The effect of age on plasma lipids, platelet fatty acids and prostacyclin release was studied in the rat. The contents of arachidonic acid, cholesterol, bile acids and free fatty acids in the plasma of aged rats (15 months old) were higher than those of young rats (3 months old). No significant differences in fatty acid composition of platelet lipids and release of prostacyclin from aortas between young and aged rats were observed. The data suggest that plasma lipids may play a more important role in the development of cardiovascular disease with increasing age than prostaglandins do.
