A new artificial intelligence tool is being tested in West Yorkshire to identify patients at risk of atrial fibrillation (AF) before symptoms appear by analyzing GP records.

The innovation at hand; The AI algorithm, developed by researchers at the University of Leeds and Leeds Teaching Hospitals NHS Trust, searches through medical records for warning signs of potential AF development.

  • The tool analyzes patient data including age, sex, ethnicity, and existing medical conditions like heart failure, high blood pressure, and diabetes
  • The project, called Find-AF, is being funded by the British Heart Foundation and Leeds Hospitals Charity
  • Initial trials are taking place at several GP surgeries in West Yorkshire, with hopes to expand nationwide

Current state of AF in the UK; Atrial fibrillation affects approximately 1.6 million diagnosed individuals in the UK, with potentially thousands more unaware they have the condition.

  • AF causes irregular and abnormally fast heart rates, significantly increasing stroke risk
  • The condition is estimated to contribute to around 20,000 strokes annually in the UK
  • Early detection and treatment can effectively manage AF and reduce stroke risk

Real-world impact; The trial has already demonstrated success in identifying at-risk patients who were previously unaware of their condition.

  • John Pengelly, a 74-year-old former Army captain, was diagnosed with AF through the trial despite having no symptoms
  • Pengelly now takes daily medication to manage his condition and reduce stroke risk
  • His case exemplifies the potential benefits of early detection through AI screening

Expert perspectives; Healthcare professionals emphasize the importance of early detection in preventing severe outcomes.

  • Professor Chris Gale notes that for many patients, their first indication of AF is a devastating stroke
  • Dr. Ramesh Nadarajah expresses hope that the West Yorkshire study will lead to broader implementation across the UK
  • Medical experts anticipate this approach will increase early AF diagnosis rates and enable timely preventive treatment

Future implications; The successful implementation of this AI tool could transform how healthcare systems approach AF detection and prevention, potentially reducing the burden of stroke-related disabilities and deaths while demonstrating the practical benefits of AI in preventive healthcare.
