心脏彩超对AECOPD并发肺栓塞的评估价值

The Assessed Value of Cardiac Color Ultrasound on AECOPD Complicated with Pulmonary Embolism

本文探讨心脏彩超评估慢性阻塞性肺疾病急性加重(AECOPD)合并急性肺栓塞的价值。选取AECOPD合并急性肺栓塞患者65例作为观察组,同时选取单纯AECOPD患者130例作为对照组。结果显示,观察组肺动脉内径(PA)、右室内径(RV)、右房内径(RA)和舒张晚期峰值速度(Am)明显高于对照组(P<0.05),而肺动脉瓣口流速(PV)、舒张早期峰值速度(Em)明显低于对照组(P<0.05);观察组预后不良患者PA、RV、RA明显高于预后良好患者(P<0.05),而PV明显低于预后良好患者(P<0.05);PA、RV、RA和PV预测预后不良的ROC曲线下面积较优。心血管参数与AECOPD并发肺栓塞患者病情程度、预后有关,在预测预后方面有一定价值。

The purpose of this study was to evaluate the value of color Doppler echocardiography in acute exacerbation of chronic obstructive pulmonary disease(AECOPD) complicated with acute pulmonary embolism. There were 65 cases AECOPD patients with acute pulmonary embolism were selected as the observation group, and 130 patients with AECOPD were selected as the control group. The results showed that the pulmonary artery diameter(PA), right ventricular diameter(RV), right atrial diameter(RA) and late diastolic peak velocity(AM) of the observation group were significantly higher than that in the control group(P<0. 05), while the pulmonary valve velocity(PV) and early diastolic peak velocity(Em) were significantly lower than that of the control group(P<0.05).In the observation group, the PA, RV and RA of patients with poor prognosis were significantly higher than those of patients with good prognosis(P<0.05), and the PV was significantly lower than the patients with good prognosis(P<0.05). The areas under the ROC curve for PA, RV, RA and PV to predict poor prognosis were good. Cardiovascular parameters are related to the severity and prognosis of patients with AECOPD complicated with pulmonary embolism, and have certain value in predicting the prognosis.
