Is this trial a fit for you?

Likely a good fit

Adults 18 years or older with atrial fibrillation on DOAC therapy, able to provide informed consent, and able to complete at least 3 months of follow-up.

Probably not a fit

Patients with valvular AF or mechanical valve prostheses or those unable to complete 3 months of follow-up may not benefit from this score.

What this trial studies

This observational study examines whether a predefined risk score can identify the likelihood of embolic events in adults with atrial fibrillation who are being treated with DOACs. Participants must be at least 18 years old, have a history of atrial fibrillation, and be on a DOAC, with informed consent and ability to complete follow-up for at least 3 months. Patients with valvular AF or mechanical valves are excluded. Data are collected to correlate DOAC therapy with stroke or embolism risk and to evaluate the score's predictive usefulness in this setting. The study is led by Hospital Universitari Vall d'Hebron Research Institute with collaboration from two Barcelona hospitals at present.

Why it matters

Potential benefit: If successful, the risk score could help clinicians better identify AF patients on DOACs who are at higher risk of embolism.

How similar studies have gone: Previous research has shown promise for risk scoring in AF, but validation in DOAC-treated populations varies; this study builds on that foundation with a real-world observational approach.
