AIMS: To investigate whether incident atrial fibrillation or flutter (AF) diagnosis increases the risk of psychiatric outcomes compared with the general population.

METHODS AND RESULTS: First-time AF patients and population controls naive to psychiatric disease or filled prescriptions for psychotropic drugs were identified in Danish nationwide registries during 2005-14. AF patients were matched 1:2 with exposure density matching. Patients and controls were compared for 1-year cumulative incidences of depression, anxiety, and stress disorders, and for filled drug prescriptions for antidepressant, anxiolytic, selected antipsychotics, and hypnotics. Lastly, we examined 1-year cumulative incidences of a composite endpoint of the above-mentioned diagnoses or drug redemptions. We included 146 377 AF patients and 292 754 matched controls, 55% men and median age 74 (25-75% 65-82) years. AF patients had significantly higher cumulative incidences of composite endpoints. Furthermore, filled prescriptions for anxiolytics and hypnotics were significantly higher for AF patients compared with healthy population controls. The cumulative incidence of the composite endpoint was significantly higher in AF patients relative to controls 11.1% vs. 8.3%. For the composite endpoint, a significantly higher risk was apparent both in unadjusted (HR: 2.76, 95% CI: 2.67-2.85) and adjusted (HR: 2.51, 95% CI: 2.43-2.60) models for AF patients vs. controls in the first 3 months after study inclusion.

CONCLUSION: First-time AF patients were significantly more likely to have psychiatric outpatient or hospital contacts and to fill prescriptions for psychotropic drugs compared with healthy population controls. The risk was significantly elevated only during the first 3 months after AF diagnosis.
