Acute Pulmonary Embolism
Conditions
Brief summary
In response to the high mortality rate of patients with acute pulmonary embolism (APE) and the fact that only a small proportion of deceased patients can receive correct diagnosis, this study will use a sensitive, non-invasive, and feasible new thrombus molecular marker (TAT/PIC/TM/t-PAIC) to detect and evaluate the activation of the coagulation and fibrinolysis systems and endothelial system damage in patients, in order to monitor the early diagnosis and treatment of APE, reduce mortality, and improve patient quality of life. Therefore, this study intends to include 200 newly diagnosed APE patients to evaluate the sensitivity and specificity of the single and combined application of novel thrombus molecular markers for APE diagnosis; Detect the biomarker results of patients at different time points before and after treatment, and evaluate their value in APE treatment monitoring; Track and follow up on patients after discharge to explore the prognostic value of biomarkers for APE.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
