心脏彩超和左心室射血分数在多病因慢性心力衰竭诊断中的应用价值

The value of color Doppler echocardiography and left ventricular ejection fraction in the diagnosis of chronic heart failure

目的分析心脏彩超和左心室射血分数(LVEF)在多病因慢性心力衰竭诊断中的临床价值。方法纳入病例是高州市人民医院2017年1月~2019年12月收治的96例慢性心力衰竭患者,根据LVEF分组,将LVEF正常的47例患者作为参照组,将LVEF异常的49例患者作为观察组,所有患者均进行心脏彩超(1-5MHz的探头频率)检查,对比两组左心室舒张末期内径(LVEDD)、左心室收缩末期内径(LVESD)、LVEF,分别对比两组治疗前、治疗后LVEDD、LVESD、LVEF。结果观察组LVEDD、LVESD[(60.25±2.54)mm、(53.26±2.77)mm]均显著比参照组[(65.26±3.26)mm、(56.82±3.33)mm]低,观察组LVEF(42.14±3.99)%显著比参照组(32.62±3.26)%高,差异均具有统计学意义(t=8.3754、5.6820、12.8255,P均<0.001)。观察组治疗后LVEDD、LVESD[(59.26±2.62)mm、(52.26±2.46)mm]显著比治疗前[(65.26±3.44)mm、(56.82±3.33)mm]低,观察组LVEF[(43.57±2.95)%]显著比治疗前[(32.62±3.26)%]高,差异均具有统计学意义(t=9.7130、7.7099、17.4339,P均<0.001)。参照组治疗前LVEF、LVEDD、LVESD[(42.14±3.99)%、(60.25±2.54)mm、(53.26±2.77)mm]与治疗后[(43.01±3.82)%、(60.11±2.49)mm、(52.99±2.88)mm]比较,差异均无统计学意义(t=1.0798、0.2698、0.0632,P=0.2831、0.7879、0.6443)。结论心脏彩超和LVEF在多病因慢性心力衰竭诊断中,可准确评估患者病情、治疗效果等,且无创伤、操作方便,值得借鉴。

Objective To analyze the value of color Doppler echocardiography and left ventricular ejection fraction in the diagnosis of chronic heart failure.Methods From January 2017 to December 2019,a total of 96 patients with chronic heart failure admitted to the hospital were enrolled.The patients were divided into two groups according to left ventricular ejection fraction(LVEF).Among them 47 patients with normal LVEF were taken as the reference group,and 49 patients with abnormal LVEF were taken as the observation group.All patients underwent cardiac color photo examination(1-5MHz probe frequency),left ventricular end-diastolic diameter(LVEDD),left ventricular end-systolic diameter(LVESD),and LVEF were compared between the two groups before and after treatment.Results LVEDD and LVESD[(60.25±2.54)mm,(53.26±2.77)mm]in the observation group were significantly lower than those in the reference group[(65.26±3.26)mm,(56.82±3.33)mm],and LVEF(42.14±3.99)%in the observation group was significantly higher than that in the reference group(32.62±3.26)%with statistically significant differences(t=8.3754,5.6820,12.8255,P<0.001).After treatment,LVEDD and LVESD in the observation group were significantly lower than those before treatment[(59.26±2.62)mm,(52.26±2.46)mm],and LVEF(43.57±2.95)%in the observation group was significantly higher than those before treatment(32.62±3.26)%with statistical significance(t=9.7130,7.7099,17.4339,P<0.001).There was no significant difference in LVEF,LVEDd,LVESD[(42.14±3.99)%,(60.25±2.54)mm,(53.26±2.77)mm]in the reference group before and after treatment[(43.01±3.82)%,(60.11±2.49)mm,(52.99±2.88)mm](t=1.0798,0.2698,0.0632,P=0.2831,0.7879,0.6443).Conclusion In the diagnosis of chronic heart failure with multiple causes,color Doppler echocardiography and LVEF can accurately evaluate the patient's condition and treatment effect,and it is noninvasive and easy to operate,which is worth learning.
