초록
NonHDL cholesterol values have been suggested as a risk marker for cardiovascular disease. NonHDL cholesterol values were calculated, using a very simple measurement [nonHDL cholesterol =serum total cholesterol-HDL cholesterol]. This formula is very useful as a screening tool for identifying dyslipoproteinemias, risk assessment, and assessing the results of hypolipidemic therapy. The data from the 2009 Korean National Health and Nutrition Examination Survey were used. Analysis was done for 1,992 subjects with lipid panels (Cholesterol, HDL, LDLdirect and Triglycerides) results. We studied the relationship between nonHDL cholesterol and LDL cholesterol. As a result, nonHDL cholesterol values were plotted against the LDL direct and calculated values. The linear regression equation for nonHDL cholesterol and direct LDL cholesterol was nonHDLchol=23.60+1.03×LDLdirect (p＜0.0001, r2=0.80) in all subjects. The subjects were classified into triglyceride values. When triglycerides are below 400 mg/dL, the linear fit to LDL direct is found to be [nonHDLchol=17.34+1.07×LDLdirect] (p＜0.0001, r2=0.88) and to the Friedewald LDL calculation is [nonHDLchol=23.10+1.02×LDLcalc] (p＜0.0001, r2=0.82). For triglycerides above 400 mg/dL, the linear fit equation is [nonHDLchol=87.57+0.92×LDLdirect] (p ＜0.0001, r2=0.50) and to the LDL calculated, it is [nonHDLchol=142.70+0.50×LDLcalc] (p ＜0.0001, r2=0.32). This study provides examples of the utility of nonHDL cholesterol concentrations in clinical medicine.
Abstract
NonHDL cholesterol values have been suggested as a risk marker for cardiovascular disease. NonHDL cholesterol values were calculated, using a very simple measurement [nonHDL cholesterol =serum total cholesterol-HDL cholesterol]. This formula is very useful as a screening tool for identifying dyslipoproteinemias, risk assessment, and assessing the results of hypolipidemic therapy. The data from the 2009 Korean National Health and Nutrition Examination Survey were used. Analysis was done for 1,992 subjects with lipid panels (Cholesterol, HDL, LDLdirect and Triglycerides) results. We studied the relationship between nonHDL cholesterol and LDL cholesterol. As a result, nonHDL cholesterol values were plotted against the LDL direct and calculated values. The linear regression equation for nonHDL cholesterol and direct LDL cholesterol was nonHDLchol=23.60+1.03×LDLdirect (p＜0.0001, r2=0.80) in all subjects. The subjects were classified into triglyceride values. When triglycerides are below 400 mg/dL, the linear fit to LDL direct is found to be [nonHDLchol=17.34+1.07×LDLdirect] (p＜0.0001, r2=0.88) and to the Friedewald LDL calculation is [nonHDLchol=23.10+1.02×LDLcalc] (p＜0.0001, r2=0.82). For triglycerides above 400 mg/dL, the linear fit equation is [nonHDLchol=87.57+0.92×LDLdirect] (p ＜0.0001, r2=0.50) and to the LDL calculated, it is [nonHDLchol=142.70+0.50×LDLcalc] (p ＜0.0001, r2=0.32). This study provides examples of the utility of nonHDL cholesterol concentrations in clinical medicine.
