Prognosis Wars: A New HOPPE to Identify Low-Risk Pulmonary Embolism

A subset of patients with acute pulmonary embolism (PE), are at low risk for short-term complications and can be discharged safely from the hospital or emergency department (ED). To determine how to identify such patients, investigators retrospectively studied a cohort of 400 consecutive patients with radiographically confirmed pulmonary embolism at a single tertiary care center in India.

Multivariate analysis identified five independent predictors of 30-day mortality:

• Heart rate

• PaO₂ (arterial partial pressure of oxygen)

• Systolic blood pressure

• Diastolic blood pressure

• Electrocardiographic score

The HOPPE score stratified patients into low-risk (0% risk for PE-related 30-day mortality), intermediate-risk (8%), and high-risk (19%) groups, each com…
