Abstract

Background Cardiovascular (CVD) comorbidity and mortality in rheumatoid arthritis (RA), is well documented.1 Increased prevalence of the metabolic syndrome, higher disease activity, greater prednisone and less DMARD usage are established contributors. RA patients are less frequently evaluated for CVD risk factors2. Yet, ethnic minorities have a greater prevalence of CVD risk factors and events.

Objectives To evaluate the CVD risk scores in ethnic minority RA patients.

Methods Enrolled, consented EMRAC patients were evaluated. Data collected include socio-demographic, RA disease severity and activity-related parameters, tobacco use, prednisone and DMARD/biologic usage, and comorbidities (HTN, DM, lipidemia, CVD event). Additional data included systolic BP, total cholesterol (TC), LDL, HDL. Coronary heart disease (CHD) and non-coronary cardiovascular disease (CVD) 10-year risk SCORES3 were calculated for ethnic minority subsets, and association with RA disease-related variables and treatments evaluated. CHD and CVD 10 yr-risk scores were sumarrized as continuous and dichotomozied at >5%.

Results 156 EMRAC patients had complete datasets for analysis. The majority were female, 142(91%), of mean age 58.1 (13.6) years, with mean disease duration 8.9 (7.8) years. 70 (45%) were Caucasian, 20 (13%) were African-American, 26 (17%) were Hispanic with 40 (26%) Other. Mean values for lipids were as follows: HDL, 64.9 (17.1) mg/dl, LDL 104(33.5) mg/dl and TC 191(39.0) mg/dl. Mean Systolic BP was 124.4(16.5) mmHg. CVD risk is summarized in Table. Dichotomizing the predicted risk score at 5%, our cohort’s fatal CVD risk ranged from 14% (low risk profile) to 20% (high risk profile). However, 25% of the African-Americans had a 5% risk (low and high risk profiles) compared to Caucasians risk which ranged from 9% to 17% (low risk and high risk profile, respectively), but did not reach statistical signficance.

Conclusions EMRAC patients are at risk for fatal CVD events. While the limited sample size precluded statistical significance in ethnic differences, there is the potential for clinical relevance and our findings call for due diligence in minimizing CVD risk factors.
