Abstract
-
BACKGROUND/AIMS: Statins have been a mainstay of treatment for primary and secondary prevention of coronary heart disease through their beneficial effect on lipid profile. However, their effect on the HDL cholesterol level has been determined to be equivocal or unclear. This study sought to investigate HDL cholesterol response to statin treatment in type 2 diabetic patients.
METHODS
We retrospectively assessed the effect of statins in 217 patients with type 2 diabetes and dyslipidemia through chart review. Patients who were using medications such as fibrates, niacin, or thiazolidinediones, or had a plasma creatinine concentration greater than 1.5 mg/dL, a fasting triglyceride level greater than 300 mg/dL, or chronic liver disease, were excluded from the study. RESULT: The mean level of LDL cholesterol was significantly decreased, and the percentage of patients who achieved the normal LDL cholesterol level was increased in this study. The mean HDL cholesterol level after statin treatment was decreased by 2.3%. The percent change of HDL cholesterol was affected by baseline HDL cholesterol level, percent change of total cholesterol, percent change of LDL cholesterol, and baseline total cholesterol level. When subjects were divided into quintiles according to baseline HDL cholesterol, HDL cholesterol level was found to be increased in the lowest two quintiles while it was decreased in the highest two quintiles.
CONCLUSIONS
There were some patients whose HDL cholesterol level was decreased after statin treatment, depending on their baseline HDL cholesterol level. We think further study on the effect of statins on HDL level will be needed in the future.
