Could damaged lung vessels explain long COVID breathlessness?
NCT ID NCT05374577
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study looks at whether problems with blood vessels in the lungs cause ongoing shortness of breath in people who had COVID-19. Researchers will use heart and lung tests, including exercise and imaging, in 200 adults. The goal is to better understand why some people feel breathless long after their infection clears.
