Abstract [eng] |
Ischemic heart disease (IHD), in clinical practice manifesting as acute coronary syndrome (ACS), might be understood as a disruption of intracoronary blood flow decreasing oxygenated blood supply to the heart muscle. Oscillations of the local time varying magnetic field (TVMF) effects such human cardiovascular system indicators as blood pressure (BP), heart rate (HR) and its variability. This might be the foundation for magnetic activity association to increased occurrence of IHD and myocardial infarction (MI). An attempt is being made to discover new promising methods to reduce and prevent cardiovascular disease and its complications. Methods: Seven-hundred patients admitted to Cardiology Department of Hospital of Lithuanian University of Health Sciences Kaunas Clinics within 2016 due to acute coronary syndrome were retrospectively included into the study. The number of cases per week was compared with the weekly changes of the local Earth magnetic field. Results: Significant correlations between weekly occurrences of ACS cases and the average weekly TVMF strength were found. In the analyses of the whole year model two positive weak and moderate correlation coefficients in SBeta [15;32] (r=0.06, p=0.65) and SGamma [32;65] (r=0.27, p=0.05) ranges in the female group were found, respectively. In males there was no significant correlations in analyses of the whole year model. When one-year period was divided into two-time intervals, further analyses revealed that the first-half of the year had the same tendencies in the females with a single positive moderate correlation coefficient in SGamma [32;65] range (r=0.28, p=0.05) (Figure 2 A.). In males there were tendencies towards weak to moderate positive correlation coefficients (p<0.1) at all frequency ranges in the second half of the year, which are detailed in Figure 2 B. There were no differences between ACS cases in male and female though the second-half of the year. Conclusions: Significant correlation between acute coronary syndrome and the local Earth magnetic field changes was revealed. The acute coronary syndrome is positively correlated with the local Earth magnetic field in SGamma range in female through the year. A higher magnetic field in SBeta and SGamma ranges is associated with higher incidences of acute coronary syndrome through the year in females. The higher magnetic field in SGamma range is associated with higher incidences of acute coronary syndrome through the year in females and through the second-half of the year in males. |
