Blood test for hidden troponin in heart attack and runners
This study looks at a special blood test to find 'macrotroponin' — a harmless form of a heart protein that can cause confusing results. It compares people having a heart attack with marathon runners to improve heart attack diagnosis.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are either a person who recently had a heart attack (with high troponin levels) or a marathon runner who passed a heart check-up.
- You must be 18 or older.
- If you had a heart attack, you cannot have end-stage kidney disease, known macrotroponin, cancer, or be pregnant.
- If you are a marathon runner, you cannot have coronary artery disease, structural heart disease, cancer, or be pregnant.
- Marathon runners must have no signs of heart or blood vessel problems.

This study looks at whether a simple blood test for troponin (a protein released when heart muscle is damaged) can help doctors predict how patients with acute myocarditis (heart muscle inflammation) will do over time. It may help guide follow-up care for people recovering from this condition.
This trial tests whether a highly sensitive blood test can quickly and accurately diagnose a heart attack in people arriving at the hospital with chest pain or other symptoms. If you qualify, you may receive a faster diagnosis, which could lead to quicker treatment.
This study tests whether a quick blood test done by paramedics in the ambulance can safely rule out a heart attack in patients with chest pain or similar symptoms. The goal is to help patients get faster, more accurate care before reaching the hospital.
This study compares two versions of a sensitive heart attack blood test to see how well the newer version can quickly rule out heart attacks in the emergency department. You'll have blood drawn as part of your normal care, and researchers will review your medical records.
This study tests a faster way to measure a heart-muscle protein (troponin) in the emergency room, to see if it can help doctors decide sooner whether your chest pain is from a heart attack. If you are having chest pain that started a few hours ago, you may be able to join.
This study looks at blood test “markers” soon after an acute heart attack, to better understand heart damage and whether heart failure is present. It may help doctors improve how they monitor recovery and risk in people after a heart attack.
