About this trial

The goal of this clinical trial is to learn whether a genetic risk score can help identify undiagnosed atrial fibrillation (AF) in adults who may have it. AF is an irregular heartbeat that raises the risk of stroke if not treated early.

The main questions it aims to answer are:

Can a polygenic risk score (PRS) - a score based on a person's genes - identify who is more likely to have AF? Does combining PRS with a person's medical history predict AF better than using medical history alone?

Participants will:

Wear a continuous ECG patch for 7 days to record heart rhythm Give a blood sample for genetic testing to calculate their PRS Use a six-lead handheld ECG device (HATIV® P30, VUNO Inc., Seoul, Republic of Korea) to check their own heart rhythm at home once or twice a week for 1 year Visit the clinic 5 times over 1 year

Researchers will use the genetic and clinical information collected to build a scoring system that predicts who is at risk for AF.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Patients with symptoms suggestive of paroxysmal atrial fibrillation, such as intermittent palpitations or chest discomfort

Asymptomatic patients aged 60 or older with at least one of the following risk factors for atrial fibrillation: hypertension, diabetes, coronary artery disease, valvular heart disease, cardiomyopathy, sleep apnea, hyperthyroidism, obesity (BMI greater than 30), or chronic alcohol dependence (drinking more than 3 times per week)

Disqualifiers

Age under 20 years or over 80 years

Moderate or severe cognitive impairment

Previously diagnosed with atrial fibrillation prior to study enrollment

Does not consent to participate in the study

Trial design

Design model

Single group

Treatments tested in this trial

  • 7-day continuous ECG patch monitor

    Device

    Continuous ECG patch worn for 7 days at enrollment to detect atrial fibrillation and other arrhythmias.

  • Six-lead handheld electrocardiogram device

    Device

    Six-lead ECG device used for self-monitoring at least once or twice weekly and upon symptoms for 1 year.

  • SNP array genotyping

    Genetic

    DNA extracted from a 5cc blood sample is used to perform SNP array genotyping. The resulting data are used to calculate a polygenic risk score (PRS) for atrial fibrillation based on previously published genome-wide association study results.
