Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a prospective, observational, multicenter cohort study to compare right ventricular dysfunction dependent and independent prognostic models for short-term serous adverse events in patients who are diagnosed with pulmonary embolism in the emergency department. Clinical endpoints are assessed at days 1-5. A thirty-day follow-up phone call is conducted to obtain further clinical endpoints and a quality of life assessment.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The objective of this study is to compare right ventricular dysfunction (RVD)dependent and independent prognostic models for short-term serious adverse events in pulmonary embolism (PE) patients. The target population is emergency department (ED) patients with confirmed acute PE within 12 hours of ED presentation. The primary outcome is a composite of death, delayed circulatory or respiratory dysfunction, hypoxia, and reperfusion intervention within five days of PE diagnosis. Secondary outcomes will be nonfatal bleeding, recurrence of venous thromboembolism, and hypoxia requiring oxygen supplementation.

The specific aims are: 1) determine the incidence of death, circulatory and respiratory deterioration, and administration of reperfusion therapy within five days of PE; 2) determine functional outcomes 30 days after PE using the Pulmonary Embolism Quality of Life Questionnaire; 3) evaluate the sensitivity, specificity, and positive and negative likelihood ratios of each RVD assessment tool for clinical deterioration within five days of PE; and 4) derive a prediction model for clinical deterioration within five days of PE diagnosis.

Patients with confirmed PE will be assessed for hemodynamic stability at presentation, and then will be assessed for RVD. Normotensive PE patients without RVD will be assessed by a clinically derived model (sPESI or HESTIA) to determine if they are low risk or intermediate-low risk. The investigators will then determine incidence of the clinical endpoints during the subsequent 5 days, as well as 30 days later. The 30-day follow-up will also include administration of the validated Pulmonary Embolism Quality of Life questionnaire (PEmbQoL).

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Men and women, 18 years or older, with image confirmed acute pulmonary embolism diagnosed within 12 hours of ED presentation

Exclusion Criteria

* Patients who decline any participation in the study
* Patients 17 years old and younger at the time of screening
* Radiologist's over read that determines that filling defects identified as acute emboli are instead either chronic, resolving, or unchanged after comparison to previous CT, if available
* If empiric anticoagulation or escalated intervention were initiated more than 12 hours before presentation to the recruiting ED
* Identification of either segmental or subsegmental intraluminal filling defects on CT that are considered to be clinically incidental and unrelated to primary diagnostic workup or ED presentation.
