Cryptogenic Stroke and Underlying Atrial Fibrillation

New England Journal of Medicine, 2014
Current guidelines recommend at least 24 hours of electrocardiographic (ECG) monitoring after an ischemic stroke to rule out atrial fibrillation. However, the most effective duration and type of monitoring have not been established, and the cause of ischemic stroke remains uncertain despite a complete diagnostic evaluation in 20 to 40% of cases ...

WATCH AFib: smartwatches for detection of atrial fibrillation in secondary prevention of cryptogenic stroke—protocol for a prospective, intraindividual-controlled, multicentre clinical study [PDF]

Frontiers in Neurology
RationaleDetection of atrial fibrillation (AFib) and subsequent anticoagulation therapy reduce the risk of recurrent stroke, while prolonged rhythm monitoring significantly increases AFib detection.

Atrial Fibrillation Detection and Ischemic Stroke Recurrence in Cryptogenic Stroke: A Retrospective, Multicenter, Observational Study

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Atrial fibrillation (AF) is known to be a strong risk factor for stroke. However, the risk of stroke recurrence in patients with cryptogenic stroke with AF detected after stroke by an insertable cardiac monitor (ICM) is not well known.

Stroke Prevention After Cryptogenic Stroke [PDF]

Current Cardiology Reports, 2021
Cryptogenic stroke represents a heterogenous but clinically important collection of stroke etiologies for which our understanding continues to grow. Here, we review our current knowledge and most recent recommendations on secondary prevention for common causes of cryptogenic stroke including paroxysmal atrial fibrillation, atrial cardiopathy, patent ...

Platelet function suggests cardioembolic aetiology in cryptogenic stroke

Scientific Reports, 2023
Platelet-monocyte (PMA) and platelet-neutrophil aggregations (PNA) play critical roles in the evolution of acute ischemic stroke (AIS). The present study investigates the mechanistic basis of platelet responsiveness in cryptogenic stroke compared with ...

Left atrial appendage volume increased in more than half of patients with cryptogenic stroke. [PDF]

PLoS ONE, 2013
BACKGROUND: Ischemic strokes without a well-defined etiology are labeled as cryptogenic, and account for 30-40% of strokes in stroke registries.

Uncommon Female-Predominant Etiologies of Cryptogenic Stroke

Frontiers in Neurology, 2022
The etiologies of cryptogenic stroke are complex and heterogeneous. A number of uncommon etiologies are not fully recognized, some of which predominantly affect females.

Atrial Cardiopathy and Cryptogenic Stroke [PDF]

Frontiers in Neurology, 2022
Recent advances in pathophysiology suggest that a pathological atrial substrate can cause embolic stroke even in patients without atrial fibrillation (AF). This pathological condition is called “atrial cardiopathy”, which indicates atrial structural and functional disorders that can precede AF.

Underlying causes of cryptogenic stroke and TIA in The Nordic Atrial Fibrillation and Stroke (NOR-FIB) Study – the importance of comprehensive clinical evaluation

BMC Neurology, 2023
Background Cryptogenic stroke is a heterogeneous condition, with a wide spectrum of possible underlying causes for which the optimal secondary prevention may differ substantially. Attempting a correct etiological diagnosis to reduce the stroke recurrence

Secondary Stroke Prevention Following Embolic Stroke of Unknown Source in the Absence of Documented Atrial Fibrillation: A Clinical Review

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Approximately one‐third of ischemic strokes are classified as cryptogenic strokes. The risk of stroke recurrence in these patients is significantly elevated with up to one‐third of patients with cryptogenic stroke experiencing a further stroke within 10 ...
