The impact of food fat load on plasmic lipid transport system (LTS) was studied in persons with abdominal and gluteofemoral obesity by the standard fat test proposed by J. Patsch. The lipoprotein spectrum in abdominally obese patients was characterized by high atherogenicity of lipoprotein spectrum on an empty stomach aggravating under fat intake: prolongation of postprandial lipemia up to 6 hours with growing apoB and apoB/A1. Patients with gluteofemoral obesity differed from normal weight persons only by higher fasting values of triglycerides. They showed no atherogenic trend in changes in response to food fat.

Effects of fatty loading on patterns of the lipoprotein system were studied in blood plasma of 39 patients with ischemic heart disease and of 21 healthy volunteers and were carried out on fasting individuals within 3 and 6 hrs after the loading. Alterations were detected in the lipoprotein system of the patients as compared with healthy persons. In the patients with ischemic heart disease content of apoI was not increased while subfraction of high density lipoproteins HDL3b was elevated within 3 hrs and cholesterol content was decreased within 6 hrs after the fatty loading. These alterations appear to be applicable as tests for detection of latent atherogenous defects in the HDL system.
