Inaccuracy of serum lipid measurements after open heart operations.
Serum lipids were measured in 20 patients before and within one week following coronary artery bypass. The total serum cholesterol was decreased by 45%, while low density lipoprotein cholesterol and high density lipoprotein cholesterol were reduced by 50% and 30%, respectively. Hemodilution for cardiopulmonary bypass temporarily lowers serum lipids, indicating that screening procedures for hyperlipidemia should not be performed immediately following cardiac operations.
