目的通过超声心动图技术的联合应用探讨肺栓塞高危组右心功能的超声心动图分型、分析,评估治疗的效果。方法选取同期住院的肺栓塞高危组患者76例,均接受尿激酶溶栓治疗。治疗前和治疗2周后均观察超声心动图检查指标,包括实时三维超声心动图(RT-3DE)技术测量右心室舒张末期容积(RVEDV)及射血分数(RVEF);多普勒超声测量三尖瓣反流压力阶差(TRPG)及三尖瓣口前向血流舒张早期峰值速度(Em);组织多普勒成像技术(TDI)测量三尖瓣环心肌运动舒张早期峰值速度(E’m),计算Em/E’m,观察比较指标变化。结果治疗后超声心动图显示,患者的RVEDV、TRPG、Em/E’m较治疗前显著减小,RVEF较治疗前显著提高,差异有统计学意义(P<0.05)。结论通过超声心动图技术的联合应用对肺栓塞高危组右心功能进行分型、评估,可帮助临床医生了解其预后效果。
Objective To investigate the echocardiographic classification and analysis of right heart function in high-risk pulmonary embolism patients through the combined application of echocardiography and evaluate the therapeutic effect. Methods Totally 76 high-risk patients in hospitalized patients with pulmonary embolism were enrolled in this study. Echocardiography was performed before treatment and 2 weeks after treatment, including right ventricular end-diastolic volume (RVEDV) and ejection fraction (RVEF) by real-time three-dimensional echocardiography (TRPG), and peak early diastolic velocity (Em) of tricuspid preeclampsia were measured. The early diastolic peak velocity (E’m) of tricuspid annular myocardium was measured by tissue Doppler imaging (TDI) , Calculate Em / E’m, observed and compared changes in indicators. Results Echocardiography showed that RVEDV, TRPG and Em / E’m in patients were significantly lower than those before treatment, and RVEF was significantly higher than that before treatment (P <0.05). Conclusion The combination of echocardiography and high risk group of pulmonary embolism right heart function classification, evaluation, can help clinicians understand the prognosis.
