Abstract

Aim. To determine if complicated acute myocardial infarction (AMI) is related to specific cosmophysical activities. Methods. The study group included 1170 patients who had undergone primary percutaneous coronary intervention (PCI) for AMI in 2000-2006. Geomagnetic and cosmic ray (neutron) activity (GMA, CRA) on the day of PCI were derived from international observatories. The findings were compared among patients with right ventricular infarction (RVI), cardiogenic shock, and uncomplicated AMI. Results: Relative to the whole study period, the mean CRA was higher on days on which PCI was performed for RVI (n = 123, 10.5%) (p =.0003) and cardiogenic shock (n = 102, 8.72%) (p =.018). When the same artery was involved (LAD, RCA, CRX), CRA was significantly higher for complicated than for uncomplicated AMI (RVI group: p =.006, p =.00027, p =.014, c ardiogenic shock; p =.009, p =.029, p =.089, respectively). At the highest levels of GMA, more RVI cases were seen than cases of cardiogenic shock (p =.06). Conclusion: RVI and cardiogenic shock were associated with higher CRA than uncomplicated AMI. RVI occurred more often on days of high GMA than cardiogenic shock. Higher CRA may induce more myocardial damage in patients predisposed to AMI.
