| 摘要 目的：探讨超声心动图检查对慢性肺源性心脏病患者右心功能的诊断价值。方法：选取2016年8月至2017年12月间本院收治的35例慢性肺源性心脏病患者作为实验组，并选择同期健康体检者35例作为对照组，全部受试者均给予超声心动图检查。分别比较两组右房横径（RA）、右室前后径（RV）、肺动脉平均压（MPAP）、射血分数（EF）、舒张晚期A波峰值流速与舒张早期E波峰值流速的比值（A/E）和右心室Tei指数。同时比较实验组采用常规12导联心电图检查及超声心动图检查的诊断阳性率、右心扩大阳性率和右心扩大伴心衰阳性率。结果：与对照组相比，实验组RA、RV以及MPAP均升高，组间比较差异有统计学意义（P<0.05）。与对照组相比，实验组EF明显降低，而A/E值、Tei指数明显升高，组间比较差异有统计学意义（P<0.05）。实验组超声心动图检查的诊断阳性率、右心扩大阳性率和右心扩大伴心衰阳性率均高于常规12导联心电图检查（P<0.05）。结论：应用超声心动图检查能够有效诊断慢性肺源性心脏病患者的右心功能，而且操作简单方便，诊断阳性率较高。 |

| ABSTRACT Objective: To inveterate the diagnostic value of echocardiography of right ventricular function in patients with chronic cor pulmonale. Methods: 35 patients with chronic cor pulmonale who were admitted in our hospital from August 2016 to December 2017 were enrolled as the experimental group, and 35 healthy physical examination in the same period were enrolled as the control group. All subjects were given echocardiographic examination. The right atrial transverse diameter (RA), right ventricular anteroposterior diameter (RV), pulmonary artery mean pressure (MPAP), ejection fraction (EF), late diastolic A wave peak velocity and the ratio of early diastolic E wave to peak flow velocity (A/E) and right ventricular Tei index were compared between the two groups respectively. At the same time, the positive rate of diagnosis, the positive rate of right heart enlargement and the positive rate of right heart enlargement with heart failure in the experimental group were compared with routine 12 lead electrocardiogram and echocardiography. Results: Compared with the control group, the RA, RV and MPAP in the experimental group were all higher, and there were significant differences between the groups (P<0.05). Compared with the control group, the EF in the experimental group was significantly lower, but the A/E value and the Tei index were significantly higher,and there were significant differences between the groups (P<0.05). The positive rate of diagnosis, the positive rate of right heart enlargement and the positive rate of right heart enlargement with heart failure in the experimental group were higher than those of the routine 12 lead electrocardiogram examination (P<0.05). Conclusion: Echocardiography can accurately diagnose the right ventricular function of patients with chronic cor pulmonale, moreover, the operation is simple and convenient, and the positive rate of diagnosis is higher. |
