[The epidemiology of ischemic heart disease in men and women 25 to 54 in relation to their levels of physical activity]. / Epidemiologiia ishemicheskoi bolezni serdtsa u muzhchin i zhenshchin 25-54 let v zavisimosti ot urovnia fizicheskoi aktivnosti.

A one-stage populational study of a random representative sample of the nonorganized community of Novosibirsk was carried out within the framework of the WHO CINDI and MONICA projects. There were 1235 men and 1113 women aged 25-54 years. The prevalence of coronary heart disease and the main risk factors was studied in quartiles of energy losses distribution during occupational physical activity (OPA) and physical activity at leisure (PAL). The men demonstrated a nonlinear relationship between the prevalence of the painless form of CHD and the level of OPA, which manifested in a considerable increase of the incidence of that CHD form in the 2nd and 4th quartiles of OPA (Friedman's criterion S = 69, p < 0.003). The women showed a nonlinear relationship between CHD prevalence on the whole and the level of OPA, characterized by a noticeable increase of the incidence of the above-indicated form of CHD in the 2nd and 4th quartiles of OPA (S = 62, p < 0.02). Besides, the women demonstrated an increase in the incidence of CHD on the whole in the 4th quartile of PAL (S = 69, p < 0.003).

[The iron deficiency status and the actual nutrition of women in Gorno-Altai]. / Zhelezodefitsitnye sostoianiia i fakticheskoe pitanie zhenshchin Gornogo Altaia.

Standard methods (questionnaires, peripheral blood count, iron pool) were employed to study epidemiology (prevalence and risk factors) of iron deficiency in the women of the Altai mountains and the relation of this deficiency with essential nutrition. Hemoglobin dispersion was found to depend on fuel value of the ration, total protein levels, polyunsaturated fatty acid content.

[The prognosis of the course and outcome of small-focus myocardial infarct depending on the T-index values on the ECG based on data from the Novosibirsk Myocardial Infarct Registry program]. / Prognozirovanie techeniia i iskhodov melkoochagovogo infarkta miokarda v zavisimosti ot velichin T-pokazatelia na EKG po materialam programmy "Registr infarkta miokarda" Novosibirska.

Overall 342 patients with small-focal myocardial infarction were analyzed for hospital complications and for outcomes during one- and four-year observation periods in groups with different magnitudes of the T parameter. The latter one is the negative T wave on the ECG computed similarly to the Z. L. Dolabchian's index for Q and R waves on days 1-2 and 28 of myocardial infarction. The use of the T parameter allows predicting the most frequently occurring complications during the hospital observation period and recurrent myocardial infarction and cardial death during the period indicated. In the acute stage, the magnitudes of the T parameter from 1 to 24 conventional units are predictors of the complications: lung edema, cardiogenic shock, rhythm disorders, myocardial infarction relapses, particularly in able-bodied men. If the T parameter amounts from 78 to 648 conventional units in the acute stage and on day 28, this suggests a high risk of repeated myocardial infarction and cardial death for one- and 4-year observation periods in accordance with materials of the "Myocardial Infarction Register" program in Novosibirsk.
