Using machine learning to improve treatment for atrial fibrillation

Machine Learning in Atrial Fibrillation

Observational Stanford University · NCT05371405

This study is testing if using machine learning can help doctors better understand and treat atrial fibrillation by looking at patient data from those who have had ablation.

What this trial studies

This project investigates how machine learning can enhance the understanding and treatment of atrial fibrillation (AF) by analyzing physiological data and outcomes from patients undergoing ablation. The study aims to identify specific electrical and structural features that influence the success of AF ablation, utilizing a combination of computational techniques and clinical data. By recruiting 120 patients, the research will focus on three main objectives: analyzing electrograms to predict outcomes, assessing the acute response to ablation, and determining long-term success rates of the procedure. The findings could lead to more personalized treatment strategies for AF patients.

Who should consider this trial

Good fit: Ideal candidates are patients undergoing ablation for paroxysmal or persistent atrial fibrillation who have failed or are intolerant to at least one anti-arrhythmic drug.

Not a fit: Patients with active coronary ischemia, decompensated heart failure, or other specified exclusion criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more effective and personalized treatment options for patients with atrial fibrillation.

How similar studies have performed: Other studies have shown promise in using machine learning for similar applications in cardiac care, suggesting potential for success in this approach.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* undergoing ablation at Stanford of (a) paroxysmal AF (self-terminates \< 7 days), or (b) persistent AF (requires cardioversion to terminate).
* Per our clinical practice and guidelines (Calkins et al, Heart Rhythm 2012), patients will have failed or be intolerant of ≥ 1 anti-arrhythmic drug.

Exclusion Criteria:

* active coronary ischemia or decompensated heart failure
* atrial or ventricular clot on trans-esophageal echocardiography
* pregnancy (to minimize fluoroscopic exposure)
* inability or unwillingness to provide informed consent
* rheumatic valve disease (results in a unique AF phenotype)
* thrombotic disease or venous filters
