Abstract

BACKGROUND & OBJECTIVES: Patients with Rheumatoid Arthritis (R.A.) have a marked increase in Carotid Atherosclerosis independent of traditional risk factors like family history of myocardial infarction in first degree male relatives younger than 55 years of age or first degree female relatives younger than 65 years of age, smoking, hypertension (Defined as blood pressure of 140/90 mm hg or higher), diabetes mellitus and fasting serum cholesterol levels including age. Chronic inflammation and possibly disease severity and duration are atherogenic in Rheumatoid Arthritis patients. Preclinical disease may also be identified by using ultrasonography to determine carotid intimal-media thickness, an indirect measure of atherosclerosis. The common carotid artery Intima media thickness in Rheumatoid Arthritis patients is positively associated with disease duration, Early Rheumatoid Arthritis (Duration less or = 1 year) is associated with lesser Intima media thickness than was Rheumatoid Arthritis of longer duration. Increased carotid artery Intima media thickness and the presence of carotid plaque are associated with markers of systemic inflammation in patients with Rheumatoid Arthritis and in healthy subjects. OBJECTIVE OF THE STUDY: To determine preclinical atherosclerosis occurring prematurely in patients of Rheumatoid Arthritis by ultrasonograhic measurement Common Carotid Artery Intima media thickness and to evaluate the risk factors associated with arterial intima media thickness in patient of Rheumatoid Arthritis. RESULTS: In RA patients, common carotid artery IMT was significantly higher when compared to healthy controls (0.65 ± 0.06 v/s 0.57 ± 0.049) and was significantly associated with the duration of RA, swollen joint count and erosive changes on hand x-ray independently of other confounding variables. CONCLUSION: Patients with rheumatoid arthritis have a marked increase in carotid atherosclerosis independent of traditional risk factors, including age. Carotid ultrasonography is a simple and inexpensive way of identifying preclinical atherosclerosis in this highly vulnerable population. In addition to prospective management of traditional risk factors, there is a need for aggressive control of rheumatoid arthritis disease activity because chronic inflammation is a driving force for premature atherosclerosis.
