Atherosclerotic vascular disease in the autoimmune rheumatologic patient.

Autoimmune diseases, such as rheumatoid arthritis and systemic lupus erythematosus, have a strong association with an increased risk of atherosclerotic cardiovascular diseases (ASCVD), particularly ischemic heart disease (IHD). A majority of the autoimmune conditions occur predominantly in women, and as women continue to experience a higher cardiovascular mortality compared to men, this potential added risk factor must be recognized. Inflammation and immune mechanisms have been shown to be an underlying mechanism for the development of atherosclerosis, thus sharing a common mechanism with rheumatologic conditions. There is an under recognition, in both patient and physician, of the increased cardiovascular (CV) risk within the autoimmune population, with present CV risk profile algorithms performing poorly in these patients. Traditional risk factors play a role in the development of IHD in the autoimmune patient, but their overall significance is unclear and does not fully explain the elevated CV risk. The role of inflammation and risk factors in autoimmune conditions, and their link to the elevated CV risk will be explored within this article.
