Rheumatoid arthritis may double heart attack risk
Washington, July 30 (ANI): Patients with rheumatoid arthritis are twice as likely to suffer a heart attack, suggests a new study.

Although it's not clear how these conditions are linked to cardiovascular disease, it believed that it might be a result of inflammation.
In people with rheumatoid arthritis and lupus inflammation turns against the body and damages joints and other tissues.
In heart disease, inflammation kicks off artery-clogging atherosclerosis, keeps it smouldering, and influences the formation of clots, the main cause of heart attacks and strokes.
The study suggests that controlling rheumatoid arthritis or lupus with medications used for treating inflammation may help in reducing the excess risk of heart disease.
The study appears in the August 2008 issue of the Harvard Heart Letter. (ANI)
