Abstract: Objective To analyze the potential molecular mechanism of coronary heart disease induced by biorhythm disorder. Methods GSE71226 dataset was downloaded from Gene Expression Omnibus(GEO). R software was used to identify coronary heart disease differentially expressed genes(CHD-DEGs), through text mining and protein interaction analysis, biological clock related genes(BRGs)were obtained, and functional annotation, chromosome location and interaction analysis were carried out. Results 488 CHD-DEGs and 64 BRGs were obtained, which densely distributed on chromosomes, mostly related to transcription regulation, inflammation and immune system diseases. Among them, 28 CHD-DEGs interacted significantly with 22 BRGs, and there were 10 important associated target genes. Conclusion Biological rhythm disorder is closely related to the occurrence of coronary heart disease.
