Full textVenous thromboembolism (VTE) is the third leading cause of cardiovascular death. Pulmonary embolism (PE) is the most severe form of venous thrombosis. Patients with unprovoked PE are at high risk of residual pulmonary vascular obstruction (RPVO). Failure to resolve the thrombus increases the risk of thromboembolie recurrence. The aim of this work was to assess the impact of three mechanisms potentially involved in thrombus persistence: inflammation, endothelialdysfunction and fibrinolysis in patients with unprovoked PE.A preliminary study shows that fibrinolysis defect and endothelial dysfunction are involved in perfusion sequelae in a population of patients presenting with a first episode of unprovoked PE.A semi-automated Clôt Lysis Assay (CLA) was set up to assess coagulation and fibrinolysis and plasma levels of TGFβ1 are quantified. TGFβ1 plasma levels measured one month after anticoagulant discontinuation are associated with RPVO, while fibrinolysis parameters are not. Clôt formation parameters measured by CLA are associated with VTE recurrence. These results provide a better understanding of the pathophysiology of RVPO and VTE recurrence to optimise the treatment of unprovoked PE

Full textPulmonary vascular sequels after pulmonary embolism: prognosis, prediction and physiopathologyAbstract: Post Pulmonary Embolism (PE) syndrome is not rare after PE: one third of the patients presents residual pulmonary vascular obstruction (RPVO) traducing sequels associated with increased dyspnea and impaired exercise capacity. Some of these patients will suffer PE recurrence or, more rarely, chronic thromboembolic pulmonary hypertension, whose one the diagnosis criteria is persistent perfusion defect. Prognosis value and mechanisms underlying vascular sequels are still unclear. The present work shows that RPVO > 10% after a first PE is associated with an increased risk for venous thromboembolism recurrence (odds ratio 1.9). Secondly, fibrinogen properties were investigated in PE patients. Patients with RPVO >10% presented more monosialiated Bβchain form. Prediction models for RPVO that include fibrinogen analysis were more accurate than those without fibrinogen data; This results highlights the key role of fibrin in the pathophysiology of chronic venous thromboembolism. Interestingly, the present work shows that patient who will present RPVO had an impaired endothelial cells mobilization. Compared to patients without RPVO, patients with RPVO had lower circulating endothelial cells at the acute phase of PE. This endothelial dysfunction is probably triggered by endothelial progenitors that expressed the very low density lipoprotein receptor (VLDLr), implicated in the inhibition of angiogenesis and able to bind the β15-42 N terminal sequence of the fibrin Bβ chain
