An Observational Study About Adverse Outcomes in Acute Pulmonary Embolism Patients

This multi-center retrospective study collected clinical, laboratory, and CT pulmonary angiography parameters with acute pulmonary embolism patients from admission to predict adverse outcomes within 30 days after admission into hospital. Eligible patients were collected to develop and evaluate a simple predictive model for predicting the adverse outcomes. The discriminatory power was evaluated by comparing the nomogram to the established risk stratification systems. The consistency of the nomogram was evaluated using the validation cohort.
