[The effect of a one-time fat load on indicators of the plasma lipoprotein system in patients with ischemic heart disease and in healthy patients].

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.
