目的:通过超声心动图测量肺动脉压力并评估其在急性肺血栓栓塞症危险分层中的意义。方法:将58例超声心动图资料完整的急性肺血栓栓塞症患者分为肺动脉高压组和对照组,分别对其危险因素、临床特征、治疗方法及其预后进行分析。结果:肺动脉高压组发病至就诊时间显著短于对照组;晕厥、咯血的发生率显著高于对照组;肺动脉高压组D-二聚体水平显著高于对照组,而氧分压及二氧化碳分压指标显著低于对照组;肺动脉高压组患者S1Q3T3及右束支传导阻滞发生率显著高于对照组,死亡及发生临床不良事件的比例显著高于对照组。结论:肺动脉高压可作为评价急性肺血栓栓塞症严重性及预后不良的指标。
PURPOSE: To measure pulmonary artery pressure by echocardiography and evaluate its significance in risk stratification of acute pulmonary thromboembolism. Methods: 58 cases of acute pulmonary embolism with complete echocardiography were divided into pulmonary hypertension group and control group, and their risk factors, clinical features, treatment methods and prognosis were analyzed respectively. Results: The incidence of pulmonary hypertension was significantly shorter than that of the control group. The incidence of syncope and hemoptysis was significantly higher than that of the control group. The D-dimer level of pulmonary hypertension group was significantly higher than that of the control group. However, the partial pressure of oxygen and carbon dioxide The indexes of S1Q3T3 and right bundle branch block were significantly higher in patients with pulmonary hypertension than those in control group. The proportions of death and clinical adverse events were significantly higher than those in control group. Conclusion: Pulmonary hypertension can be used as an index to evaluate the severity of acute pulmonary embolism and poor prognosis.
