What this trial studies

This study aims to assess the incidence of recurrent thromboembolic venous disease and identify risk factors for recurrence in two specific groups: individuals under 50 years old and cancer patients. It focuses on the serious complications associated with deep vein thrombosis (DVT) and pulmonary embolism (PE), which can lead to significant mortality and long-term health issues. Participants will provide biological samples to aid in the research. The study is conducted at the University Hospital in Brest, France.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of thromboembolic venous disease, potentially reducing recurrence rates and associated complications.

How similar studies have gone: Other studies have shown success in understanding thromboembolic disease, but this specific cohort approach focusing on age and cancer status is relatively novel.
