Insights
Patients with rheumatoid arthritis (RA) have a significantly increased risk of cardiovascular disease (CVD), comparable to that of type 2 diabetes (DM2). This finding highlights the need for enhanced cardiovascular prevention strategies in RA patients.
Area of Science:
- Rheumatology
- Cardiology
- Endocrinology
Background:
- Rheumatoid arthritis (RA) is associated with increased cardiovascular risk.
- The precise magnitude of this risk compared to type 2 diabetes (DM2) is not well-defined.
Purpose of the Study:
- To investigate the association between RA and cardiovascular disease (CVD).
- To compare the CVD risk in RA patients with that in type 2 diabetes (DM2) patients.
Main Methods:
- Cross-sectional study comparing RA outpatients (CARRE study) with participants from a diabetes and CVD cohort (Hoorn study).
- Prevalence of CVD (coronary, cerebral, peripheral arterial disease) assessed in RA patients without diabetes, DM2 patients, and non-diabetic individuals.
Main Results:
- CVD prevalence was 12.9% in RA patients and 12.4% in DM2 patients, compared to 5.0% in non-diabetic individuals.
- Age- and gender-adjusted odds ratio for CVD was 3.1 in RA and 2.3 in DM2, relative to non-diabetic individuals.
- These associations persisted after adjusting for conventional cardiovascular risk factors.
Conclusions:
- Cardiovascular disease prevalence in RA is significantly elevated, comparable to that observed in type 2 diabetes.
- These findings underscore the importance of implementing proactive cardiovascular prevention strategies for individuals with RA.
Objectives:
Patients with rheumatoid arthritis (RA) have an increased cardiovascular risk, but the magnitude of this risk is not known precisely. A study was undertaken to investigate the associations between RA and type 2 diabetes (DM2), a well-established cardiovascular risk factor, on the one hand, and cardiovascular disease (CVD) on the other.
Methods:
The prevalence of CVD (coronary, cerebral and peripheral arterial disease) was determined in 353 randomly selected outpatients with RA (diagnosed between 1989 and 2001, aged 50-75 years; the CARRE study) and in participants of a population-based cohort study on diabetes and CVD (the Hoorn study). Patients with RA with normal fasting glucose levels from the CARRE study (RA, n = 294) were compared with individuals from the Hoorn study with normal glucose metabolism (non-diabetic, n = 258) and individuals with DM2 (DM2, n = 194).
Results:
The prevalence of CVD was 5.0% (95% CI 2.3% to 7.7%) in the non-diabetic group, 12.4% (95% CI 7.5% to 17.3%) in the DM2 group and 12.9% (95% CI 8.8% to 17.0%) in those with RA. With non-diabetic individuals as the reference category, the age- and gender-adjusted prevalence odds ratio (OR) for CVD was 2.3 (95% CI 1.1 to 4.7) for individuals with DM2 and 3.1 (95% CI 1.6 to 6.1) for those with RA. There was an attenuation of the prevalences after adjustment for conventional cardiovascular risk factors (OR 2.0 (95% CI 0.9 to 4.5) and 2.7 (95% CI 1.2 to 5.9), respectively).
Conclusions:
The prevalence of CVD in RA is increased to an extent that is at least comparable to that of DM2. This should have implications for primary cardiovascular prevention strategies in RA.
