目的:探究心脏超声影像对重症急性左心收缩功能不全患者生存状况的评估价值。方法:选取2014年1月至2015年12月接受治疗的108名重症急性左心收缩功能不全患者作为观察组,根据超声影像检查分为左心弥漫抑制(33例)、冠状动脉相关节段抑制(40例)、非冠状动脉相关节段抑制(35例),选取40名健康体检者作为对照组,分析多普勒超声影像检测结果和不同患者的病因,对患者持续用药时间、住ICU时间以及病死率进行记录。结果:多普勒超声影像检测分析显示观察组E峰值、A峰值以及E/A值低于正常组,差异具有统计学意义(P<0.05);左心弥漫抑制患者患有感染性休克为23例,所占比例为69.70%(23/33);冠状动脉相关节段抑制患有缺血性心肌病患者为32例,所占比例为80.0%(32/40);非冠状动脉相关节段抑制患者以应激性心肌病为主,所占比例为54.28%(19/35);重症急性左心收缩功能不全各组患者住ICU时间、机械通气时间、使用强心药物时间以及28d病死率比较,差异无统计学意义(P<0.05);结论:心脏超声影像能够对重症急性左心收缩功能不全患者生存状况做出有效评价,具有良好的临床应用价值。
Objective: To investigate the value of echocardiographic evaluation of the survival of patients with severe acute left ventricular systolic dysfunction. Methods: One hundred and eighty patients with severe acute left ventricular systolic dysfunction who were treated from January 2014 to December 2015 were selected as the observation group. According to the ultrasound examination, diffuse left ventricular suppression (33 cases), coronary artery related segment suppression (40 cases) and non-coronary artery related segments (35 cases). Forty healthy subjects were selected as the control group. The results of Doppler ultrasonography and the etiology of different patients were analyzed. The duration of medication, ICU time As well as the case fatality rate recorded. Results: Doppler ultrasound imaging analysis showed that the peak E, peak A and E / A in observation group were lower than those in normal group (P <0.05); patients with diffuse left ventricular suppression had septic shock in 23 Cases, accounting for 69.70% (23/33); coronary artery-related segment inhibition in patients with ischemic cardiomyopathy in 32 cases, the proportion was 80.0% (32/40); non-coronary artery related segments In patients with severe acute left ventricular systolic dysfunction, ICU duration, duration of mechanical ventilation, time to use cardiotomy drugs, and mortality at 28 days were significantly higher in patients with severe acute left ventricular systolic dysfunction than those in patients with stress cardiomyopathy (54.28%, 19/35) (P <0.05). CONCLUSION: Echocardiography can effectively evaluate the survival of patients with severe acute left cardiac systolic dysfunction and has good clinical value.
