Background: Ischemic heart disease (IHD) has emerged as a major cause of morbidity and mortality in patients with autoimmune conditions such as systemic lupus erythematosus and rheumatoid arthritis, but the risk of IHD in Sjögren's syndrome (SjS) is unknown. To fill this knowledge gap, we estimated the prevalence and risk of IHD with SjS compared to controls from the general population using the Healthcare Cost and Utilization Project National Inpatient Sample 2011 database. Materials and Methods: The Healthcare Cost and Utilization Project administrative longitudinal database contains encounter-level information on inpatient stays, emergency department visits and ambulatory surgery in all U.S. hospitals. We conducted a cross-sectional study among the inpatient population diagnosed with SjS and matched 1:4 with controls for age, sex and hospital region. Odds ratio for IHD was calculated as cases compared to controls. The contribution of various risk factors to IHD was also evaluated by logistic regression. Results: Analysis demonstrated that 7,154 of 13,086 cases (54.7%) of SjS had IHD compared to 27,367 of 52,448 controls (52.2%). The adjusted odds ratio for IHD in those with SjS was 0.898 (95% CI: 0.844-0.955). Patients with SjS were significantly more likely to have hypertension, diabetes, apnea and lipid disorders. Conclusions: To our knowledge, this is the largest population-based study investigating the risk of IHD in patients with SjS. We found a modest, though statistically significant, decrease in the risk of IHD in SjS compared to controls.
