NCT ID NCT07498868
First seen Apr 06, 2026 · Last updated Jun 20, 2026 · Updated 17 times
Summary
This study will test a simple finger-prick blood test that gives results in 12 minutes to screen for heart failure in people with leg swelling (lymphoedema). Heart failure often goes undetected because leg swelling is mistaken for lymphoedema. The study will involve 618 adults in Wales and compare the quick test to standard lab tests to see if it helps diagnose heart failure faster and more efficiently.
