心脏彩超左室射血分数在老年多病因心力衰竭中的临床研究

Clinical Study of Left Ventricular Ejection Fraction (LVEF) with Color Doppler Ultrasound in Senile Multi-Cause Heart Failure

目的:探究心脏彩超左室射血分数在老年多病因心力衰竭应用价值。方法:抽选某院接收的多病因心力衰竭患者76例,平均将患者分为研究组与参照组各38例。左心室射血分数正常为研究组,左心室射血分数异常患者为参照组,比较其治疗前后患者左心室射血分数变化与其临床疗效。结果:治疗前研究组左心室射血分数显著高于参照组(P<0.05),治疗后研究组分数与治疗前相比差异不显著(P>0.05);而参照组患者左心室射血分数明显改善,与治疗前相比差异显著(P<0.05),同时与研究组相比差异仍显著(P<0.05);研究组治疗总有效率97.4%显著高于参照组治疗总有效率76.3%(P<0.05),差异存在统计学意义。结论:心脏彩超左室射血分数水平可作为心功能评定相关指标,并对治疗效果具有一定监测价值,值得临床推广与应用。

Objective:To study the application value of left ventricular ejection fraction(LVEF)with color Doppler ultrasound in elderly patients with multi-cause heart failure.Methods:76 patients with multi-cause heart failure were selected and divided into study group(38 cases)and reference group(38 cases).Patients with normal left ventricular ejection fraction were the study group,while those with abnormal left ventricular ejection fraction were the reference group.The changes of LVEF before and after treatment and their clinical efficacy were compared.Results:The left ventricular ejection fraction of the study group was significantly higher than that of the reference group before treatment(P<0.05).The left ventricular ejection fraction of the reference group was significantly improved,with a significant difference compared with that before treatment(P<0.05).At the same time,compared with the study group,the difference is still significant(P<0.05);The total effective rate in the study group was 97.4%higher than that in the reference group 76.3%(P<0.05),and the difference was statistically significant.Conclusion:The left ventricular ejection fraction level in the heart of the heart can be used as the relevant index of the heart function evaluation,and has a certain monitoring value for the treatment effect,which is worthy of clinical popularization and application.
