Abstract

Background: Social phobia shares symptoms with arrhythmias, such as palpitations and chest discomfort. However, it is unclear how social phobia is associated with the actual risk of arrhythmia. This study aimed to investigate whether social phobia is associated with the risk of arrhythmia using a nationally representative sample cohort. Methods: This retrospective cohort study assessed data from the 2002–2013 Korean National Health Insurance Service National Sample Cohort. Using 1:3 propensity score matching for sex, age, income, and insurance status, 1514 patients with social phobia and 4542 control group patients were included in the study. Social phobia and arrhythmia were defined per the International Classification of Diseases, 10th revision. Using cox proportional hazard regression, hazard ratios (HRs) were calculated to estimate the risk of arrhythmia in patients with social phobia. Results: There were statistically significant associations between social phobia history and elevated risks of arrhythmia. Patients with social phobia had a higher risk of arrhythmia after adjusting with covariates (HR = 1.78, 95%CI = 1.25–2.55). Among different types of arrhythmias, atrial fibrillation and flutter presented the highest risk (HR = 2.20, CI = 1.06–4.57) compared to paroxysmal tachycardia (HR = 1.07, CI = 0.39–2.91) and other cardiac arrhythmias (HR = 1.83, CI = 1.16–2.89). Conclusion: This study identified the association between social phobia and the risk of arrhythmia in a South Korean representative cohort. These results suggest that social phobia should be treated properly to reduce arrhythmia risks.
