Possible cross‑talk between atrial fibrillation and obstructive sleep apnea revealed by transcriptomic analysis
Background Clinical observational studies have demonstrated a high prevalence of obstructive sleep apnea (OSA) in patients with atrial fibrillation (AF), indicating a significant comorbidity between the two conditions. This study applies transcriptome data to investigate shared molecular mechanisms...

| description | Background Clinical observational studies have demonstrated a high prevalence of obstructive sleep apnea (OSA) in patients with atrial fibrillation (AF), indicating a significant comorbidity between the two conditions. This study applies transcriptome data to investigate shared molecular mechanisms underlying AF and OSA comorbidity and develops a robust diagnostic model to evaluate OSA risk in AF patients.Methods Transcriptomic datasets for AF (GSE79768) and OSA (GSE135917) were retrieved from the the Gene Expression Omnibus(GEO) database. Differentially expressed genes (DEGs) associated with OSA and AF comorbidity were identified using weighted gene co-expression network analysis (WGCNA). Protein-protein interaction (PPI) networks were constructed using Cytoscape, and hub genes were identified with the CytoHubba plug-in. A diagnostic model was then built based on these hub genes, and its performance was evaluated using receiver operating characteristic (ROC) curves in both the test and validation datasets. Immune cell infiltration analysis was conducted using CIBERSORT.Results A total of 1,462 differentially expressed genes (DEGs) were identified for the comorbidity of AF and OSA. Five hub genes were selected: IFNG, IL4, IL15, CD19, and FASLG. Immunoassay infiltration analysis revealed elevated levels of activated macrophages in both OSA and AF samples. The diagnostic model we developed demonstrated excellent predictive performance in the validation set.Conclusion We identified five hub genes common to both OSA and AF: IFNG, IL4, IL15, CD19, and FASLG. Moreover, a diagnostic model based on these five hub genes can predict the risk of OSA in patients with AF. |
