THE EFFECT OF THE AMERICAN HEART ASSOCIATION STEP ONE DIET ON HYPERLIPIDEMIA FOLLOWING RENAL TRANSPLANTATION

Abstract

Cardiovascular disease is a frequent cause of morbidity and mortality following renal transplantation. The percentage of deaths due to ischemic cardiovascular disease and cerebrovascular accidents nearly equals that caused by infection among patients receiving their first transplant, according to data from the European Dialysis and Transplant Association Registry. Hypercholesterolemia is a risk factor for cardiovascular disease frequently identified following renal transplantation, and diets low in fat and cholesterol have been suggested as treatment. Previous studies have not reported the response of LDL cholesterol to dietary treatment, and it is this form of cholesterol that is most closely related to cardiovascular disease. The American Heart Association has provided nutritionists with guidelines for the treatment of hyperlipidemic patients which include the Step One Diet. Previous dietary studies of renal transplant recipients have allowed a slightly higher intake of fat than that currently recommended by the AHA. We wondered if an easily reproducible diet well known to nutritionists such as the AHA Step One Diet would be effective in lowering cholesterol levels in hyperlipidemic renal transplant recipients. The purpose of our study was not to define the mechanisms of posttransplant hyperlipidemia, but rather to assess the effectiveness of dietary intervention on hyperlipidemia following renal transplantation.
