Atrial Fibrillation Screening: Burden or Benefit for Patients and the Healthcare System

Area of Science:

• Cardiology
• Digital Health
• Public Health

Background:

• Atrial fibrillation (AF) is a common arrhythmia significantly increasing stroke risk.
• Early detection and anticoagulation are key to reducing stroke incidence.
• Population-level screening is gaining interest due to advancements in digital health.

Purpose of the Study:

• To review large-scale trials and digital health studies on AF screening.
• To synthesize the benefits and limitations of population-level AF screening.
• To explore emerging strategies for improving AF screening efficacy and implementation.

Main Methods:

• Systematic review of large-scale trials and digital health studies.
• Analysis of wearable device-based AF detection methods.
• Evaluation of AI-guided risk stratification and digital care pathways.

Main Results:

• Screening enables earlier diagnosis of silent AF, facilitating timely treatment and potential stroke reduction.
• Challenges include false positives, inconclusive results, patient anxiety, and healthcare system strain.
• AI and digital pathways show promise in enhancing accuracy and streamlining management.

Conclusions:

• Targeted, technology-enhanced AF screening can benefit patients and healthcare systems by preventing strokes.
• Successful implementation requires balancing improved detection against risks of overdiagnosis and system costs.
• Integrating novel technologies with evidence-based pathways is essential for sustainable impact.
