Association of Serum Myonectin Concentrations With the Presence of Atrial Fibrillation

Abstract

Objective: Myonectin, a recently found myokine, has a role of inhibiting inflammation. The aim of this research is to see if myonectin levels are linked to the occurrence of atrial fibrillation (AF).Methods: We examined serum myonectin in a population of 194 patients with AF who were then classified into three subgroups: paroxysmal AF, persistent AF, and permanent AF. Atrial remolding was assessed using left atrial diameter (LAD). Results: Serum myonectin was significantly lower in AF group compared with healthy controls. Logistic regression analysis demonstrated that serum myonectin concentrations were correlated with a decreased risk of AF. Patients with permanent AF displayed decreased serum myonectin than in persistent and paroxysmal AF groups. Serum myonectin was lower in persistent AF group than in paroxysmal AF group. Serum myonectin concentrations in AF patients were negatively associated with body mass index (BMI), systolic blood pressure, diastolic blood pressure, and LAD. BMI and LAD stayed to be correlated with serum myonectin according to multiple stepwise regression analysis. Conclusion: Our study demonstrated a correlation between serum myonectin and AF.
