Objectives: The aim of this study is to assess the association between atrial fibrillation (AF) and sudden sensorineural hearing loss (SSNHL).
Methods: This study was conducted by searching the longitudinal health insurance database of the Taiwan National Health Insurance Program for relevant information from January 1, 2000, to December 31, 2011. Patients with AF were matched with non-AF controls with a 1:1 strategy according to propensity scores. Multiple logistic regression analyses were performed to determine the risk of SSNHL.
Results: In total, 14 698 patients with AF were matched with the same number of non-AF patients as controls. After propensity score matching, the use of antiplatelet or anticoagulation medications and the occurrence of SSNHL were found to have a significant difference between AF and non-AF patients. The occurrence of SSNHL was found to be higher in men, those of 45 to 74 years old, and patients with hypertension in both AF and non-AF groups. Multiple logistic regression analyses revealed that male gender, age between 45 and 74 years, hyperlipidemia, and hypertension are risk factors for SSNHL. The use of aspirin was found to reduce the rate of SSNHL (odds ratio [OR]: 0.67, 95% CI: 0.49-0.94, P = .019), but AF was not found to be a risk factor for SSNHL (OR: 0.89, 95% CI: 0.64-1.23, P = .467).
Conclusion: The association between AF and SSNHL is not significant.
