Rheumatoid arthritis and the risk of ischaemic stroke after diagnosis of atrial fibrillation: a Norwegian nationwide register study.

ABSTRACT:

Objectives

RA patients have an increased risk for cardiovascular diseases, including atrial fibrillation (AF), but the impact of RA on ischaemic stroke risk in the context of AF remains unknown. We explored whether the risk of ischaemic stroke after diagnosis of AF is further increased among patients with RA compared with non-RA patients.

Methods

In the nationwide Norwegian Cardio-Rheuma Register, we evaluated cumulative incidence and hazard rate of ischaemic stroke after the first AF diagnosis (2750 individuals with RA and 158 879 without RA between 2010 and 2017) by using a competing risk model with a 3-month delayed entry.

Results

The 5-year unadjusted cumulative incidence of ischaemic stroke was 7.3% (95% CI: 5.9-8.7%) for patients with RA and 5.0% (95% CI: 4.9-5.
