The possible role of infectious and inflammatory states in the pathogenesis of atherosclerotic disease has been a matter of debate in the literature. There are case reports of active cytomegalovirus (CMV) infection unmasking underlying dormant systemic lupus erythematosus (SLE). CMV infection has also been postulated to be associated with atherosclerosis development in the coronaries. We present a unique case where a patient with newly diagnosed SLE and acute myocardial infarction was found to have high anti-CMV titers suggesting concomitant active CMV infection. A literature review has postulated strong affiliation of CMV infection with the development of coronary artery disease, an avenue which has yet to be explored further by ongoing research.
