INFLUENCE OF METEOROLOGICAL FACTORS IN THE FOOTHILLS OF THE CARPATHIANS IN DIFFERENT SEASONS OF THE YEAR ON THE INCIDENCE OF HYPERTENSIVE CRISES

It is known that sharp changes of weather can lead to deterioration in health condition, strong and sudden increase of blood pressure and increase risk of fatal consequences among people who suffer from hypertension. The study includes materials of emergency cases in Ivano-Frankivsk station of emergency medical service of patients with hypertension in 2016 and meteor-ological figures at the relevant period. A special role in the formation of the adjustable body reactions to the changes of the environment (e.g. weather) belongs to the vegetative nervous system, which is the primary place of revealing of the meteorological influence on the human body. The state of general adaptive reaction of the vegetative system to the change of the meteorological factors was estimated according to time (SDNN, RMSSD) and spectral figures of cardiorhythmograph records. It has been established that during the first three months of the year the number of calls was 33.86 % from 12364 emergency health care units calls. Average monthly figures of atmospheric pressure in comparison to the numbers of calls of patients with hypertensive crisis showed that in January figures of atmospheric pressure were the lowest – (730.59±0,27) mmHg at the highest numbers of calls – 1446; in February (733.9±0.25) mmHg and 1347 calls; in March, correspondingly, (734.13±0.20) mmHg and 1394 calls. However, the fig-ures of relevant humidity in these months were, correspondingly, (84.62±0.64)%, (76.81±0.61)% and (72.49±0.78)%. At the second quarter, the percent level of calls was lower and accounted for 27.94%, the atmospheric pressure under it was (735.03±0.17) mmHg. At the next ІІІ and ІV quarters gained results were the next: the per-centage of calls was – 19.88% and 18.32%, atmospheric pressure – (738.53±0.08) і (739, 43±0.14) mmHg. In such a case figures of relevant humidity at the І-st і ІV-th quar-ters did not differ a lot – (77.97±0.62)% і (79.08±0.35) %, however the number of calls at the last quarter was 2265 against 4186 at the first one. The analysis of the meteorological figures and numbers of calls found out that in January, February, March the highest amount of calls did not depend on the figures of average minimum and maximum temperatures; as under the similar figures of air temperature outside their number in October, November and December were significantly lower. The analysis of emergency health care unit calls showed that the frequency of calls to patients with the hypertensive crisis correlated more with the decrease of atmospheric pressure (r = - 0.876, p˂0,05); less essential was correlation with figures of humidity – (r = - 0.119) and average daily temperature – (r = - 0.264). Under the treatment patients with hypertension, it is necessary to conduct medical correlation of meteorotropic reactions starting from 1-2 days before the weather change taking into account the state of patient and weather condition. According to the cardiorhytmograph records among pa-tients with the arterial hypertension and with excessive meteosensitivity, it was noticed some advantage of certain figures, which reflect, increased, sympathetic or mixed activity. To treatment hypertension, it is recommended to pay attention to the signs of excessive meteosensitivity; to estimate the tonicity of vegetative nervous system which primarly reacts to the weather change and if there are signs of meteorotropic reactions in patient, hypertensive treatment should be prescribed and includes measures aimed at the decrease of inadaptable influence manifestations caused by weather change.
