Abstract

Chronic inflammatory disorders like systemic lupus erythematosus (SLE) and rheumatoid arthritis are associated with worse outcomes in ischemic heart disease. However, there is a paucity of data regarding outcomes in patients with peripheral arterial disease (PAD) with concomitant SLE. The purpose of this study was to compare clinical features and in-hospital outcomes of PAD in patients with and without SLE from the general population using the Healthcare Cost and Utilization Project National Inpatient Sample database. We performed a cross-sectional analysis on 520,665 patients diagnosed with PAD from quarter 4 of 2015 to 2017. The primary endpoint was risk-adjusted in-hospital mortality. Of the total patient population, 3080 patients (0.6%) had SLE compared with 517,585 controls (99.4%). The observed in-hospital mortality was higher in patients with SLE (6.3% vs. 4.6%, P < 0.001). To the best of our knowledge, this is the largest population-based study investigating the impact of SLE in patients with PAD. Our analysis showed higher in-hospital mortality in SLE patients than in those without SLE. Early diagnosis and aggressive management of SLE and its complications in these patients have the potential to improve overall outcomes.
