Participants were evaluated using standard protocols at 6-to-12-month intervals. The following events were assessed: (1) atrial tachyarrhythmia (including atrial fibrillation and supraventricular tachycardia); (2) ventricular tachyarrhythmia and (3) bradycardia\/pacemaker. The cumulative incidence rate (CIR) of each arrhythmia was calculated. Cox proportional hazards models (reported as the current level HR (measured just prior to the event) and the adjusted mean HR) were fitted to assess the association between selected measures of PsA disease activity and the age of occurrence of arrhythmia events. Each model was adjusted for sex, PsA duration, cardiovascular risk factors and medications.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 1670 patients with PsA were analysed (80 atrial tachyarrhythmias, 17 bradyarrhythmias\/pacemakers and 11 ventricular tachyarrhythmias). By age 70, the CIRs were 7.82%, 0.67% and 0.45% for atrial, ventricular and bradycardia, respectively. In multivariable analysis, remission\/low versus high disease activity state was associated with lower risk of atrial tachyarrhythmia (current HR 0.49, 95%\u2009CI 0.26 to 0.92; adjusted mean HR 0.46, 95%\u2009CI 0.23 to 0.91). Similarly, a higher three-item Visual Analogue Scale (3-VAS) was associated with a higher risk of atrial tachyarrhythmia (current level HR 1.18, 95%\u2009CI 1.04 to 1.33; adjusted mean HR 1.22, 95%\u2009CI 1.04 to 1.44).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Higher PsA disease activity is associated with higher atrial tachyarrhythmia risk.
