Significance of left ventricular echocardiography in patients with coronary heart disease
冠心病患者应用心脏超声左心室造影的意义探析

摘要

目的 探究心脏超声左心室造影在冠心病患者中的应用效果。方法 选取本院在2021年9月-2022年11月期间收治的50例冠心病患者为研究对象，上述患者均采取介入治疗，患者于治疗前后采取心脏超声左心室造影，将其设为实验组。选取同期健康人群50例作为参考组，同样采取心脏超声左心室造影。比较两组EDV、ESV、SV、EF、LVEF、LVEDP、K值及T值指标情况。结果 实验组治疗前LVEF、LVEDP、K值及T值与参考组对比有明显差异，有统计学意义（P＜0.05），实验组治疗后与治疗前比较有明显改善，差异有统计意义（P＜0.05），实验组治疗后与参考组对比差异不明显，无统计学意义（P＞0.05）。实验组治疗前EDV、ESV、SV、EF指标于参考组比较有明显差异，有统计学意义（P＜0.05），实验组治疗后与治疗前比较有明显改善，差异有统计意义（P＜0.05），实验组治疗后与参考组对比差异不明显，无统计学意义（P＞0.05）。结论 在冠心病患者中采取心脏超声左心室造影具有重要的意义，特别是在患者采取介入治疗前后进行能够有效表达左心室收缩、舒张功能及左心室功能指标的变化情况，可对介入治疗的效果做出有效评价。

Abstract

Objective To investigate the effect of left ventricular echocardiography in patients with coronary heart disease.
Methods 50 patients with coronary heart disease admitted in our hospital from September 2021 to November 2022 were selected as the study objects. All the patients were treated with interventional therapy. Before and after treatment, patients were treated with echocardiography of left ventricle, and they were set as the experimental group. 50 healthy people in the same period were selected as the reference group. The indexes of EDV, ESV, SV, EF, LVEF, LVEDP, K value and T value were compared between the two groups.
Results Before treatment, LVEF, LVEDP, K value and T value in the experimental group were significantly different from those in the reference group (P<0.05). After treatment, the experimental group was significantly improved compared with those before treatment, with statistical significance (P<0.05). After treatment, there was no significant difference between the experimental group and the reference group, without statistical significance (P>0.05). The indexes of EDV, ESV, SV and EF in the experimental group before treatment were significantly different from those in the reference group (P ＜ 0.05), and the experimental group improved significantly after treatment compared with those before treatment, with statistical significance (P ＜ 0.05). The experimental group had no statistical significance after treatment compared with the reference group (P ＞ 0.05).
Conclusion   It is of great significance to take echocardiography of left ventricle in patients with coronary heart disease, especially before and after the intervention treatment, which can effectively express the changes of left ventricular systolic and diastolic functions and indexes of left ventricular function, and can effectively evaluate the effect of intervention treatment.
