Abstract:
A great deal of progress has been made in the past few years in our understanding of the processes involved in atherogenesis and in mechanisms by which commonly accepted risk factors may affect these processes. These insights have allowed us to understand how various interventions may retard atherogenesis and decrease clinical events by improving plaque stability. The identification of new risk factors, such as lipoprotein(a), and of particular molecules that can be identified in atherosclerotic tissue, such as adhesion molecules, growth factors, cytokines, and proteins that regulate cholesterol uptake and removal, have identified several potential new targets for therapeutic intervention. Advances in molecular biologic techniques, including transgenic techniques, have markedly increased the types of potential interventions available. A major challenge for the future will be to determine which among this plethora of therapeutic possibilities holds the most promise for decreasing the morbidity and mortality associated with this disease.
