Evaluation Effect of Strain and Strain Rate Imaging on Left Atrial Function of Patients with Chronic Heart Failure

目的探讨应变、应变率成像技术对慢性心力衰竭患者左心房功能的评估作用。方法选取2013年10月至2018年10月我院收治的慢性心力衰竭患者30例作为研究组,选取同期我院的体检者30例作为对照组,比较两组的超声指标和左房各壁应变达峰时间指标。结果研究组的左房每搏量、左房最大容积、左房最小容积均显著高于对照组,且左房射血分数显著低于对照组,差异均有统计学意义(P <0.01)。研究组的SSR、 ESR、 ASR均明显低于对照组,差异有统计学意义(P <0.01)。结论与正常人相比,慢性心力衰竭患者的左心房功能出现减退。应变、应变率成像技术在慢性心力衰竭患者左心房功能的评价中具有良好的应用效果。

Objective To explore the evaluation effect of strain and strain rate imaging on left atrial function of patients with chronic heart failure. Methods 30 cases of patients with chronic heart failure admitted to our hospital from October 2013 to October 2018 were selected as study group, and 30 people with physical examination in our hospital at the same period were selected as control group. The ultrasound indicators and the peak strain time of left atrial walls of the two groups were compared. Results The left atrial stroke volume,maximum left atrial volume and minimum left atrial volume of the study group were significantly higher than those of the control group, and the left atrial ejection fraction was significantly lower than that of the control group, with statistical differences(P<0.01). The SSR, ESR and ASR of the study group were significantly lower than those of the control group(P<0.01). Conclusions Compared with the normal people,the left atrial function of patients with chronic heart failure decreases. Strain and strain rate imaging has good application effect in the evaluation of left atrial function of patients with chronic heart failure.
