Hypothesis-generating for autophagy-immune pathways in post-valvular AF; requires experimental validation before clinical relevance.
Observational (n=19)
This bioinformatics analysis identifies specific autophagy-related genes and immune cell subpopulations that may play a critical role in the development of atrial fibrillation following valvular heart disease.
Liu et al. (2021) conducted an observational in Valvular atrial fibrillation (n=19). Atrial fibrillation following valvular heart disease vs. Normal sinus rhythm was evaluated on Differentially expressed autophagy-related genes and immune cell infiltration. Bioinformatics analysis identified six autophagy-related genes (BECN1, GAPDH, ATG7, MAPK3, BCL2L1, and MYC) and three immune cell subpopulations as significant potential regulators in atrial fibrillation following valvular heart disease.
