Using smartwatches and Holter monitors to find hidden atrial fibrillation in stroke patients

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to determine if long-term monitoring with wearable devices, such as smartwatches and external Holter monitors, can detect more cases of occult atrial fibrillation (AF) in patients who have experienced a cryptogenic stroke compared to traditional 30-day monitoring. The study will involve patients aged 55 and older who have had a stroke, and will assess the effectiveness of smartwatches against insertable cardiac monitors. Additionally, it will evaluate patient adherence to using these devices and identify predictors of long-term AF and vascular events.

Why it matters

Who can join: the full rules

Inclusion Criteria:

* Age greater to or equal to 55 years
* Patients with diagnosis of cryptogenic stroke after a basic study that included neuroimaging, extra/intracranial vascular evaluation, 24-hour monitoring, and echocardiogram
* Patients with acute cortical infarction with the presence of intracranial occlusion (preferably)
* Modified Rankin Scale (mRS) lower to 4

Exclusion Criteria:

* Diagnosis of lacunar infarction or transient ischemic attack (TIA)
* Diagnosis of stroke of known source: atherothrombotic due to moderate or severe symptomatic extra/intracranial stenosis, major cardioembolic cause (atrial fibrillation, anterior or apical ventricular akinesis, causal PFO, post-AMI, flutter or mitral stenosis), unusual cause (thrombophilia, arterial dissection symptomatic, toxic)
* Use of pacemakers
* Circumstances that may preclude the clinical follow-up or reduce the possibilities of obtaining data to achieve the objectives of the study and/or limit contact with the investigator (for example, transfer to a social health center)
* Unwillingness to the use of cardiac monitoring wearable devices
* Not understanding study procedures
