Objectives To systematically review the relationship between hypothyroidism and the risk of atrial fibrillation.Method PubMed, EMbase, The Cochrane Library, Web of Science, CNKI, CBM, VIP and WanFang Data databases were electronically searched to collect cohort and case-control studies on the association between hypothyroidism and atrial fibrillation from inception to November 2019. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was then performed using RevMan 5.3 software.Results A total of 5 cohort studies involving 574 268 subjects and 18 059 atrial fibrillation cases were included. The results of meta-analysis showed that hypothyroidism was not associated with atrial fibrillation (OR=1.10, 95%CI 0.75 to 1.61, P=0.62). From subgroup analysis, no relationship was identified in community population (OR=0.97, 95%CI 0.72 to 1.29, P=0.82) and cardiac surgery patients (OR=1.22, 95%CI 0.58 to 2.53, P=0.60).Conclusions Hypothyroidism does not increase the risk of atrial fibrillation. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusions.
