Prevalence and Risk Factors of Chronic Thrombo-embolic Disease After a Pulmonary Embolism Event (PACTE)
Prevalence and Risk Factors of Chronic Thrombo-embolic Disease After a Pulmonary Embolism Event The PACTE Registry
Venous thromboembolic disease (VTE) is a common clinical entity whose two manifestations are deep vein thrombosis (DVT) and pulmonary embolism (PE). After an acute PE, almost half of the patients complain residual dyspnea, despite well-conducted curative anticoagulation. Some will present persistent defects on lung scan-scintigraphy, without pulmonary hypertension. This condition defines Chronic-Thrombo-Embolic Disease(CTED). The prevalence of CTED after PE is poorly known as are its risk factors.
The primary objective is to determine the prevalence of CTED at 3 or 6 months, depending on the provoked or unprovoked character, after a PE.
The secondary objectives are:
- To determine the potential risk factors for the occurrence of CTED.
- To look for an association between the persistence of DVT and the occurrence of CTED.
- To look for an association between the diagnosis of CTED and PE recurrence during the 12-month follow-up.
- To determine the diagnostic performance of the clinician alone compared to the lung scintigraphy (gold standard) for the diagnosis of CTED.
- To compare the impact on the quality of life (QoL) with or without CTED.
- To determine the correlation between impaired QoL and the degree of residual obstruction on lung scintigraphy.

Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
pulmonary embolism
Patients with a recent pulmonary embolism event will be followed for 6 months and will benefit of routine tests (Lung scintigraphy, venous echo doppler, d- dimers measurement) in order to determine chronic thrombo-embolic disease prevalence and its risk factors.

NO INTERVENTION

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Chronic thrombo-embolic disease (CTED) prevalence
Time Frame: 3 to 6 months after pulmonary embolism
|
CTED is determined by lung ventilation-perfusion scintigraphy witch detect a persistant obstruction more than 10% of the pulmonary arteries perfusion (defined by amputation of at least two pulmonary segments on V/ Q lung scan).
|
3 to 6 months after pulmonary embolism
|

The persistence of a DVT is defined by the presence at 3 or 6 months of a venous thrombus of the same location as the initial episode, among the patients who presented with a PE associated with a DVT. |

The clinical presumption by the clinician (presence or not of an CTED) is based on the questioning, the clinical examination and the realization of an echocardiography, if necessary, in order to rule out pulmonary hypertension.
