The aim of this study is to investigate the association between APS and atrial fibrillation (AF) among patients in Peking University People\u2019s Hospital. A single center retrospective study was conducted. Cases were hospitalized patients diagnosed with AF by a cardiologist while the control group patients did not exhibit cardiac diseases. The results of the study revealed that in multivariable logistic regression, APS, anticardiolipin antibody (aCL) positivity and anti-beta-2-glycoprotein antibody (anti-<jats:italic>\u03b2<\/jats:italic>2GPI) positivity are independent risk factors of AF. APS, aCL positivity and anti-<jats:italic>\u03b2<\/jats:italic><jats:sub>2<\/jats:sub>GPI positivity are statistically different between AF patients and non-AF patients. Forthcoming studies are needed to clarify the potential link between APS and
