[Composition and physical structure of atherogenic lipoproteins in ischemic heart disease]. / Osobennosti sostava i fizicheskoi struktury aterogennykh lipoproteinov pri ishemicheskoi bolezni serdtsa.

The results of comparative studies in atherogenic lipoproteins of blood plasma under heart ischemic disease (HID) which is accompanied by hypercholesterinemia or proceeds without disturbances in the lipid metabolism, evidence for considerable differences in the composition and physical structure of very low-density lipoproteins (VIDL) and low-density ones (LDP) under the investigated states. The decrease in the surface charge density and in sizes of VLDL, as compared to normal, which are least expressed at HID and an increase in the surface charge density with certain increase of LDL radii under this pathologic state are revealed.
