Abstract
INTRODUCTION
Atrial Fibrillation (AF) is the most prevalent cardiac arrhythmia worldwide. Inflammation and structural remodeling of the left atrium are thought to be involved in the pathogenesis of AF. This study explores collagen remodeling and inflammatory biomarkers in AF patients compared to healthy controls to discern their role in AF.
MATERIALS AND METHODS
Plasma samples were collected from AF patients undergoing first AF ablation (n = 72) and compared with commercially available human plasma samples from healthy subjects (n = 62). The collagen remodeling biomarkers and inflammatory biomarkers in the AF patients and control population were quantified using sandwich ELISA kits. GraphPad prism was used to perform statistical analyses.
RESULTS
There was a statistically significant elevation in all the collagen remodeling biomarkers and inflammatory biomarkers in the AF patients compared to healthy controls. Spearman correlation analysis demonstrated significant correlations between inflammatory and collagen remodeling biomarkers, and among the collagen biomarkers. Of note, CRP was found to be correlated with TIMP-1, ICTP and PIIINP. IL6 and TIMP-1 were also found to be intercorrelated. Furthermore, correlations were noted among the different collagen remodeling peptides, and between TNFα and IL6, two of the inflammatory markers explored in this study.
CONCLUSIONS
The elevation of the inflammatory biomarkers and collagen remodeling proteins in AF patients is suggestive of inflammation and increased collagen turnover. The association between inflammatory biomarkers and collagen remodeling proteins may contribute to their regulation and role in the remodeling process.
