title: Proton pump inhibitors as also inhibitors of atrial fibrillation.
abstract: Proton pump inhibitors (PPIs) are widely used for the treatment of acid-related upper digestive diseases, including gastric and duodenal ulcer and gastroesophageal reflux disease (GERD). Remarkably, several small clinical trials have shown that these drugs also reduce the symptoms and frequency of atrial fibrillation (AF) episodes in patients treated for comorbid acid reflux. Although the mechanism remains unclear, the effect might pinpoint a connection between GERD and AF. To this end, it is known that both oxidants and inflammation affect initiation and maintenance of AF, and PPIs may reduce symptoms and frequency of AF episodes through their antioxidant and anti-inflammatory effects. This review focuses on the anti-AF effects of PPIs beyond their inhibition of gastric acid production.
