[Infection and atherosclerosis].

Atherosclerosis is a chronic inflammation and the cause of most cardiovascular diseases. It is the main cause of death in the Western world today, even though growing incidence of atherosclerosis-related diseases has been recently observed in developing countries, too. In many patients with atherosclerosis, however, traditional risk factors for atherosclerosis are not identifiable. This has renewed the interest, in recent years, in the links between atherosclerosis and environmental exposures, including infectious agents. Infection was identified as as risk factor for atherosclerosis in the first half of the 20th century. Experimental and clinical studies have shown that infection can stimulate atherogenic processes and that there are significant interactions between infection and traditional risk factors. Yet there are questions concerning etiology, pathogenesis and appropriate interventions which remain unanswered. The following article provides an overview of the role of the infectious agents in atherosclerosis and discusses possible intervention strategies.
