超声心动图评价慢性心功能衰竭患者左心功能的临床价值

目的探讨超声心动图评价慢性心功能衰竭患者左心功能的临床价值。方法对我院在2011年1月～2012年1月收治的153例慢性心功能衰竭2-4期的患者和48例作为对照组正常体检的人群，利用超声心动图对其左室射血的分数、舒张期血流峰值和短轴缩短率进行对比分析，探讨超声心动图评价慢性心功能衰竭患者左心功能的临床价值。结果 三组患者左心室和左心房增大的发生率之间的差异具有统计学意义．慢性心功能衰竭患者心脏的结构变化和心功能的等级之间有密切的联系。患者左心功能指标明显比正常人低，说明慢性心功能衰竭患者左心功能的改变，与对照组相比具有统计学意义。患者的短轴缩短率和对照组之间的对比无统计学意义。结论应用超声心动图对慢性心功能衰竭患者的左心功能进行评价，实际的应用价值较高，值得在临床上被广泛推广。

Clinical value of ultrasound echocardiography in evaluation of left heart function of patients with chronic heart failure

Objective To investigate the clinical value of the ultrasound echocardiographic evaluation of the left heart function of patients chronic heart failure. Methods The 153 patients with stage-2 to stage-4 chronic heart failure admitted in our hospital from January 2011 to January 2012 were selected and 48 healthy people were selected as the control group. The left ventricular ejection fraction, diastolic blood flow peak and shortening fraction were compared and analyzed using the ultrasound echocardiography. The clinical value of ultrasound echocardiographic evaluation of the left heart function of patients with chronic heart failure was investigated. Results Comparative analysis showed that the difference between the left ventricular enlargement incidence.and the left atrial enlargement incidence in the three groups had significant statisti- cally and that the cardiac structural change and the cardiac function degree of patients with chronic heart failure had close correlation. The left heart function parameters of the patients were significantly lower than those of healthy people, indicat- ing the left heart function change of patients with chronic heart failure,with statistical significance. The patients and the control group were not significantly different in the shortening fraction. Conclusion Ultrasound echocardiographic evalua- tion of the left heart function of patients with chronic heart failure has high application value, thereby worthy of wide clin- ical promotion.
