Chronic Emboilism Clinical Trial
Official title:
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.
