Using an implantable cardiac monitor to detect atrial fibrillation in stroke patients

Yield of Implantable Cardiac Monitoring Device in Patients With Acute Ischemic Stroke.

Not applicable Interventional National and Kapodistrian University of Athens · NCT05494034

This study is testing whether an implantable heart monitor can help find atrial fibrillation in stroke patients to see if it can lead to better treatment and prevent future strokes.

What this trial studies

This prospective cohort study aims to investigate the incidence of atrial fibrillation (AF) detected by an implantable cardiac monitoring device in patients who have experienced acute ischemic stroke. Conducted across four tertiary centers in the Athens Metropolitan area, the study will enroll consecutive patients aged 40 years or older diagnosed with acute ischemic stroke or transient ischemic attack (TIA). The research will focus on the association between detected AF, initiation of anticoagulation therapy, and the recurrence of stroke. The study will recruit approximately 200 eligible patients over a four-year period, ensuring informed consent is obtained from participants or their guardians.

Who should consider this trial

Good fit: Ideal candidates for this study are patients aged 40 years or older who have experienced an acute ischemic stroke or TIA and have a HAVOC score of 4 or higher.

Not a fit: Patients with known or newly detected atrial fibrillation at the time of hospitalization will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved detection and management of atrial fibrillation in stroke patients, potentially reducing the risk of stroke recurrence.

How similar studies have performed: Previous studies have shown success in using implantable cardiac monitors for detecting atrial fibrillation, indicating that this approach is promising.

Eligibility criteria

Inclusion Criteria:

* Consecutive acute ischemic stroke or TIA patients aged 40 years or older will be enrolled.
* Diagnosis of acute ischemic stroke will be based on clinical and neuroimaging evaluation \[brain computed tomography (CT) scan or magnetic resonance imaging (MRI) scan\].
* Stroke patients of all other etiologies (apart AF) presenting a HAVOC score ≥4 will be included in the study.
* Informed consent for participation in the study will be obtained from the patients or guardians of patients.

Exclusion Criteria:

* Patients with incomplete evaluation will be excluded, as previously described. \[22\] -Patients with known or newly detected AF at hospitalization will also be excluded.
* Not providing informed consent.
