Can we predict who dies from blood clots? a 100,000-Patient study searches for clues
NCT ID NCT07767279
First seen Aug 17, 2026 · Last updated Aug 18, 2026 · Updated 1 time
Summary
This study looks back at the medical records of over 100,000 hospitalized patients to identify which health conditions and factors are linked to a higher risk of death in people with venous thromboembolism (VTE) — blood clots in the veins, including deep vein thrombosis and pulmonary embolism. Researchers will compare patients who survived with those who died to spot high-risk factors such as respiratory failure, sepsis, and hemorrhage. The goal is to better understand what makes some VTE patients more vulnerable, which could help guide future care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help doctors identify which VTE patients are at highest risk of dying, potentially leading to more targeted monitoring and treatment.
- What could go wrong
- Because this is a retrospective observational study, it can only show associations, not cause and effect. The findings may not apply to other hospitals or patient groups.
