The culprit artery in acute myocardial infarction in different environmental physical activity levels.

Background: The timing of acute coronary events may be related to endogenous and exogenous--environmental--factors.

Aim: To check if daily levels of geomagnetic activity (GMA) and/or cosmic ray activity (CRA) measured by neutron activity (imp/min) on the Earth's surface are related by timing with specific culprit artery of AMI.

Patients And Methods: Data of PCI for AMI (n=904, 696 men) from 01/2000 to 02/2006 (2251 days) were used for analysis.
