“…В работе Karpin VA, et al [14] было установлено, что пики обострения артериальной гипертензии весной и осенью в г. Сургут (Ханты-Мансийский автономный округ России) совпадают с максимальной среднемесячной величиной и с максимальной среднемесячной вариабельностью атмо сферного давления. Об изменениях АД при колебаниях атмосферного давления сообщается и в других публикациях [18,30,36,56]. Действие атмосферного давления на организм связывают с его влиянием на оксигенацию крови [29], а также с непосредственным воздействием на трансмуральное давление сосудов [30,57,58].…”

Many clinical studies have shown seasonal dynamics of blood pressure (BP), which most authors attribute to seasonal variations in air temperature. However, the fact that in the conditions of modern urban society the influence on the person of air temperature on the street is minimized, as well as the fact that the seasonal dynamics of BP is observed and in a tropical climate contradict this statement. It is known, that the length of the day, the atmospheric pressure, the relative humidity, geomagnetic activity are subject to seasonal dynamics. Studies have shown that fluctuations in these meteorological factors can cause change in blood pressure.Aim.To use meta-analysis of the results of studies, conducted in different climatic zones (from subarctic to tropical) and devoted to seasonal dynamics of BP, to determine which meteorological conditions most often corresponded to the annual maximum of BP and which to the annual minimum of BP.Material and methods. We selected 15 publications about seasonal dynamics of BP and seasonal exacerbations of arterial hypertension in 21 regions of the Northern Hemisphere of the Earth.Results.We confirmed that, in addition to air temperature, other factors are also subject to seasonal dynamics (atmospheric pressure, relative humidity, partial oxygen density in the air). No correlation was found between the amplitude of seasonal fluctuations in air temperature and the amplitude of seasonal fluctuations in BP. In addition, the amplitude of drcannual blood pressure fluctuations was greater in regions with a clear seasonal dynamics of the average monthly atmospheric pressure, compared with regions in which the this parameter does not have a clear seasonal dynamics. Also, in some regions, the seasonal maximum of BP coincided with high geomagnetic activity.Conclusion. According to the results, we concluded that seasonal fluctuations of BP are not a reaction of the cardiovascular system to seasonal dynamics of air temperature only. Most likely, seasonal fluctuations of BP are caused by changes in all meteorological factors that have seasonal dynamics.
