[Lipid level in the blood, based on multiple study data, and the characteristics of the course of ischemic heart disease].

The blood lipid content and lipoprotein spectrum were repeatedly tested in 216 males with ischemic heart disease for follow-up periods of 4 to 5 years. Irrespective of the type of hyperlipoproteinemia, the blood triglyceride level was marked by the greatest individual fluctuations and the level of total cholesterol by the least fluctuations. Comparison of the clinical course of ischemic heart disease with the peculiarities of the changes in the blood lipid content revealed a higher incidence of recurrent myocardial infarction and sudden death among individuals with type IIa hyperlipoproteinemia. Recurrent vascular catastrophes were observed not only in patients with stable hypercholesterolemia but also in individuals with its labile form. It is concluded that repeated tests for the blood lipid content provide for more reliable diagnosis of hyperlipidemia and the type of hyperlipoproteinemia, which is of unquestionable practical importance.
