Insights
Diabetic rheumatoid arthritis (RA) patients show higher rates of preclinical atherosclerosis compared to non-diabetic RA patients. Combined carotid and femoral ultrasonography did not enhance atherosclerosis detection in RA patients.
Area of Science:
- Cardiovascular Medicine
- Rheumatology
- Endocrinology
Background:
- Rheumatoid arthritis (RA) is associated with an increased risk of cardiovascular disease.
- Diabetes mellitus further elevates cardiovascular risk.
- The interplay between diabetes, RA, and subclinical atherosclerosis requires further investigation.
Purpose of the Study:
- To compare the prevalence of preclinical atherosclerosis in diabetic versus non-diabetic RA patients.
- To identify factors influencing atherosclerosis in RA.
- To evaluate the utility of combined carotid and femoral ultrasonography for atherosclerosis detection.
Main Methods:
- A cross-sectional study involving 42 non-diabetic RA patients, 42 diabetic RA patients, and 42 controls.
- Measurement of intima-media thickness (IMT) in carotid and femoral arteries.
- Screening for atherosclerotic plaque in these vessels.
Main Results:
- Diabetic RA patients exhibited a higher prevalence of atherosclerotic plaque compared to non-diabetic RA patients and controls.
- Elevated carotid and femoral IMT were observed in diabetic RA patients versus controls.
- Femoral IMT was also higher in diabetic RA patients compared to non-diabetic RA patients.
- Carotid ultrasonography alone demonstrated comparable efficacy to combined carotid and femoral ultrasonography in detecting atherosclerosis.
Conclusions:
- Diabetic RA patients have a greater burden of subclinical atherosclerosis.
- Combined carotid and femoral artery ultrasonography does not offer improved detection of atherosclerosis in RA patients compared to carotid ultrasonography alone.
Objectives:
(1) To compare the prevalence of preclinical atherosclerosis in diabetic vs. non-diabetic rheumatoid arthritis (RA) patients; (2) to determine the influence of classical and RA-related factors on atherosclerosis; (3) to assess the usefulness of combined carotid and femoral ultrasonography in detecting atherosclerosis.
Methods:
The study comprised 42 non-diabetic RA patients, 42 diabetic RA patients and 42 controls. Intima media thickness (IMT) was measured in the common carotid and superficial femoral arteries. These vessels were screened for atherosclerotic plaque.
Results:
Plaque was more prevalent in diabetic RA patients than in non-diabetic RA patients or controls. Carotid IMT and femoral IMT were higher in diabetic RA patients compared to controls. So was femoral IMT in diabetic compared to non-diabetic RA patients. The prevalence of increased IMT and plaque was comparable in carotid ultrasonography and combined carotid and femoral ultrasonography in all groups.
Conclusions:
Subclinical atherosclerosis was found to be higher in diabetic RA patients than in non-diabetic RA patients. The combination of carotid and femoral artery ultrasonography did not improve the detection of atherosclerosis in RA.
