小容积(LAVmin)、左心房最大容积(LAVmax)以及左心房收缩前容积(LAVpre)水平,并且应用二维斑点超声技术测定各房壁的左心室舒张早期峰值平均应变率(m SRe)、舒张晚期峰值平均应变率(m SRa)以及收缩期峰值平均应变率(m SRs)水平。结果观察组LAAEF、LAPEF、LAEF都低于对照组(P0.01)。观察组LAVmin、LAVmax、LAVpre都高于对照组(P0.01)。较对照组而言,观察组的m SRs、m SRe下降,m SRa上升(P0.01)。结论老年心力衰竭患者的左心房功能均存在不同程度的下降,二维斑点追踪超声心动图能够及时准确地反映老年心力衰竭患者左心房功能发生的变化,从而有利于早期展开治疗。
[Abstract]:Objective to evaluate the value of two-dimensional dot-tracing echocardiography in the diagnosis of elderly patients with heart failure. Methods from October 2012 to October 2014, 49 elderly patients with heart failure were treated as observation group. At the same time, 49 elderly patients with non-heart failure received treatment in the hospital as control group. Left atrial active ejection fraction (LAAEF), left atrial passive ejection fraction (LAPEF), left atrial global ejection fraction (LAEF), left atrial minimum volume (LAVmin), left atrial maximum volume (LAVmax) and left heart were measured by real-time three-dimensional echocardiography. Atrial presystolic volume (LAVpre) level, The mean peak strain rate (mSRe), peak strain rate (mSRa) and peak systolic strain rate (mSRs) of left ventricle were measured by two-dimensional speckle ultrasound. Results the LAAEFA LAPEFL LAEF in the observation group was lower than that in the control group (P 0.01). Both LAVmin and LAVmaxLAVpre in the observation group were higher than those in the control group (P0.01). Compared with the control group, the mSRsm SRe decreased and mSRa increased in the observation group (P0.01). Conclusion the left atrial function of elderly patients with heart failure is decreased to some extent. Two-dimensional dot-tracing echocardiography can accurately reflect the changes of left atrial function in elderly patients with heart failure. Thus, it is beneficial to the early development of treatment.
