Abstract
OBJECTIVE
To evaluate the predictive role of time-averaged disease activity score (DAS)28 and Health Assessment Questionnaire (HAQ) on cardiovascular disease (CVD) events in patients with rheumatoid arthritis (RA).
METHODS
Patients with RA were recruited from 23 tertiary hospitals. Baseline and annual follow-up data of demographic, laboratory, questionnaire, RA-associated parameters, and occurrence of CVD were collected. Patients were divided into three groups according to time-averaged DAS28: 1) remission (<2.6), 2) low (2.6-3.2), 3) moderate (3.2-5.1), and 4) high (>5.1). Kaplan-Meier curves was performed to compare the cumulative probability of CVD. Hazard ratios of each factor on the occurrence of CVD were obtained using Cox regression analyses.
RESULTS
A total of 4,034 RA patients with 826 for remission, 938 for low, 2,002 for moderate, and 268 for high time-averaged DAS28 groups were included. Baseline age, disease duration, ESR, CRP, DAS28, and HAQ scores were higher in the high time-averaged DAS28 group. The incidence rate of CVD was 2.86, 2.71, 3.53, and 8.13 events per 1,000 person-years for the remission, low, moderate, and high time-averaged DAS28 groups, respectively. The incidence rate ratio of CVD in the high time-averaged DAS28 group were 3.01 (95% CI 1.20-8.50) when compared to low time-averaged DAS28 group. The cumulative hazard for CVD in the high time-averaged DAS28 group was significantly high (log-rank P<0.01). In multivariate Cox regression analysis, age, high time-averaged DAS28, and time-averaged HAQ>0.5, were positively associated with CVD events in RA patients.
CONCLUSIONS
In patients with RA, time-averaged DAS28 and HAQ could predict the occurrence of CVD.
