[Prevalence of arterial hypertension, ischemic heart disease and their risk factors in geologists in various regions of the USSR].

The authors presented the results of an epidemiological survey conducted simultaneously for the first time among persons of geological professions in order to reveal the prevalence of arterial hypertension (AH) and coronary heart disease (CHD) with account of labor intensity, climatic and geographic factors. Altogether 1041 men were examined in 4 regions: in Vorkuta (a trans-polar region), Ukhta (a northern region), Chita and the Central region. The highest AH prevalence was detected in Vorkuta (27.

[Therapeutic effect of trandat, an alpha- and beta-adrenergic receptor blockader, and its effect on central, regional and intracardiac hemodynamics].

A study of the effect of labetalol (trandat) was carried out in 75 arterial hypertensive patients. The central, regional, and intracardial hemodynamics were studied in 40 of them by echocardiography and rheography. A 25% decrease in BP and subjective improvement were observed on the 1-2 week of treatment.

[Characteristics of central and regional hemodynamics in certain variants of the course of myocardial infarct].

In 96 patients with myocardial infarction the indices of central hemodynamics were studied by radiocardiography and the indices of regional circulation in the brain, lungs, liver, and distal parts of the extremity by rheoplethysmography. Peculiarities of regional and central hemodynamics depending on the clinical picture were revealed and the dynamics of the indices being studied were followed from the first to the 40th day of the disease. The authors discuss the mechanisms of the hemodynamic disorders and express their opinion on the expediency of the appropriate approaches to the treatment of patients depending on the hemodynamic changes revealed.
