The purpose of this study is to prospectively validate the first PUMCH model for acute PE severity and prognosis prediction based on multi-center data constructed in the pre-project period based on national population data, and to optimize the PUMCH model based on artificial intelligence clustering algorithm.
Patients with pulmonary embolism and aged 18 years or older were enrolled in this study.Patient demographic characteristics(age, sex, department, diagnosis), basic vital signs, symptoms at their admissions (hemoptysis, dyspnea, chest pain, syncope, laboratory examinations (blood lab routines, blood gas, liver and kidney function, myocardial marker), and imaging examinations (vascular ultrasonography, computed tomographic angiography, echocardiography, chest CT,CTPA, pulmonary perfusion imaging, pulmonary angiography, PET/CT) were prospectively collected.
