Timing matters: study probes speed of blood thinner in lung clot patients
NCT ID NCT06912009
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at 100 adults hospitalized in the ICU for a serious pulmonary embolism (a blood clot in the lung). Researchers want to know how long it takes for the blood thinner (unfractionated heparin) to reach a level that prevents more clots. They will also check if faster blood thinning is linked to lower death rates, fewer repeat clots, or more bleeding. The goal is to improve how doctors start and monitor this treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- unfractionated heparin (UFH)
- What this could lead to
- If successful, this could help doctors understand the best way to start blood thinners quickly in ICU patients with pulmonary embolism, potentially improving survival and reducing complications.
- What could go wrong
- This is a small, single-center, retrospective study, so results may not apply to all hospitals or patients. It only looks at past data, so it cannot prove cause and effect.

Inclusion Criteria: * Adult patient (≥18 years old) * Hospitalized in the intensive care unit of Hautepierre Hospital (Strasbourg University Hospitals UF 6250) between January 1, 2014, and December 31, 2023 * With a diagnosis of pulmonary embolism confirmed by a thoracic CT angiogram, a thoracoabdominopelvic CT scan, or a lung scan * Having received anticoagulation with curative-dose unfractionated heparin Exclusion Criteria: * Subjects who have expressed objection to the reuse of their data for scientific research purposes. - Patients diagnosed with pulmonary embolism prior to admission to the intensive care unit and for whom we cannot precisely determine the start date of anticoagulation (precision estimated to the nearest hour). * Pulmonary embolism not confirmed by contrast imaging (CT angiography) * Patients who have not received curative anticoagulation (contraindication) * Patients already receiving curative anticoagulation with UFH at the time of diagnosis * Patients with low-risk pulmonary embolism defined by an sPESI score of 0 * Subject under court protection, guardianship, or curatorship
