In a groundbreaking initiative, Leeds Teaching Hospitals NHS Trust is testing an AI tool designed to identify individuals at risk of developing atrial fibrillation (AF), a condition that significantly increases the likelihood of life-threatening strokes. The trial, which started in autumn 2023, aims to involve nearly 2,000 participants and is nearing completion.
Understanding Atrial Fibrillation and Its Risks
Atrial fibrillation is a common heart rhythm disorder that can lead to serious health complications, including strokes. In fact, individuals with AF are five times more likely to experience a stroke, making early detection and intervention crucial. Approximately 1.6 million people in the UK are diagnosed with AF, but many others remain undiagnosed, potentially contributing to around 20,000 strokes annually.
The Role of the FIND-AF Algorithm
The innovative algorithm, known as FIND-AF, utilizes machine learning to analyze GP records for indicators that suggest a person may develop AF within six months. Patients flagged by the algorithm are subsequently offered further testing to confirm a diagnosis.
Professor Chris Gale, an honorary consultant cardiologist at Leeds Teaching Hospitals NHS Trust, emphasized the importance of early detection: “All too often, the first sign that someone is living with undiagnosed atrial fibrillation is a stroke. This can be devastating for patients and their families.”
How the Trial Works
As part of the trial, FIND-AF has been deployed across several GP surgeries in West Yorkshire. Patients identified as being at risk are provided with at-home testing options, which include:
- At-Home ECG Testing: Individuals receive a handheld electrocardiogram (ECG) device to monitor their heart rhythm. They are instructed to take two readings daily for four weeks and whenever they experience palpitations.
- Remote Monitoring: This approach allows patients to manage their health from the comfort of their homes without needing to visit a GP surgery.
If the ECG readings indicate AF, the patient’s GP is notified, enabling timely discussions regarding treatment options.
Funding and Future Plans
The trial is supported by the British Heart Foundation and Leeds Hospitals Charity. Once completed, Leeds Teaching Hospitals NHS Trust intends to share the findings with the West Yorkshire Integrated Care Board (ICB) to promote wider implementation across the region.
Professor Gale has expressed a desire to collaborate with the NHS and other healthcare providers to expedite the adoption of this innovative diagnostic tool, aligning with the government’s goal of transitioning from reactive to proactive healthcare.
Conclusion: A New Era in Stroke Prevention
The FIND-AF trial represents a significant step forward in the fight against atrial fibrillation and its associated risks. By harnessing the power of AI to detect AF early, the initiative could potentially save thousands of lives and reduce the healthcare costs associated with untreated conditions. As the trial concludes, its findings may pave the way for a broader rollout, marking a new era in stroke prevention strategies in the UK.
