摘要
目的分析心脏彩超在诊断慢性心力衰竭时的作用以及左室诊断多病因心力衰竭的临床应用意义。方法应用心脏彩超测量76例充血性左心衰竭患者左室射血分数(LVEF)(双平面Simpson法测量)、左心室舒张末期内径(LVDd)、左心房内径(LAD),并根据EF值分为正常组与降低组,对治疗前后EF值的变化进行分析。结果正常组与降低组治疗前后EF值对比、降低组的治疗前后EF值对比差异具有统计学意义,P<0.05,正常组治疗前后EF值差异无统计学意义,P>0.05。结论心脏彩超检查的左室射血分数对多病因心力衰竭的诊断无特异性,不能作为单一确诊标准,但可以作为临床治疗过程中的可信监测指标。
Objective To analyze the role of color doppler echocardiography in the diagnosis of chronic heart failure and its clinical significance of left ventricular ejection fraction in diagnosis of heart failure due to multiple causes. Methods By use of echocardiography, we measured 76 patients with congestive heart failure in terms of left ventricular ejection fraction （LVEF） （biplane Simpson method）, left ventricular end--diastolic diameter （LVDd）, and left atrial diameter （LAD）. According to EF values, patients were divided into normal value group and lower value group. The changes of EF values before and after treatment were analyzed in this work. Results The Compared the EF value in normal group and lower group before and after treatment, the difference in EF value inlower group before and after treatment EF was statistically significant （ P 〉0.05）, whereas, the difference in EF values in the normal group before and after treatment was not sig- nificant difference （ P 〉0.05）. Conclusion Left ventricular ejection fraction by cardiac ultrasound is unspecific for the diagnosis of heart failure due to multi--factors. It can not be taken as a single diagnostic criteria, but, can be used as a re- liable indicator for monitoring the clinical treatment process.
