One blood test to rule out heart attacks?
NCT ID NCT01334645
First seen Aug 06, 2026 · Last updated Aug 07, 2026 · Updated 1 time
Summary
This study is testing whether measuring a protein called copeptin in the blood, alongside the standard troponin test, can help doctors quickly rule out a heart attack in people arriving at the emergency room with chest pain. Participants with chest pain that started within the last 12 hours will have blood samples taken over several hours to measure copeptin, troponin, and other markers. The goal is to see if a normal copeptin and troponin result can safely exclude a heart attack without the need for prolonged monitoring and repeated blood tests.
