Awareness and perceived risk of cardiovascular disease among individuals living with rheumatoid arthritis is low: results of a systematic literature review

Background Individuals with rheumatoid arthritis (RA) are at risk of developing cardiovascular disease (CVD), but patient perceptions of CVD are not routinely assessed. We performed a systematic literature review to evaluate awareness of the association between RA and CVD, and perceived risk of CVD among individuals with RA. Methods Three electronic databases (MEDLINE, EMBASE, and PubMed) were searched for English language articles between the years of 1990–2018. Search terms pertained to RA, CVD, knowledge, awareness, or perceptions of CVD risk. Abstracts were screened for inclusion/exclusion by two independent reviewers. Results A total of 33 abstracts were screened and 6 underwent full review. The overall sample size was 478 subjects and included patients with established RA who were predominantly female with a mean age range of 53 to 64 years. RA disease characteristics relevant to CVD were not uniformly reported, including the use of DMARDs, corticosteroids, or NSAIDs. A high proportion of subjects (range 73 to 97%) were unaware of an increased risk of developing CVD in relation to their RA, and this frequently occurred in those with a greater number of traditional CVD risk factors. Misperceptions about CVD were common, and the majority of subjects misestimated their actual CVD risk. Conclusion Individuals with RA at highest risk for CVD report low awareness and perceived risk of this comorbidity. This represents a knowledge gap in need of intervention but must be tailored to patients’ needs. An understanding of the system- and individual-level barriers preventing CVD awareness is needed. Only then will approaches to improve CVD screening and management in RA be successful.
