A substantial body of research has demonstrated the relationships between cardiac arrhythmias and geomagnetic activity. In this work, the idea is centered on finding the relationship between the local magnetic field (LMF) and acute myocardial infarction (AMI). It is hypothesized and demonstrated via a series of statistical analyses that the relationship between the LMF and AMI is maintained over long-term observation windows. The data are collected from the two hospitals and one public institute of health in Lithuania from 2014 till 2019. The data are categorized into (1) daily average of the Schumann resonance for the local magnetic field measured by the Lithuanian magnetometer, which is used as the input variable; and (2) the total number of patients hospitalized in Lithuania per day with the diagnosis of AMI (the output variable). The data are classified both weekly as well as by gender. Following the data categorization and classification, the data were subjected to rigorous statistical analysis to determine the relationship between the input and output variables. This paper shows that only the beta and gamma (S-beta, S-gamma) frequency ranges of the Schumann resonances contribute to maintaining the long-term relationship between the LMF and AMI.

Changes in geomagnetic conditions have been shown to affect the rhythms produced by the brain and heart and that human autonomic nervous system activity reflected in heart rate variability (HRV) over longer time periods can synchronize to changes in the amplitude of resonant frequencies produced by geomagnetic field-line and Schumann resonances. During a 15-day period, 104 participants located in California, Lithuania, Saudi Arabia, New Zealand, and England underwent continuous ambulatory HRV monitoring. The local time varying magnetic field (LMF) intensity was obtained using a time synchronized and calibrated network of magnetometers located at five monitoring sites in the same geographical locations as the participant groups. This paper focuses on the results of an experiment conducted within the larger study where all of the participants simultaneously did a heart-focused meditation called a Heart Lock-In (HLI) for a 15-min period. The participant's level of HRV coherence and HRV synchronization to each other before, during and after the HLI and the synchronization between participants' HRV and local time varying magnetic field power during each 24-h period were computed for each participant and group with near-optimal chaotic attractor embedding techniques. In analysis of the participants HRV coherence before, during and after the HLI, most of the groups showed significantly increased coherence during the HLI period. The pairwise heart rhythm synchronization between participants' in each group was assessed by determining the Euclidean distance of the optimal time lag vectors of each participant to all other participants in their group. The group member's heart rhythms were significantly more synchronized with each other during the HLI period in all the groups. The participants' daily LMF-HRV-synchronization was calculated for each day over an 11-day period, which provided a 5-day period before, the day of and 5-days after the HLI day. The only day where all the groups HRV was positively correlated with the LMF was on the day of the HLI and the synchronization between the HRV and LMF for all the groups was significantly higher than most of the other days.

We investigated whether extremely geomagnetic activity may modify the association between short-term nitrogen dioxide (NO2) exposure and emergency hospitalization for acute coronary syndrome (ACS). A case-crossover study design was used to analyze ACS in 6,594 hospitalized patients at the Clinic of Kaunas, Lithuania. We evaluated the associations between NO2, geomagnetic activity and the rate of emergency admissions for ACS by logistic regression controlling for seasonal variation, weekdays and meteorological factors. Ambient NO2 pollution interquartile range increase (IQR) on the day of admission and previous day (lag 0-1) in patients below 65 years of age increase the risk of ACS equal to 24% (95% CI 0.96-1.60). Evidence of effect modification by combined NO2 and geomagnetic activity was observed in relation to ACS, adjusted OR was 1.61; 95% CI 1.03-2.53. In conclusion, these findings suggest that geomagnetic activity variations may increase the traffic-related air pollution effect on ACS, and highlight environmental factors associated with ischemic heart disease course.

Abstract  The prognostic relationship between a decrease of hard cosmic ray flux (HCRF) and subsequent leaps in cardiovascular disease (CVD) occurrence within 1–3 days is well known. The influence of meteorological situations on human health is also known. However, no correlation was found between a simultaneous decrease of HCRF and atmospheric pressure and the leaps of CVD on some days. For the analysis of a prognostic connection between these parameters, empirical criteria have been put forward. To achieve effective results from analysis, the criteria of a continuous decrease of HCRF to 200 impulses or more within 4 h and of atmospheric pressure by 2 mmHg or more were used. CVD leaps were considered real when their number increased by 10% or more in comparison with the average monthly value. The highest prognostic correlation between HCRF decrease and CVD leaps within 1–2 days was from 64 to 76%. The correlation within 2–3 days was lower. The correlation between atmospheric pressure decrease and leaps of CVD in 1–2 days and on the same day was 25–44%. It means that, while studying the meteorological effects on human organisms, other parameters such as temperature, humidity, wind velocity, etc. should also be taken into account. An essential role in reducing the prognostic accuracy of CVD leaps by a decrease of HCRF relates to the human factor. [ABSTRACT FROM AUTHOR]
