The overarching goal for this project is to compare Norwegian data (2008-2017) on cardiovascular diseases (CVD) in patients with inflammatory joint diseases (IJD) (rheumatoid arthritis, ankylosing
spondylitis and psoriatic arthritis) with similar Finnish register data from 2008-2017. First, data on the hypotheses in the Norwegian patients with IJD and general population controls are being explored, and secondly the results will be validated with data from the Finnish registers.
The objectives include
1) to evaluate all-cause and CVD morbidity and mortality in patients with IJD compared to the general population,
2) to compare the prevalence of CVD in users and non-users of biologic disease-modifying antirheumatic drugs (bDMARDs) in patients with IJD and the general population,
3) to explore sex differences in CVD event rates in patients with IJD compared to the general population.
