title: [Various features of the hemodynamics of native inhabitants of different mountainous zones of the Mongolian People's Republic].
abstract: The native inhabitants of Mongolia living at relatively moderate altitudes (2200-2300 m) showed a statistically decreased heart rate, elevated venous pressure, cardiac output and stroke volume as well as a reduced rate of the blood flow which should be considered as compensatory responses to high altitude and cold hypoxia. In inhabitants of colder zones the systolic pressure was 132 +/- 1.2 mm Hg, the diastolic pressure was 83.8 +/- 0.6 mm Hg as against 122.8 +/- 1.0 and 77.6 +/- 0.6 mm Hg, respectively, in inhabitants of warmer zones (p less than 0.01). The incidence of blood hypertension in 40-69-year-olds in cold zones equaled 19 +/- 2.5% as compared to 8.3 +/- 2.1% (p less than 0.01) in warmer high altitude zones. No correlation was found between the subjects' blood pressure and the altitude of their place of living which suggests that high altitude hypoxia has no decisive effect on the blood pressure and that the significantly higher prevalence of hypertension in cold zones can be explained by the impact of a complex of adverse climate and geographic factors, with low temperatures being especially important.
