Cardiovascular
Disease in a Large Incident Cohort of Early Inflammatory Arthritis
Background/Purpose:
Rheumatoid Arthritis (RA) is associated with an increased risk of
cardiovascular disease (CVD). The aim of this study is to determine the
incidence and predictors of CVD in Early Inflammatory Arthritis (EIA) from the
Canadian early arthritis cohort (CATCH).
Methods: CATCH
is a multicentre, prospective inception cohort of patients with EIA. Cardiovascular
disease (CVD) was defined as an acute coronary syndrome, percutaneous or
surgical intervention for coronary artery disease, stroke, transient ischemic
attack, peripheral vascular disease requiring surgical intervention or death
secondary to CVD. Pre-existing diagnoses of CVD, risk factors and medications
for CVD were collected at baseline by physician. Incident CVD events and
cardiac medications after study enrollment were self-reported by patients. Stepwise
logistic regression was used to identify predictors for CVD.
Results:
2652 patients were enrolled in the study with a mean follow-up of 3.4 (SD 2.1)
years. At baseline, 180 (7%) had pre-existing CVD. During the course of
follow-up there were 62 new CVD events in 57 subjects. There were a total of 6 deaths (1 secondary
to CVD). The incidence rate of CVD for years 1, 2, 3, 4 and 5 of the study, respectively
were: 2.3, 4.4, 15.4, 10.4, 10.8 per 1000 person-years. Patients with new CVD
events were older, more likely male and have higher rates of traditional CVD
risk factors (Table 1). Arthritis-related factors were not significantly
associated with the risk of CVD. Independent predictors of CVD were male gender
(OR 1.8 (95% CI: 1.0-3.0), dyslipidemia (OR 1.8 (95% CI: 1.1-3.2)), hypertension
(OR 2.7 (95% CI: 1.6-4.6)) and the use of non-steroidal anti-inflammatories (NSAIDs)
(OR 3.2 (95% CI: 1.8-5.6). Less than 25% of subjects with a CVD diagnosis
reported taking aspirin or cholesterol-lowering drugs during the follow-up
period.
Conclusion:
The rate of CVD events in patients
with EIA was higher later in the disease course. CVD appears to be
under-treated and is independently associated with traditional CVD risk factors
and the use of NSAIDs.
