Using AI to analyze heart sounds and electrical signals for heart failure diagnosis

A Deep-learning-based Multi-modal Phonocardiogram(PCG) and Electrocardiogram(ECG) Processing Framework for Screening Depressed Left Ventricular Ejection Fraction (dLVEF) Using a Wearable Cardiac Patch

Observational Ruijin Hospital · NCT06009718

This study is testing if a new AI system can help doctors diagnose heart failure by analyzing heart sounds and electrical signals from patients who are already getting heart ultrasound tests.

What this trial studies

This observational study aims to develop an artificial intelligence (AI) system that analyzes synchronized phonocardiography (PCG) and electrocardiogram (ECG) data to identify patients with depressed left ventricular ejection fraction (dLVEF). Participants, aged 18 and older, who are scheduled for ultrasound cardiography (UCG) at RuiJin Hospital, will wear a device that records PCG and ECG simultaneously. The study seeks to create machine learning algorithms that can accurately diagnose dLVEF, potentially improving access to timely treatments and reducing the need for expensive testing. By accumulating large datasets of acoustic data, the study aims to enhance diagnostic capabilities in primary care settings.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who are attending RuiJin Hospital for ultrasound cardiography.

Not a fit: Patients with pacemakers or significant conduction abnormalities may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to faster and more accurate diagnoses of heart failure, enabling timely interventions.

How similar studies have performed: While the use of AI in cardiac diagnostics is emerging, this specific approach of combining PCG and ECG analysis is relatively novel.
