Evaluation of New Potential Inflammatory Markers in Patients with Nonvalvular Atrial Fibrillation.

Atrial fibrillation (AF), the most common arrhythmia in clinical practice, is associated with an increase in mortality and morbidity due to its high potential to cause stroke and systemic thromboembolism. Inflammatory mechanisms may play a role in the pathogenesis of AF and its maintenance. We aimed to evaluate a range of inflammatory markers as potentially involved in the pathophysiology of individuals with nonvalvular AF (NVAF).

Evaluation of serum haptoglobin levels and Hp1-Hp2 polymorphism in the haptoglobin gene in patients with atrial fibrillation.

Background: Atrial fibrillation (AF) is an arrhythmia that involves structural and electrophysiological abnormalities. Many of the AF-related clinical conditions are associated with an increase in inflammatory and oxidative factors. Haptoglobin (Hp) is an acute phase protein whose biological role is to promote clearance of free hemoglobin (Hb).

Comparison of Inflammatory Mediators in Patients With Atrial Fibrillation Using Warfarin or Rivaroxaban.

Atrial fibrillation (AF) is the most common arrhythmia associated with high risk of venous thromboembolism. Inflammatory mechanisms may be involved in the pathophysiology of AF and in the AF-related thrombogenesis, and patients with AF might benefit from the use of anticoagulants with anti-inflammatory properties. However, the evidence is still scarce, and it points out the need of trials seeking to investigate the levels of inflammatory mediators in patients with AF under different anticoagulant therapies.
