Cardiovascular and Venous Thromboembolism Disease in Patients with Von Willebrand Disease in the French West

• Status: Recruiting
• Phase: —
• Study type: Observational
• Enrollment: 100 (estimated)
• Sponsor: University Hospital, Brest · Academic / Other
• Sex: All
• Age: 18 Years
• Healthy volunteers: Not accepted

Summary

Due to increasing of life expectancy, patients with von Willebrand disease are exposed to age-related pathologies such as cancer or cardiovascular diseases. Management of thrombotic events is challenging given the inherent bleeding risk in von Willebrand disease. Few data are currently available in the literature. The aim of the study is to describe the frequency and nature of arterial and venous thromboembolic events and atrial fibrillation in patients with von Willebrand disease in the West of France. The investigators will perform a retrospective multicenter study conducted in the von Willebrand population of the French West. Von Willebrand adult patients followed in one of the French West medical centers participating in the study, who presented deep vein thrombosis, pulmonary embolism, ischemic stroke, transient ischemic attack, acute coronary syndrome, acute limb ischemia, atrial fibrillation, arteriopathy of the lower limbs, angina will be eligible.

Detailed description

Von Willebrand disease is the most common hereditary bleeding disorder. Due to the development of therapies, life expectancy and life quality are increasing in affected patients. However, certain treatments and/or certain comorbidities associated with venous and arterial thrombotic risks may be present in these patients. In the general population, venous thromboembolic disease, arterial thrombosis and atrial fibrillation are frequent. Their management requires the use of antiaggregants and anticoagulant molecules, themselves associated with a bleeding risk. Few data are currently available in the literature concerning the occurrence of venous and arterial thromboembolic events in patients with von Willebrand disease and their management, in the face of a hemorrhagic risk inherent to their pathology and its increase by anti-aggregant treatments and anticoagulants. The aim of the study is to describe the frequency and nature of arterial and venous thromboembolic events and atrial fibrillation in patients with von Willebrand disease in the West of France. The investigators will perform a retrospective multicenter study on data conducted in the French West. The study population is composed of patients with von Willebrand disease followed in a reference center in the French West, have consented to be included in the BERHLINGO database (Base d'Etude et de Recherche pour Les INvestigateurs en Hémostase du Grand-Ouest), and who presented deep vein thrombosis, pulmonary embolism, ischemic stroke, transient ischemic attack, acute coronary syndrome, acute limb ischemia, atrial fibrillation, arteriopathy of the lower limbs, angina. Data about von Willebrand disease, risk factors, event, treatment such as antiaggregants and anticoagulants and complications such as hemorrhage or recurrence, will be collected.
