心脏彩色多普勒超声在诊断多病因性慢性心力衰竭的临床应用价值探讨

目的：研究探讨分析心脏彩色多普勒超声在诊断慢性心力衰竭及左室诊断多病因心力衰竭的效果，分析其诊断价值。方法2012年1月至2014年1月收治的100例慢性心力衰竭患者，首先用心脏彩色多普勒超声将全部患者进行测量，测出他们的左心室射血分数（LVEF），左心室舒张末期内径（LVDD），左心房内径（LAD），再根据左心室的射血分数将100例的患者分为2组，即对照组和试验组，前者射血分数（EF）正常，后者EF降低，在对患者进行治疗前和治疗后，均测试1次LVEF，进行比较分析。结果试验组治疗前后的LVEF值差异无统计学意义，对照组治疗前后LVEF值差异有统计意义，而将二者对比，其差异有统计学意义。结论心脏彩色多普勒超声检查诊断慢性心力衰竭脏及多病因心力衰竭不能用来确诊，但是在监测临床治疗过程中具有重要的作用。

The clinical application of heart color ultrosonography in the diagnosis of chronic heart failure and left ven-tricular

Objective To study the analysis in the diagnosis of chronic heart failure to diagnose more causes the effect of heart failure, analyze its diagnostic value. Methods Between January 2012 and January 2014, 100 cases of patients with chronic heart failure underuent heart color untrosonography, and their left ventricular ejection fraction （LVEF）, left ventricular end-diastolic diameter （LVDD）, left atrium diameter （LAD） were measured, according to left ventricular ejection fraction, 100 cases of patients can be divided into two groups, namely the control group and ex-perimental group, the former EF was normal, the latter EF was lower, The LVEF was compared before and after treat-ment. Results There was no significance in The experimental group before and after treatment, while value have sta-tistical significance, and compare the two group, There has the obvious statistical significance. Conclusion Heart col-or untrosonography can be used in the diagnosis of chronic heart failure, but can′t be used to diagnose heart failure, they play an important role in the process of monitoring the clinical treatment.
