Accelerated atherosclerosis in systemic lupus erythematosus and other connective tissue diseases

Abstract

Connective tissue diseases are associated with increased morbidity and mortality related to a higher rate of cardiovascular events and higher prevalence of subclinical atherosclerosis. Atherosclerosis is now considered a multifactorial process where autoimmunity and chronic inflammation play an important pathogenic role. In systemic autoimmune rheumatic diseases in general, and in systemic lupus erythematosus in particular, atherosclerosis cannot be explained by traditional cardiovascular risk factors alone. Cellular and humoral mechanisms, together with specific factors associated with the disease itself and/or its treatments, have been advocated to explain the acceleration of arterial wall organic damage in these patients. Endothelial dysfunction, carotid intima-media thickness and plaque evaluations provide accurate detection of atherosclerotic process at a preclinical stage, before appearance of clinical disease, allowing preventive measure introduction with the aim to modify the cardiovascular risk in subjects with systemic autoimmune rheumatic diseases.
