Registry of the Evolution of Diagnosed and/or Hospitalized Patients for Pulmonary Embolism During the Covid-19 Pandemic (COVID-EP)

Registry of the Evolution of Diagnosed and/or Hospitalized Patients for Pulmonary Embolism During the Covid-19 Pandemic: Retrospective and Prospective Multicentric Study.

The purpose of the study COVID-EP is to classify all the complications occurring after the diagnosis of pulmonary embolism in patients tested initially COVID-19 positive and negative by RT-PCR (on nasopharyngeal sample) during the peak of the pandemic in France (April 2020). The patients will be followed for 1 year in order to provide clinical and paraclinical data not yet published in the literature. In order to secondarily confirm the COVID-19 status of initially negative COVID-19 patients (by RT-PCR), a serology test will be performed. The collected complications will then be compared between each of the 3 following groups: [PCR-COVID 19-Neg & Sero-COVID 19-Neg] versus [PCR-COVID 19-Neg & Sero-COVID 19-Pos] versus [PCR-COVID 19-Pos].

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
[PCR-COVID 19-Pos] group; Having a microbiological diagnosis confirming COVID-19 infection (ie positive RT-PCR on nasopharyngeal swab) and/or clinical/CT signs
[PCR-COVID 19-Neg] group; Having a microbiological diagnosis confirming the absence of COVID-19 infection (ie negative RT-PCR on nasopharyngeal swab) and absence of clinical /CT signs	Diagnostic test: Serology test for COVID-19; In order to secondarily confirm the COVID-19 status of initially negative COVID-19 patients (by RT-PCR), a serology test will be performed in two parts: ELISA test; Rapid Diagnostic tests (only if ELISA test is positive)
[PCR-COVID 19-Neg & Sero-COVID 19-Pos] group; Having a microbiological diagnosis confirming the absence of COVID-19 infection (ie negative RT-PCR on nasopharyngeal swab) and absence of clinical /CT signs; Having been tested positive in a serological test for COVID-19 at M3
[PCR-COVID 19-Neg & Sero-COVID 19-Neg] group; Having a microbiological diagnosis confirming the absence of COVID-19 infection (ie negative RT-PCR on nasopharyngeal swab) and absence of clinical /CT signs; Having been tested negative in a serological test for COVID-19 at M3

PE complications : Chronic interstitial pathology, or; Recurrence of PE, or; Pulmonary hypertension, or; Death.	12 months after PE diagnosis
% of patients in each group presenting the occurrence of each of the following events at each follow-up (3 months, 6 months and 12 months after PE diagnosis).	PE complications : Chronic interstitial pathology, or; Recurrence of PE, or; Pulmonary hypertension, or; Death.	3, 6 and 12 months after PE diagnosis
