Blood test may spot hidden heart danger in lung clots
NCT ID NCT07616557
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a routine blood test (RDW) can help doctors quickly identify how well the heart and lungs are working together in people with a sudden lung clot (pulmonary embolism). Researchers will measure RDW and compare it to an ultrasound measure of heart-lung coupling in 190 adults. The goal is to see if RDW can serve as an early warning sign of heart strain, without any direct treatment being tested.
