The Application of Biomarkers in the Care of Patients With Atrial Fibrillation

May 3, 2026 updated by: National Taiwan University Hospital

From 2020 to 2023, we established a longitudinal AF patient cohort with comprehensive clinical data collection. In our previous work, we utilized the Milliplex platform to screen 52 circulating biomarkers and identified several candidates potentially associated with AF burden. Building on these findings, the present study aims to further validate these biomarkers in a larger subset of patients (n=266) who completed paired pre- and post-intervention sampling. Targeted biomarkers may include NT-proBNP, IL-6, hs-CRP, Adipsin, GDF-15, sST-2, FABP3, and IGF-BP3.

Our goal is to identify markers associated with AF burden, assess their predictive performance and subgroup consistency, and further elucidate the underlying pathophysiological mechanisms.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

With an aging population and advances in medical care, the prevalence of atrial fibrillation (AF) continues to rise. Although the introduction of novel oral anticoagulants has reduced the risk of stroke, AF can still lead to myocardial ischemia, fibrosis, and ultimately heart failure and valvular dysfunction. Given its often paroxysmal nature, the diagnosis and assessment of AF burden remain challenging and frequently rely on prolonged electrocardiographic monitoring.

Identifying accessible and reliable blood-based biomarkers could provide a cost-effective alternative to time-consuming and expensive wearable or implantable monitoring devices, offering significant clinical value.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

This study is a follow-up to the prospective generational study (AFTTER: Atrial Fibrillation Trial To Eliminate Risk-factors; NCT05718336) that enrolled patients from 2020 to 2023. After consenting to participate in this study, patients underwent a series of questionnaires, blood tests, and special examinations (see the figure below). The caregiver (the arrhythmia treatment team at National Taiwan University Hospital) formulated a treatment plan based on the examination results. After approximately two years (at least one year) of treatment, a post-test was conducted to conclude the study (a total of 343 patients were enrolled in this study, of which 266 participants completed the pre- and post-treatment tests and blood tests).

Description

Inclusion Criteria:

-Who have signed up for the Protocol No. 202003090RINA(National Taiwan University Hospital Atrial Fibrillation Integrated Care Pilot Program)

Exclusion Criteria:

-Subjects without complete pre- and post-treatment testing

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Novel biomarkers
Time Frame: 1YEARS
Whether novel biomarkers are associated with atrial fibrillation burden and could serve as tools to assist clinicians in diagnosing and treating patients, including tracking treatment effectiveness or the timeline for progression to heart failure;

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 1, 2026

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
