Atrial fibrillation, arrhythmia burden and thrombogenesis

Area of Science:

• Cardiology
• Electrophysiology
• Thrombosis

Background:

• Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia, posing significant stroke and thromboembolism risks.
• The incidence and healthcare impact of AF are escalating globally.
• Quantifying AF disease burden was historically challenging but is now feasible with cardiac rhythm management devices.

Purpose of the Study:

• To review the current literature on the relationship between the amount of AF and thromboembolic risk.
• To clarify the clinical significance of device-detected atrial high-rate episodes.
• To provide an overview of how arrhythmia burden influences thrombogenesis and clinical thromboembolism.

Main Methods:

• Literature review of studies investigating AF burden and thromboembolism.
• Analysis of data from cardiac rhythm management devices.
• Synthesis of evidence on the impact of AF burden on thrombogenesis.

Main Results:

• Growing evidence links AF burden, measurable by devices, to thromboembolic events.
• Device-detected atrial high-rate episodes provide quantifiable metrics for AF burden.
• Understanding AF burden is crucial for assessing and managing thromboembolic risk.

Conclusions:

• Cardiac rhythm management devices enable more accurate assessment of AF burden.
• Quantified AF burden is clinically relevant for predicting thromboembolism.
• Further research into AF burden thresholds is essential for optimizing stroke prevention strategies.
