Artificial intelligence is quietly reshaping how doctors screen for heart problems, turning routine tests into powerful early-warning systems. A new UK-developed AI model can spot subtle signs of two common heart conditions from standard electrocardiogram (ECG) tracings—potentially flagging people who need urgent follow-up long before symptoms become dangerous.
Presented at the European Society of Cardiology’s annual meeting in Munich, the tool was trained on vast amounts of data and tested in a large clinical trial. Researchers say it could speed up access to confirmatory imaging and help clinicians prioritize patients most likely to have serious heart disease.

What the AI does differently with routine ECGs
The electrocardiogram records the heart’s electrical signals and is among the most frequently performed cardiac tests. Historically, ECGs have been used to diagnose arrhythmias and acute events, but they don’t reliably reveal structural heart disease. This AI model changes that by learning subtle patterns that humans can’t easily see.
- Trained on millions of records: The model learned from a huge dataset, allowing it to pick up minute ECG features linked to structural problems.
- Targets two major conditions: It is specifically designed to detect early signs of heart failure and heart valve disease from a standard ECG.
- Fast and scalable: Analysis of ECGs happens in seconds, which could be scaled across clinics and hospitals that already perform routine ECG testing.
Results from the large-scale clinical validation
In a clinical validation involving 67,000 U.S. patients whose ECGs were retrospectively analyzed, the AI demonstrated strong detection performance. The model identified roughly eight out of ten cases of heart failure and nine out of ten cases of valve disease—figures that suggest real-world utility for triage and early detection.
Key performance figures
- Detected about 81% of heart failure cases in the trial cohort.
- Detected about 90% of heart valve disease cases.
- Designed to flag potential problems rather than provide a definitive diagnosis—positive AI findings would trigger expedited imaging like an echocardiogram.
How this could change patient pathways and waiting times
Echocardiography—an ultrasound of the heart—is the standard test to confirm structural disease but patients often face long waits for appointments. By using AI to triage routine ECGs, clinicians could speed up referrals for those at highest risk, cutting through backlogs and focusing limited imaging resources where they matter most.
- Many patients have ECGs for unrelated reasons; the AI could opportunistically screen those tracings for signs of structural disease.
- Positive AI results could be used to prioritize scheduling for echocardiograms, potentially moving at-risk patients to the front of the queue.
- The approach aims to reduce the number of undiagnosed cases that only surface after severe events such as sudden cardiac arrest.
Voices from the trial and its supporters
Clinical leaders involved in the project stressed the potential patient benefits while cautioning that the AI is not a standalone diagnostic tool. Dr. Sonya Babu-Narayan, a consultant cardiologist and the clinical director at the British Heart Foundation—which funded the trial—emphasized that earlier detection saves and improves lives and that AI could help identify those most in need of urgent assessment.
Professor Fu Siong Ng of Imperial College London, who contributed to the research, highlighted the practical advantage: many people already have ECGs recorded for other clinical reasons, so the AI could add a layer of screening without extra tests and flag unsuspected disease.
Practical considerations, limitations, and next steps
While the findings are promising, experts note several important caveats before widespread clinical adoption.
- Not a definitive test: An AI-flagged ECG points to increased risk and should prompt confirmatory imaging rather than immediate therapeutic action.
- Population and setting: The validation used retrospective ECGs from a U.S. cohort; further prospective trials in diverse healthcare settings will be needed to confirm generalizability.
- Integration challenges: Implementing AI into clinical workflows requires validation, regulatory approval, and careful planning so that flagged patients receive timely follow-up without overwhelming services.
Regulatory and ethical questions
Deploying an AI-driven triage system raises familiar concerns: how to manage false positives and negatives, how to ensure equitable performance across demographics, and how to inform patients when an algorithm identifies a potential problem. Ongoing trials and regulatory reviews will be crucial to determine the safest path forward.
Why this matters now for public health and cardiology
The ECG is one of the most commonly used cardiac tests worldwide—performed an estimated billion times each year—so augmenting its diagnostic reach with AI could have broad impact. Early identification of heart valve disease and heart failure offers a window for earlier intervention, which can reduce morbidity and improve outcomes if appropriate follow-up care is delivered in time.
- Resource efficiency: Using existing ECGs for additional screening could be a low-cost way to improve detection rates.
- Opportunity for opportunistic screening: Patients who undergo ECGs for other reasons could be simultaneously assessed for structural heart disease.
- Potential to save lives: Earlier detection could prevent catastrophic presentations that are often the first sign for many patients.
