Atherosclerosis: the eicosanoid connection.

This bird's eye view presents connections between the metabolically short-lived local hormones (collectively known as eicosanoids) and atherosclerotic cardiovascular disease. The discussion will be centered around an overview of coronary atherosclerosis with an emphasis on the sequences involved in the formation of atherosclerotic lesions; structure and historical background of oxygenated fatty acids cyclooxygenase and lipoxygenase products--eicosanoids; the generation of free radicals during the formation of endoperoxides by cyclooxygenase; the involvement of eicosanoids in the atherosclerotic inflammatory process, and finally, the effects of non-steroidal and steroidal anti-inflammatory drugs on the synthesis of eicosanoids and experimental atherosclerosis. Little is known about the exact role of eicosanoids in the genesis of atherosclerosis.
