Session Type: ACR Poster Session A
Session Time: 9:00AM-11:00AM
To examine the risk of atrial fibrillation (AF) at the time of first diagnosis of gout compared to matched controls and to follow incident gout patients and their matched controls after diagnosis to compare their subsequent risk of AF.
45,378 incident gout patients and 45,378 age-, sex-, practice-, registration year- and index year-matched controls were identified from the UK Clinical Practice Research Data-link. Index dates were initial diagnosis date for gout patients and their matched controls. The risk of AF at diagnosis (odds ratios [ORs], using conditional logistic regression) and after the diagnosis of gout (hazard ratios [HRs], using Cox proportional models) were estimated, adjusted for body mass index, smoking, alcohol consumption, ischaemic heart disease, heart failure, heart valve disease, hyperthyroidism and other comorbidities and medications.
The prevalence of AF at index date in gout patients (male, 72.3%; mean age, 62.4 ± 15.1 years) was 7.42% (95% confidence interval [CI], 7.18%–7.66%) and in matched controls 2.83% (95% CI, 2.67%–2.98%). The adjusted OR (95% CI) was 1.45 (1.29–1.62). The cumulative probability of AF at 1, 2, 5 and 10 years after index date was 1.08%, 2.03%, 4.77% and 9.68% in gout patients and 0.43%, 1.08%, 2.95% and 6.33% in controls (log-rank test, p < 0.001). The adjusted HRs (95% CIs) was 1.09 (1.03–1.16).
This population-based study indicates that gout is independently associated with a higher risk of AF at diagnosis and the risk is also higher after the diagnosis.
