Scientists investigate why some blood clot patients suffer lasting damage
NCT ID NCT06257290
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how platelets (small blood cells) might cause long-term complications like leg swelling or breathing problems after a blood clot. Researchers measured specific receptors on platelets in 44 patients to see if they were linked to these lasting issues. The goal was to better understand why some people recover fully while others do not.
