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...

In most clinical laboratories, low density lipoprotein (LDL) cholesterol is usually estimated indirectly with the Friedewald equation or directly with the N-geneous assay. We assessed LDL-cholesterol values obtained by both methods to find an appropriate fasting period and to assess the influence of the energy content of the last meal. Blood samples were taken from 28 healthy volunteers who had...

We compared low-density lipoprotein cholesterol (LDL) values obtained by the Friedewald formula--i.e., total cholesterol minus high-density lipoprotein (HDL) cholesterol minus very-low-density lipoprotein (VLDL) cholesterol (estimated as triglyceride divided by 5)--with those obtained by lipoprotein fractionation, using 4736 specimens. When triglycerides were less than 2.0 g/L, greater than 90%...

Low-density lipoprotein cholesterol (LDL-C) is frequently estimated using the empirical Friedewald equation. We compared the accuracy of the novel equation named as the 180-cell method (180-c), which estimates LDL-C using a stratification approach, to those of 9 previously suggested formulas, including the Friedewald equation.We compared the accuracy of 10 equations by calculating intraclass co...

Bevezetés: Az akut koronáriaszindrómán (ACS) átesett betegek a kardiológia nagy létszámú és egyik legvulnerábilisabb betegcsoportja, akik lipidértékeinek kezelésére minél nagyobb kockázat, annál az elérhető nyereség elv alapján nagyon oda kellene figyelnünk. Célkitűzés: Annak vizsgálata, hogy miként alakultak invazív centrumként működő megyei kórházban COVID-időszak egy éve alatt ACS miatt keze...

Background: Small dense low-density lipoprotein concentration (sdLDLC) subclasses are smaller in volume than other LDL types, they have a greater propensity for endothelial penetration and subsequent atherogenesis. The objectives of the study assessed relationship between sdLDLC cardiovascular risk obesity Method: This cross-sectional was conducted on obesity. Informed written consent obtained ...
