Abstract

BACKGROUND: Atrial fibrillation (AF) is the most common rhythm disturbance seen in clinical practice. Evidence emerged that suggested inflammation was associated with risk of AF. Helicobacter pylori (HP) cause gastric and esophageal inflammation, as well as systemic and vascular inflammation. These local and systemic inflammatory effects may increase the risk of AF. The pathogenesis of atrial fibrillation (AF) remains unknown. However, many recent studies point to an association between AF and inflammation because of a demonstrable significant correlation between the dysrhythmia and various biomarkers of inflammation. Given the suggested involvement of inflammation with this dysrhythmia, an initiating factor for inflammation has been sought. Chronic bacterial infection is the most likely event to initiate and maintain an inflammatory process. Recently, bacterial infections have been hypothesized to be involved in the pathogenesis of aF, and Helicobacter pylori and Chlamydia pneumoniae are two bacteria that have aroused interest. the aim of this study was to compare the prevalence of H. Pylori infection, proven by gastric biopsy, between aF patients and control group and the role of CRP, MPV, age and sex in patients with HP associated AF. METHODS: We investigated one hundred eighty patients with HP in whom gastroscopy was done and/or urea breathe test because of dyspepsia and epigastric discomfort for eventual detecting the presence of H. pylori infection, and the prevalence of fibrillation in patients with HP, and whether age, sex, inflammatory markers are different in the two groups. the study was enrolled in the Department of internal Medicine, Ziv Medical Center, safed, israel, from 2015 until 2019. RESULTS: The prevalence is more pronounced in men with both atrial fibrillation and H. pylori, in terms of age we see that the incidence of atrial fibrillation is more relative in the older age P<0.001. There is no statistically significant difference in the inflammatory marker MPV between the two groups P<0.005. The levels of high-sensitivity C-reactive protein (hs-CRP) have been shown to be higher among patients with H. pylori with aF compared with the control group HP without AF statistically significant P<0.001. CONCLUSIONS: There is a correlation between HP and AF, AF is more related to age and to an increased inflammation marker CRP in patients diagnosed with HP.
