The first paragraph is an introduction. Ischemic heart disease is the first on the list of the top ten most common causes of death in 2016, according to WHO figures, independent of the state's economic status. A study was done to learn more about whether and to what extent ischemic heart disease mortality is linked to external factors such as the planetary magnetic field, solar radiation, and galactic cosmic rays.
Methods and Materials: Ischemic heart disease mortality statistics from credible statistical sources - Eurostat, OECD, UN statistics, and the Bulgarian National Statistical Institute – were utilised from 2005 to 2017. Data on solar corpuscular radiation was gathered from the Geostationary Operational Environmental Satellite series at a NOAA location (GOES). PSTAR and ASTAR databases and calculators were used to calculate the journey length and energy of high-energy protons and alpha particles through the atmosphere. The geomagnetic field data for Bulgaria was collected from the INTERMAGNET website. For 5 European neutron monitors, data on galactic cosmic rays was gathered from the NMDB database. The data was processed using correlation and regression analysis.
Results: A strong statistically significant link was discovered between annual fluxes of protons and alpha particles on the one hand, and male and female ischemic disease mortality in a variety of European and Asian nations on the other. The reliance of female ischemic heart disease on alpha-particle flux for Bulgaria has the highest correlation coefficient: 0.939, with a statistical significance level of 0.001. Date intervals with intense alpha particles and proton fluxes, as well as ischemia mortality, are presented as examples.
Discussion Points: The findings point to a possible causative link between ischemic heart disease mortality and solar positive corpuscular radiation fluxes. In Bulgaria, these effects were predicted to contribute 10% to the risk of death from ischemic heart disease. A method is hypothesised in which positively charged high-energy solar particles enter the atmosphere and reach the earth's surface through sites where the particles are not influenced by the earth's magnetic field, i.e. where the condition of parallel induction of the earth's magnetic field and particle invasion in the atmosphere is met. This condition allows for the calculation of the width of the impact zone - between 28°N and 48°N - as well as the dates of elevated danger for sites on the earth's surface inside this zone. The energy necessary for the particles to overcome interactions with particles in the atmosphere was calculated to be between 2.5 and 3.4 GeV for protons and 6.2 to 7.5 GeV for alpha particles. In geostationary orbit, a large flux of alpha particles with energy above 3.4 GeV is recorded, but the proton flux with energies above 0.7 GeV is hundreds of times smaller, according to satellite observational data (GOES 13). This makes it more likely that high-energy alpha particles reach the earth's surface, where they act as a trigger for circulatory processes that cause death, especially in the elderly.
