Prevalence and Risk Factors of Chronic Thrombo-embolic Disease After a Pulmonary Embolism Event (PACTE)

30 de setembro de 2021 atualizado por: Centre Hospitalier Universitaire de Nice

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.

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

Number of patient with a persistence of a DVT and the persistence of deep vein thrombosis (The persistence of DVT being defined by the presence of a venous thrombus of the same location as that of the initial episode)

Measurement of the level of CTED according to the persistence of deep vein thrombosis beyond diagnosis. 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.
3 to 6 months after pulmonary embolism
Associated risk factors (new episode of PE or DVT ) for CTED occurrence

Agreement between the clinical presumption of CTED by an experienced physician (questioning and evaluation of dyspnea) compared to the diagnosis of CTED by lung scintigraphy. 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.
