Aim. A great number of authors all over the world have studied the possible incidence of several climatic or meteorological factors on human health, in particular on the ischemic events; with our study we try to demostrate the existence of a relation between solar activity (solar fields and geomagnetic activity), seasons and the most frequent acute vascular accidents: spontaneous rupture of infrarenal adbominal aortic aneurysms and acute limb ischemia.
Methods. We considered the correlation between solar activity (expressed as solar spots and geomagnetic activity) and acute vascular pathologies (by means of a retrospective analysis of all surgical operations performed between 1992 and 1996 for ruptured abdominal aortic aneurysm and for acute limb ischemia). The seasonal dependence of the ischemic coronary pathology is well documented, while the influence of seasons on others vascular districts has been studied less deeply, often with discordant results.
Results. We show a statistically significant seasonal dependence of the frequency of ruptured aneurysms and of the limb acute ischemia: in particular, aneurysms are more frequent in the second quarter with respect to ischemias, while the opposite happens in the third quarter. Finally, we have observed an inverse relation between solar spots and ischemias.
Conclusions. A relationship, between certain vascular pathologic events, among the most dramatic and life threatening and the presence of more or less intense solar activity, probably exists; its demonstration can disclose interesting sceneries of further research leading to results that now can’t even be anticipated.
