The role of infection in the pathogenesis of cardiovascular disease.
Atherosclerosis is a complex, multifactorial disease. Recently, research has intensified to identify the role of various infections in the pathogenesis of atherosclerosis. Specific agents have been proposed as direct initiators or accelerators of atherosclerosis, while other infectious agents have been proposed as accelerators of atherosclerosis through nonspecific stimulation of the inflammatory cascade. Recently, the total pathogen burden concept has suggested that while each specific infection contributes only slightly to the pathogenesis of atherosclerosis, the cumulative effects of infectious agents contribute greatly. Several randomized trials evaluating antibiotic therapy in the prevention of cardiovascular events have now been completed, although results have been conflicting. This manuscript summarizes current understanding of the role of infectious agents as a trigger of inflammation, as a contributor to atherosclerosis, and the potential role of antibiotic therapy in the treatment of atherosclerosis.
