Opis

Major advances have been made in the understanding of the molecular mechanisms of atherosclerosis, the disease that still affects more than 50 percent of the population in the highly industrialized countries. This volume covers the most recent advances in the treatment of hyperlipidemia. It represents a necessary update because molecular mechanisms of atherogenesis have been discovered in the past few years and their molecular mechanisms of action identified. Extensively treated are the molecular mechanisms of disease etiology of arteriosclerosis in relation to the major risk factor "hyperlipidemia," rationale for more effective treatment of this disease by dietary means, the treatment of associated or causing diseases, and the treatment using hypolipidemic drugs.
