Key result
Subclinical atrial fibrillation detected by implantable cardiac devices increases stroke risk with an odds ratio of 2.2 to 3.1 compared to patients without recorded subclinical atrial fibrillation.
Why the study?
Does the detection of subclinical atrial fibrillation using implanted devices help in primary and secondary stroke prevention?
Does the detection of subclinical atrial fibrillation using implanted devices help in primary and secondary stroke prevention?
Subclinical atrial fibrillation detected by implantable cardiac monitors is associated with a 2- to 3-fold increased risk of stroke, highlighting its emerging role in guiding anticoagulation for stroke prevention.
Device-detected subclinical AF warrants caution in stroke risk assessment; leaves open whether anticoagulation improves primary prevention outcomes.

Chu‐Pak Lau (2015) conducted a review in Cryptogenic stroke and subclinical atrial fibrillation. Implantable cardiac electronic devices (CIEDs) and insertable cardiac monitors (ICMs) vs. Standard monitoring or no subclinical atrial fibrillation was evaluated. Subclinical atrial fibrillation detected by implantable cardiac devices increases stroke risk with an odds ratio of 2.2 to 3.1 compared to patients without recorded subclinical atrial fibrillation.
