心脏彩超左室射血分数与老年多病因心力衰竭的临床研究

Clinical study of cardiac color Doppler left ventricular ejection fraction and senile disease caused by heart failure

目的探讨心脏彩超左室射血分数在老年多病因心衰患者中的应用价值,总结临床诊断经验。方法选取我院2016年1月~2017年4月间收治的多病因心衰高龄患者共64例作为研究对象,将其随机均分为A、B组两组,每组均32例患者,A组为左室射血分数正常组,B组为射血分数降低组,所有患者均进行心脏彩超检查,每组患者平均测量3个心动周期,记录数值后取平均值,观察治疗前后患者左心室射血分数的好转及改变情况。结果治疗前,A组左心室射血分数(LVEF)显著高于B组。差异经t检验,证明存在统计学意义(P<0.05)。治疗后,A组左心室射血分数(LVEF)无明显变化,而B组左心室射血分数(LVEF)水平与治疗前相比,明显升高,但与A组左心室射血分数(LVEF)相比明显较低,差异有统计学意义(P<0.05)。治疗总有效率方面:A组为96.88%,B组为75.00%,差异有统计学意义(P<0.05)。结论临床对多病因心衰高龄患者采用心脏彩超诊断取得了较好的效果,该技术可准确评估患者的心脏功能,并对治疗效果有监测价值,故有进一步推广的价值。

Objective To explore the value of left ventricular ejection fraction of heart color Doppler ultrasound in elderly patients with heart failure, and to summarize the clinical diagnosis experience. Methods Sixty-four cases of senile patients with senile heart failure treated in our hospital from January 2016 to April 2017 were selected as the subjects of study. They were randomly divided into two groups, group A and group B, with 32 patients in each group, group A as normal left ventricular ejection fraction, and group B as group of ejection fraction. All patients were examined by echocardiography, and each group averaged 3 cardiac cycles. The average value was recorded and the improvement and change of left ventricular ejection fraction were observed before and after treatment. Results Before treatment, left ventricular ejection fraction(LVEF) in group A was significantly higher than that in group B. The difference was statistically significant(P < 0.05). After treatment, the left ventricular ejection fraction(LVEF) in group A did not change significantly, while the left ventricular ejection fraction(LVEF) in group B increased significantly compared with that before treatment, but it was significantly lower than that in group A(P < 0.05). The total effective rate of treatment was 96.88% in group A and 75.00% in group B, and the difference was statistically significant(P < 0.05). Conclusion The clinical diagnosis of heart failure in elderly patients with multifactorial heart failure has achieved good results. The technology can accurately assess the cardiac function of patients, and has a monitoring value for treatment effect, so it has the value of further promotion.
