“…2000), where a heat wave is described as at least a three-day period of maximum temperature ≥ 32.2°C (90°F). A heat wave (temperature wave) can also be defined as a period of 5 consecutive days with a temperature > 22.7°C including at least three days with a temperature > 25°C (Ozheredov et al 2010). Besides this, a heat wave can also be defined as a six-day period of apparent temperature (AT) above the 95th percentile and beginning with a temperature increase of at least 2.0°C on the previous day (Kuchcik, Degórski 2009), or as a period > 5 consecutive days with Tmax > 5°C above the 1961-1990 daily Tmax normal (IPCC 2001;Frich et al 2002;Unkašević, Tošić 2009).…”

This article aims to describe heat waves in Eastern Europe and to determine the synoptic situations which cause them. In this article, a hot day is defined as the one with a maximum temperature above the 95th percentile of all the values in the analysed period, and a heat wave is considered as a sequence of at least 5 such days. In the analysed period and within the investigated area, from 24 (Kaliningrad) to 55 (Kharkiv) heat waves were observed. The longest heat wave was recorded in Moscow in 2010, lasting as many as 45 days. In the analysed period, an increase in frequency and length of heat waves was observed within the analysed area. The occurrence of heat waves was connected with a high pressure system located over the eastern part of the continent, during which positive anomalies of sea level pressure and the 500 hPa geopotential height as well as positive T850 anomalies were recorded.

“…Nevertheless, morbidity and mortality from CVD remain high. It is hypothesized that environmental factors such as the local Earth's magnetic field activity may also be significant in the development of CVD [11,12]. Disruption of the local Earth's magnetic field causes severe adaptive stress at all levels of body regulation [7,9,10].…”

Stronger oscillations in the local Earth magnetic field may have an impact on the course of ischemic heart disease. This effect is individual for every person and depends on the sex, age, living territory, season, capability to adjust to magnetic field fluctuations and health status. Individuals who already have cardiovascular disease are more sensitive to magnetic field fluctuations, therefore further research is needed to make conclusions. Aim: To identify correlations between changes in local Earth magnetic field frequencies and patients with ST segment elevation myocardial infarction (STEMI) and non-ST segment elevation myocardial infarction (NSTEMI) cases per week, cases by sex per week and patients’ blood laboratory parameters (low-density lipoprotein cholesterol and Troponin I level). Methods: A retrospective study of 1667 patients, who were admitted to the Hospital of Lithuanian University of Health Sciences Kaunas Clinics between 1st January and 31st December 2019 due to acute coronary syndrome (STEMI and NSTEMI), were included in the study. Local Earth's time varying magnetic field (TVMF) was measured by a magnetometer located in Baisogala, Lithuania. Data from the magnetometer was collected daily, and weekly averaged. We assessed the correlations between average weekly geomagnetic field strength in six different frequency ranges (Hz) and average number of STEMI and NSTEMI cases per week, cases by sex per week and patients’ blood laboratory parameters (low-density lipoprotein cholesterol and Troponin I level). Results: The presence of a stronger magnetic field in the frequency range of 32-65 Hz was significantly related to the number of cases in the STEMI group during the winter season (r= 0.583, p= 0.036). Tendency towards a positive correlation was found during the winter in the men's group with STEMI in the high frequency range of 32-65 Hz. Low-density lipoprotein cholesterol level correlated positively in the winter STEMI group with the magnetic field in the 32-65 Hz range, and in the autumn STEMI group with the magnetic field in the frequency range of 0-7 Hz. Conclusion: Increased geomagnetic field strength in the high frequency range of 32-65 Hz is associated with a higher number of cases in the STEMI group.

“…It was noticed that birds, sh, and insects navigate in the environment mainly by Earth geomagnetic eld oscillations [1]. Interestingly, geomagnetic eld (GMF) impact on the tone of the vascular wall has been repeatedly proved, [2][3][4][5][6][7][8] highlighting that GMF changes independently to other geomagnetic climate factors strongly modulate blood pressure (BP) changes [2]. Even more, it was noticed that geomagnetic storms (GMS) created by solar ares [2] misbalancing adaptive mechanisms and causing severe adaptive stress responses most heavily impact cardiovascular system regulation mechanisms [9,10] manifesting as decrease of the heart rate variability (HRV) and blood ow, and increase in platelet aggregation activity, coagulation, and blood viscosity even in healthy people [9].…”

Background: Geomagnetic storms strongly affect the human cardiovascular system, misbalancing adaptive mechanisms and causing severe adaptive stress responses at all levels of body regulation. Most physiological changes occur after a defined period following geomagnetic climate alterations, this ‘delay period’ lasts for 2-3 days. Methods: In total, 4730 patients admitted between 2015 and 2017 due to acute coronary syndrome (ACS) and acute onset of arrhythmias have been included into the study.Results: Higher time varying magnetic field (TVMF) activity in low frequency ranges is associated with lower number of admissions due to ACS, while higher TVMF activity in high frequency ranges is associated with increased risk for ACS occurrence. The greater TVMF activity in low frequency ranges is associated with higher rates of admission due to cardiac arrhythmias. Additional ACS analysis showed that red blood cell count decreases with increased MF strength in low frequency ranges, while white blood cells and platelets count increases in the same MF frequency ranges. The highest serum osteocalcin level was found 3 days after certain MF strength changes in low frequency ranges in patients with ACS. Strong correlations were found between more than 2 cases of AMI per day and MF strength changes 2- and 3- days before admission. Conclusions: Earth’s local magnetic field is strongly related on human cardiovascular system metabolism and neural regulation. Increased Magnetic field activity in low frequency ranges is associated with heart metabolism and may induce better cardiovascular health, while increased magnetic field activity in high frequency ranges leads to heart problems especially to occurrence of ischemic heart disease and arterial hypertension.
