Cardiology co-management of rheumatoid arthritis patients with coronary artery disease as an intervention reduces hospitalization rates and adverse event occurrence

INTRODUCTION: Rheumatoid arthritis (RA) is a systemic autoimmune disease with important cardiovascular (CV) implications. CV disease represents over half of RA patient deaths and causes significant morbidity. CV manifestations in RA can be complex, raising concerns for adequate patient management and provider-dependent roles. METHODS: This is a retrospective study of patients diagnosed with RA and coronary artery disease (CAD). Patients were identified and filtered via EPIC Database search engine. Parameters were set from January 1, 2014, to December 31, 2020. Inclusion criteria consisted of patients who met diagnostic criteria for both RA and CAD. A total of 399 patients met criteria. RESULTS: Of the 399 identified patients, 272 were female (68.2%) and 127 were male (31.8%) with a median age of 73 (range 26–98). The population was further divided into two groups: those with established cardiology care versus those without. Patients without cardiology follow-up experienced significantly more hospitalizations (RR 1.63 95% CI 1.12, 2.38), higher rates of adverse events including myocardial infarction (MI) (RR 4.82 95% CI 1.94, 11.98), heart failure (HF) (OR 15.81 95% CI 3.54, 70.52), and stroke (RR 2.55 95% CI 1.29, 5.03). Patients not followed by cardiology also had numerical increases in CV death (4 deaths compared to none in those with cardiology follow) and all-cause mortality (HR 1.03 95% CI 0.63, 1.67). CONCLUSION: Patients with regular cardiology follow-up demonstrated fewer cardiac-related adverse events. This suggests that co-management may have a role in adverse cardiac event risk reduction and should therefore be an early consideration.
