500 stroke patients enrolled to uncover hidden clues in blood and brain scans
NCT ID NCT05263804
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is following 500 adults who had an ischemic stroke (a clot blocking blood flow in the brain). Researchers are collecting blood samples, brain scans, and health data to find new markers that can predict how well someone will recover and whether they will develop heart problems after a stroke. The goal is to better understand stroke recovery and identify new targets for future treatments.
