研究目的:

探索基于抗 Xa 因子活性指导肺栓塞院内抗凝,对 APE 转归的影响。通过单中心随机对照临床干预性研究,入选 APE 患者 372 例,随机分为据抗Ⅹa 因子活性组及据体质量、肾功能、APTT 组,对比两组 PPES 发生率,探索抗Ⅹa 因子活性对 APE 转归的影响,并通过多因素 logistic 回归分析建模初步探索抗Ⅹa 因子活性指导下抗凝出血事件的相关因素。  

Objectives of Study:

To explore the impact of in-hospital anticoagulation monitored by Anti-factor Xa level on the outcomes of acute pulmonary embolism (APE). A single-center randomized controlled clinical interventional study will be conducted, enrolling 372 APE patients who will be randomly divided into two groups: the anti-factor Xa level monitored group and the group monitored by body weight, renal function, and activated partial thromboplastin time (APTT). The incidence of post-pulmonary embolism syndrome (PPES) between the two groups will be compared to investigate the effect of anti-factor Xa level on APE outcomes. Additionally, a multivariate logistic regression analysis will be used to establish a model for preliminarily exploring the related factors of anticoagulant bleeding events under the monitoring of anti-factor Xa level.
