The small-sized plasma oxidized (ox) low-density lipoprotein (LDL) particles in dense LDL may make them more atherogenic than ox-LDL particles in less-dense LDL.
The distribution of, and the statin effects, ox-LDL in LDL fractions has not been studied in detail.
The distributions of cholesterol and ox-LDL in, and the rosuvastatin effects, LDL fractions were studied.
The distribution of ox-LDL was skewed more toward the denser LDL fractions, compared with cholesterol; rosuvastatin reduced both ox-LDL and cholesterol in all LDL fractions.
