Shock score for prediction of clinical outcomes among stable patients with acute symptomatic pulmonary embolism.

Background: The Composite Pulmonary Embolism Shock (CPES) score has been developed to identify normotensive patients with acute pulmonary embolism (PE) and a low cardiac index (referred to as normotensive shock). We aimed to externally assess the validity of this model for predicting a complicated course among hemodynamically stable patients with acute PE.

Methods: Using prospectively collected data from the PROgnosTic valuE of Computed Tomography scan (PROTECT) study, we calculated the CPES score for each patient and the proportion of patients with a score > 3.

Usefulness of the National Early Warning Score for Risk Stratification of Stable Patients With Acute Symptomatic Pulmonary Embolism.

Objectives: The aim of this study was to assess the performance of the National Early Warning Score 2 (NEWS2) in predicting a short-term complicated outcome in stable patients with acute symptomatic pulmonary embolism (PE). We also studied the ability of the NEWS2 score compared with the simplified Pulmonary Embolism Severity Index (sPESI) for identifying low-risk patients with acute PE.

Methods: We performed a retrospective analysis of a prospective cohort composed of 848 patients with acute PE.
