Comparison of LDL cholesterol concentrations by Friedewald calculation and direct measurement in relation to cardiovascular events in 27,331 women.
BACKGROUND National Cholesterol Education Program (NCEP) guidelines recommend development of direct assays for LDL cholesterol (LDL-C) measurement, but it is unclear how these assays compare with Friedewald calculation in predicting cardiovascular disease (CVD). METHODS In a study of 27 331 healthy women with triglycerides <or=4.52 mmol/L (<or=400 mg/dL), baseline fasting Friedewald LDL-C was...

15 صفحه اولComparison of LDL-cholesterol direct measurement with the estimate using the Friedewald formula in a sample of 10,664 patients.
OBJECTIVE To compare direct measurement of LDL-cholesterol (LDL-C) determined by a homogeneous method with LDL-cholesterol estimation determined by the Friedewald formula in a large heterogeneous population. METHODS The measurements of total cholesterol (TC) and triglycerides (TG) were performed using traditional enzymatic methods. The measurements of HDL-C and LDL-C were performed using dire...

able amounts of radiolabeled dextran in the plasma protein fraction [15]. Consequently, we do not think this mechanism plays a substantial role in producing the lower than expected dextran concentrations seen in the present study. The dextran we used had a mean molecular mass of 70 000 Da. Thus, some quantity of lower-molecular-mass dextran could have leaked out of the vascular space and distri...
متن کاملMeasuring Low Density Lipoprotein Cholesterol: Comparison of Direct Measurement by HiSens Reagents and Friedewald Estimation
BACKGROUND Directly measured low density lipoprotein cholesterol (DLDLC) has been reported to be more accurate than calculated low density lipoprotein cholesterol (CLDLC) using the Friedewald equation. However, some limitations of DLDLC have been reported. In this study, we evaluated differences between CLDLC and DLDLC measured using HiSens reagents. METHODS Data were collected from 582 perso...
