Cardiac involvement in systemic lupus erythematosus(SLE) is common and has been reported in more than 50% of the patients at the same stage during their illness. SLE can affect the heart in a number of ways;myocarditis, pericarditis, aortic insufficiency, hypertensive heart disease, and coronary arteritis. In recent years, with prolonged survival and improvement in diagnostic modalities, the cardiovascular manifestations of SLE have become more apparent. Coronary artery disease has a number of possible pathogenic mechanisms;atherosclerosis, coronary arteritis, spasm, and hypercoagulability. For management purposes, differentiation between arteritis and artheroslerosis is important. Atherosclerosis in the coronary as well as other vessels appears to be accelerated by SLE. Cardiovascular care to the SLE patients should be emphasized, because corticosteroid treatment and auto-immune mechanisms of SLE are able to promote the atherosclerosis of coronary arteries.
