Background The associations between premature atherosclerosis and immune-mediated inflammatory diseases (IMIDs) are not fully investigated. To determine whether IMIDs are associated with premature atherosclerosis, we examined the risk of incident coronary artery disease (CAD) in men less than 45 years old and women less than 50 years old with various forms of IMIDs compared with general population. Methods A population-based cohort was established and included patients with IMID, who were followed until the development of CAD, withdrawal from the insurance system, death, or 31 December 2016, whichever point came first. Patients with IMID included rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), primary Sjogren's syndrome (SjS), idiopathic inflammatory myositis, systemic sclerosis (SSc), Behcet's disease (BD), and systemic vasculitis (SV). The comparison group was 1 000 000 beneficiaries sampled at random from the whole population as matched control participants. The Kaplan-Meier method was used to compare the cumulative incidences of CAD in patients with and without IMID. Results Among 58 862 patients with IMID, 2139 (3.6%) developed CAD and 346 (1.3%) developed premature CAD. Relative to the comparison cohorts, the adjusted HRs for premature CAD were 1.43 (95% CI 1.09 to 1.86) for primary SjS, 2.85 (95% CI 2.63 to 3.43) for SLE, 3.18 (95% CI 1.99 to 5.09) for SSc and 2.27 (95% CI 1.01 to 5.07) for SV. Conclusions Primary Sjogren's syndrome, SLE, SSc and SV are associated with an increased risk of premature CAD. Our fi ndings will support essential efforts to improve awareness of IMID impacting young adults.
