Prospective Validation of an Acute Pulmonary Embolism Severity and Prognosis Prediction Model

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.

Inclusion Criteria:age ≥ 18 yearsInpatients with acute PTE diagnosed by imaging (CTPA, enhanced CT, V/Q imaging suggesting a high probability of PE, pulmonary angiography, MRPA) containing any of the following conditions.primary acute PTE combined with or without DVTrecurrent acute PTE with a history of previous PTE or DVTsigned informed consent formExclusion Criteria:blinded to any diagnostic or therapeutic test (VTE or other conditions)unable to complete follow-up (due to cognitive or behavioral limitations, etc.)
