AI analysis of ECGs to detect structural heart disease

Prospective Evaluation of Artificial Intelligence-enhanced Electrocardiography for Detection of Structural Heart Disease

Observational Imperial College London · NCT07057466

This project will test whether AI can read traditional and wearable ECGs to find undiagnosed valve disease, pulmonary hypertension, and heart failure in adults.

What this trial studies

This observational, prospective study will collect ECGs from routine 12‑lead machines and portable devices (Apple Watch, Eko Core, AliveCor) alongside blood tests (NT‑proBNP) to see how well AI models identify structural heart disease. Participants are adults aged 18–90 without prior formal diagnoses of heart failure, pulmonary hypertension, or valvular heart disease. Previously developed AI models trained on retrospective data will be applied to the newly collected ECGs to estimate detection accuracy in a real‑world setting. Results will be compared with standard biomarkers and clinical data to determine whether AI can reliably flag patients who need further cardiac evaluation.

Who should consider this trial

Good fit: Ideal candidates are adults 18–90 who have no prior formal diagnosis of heart failure, pulmonary hypertension, or valvular heart disease and can provide informed consent.

Not a fit: Patients with prior diagnoses of heart failure, pulmonary hypertension, or valvular disease, those with unstable cardiovascular conditions, severe arrhythmias, or implanted pacemakers/ICDs are excluded and unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enable earlier and easier detection of serious heart conditions using routine or wearable ECGs, reducing missed diagnoses and preventing hospital admissions.

How similar studies have performed: Prior retrospective studies have shown promise for AI‑ECG detection of cardiac conditions, but prospective, real‑world validation remains limited.
