Serum lipids act as inverse acute phase reactants and are falsely low in @entity1 with XXXX .

@entity1 @entity63 @entity583 @entity165 @entity1851
BACKGROUND: Lipid levels generally fall after an acute @entity583 . This study was conducted to see what trends lipid levels had in @entity1 who underwent operation for @entity63 . METHODS: The study was prospective and included 30 @entity1 who underwent operation for @entity63 . Serum lipid profiles and @entity1851 were analyzed before surgery and 3 months after peripheral bypass surgery. In addition, comparison of lipid levels after surgery was made with 287 healthy and 283 @entity63 heart disease controls from The Copenhagen City Heart Study. RESULTS: Total, low density lipoprotein, and high density lipoprotein @entity165 levels were found to be significantly lower before surgery than 3 months after surgery (P <.001). In contrast, @entity1851 was higher before surgery and decreased after 3 months (P <.0001). An inverse linear correlation was found between total @entity165 /low density lipoprotein @entity165 and @entity1851 (P <.001 and P <.04, respectively). Comparison with controls showed that @entity165 levels 3 months after surgery were significantly lower (P <.009). CONCLUSION: Serum @entity165 levels are not reliable in the preoperative period and should therefore be measured at least 3 months after surgery when they seem to approach a more representative level.
