研究90例血液动力学稳定的肺栓塞(PE)患者右心室室壁活动异常和肺扫描灌注缺损之间的关系。 方法 101例血液动力学稳定的PE患者,随机分组接受TY-PA加肝素或单独肝素治疗。在基础状态下,治疗开始后3及24小时作经胸超声心动检查。在基础状态下和治疗24小时后作肺灌注扫描。随访14天,有复发性PE征象者重复肺扫描。分析超声心动图时定性地将右室收缩功能分为正常或异 To investigate the relationship between abnormal right ventricular wall motion and lung perfusion defect in 90 patients with hemodynamically stable pulmonary embolism (PE). Methods A total of 101 patients with hemodynamically stable PE were randomized to receive either TY-PA plus heparin or heparin alone. Under basal conditions, transthoracic echocardiography was performed 3 and 24 hours after the start of treatment. Lung perfusion scans were performed at baseline and 24 hours after treatment. After 14 days of follow-up, repeat lung scan was performed on patients with recurrent PE signs. Analysis of echocardiographic qualitatively right ventricular systolic function is divided into normal or different
