BurdEn of NEw Onset Atrial FIbrillation in patienTs With Acute Myocardial Infarction: the BENEFIT-AMI Multicenter Prospective Registry

Observational Shanghai 10th People's Hospital · NCT04528511

This study is trying to see how new-onset atrial fibrillation affects heart attack patients and if it can help guide their treatment after they leave the hospital.

What this trial studies

This study aims to validate the prognostic significance of new-onset atrial fibrillation (NOAF) in patients who have experienced an acute myocardial infarction (AMI). It will establish a multicenter, prospective registry involving patients from nine tertiary medical centers in China. The study will collect comprehensive data on patient demographics, cardiovascular risk factors, and NOAF characteristics, including its burden and patterns. Patients will be monitored for at least two years post-discharge to assess cardiovascular outcomes and the potential role of NOAF burden in guiding anticoagulation therapy.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 who have experienced an acute myocardial infarction and developed new-onset atrial fibrillation during hospitalization.

Not a fit: Patients with a history of pre-existing atrial fibrillation or those undergoing emergency coronary artery bypass surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve risk stratification and treatment strategies for patients with new-onset atrial fibrillation following a heart attack.

How similar studies have performed: Previous studies have indicated a poor prognosis associated with a greater burden of NOAF in similar patient populations, suggesting that this approach may yield valuable insights.
