The timing and outcomes of cardiovascular diseases are linked with surrounding power fields. In recent publications it was shown that occurrence and deaths from AMI, a pathology in 3/4, or more connected with atheroma- plaque rupture or fissuring, is significantly connected with Cosmic Ray (CRA) activity, measured by Neutron activity (imp/min) on the Earth surface and inverse related to Solar (S.A.) and Geomagnetic (GMA) activity, serving as shields of the Earth from Cosmic Rays.

Aim: of this study was to check if AMI number is changing after days of Zero GMA/high Neutron activity in years 2000-2007.

Patients and Methods: 8920 AMI patients (5307, 59.5%, men) daily admissions at the departments of Cardiology of Kaunas Medical Sciences University Hospital were studied. This data was compared with daily GMA and CRA levels. We found 36 days with Zero GMA, accompanied by High CRA (Neutron) activity. AMI daily number at day of Zero GMA, 1, 2 days after the Zero day, and 7 days (including Zero day) and 6 days after (excluding Zero day) were accounted and compared with AMI on Zero day of GMA. The cosmophysical data came from Space science Institutions in the USA, Russia and Finland .

Results: the daily average for Neutrons for the whole period (2000-2007) was 8883+-518 imp/min..For days of Zero GMA 9247+-402, p<0.0001.The daily AMI on day Zero was 2.51+-1.463, n-88; next day 3.09+-1.931,n-108, (p=0.01); second day post Zero-3.09+-1.579, n-108, (p=0.008); 6 days post Zero 2.98+-0.819 daily, p=0.008 compared to Zero day). It was a 23% raise of AMI at 1 and 2 days post Zero GMA/High Neutron day and 18% rise in average at 6 days post the studied event.

Discussion: it’s presumed that high Neutron activity may be one of factors involved in the damaging process of the Coronary plaque, one of the important pathogenesis factors in AMI occurrence.

Conclusion: at6 days following Zero GMA/high Neutron (CRA) it’s a significant raise of AMI patients. Neutron activity can be involved in the process of atheroma - plaque damaging and development of Atherothrombosis and AMI, explaining observed in many studies timing of the disease.
