Study design:

Factorial 

研究目的:

通过16s测序和Elisa检测方法,对比术后房颤和非术后房颤患者术前的粪便拟杆菌水平、血浆中神经酰胺的水平,并与术后房颤进行相关性分析,探究肠道菌群、神经酰胺与术后房颤发生的相关性及可能机制。  

Objectives of Study:

By using 16s sequencing and Elisa methods, the levels of Bacteroides caccae in feces and ceramides in plasma of patients with postoperative atrial fibrillation and those without postoperative atrial fibrillation before surgery were compared, and a correlation analysis was conducted with postoperative atrial fibrillation to explore the correlation and possible mechanisms between the intestinal microbiota, ceramides, and the occurrence of postoperative atrial fibrillation.
