[The characteristics of the lipid-hormonal interrelations in young men with a history of myocardial infarct (based on family registry data in Novosibirsk and Bishkek)].

Altogether 226 male probands who suffered large-focal or transmural myocardial infarction (MI) before reaching 50 years were examined in Novosibirsk and Bishkek in one stage according to the unified program. In Novosibirsk all the probands were Russians whereas in Bishkek 75 probands were Kirghizs and 71 were Russians. The probands were examined within a period of 1 to 3 years after MI. The lipid and lipoprotein plasma content was determined by standardized methods on a Tekhnikon AAP autoanalyzer. The content of thyroid hormones, insulin and cortisol was measured by means of RIA-kits and that of apolipoprotein B (ApoB) by radial immunodiffusion. It turned out that the patients from Novosibirsk demonstrated the highest content of cholesterol, low density lipoprotein cholesterol, the highest index of atherogenicity, the highest concentration of ApoB, and hyperinsulinemia. In the probands of both nationalities from Bishkek, the lipid spectrum did not differ substantially from the populational norm, the content of ApoB in the Russian probands was slightly lower than in those from Novosibirsk whereas in Kirghizs, the least content of thyroxin was recorded.
