[Electrostatic potential on the surface of low density lipoproteins from the plasma of patients with ischemic heart disease: estimation using a fluorescent probe].

Fluorescent probe I-aniline-8-naphthalene sulfonate was used to evaluate the LDL surface potential values in patients with coronary artery atherosclerosis. The more negative charge was found on the LDL surface in patients with atherosclerosis of three coronary arteries as compared with that of healthy persons.
