Understanding heart injury in patients with rapid atrial fibrillation

Mechanisms of Myocardial Injury and Ischemia in Patients With Rapid Atrial Fibrillation

Observational University of Edinburgh · NCT06951100

This study is trying to see if people with rapid atrial fibrillation and heart injury are more likely to have blocked arteries compared to those without heart injury, using blood tests and heart imaging.

What this trial studies

This observational study aims to investigate the relationship between rapid atrial fibrillation (AF) and myocardial injury, focusing on the role of troponin levels and coronary imaging. It seeks to determine if patients with rapid AF and heart damage are more likely to have obstructive coronary artery disease compared to those without heart damage. Additionally, the study will assess whether these patients show signs of myocardial ischemia and infarction through various heart imaging techniques. Participants will undergo blood tests and advanced imaging, including electrocardiograms, echocardiograms, CT scans, and cardiac MRIs.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and over presenting with symptoms of rapid atrial fibrillation and a ventricular rate greater than 100 bpm.

Not a fit: Patients with a history of myocardial infarction, coronary revascularization, or significant renal failure may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic strategies for patients with rapid atrial fibrillation and associated heart injuries.

How similar studies have performed: Other studies have explored similar relationships between atrial fibrillation and myocardial injury, suggesting potential for meaningful insights, though this specific approach may be novel.
