“…This let presume that a higher LMF intensity in high frequency range is associated with more severe deterioration of patients with IHD health condition [29]. Scientists analysing LMF, have concluded that LMF in low frequency ranges has positive in uence on patients with IHD wellbeing [30]. It has recently been found that endothelial function is enhanced by LMF oscillations at extremely low frequencies (0.01-0.02 Hz) [30].…”

“…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]. Nevertheless, it has been shown in many studies that physiological changes occur with a delay after the change in magnetic or solar activity [9,[11][12][13][14]. The phenomenon is called 'delay phase' and take from hours up to 2-3 days following GMF alterations [9,[11][12][13][14].…”

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.

Aim of this paper is to reveal whether the geomagnetic activity (GMA) and meteorological factors (MFs) affect vascular parameters of healthy volunteers. As a trial study we used new device "Tonocard," and new vascular parameters for study-a pulse wave velocity (PWV) and an endothelial function (EnF) in addition to blood pressure measurements. These parameters never investigated before in such aspects. As far as novelty of device itself and investigated parameters we limited ourselves by monitoring only four healthy volunteers (without cardiovascular pathology). To analyze the sensitivity of their aforementioned medical indices to GMA and MFs two independent mathematical approaches were used, one of whom is based on traditional methods of mathematical statistics and the other on the theory of pattern recognition Dependence of physiological characteristics on the atmospheric temperature, revealed by both applied mathematical approaches, showed complex non-linear character of biological replies: the reaction has a different form in different temperature ranges and is manifested in the form of synchronization of slow variations of physiological and atmospheric parameters (trends) with a period of several days, while the daily variations were virtually independent. The systolic blood pressure (SBP), PWV and a difference between two specially selected values of PWV (DPWV) are approximately equally depending on atmospheric temperature, which accounts for an average of 26% to 28% of their variations. Sensitivity to the GMA for this test was found only for PWV.

The association between phenomena on the Sun, geomagnetic activity, meteorological variables, and cardiovascular characteristic of patients with myocardial infarction

It has been found that solar and geomagnetic activity affects the cardiovascular system. Some evidence has been reported on the increase in the rate of myocardial infarction, stroke and myocardial infarction related deaths during geomagnetic storms. We investigated the association between cardiovascular characteristics of patients, admitted for myocardial infarction with ST elevation (STEMI), and geomagnetic activity (GMA), solar proton events (SPE), solar flares, and meteorological variables during admission. The data of 1,979 patients hospitalized at the Hospital of Lithuanian University of Health Sciences (Kaunas) were analyzed. We evaluated the association between environmental variables and patient's characteristics by multivariate logistic regression, controlling patient's gender and age. Two days after geomagnetic storms the risk of STEMI was over 1.5 times increased in patients who had a medical history of myocardial infarction, stable angina, renal or pulmonary diseases. The dose-response association between GMA level and STEMI risk for patients with renal diseases in history was observed. Two days after SPE the risk of STEMI in patients with stable angina in anamnesis was increased over 1.5 times, adjusting by GMA level. The SPE were associated with an increase of risk for patients with renal diseases in history. This study confirms the strongest effect of phenomena in the Sun in high risk patients.
