[Functional classification of ischemic heart disease]. / Funktsional'naia klassifikatsiia bol'nykh ishemicheskoi bolezni serdtsa.

A modified variant of the functional classification of patients with ischemic heart disease standard for all stages of rehabilitation is suggested. It is based on the rate with which the program of treatment is fulfilled and on the determination of the clinico-functional parameters and the physiological reaction of the patient during rehabilitation. The classification was tested on 98 patients with macrofocal myocardial infarction (average age 53.5 years) who underwent a successive rehabilitation program at the inpatient, sanatoria, out-patient stages with a subsequent two-year follow-up as out-patients after they had resumed working. The classification proved sufficiently informative in regard to the prognostication of the restoration of working capacity and the character of the course taken by ischemic heart disease.

[Adaptive characteristics of growth of human embryos and fetuses during the intrauterine life]. / Adaptatsionnye osobennosti rost chelovecheskikh zarodyshei i plodov vo vnutriutrobnoi zhizni

Under observations was the dynamics of growth of human embryos and fetuses in embryogenesis which is directly dependent on the month of the intrauterine life. Coefficients of correlation and regression were calculated and with their help the average growth of the general length of fetuses in each month of prenancy was determined. The enlargement of the fetus length was found to be more intensive in the embryonic and prefetal periods.

[Factors affecting restoration of work capacity after myocardial infarct]. / Faktory, vliiaiushchie na vosstanovlenie trudosposobnosti posle infarkta miokarda

The effect of some clinical peculiarities of the disease upon the restoration of the patient's capacity for work was studied along with the factors increasing the risk of repeated disablement after resuming the professional functions. The discussion is based on the results obtained in an out-patient study of 285 males who have been employed before their myocardial infarction in administrative-managerial jobs. Three groups of factors characterizing the functional state of the cardiovascular-system in the pre-infraction, acute and post-infarction periods are distinguished. It was demonstrated that the functional state of the heart when the patients resumed their work was characterized by the degree of chronic coronary and cardiac insufficiency, the scope of every-day physical activity, and was one of the essential criteria for the evaluation of the degree of rehabilitation. The first group of factors (essential hypertension, chronic coronary insufficiency preceeding the development of myocardial infarction) and the second group (clinical and anatomical peculiarities of acute myocardial infarction) are of secondary importance in determining the degree of rehabilitation. At the same time, the functional background of the cardiovascular system teinted prior to the infarction and the depth of the infarction, as well as the reduced level of the heart's functional capacity before resuming the professional functions, belong to the factors that increase the risk of secondary disablement in persons who have resumed working after a sustained myocardial infarction.
