Predicting Atrial Fibrillation with a Genetic Risk Score

Official title: Development of an Atrial Fibrillation Prediction Model Using Polygenic Risk Score: A Prospective Cohort Study

Run by Seoul St. Mary's Hospital · NCT07641582 · Data updated 2026-11-12

Researchers test whether a polygenic risk score can help flag people likely to have undiagnosed atrial fibrillation, alongside at-home and clinic heart monitoring.

Is this trial a fit for you?

Likely a good fit

Adults aged 60 or older with AF risk factors or symptoms suggestive of paroxysmal AF, who have not been previously diagnosed with AF.

Probably not a fit

Individuals younger than 60 without risk factors or those with existing AF diagnosis may derive less benefit from this approach.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study enrolls adults at risk for AF and uses a genetic risk score derived from SNP data to predict AF. Participants wear a 7-day continuous ECG patch, provide a blood sample for SNP genotyping, and use a handheld six-lead ECG at home for up to a year, with five in-clinic visits. The goal is to see if combining genetic risk with medical history improves AF prediction over using history alone. The study will develop and validate a scoring system to identify individuals at higher AF risk to inform targeted screening. Overall, the trial integrates genetic testing with wearable and handheld ECG monitoring to enhance early AF detection.

Why it matters

Potential benefit: If successful, the approach could enable earlier and more targeted AF screening, potentially reducing stroke risk through timely treatment.

How similar studies have gone: Prior research suggests polygenic risk scores can stratify AF risk, but integrating PRS with practical screening tools in a prospective design is still being evaluated.
