Patients with chronic inflammatory rheumatic diseases, such as rheumatoid arthritis and spondyloarthritis, are at a higher risk of comorbidities, including cardiovascular disease. Although the prevalence of spondyloarthritis is estimated to be similar to that of rheumatoid arthritis, the risk of cardiovascular comorbidities in spondyloarthritis is not as well understood. Furthermore, the inflammatory rheumatic diseases differ in their pathogenic mechanisms, the populations affected, and treatment recommendations; therefore, it is important to examine these diseases separately. Ankylosing spondylitis (AS) is the prototype of spondyloarthritis; the onset of disease occurs at a relatively young age, and patients with AS are often undiagnosed for long periods of time. This increased duration of exposure to inflammation and use of nonsteroidal anti-inflammatory drugs may contribute to the higher risk of cardiovascular comorbidities in these patients.Here we describe our recently published study (Walsh JA, et al. Clin Rheumatol. 2018;37[7]:1869-1878.), which used large national claims databases and showed that US patients with AS had significantly more comorbidities, including cardiovascular disease, than matched controls. We also review the current understanding of the risk of cardiovascular comorbidities in patients with AS. Knowledge of the frequency and risk of comorbidities can assist rheumatologists and primary care physicians with comorbidity screening and strategies for a holistic care approach for patients with AS, including the possibility of adapting the existing cardiovascular risk assessments for these patients. Counseling patients on additional lifestyle risk factors, early cardiovascular screening, and the necessity of further diagnostic testing will be important for optimizing patient care for AS.
Cardiovascular Disease in Patients With Inflammatory Rheumatic DiseasesPatients with chronic inflammatory rheumatic diseases, such as rheumatic arthritis, spondyloarthritis, and systemic lupus erythematosus, have an increased risk of cardiovascular disease [1][2][3][4][5][6][7][8] . The increased cardiovascular risk in patients with inflammatory rheumatic disease is likely related to systemic inflammation and traditional cardiovascular risk factors, such as hypertension, dyslipidemia, diabetes, smoking, and obesity, some of which are more prevalent in patients with rheumatic diseases. A link between inflammation and accelerated atherosclerosis has been identified in patients with inflammatory rheumatic disease 9-11 . Furthermore, endothelial dysfunction, oxidative stress, macrophage accumulation, toll-like receptor signaling, and proinflammatory cytokines have been implicated in atherogenesis 9,11,12 . Similar to the heterogeneity in
