Atrial fibrillation (AF) remains the most common sustained cardiac arrhythmia with prevalence and incidence continuously increasing worldwide. Current guidelines propose an etiological, symptom-based classification of the arrhythmia and mainly focused on its duration with consequent rhythm or rate-control strategies. Moreover, risk scores for atherothrombotic systemic or hemorrhagic events related to atrial fibrillation are principally based on patients cardiovascular history and risk factors.
This approach do not consider relevant pathophysiological aspects that may play a pivotal role in triggering or perpetuating the arrhythmia, especially at its first occurrence. At this point, a crucial step would be deeply investigating AF clinical and pathophysiological features to guide a tailored diagnostical and therapeutic approach. Indeed, early recognition and proper characterization of triggers, substrates, autonomic system imbalance and modulating factors (drugs, electrolytes, etc) are of the utmost importance for AF care and management.
Therefore, this large scale prospective observational study aims to evaluate clinical and pathophysiological features of patients with symptomatic and asymptomatic atrial fibrillation in different scenarios to understand possible distinctive characteristics warranting a personalized approach to the arrhythmia.
