Acute coronary syndrome due to left main disease association with changes in local earth’s magnetic field

Abstract

Introduction. Ischemic heart disease (IHD), manifesting as acute coronary syndrome (ACS), affects younger and increasing number of patients worldwide (1-2). The most life threatening is ACS caused by left main (LM) disease resulting in severe cardiac damage (3). Despite many studies, there are some unclear aspects of development of ACS, as sometimes multiple cases occur. Recent studies have suggested the hypothesis of local Earth’s magnetic field (TVMF) intensity changes provoking cardiac events (4-6). Research aim. To evaluate correlation between acute coronary syndrome due to left main disease and changes in local Earth’s magnetic field intensity. Research methods and organization. In total 68 patients (22 female and 46 male) admitted to the Cardiology Department of Hospital of Lithuanian University of Health Sciences Kaunas Clinics due to ACS caused by LM disease between 1 January 2016 and 31 December 2016 were included into the study. One-year period was analyzed as whole and divided into two halves of the year. The TVMF intensity was observed in five frequency intervals [Hz]: SDelta[0-3.5], STheta[3.5-7], SAlpha[7-15], SBeta[15-32], SGamma[32-65]. Data was collected from local magnetometer located in Lithuania, which is a part of the Global Coherence Monitoring Network. Weekly averaged TVMF intensity was compared with weekly averaged cases of ACS due to LM disease. SPSS 20.0 was used for statistical analysis. [...].
