BACKGROUND: Cardiovascular disease (CVD) is the leading cause of death in
rheumatoid arthritis (RA) patients. This study is the first to report the
association of hydroxychloroquine (an antirheumatic medication that has been
associated with decreased risk of diabetes, a less atherogenic lipid profile, and
antithrombotic properties) with CVD in RA. METHODS AND RESULTS: A retrospective
incident RA cohort from January 1, 2001, to October 31, 2013, excluding patients
with CVD prior to RA diagnosis, was constructed. Patients were categorized as
hydroxychloroquine users versus nonusers and were allowed to contribute time to
either group according to hydroxychloroquine exposure. The primary outcome was
adjudicated incident CVD defined as a composite of coronary artery disease,
stroke, transient ischemic attack, sudden cardiac death, and peripheral artery
disease with arterial revascularization procedure. The secondary outcome was a
composite of incident coronary artery disease, stroke, and transient ischemic
attack. Cox time-varying regression models were used to estimate the association
between hydroxychloroquine exposure and development of CVD, after adjusting for
propensity score and relevant confounders, including demographics, CVD-related
comorbidities, RA severity, and activity indicators and medications. We included
1266 RA patients, 547 hydroxychloroquine users, and 719 nonusers. During the
observation period, 102 CVD events occurred, 3 in hydroxychloroquine users and 99
in nonusers. The fully adjusted Cox model showed a hazard ratio of 0.28 (95% CI
0.12-0.63, P=0.002) for incident CVD and 0.30 (95% CI 0.13-0.68, P=0.004) for
incident composite coronary artery disease, stroke, and transient ischemic attack
for hydroxychloroquine users versus nonusers, respectively. CONCLUSION: In this
hypothesis-generating study, hydroxychloroquine use was associated with a 72%
decrease in the risk of incident CVD in RA patients. If these preliminary results
are confirmed in larger studies, our findings may be used as a rationale for a
randomized study of hydroxychloroquine use for primary prevention of CVD in RA or
nonrheumatic high-risk patients.
