[alpha-lipoprotein cholesterol and its variability in ischemic heart disease].

The authors conducted a repeated examination of 150 patients suffering from ischemic heart disease with normolipidemia and types IIa, IIb and IV hyperlipoproteinemia. The content of alpha-cholesterol in these patients tended to fluctuate, just as the content of other blood lipid fractions. Its fluctuations were most marked in types 11b and IV hyperlipoproteinemia.

[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.

[Types of hyperlipoproteinemia in young persons with ischemic heart diseases engaged in strenuous mental work].

The results subsequent to an examination of 250 males aged 30-47 suffering from ischemic heart disease and doing strenous mental work are presented. Two variants were used in phenotyping: the first was based on not too high criteria for the cholesterol and triglycerides level (250 and 140 mg%, respectively), the second one having as a groundwork upper limits of the normal value estimated by the authors (250 and 190 mg%, respectively). It was found that, depending upon the actual value of the upper normal limit for triglycerides hyperlipidemia is demonstrable in 64 or 56% of the males.
