Geomagnetic activity related to acute myocardial infarctions: Relationship in a reduced population and time interval

We use medical data of acute myocardial infarctions for 5 hospitals in the city of Havana covering an estimated population of 850 000 inhabitants during the years 1992 to 1999. We analyze the occurrence of infarctions in relation to geomagnetic activity through the Ap index considering low and high...

We analyze the occurrence of infarctions in relation to geomagnetic activity through the Ap index considering low and high activity levels. The distribution of the infarctions in geomagnetically calm (Ap<10 g) and geomagnetically perturbed (Ap >50 g) periods is different.

Analizamos la ocurrencia de estos infartos en relación con la actividad geomagnética medida a través del índice Ap, considerando un rango de actividad que va del bajo al alto. Encontramos que la distribución de infartos en períodos geomagnéticos tranquilos (Ap<10 g) y perturbados (Ap>50g) es diferente. Empleando el método de épocas superpuestas, observamos un máximo prominente en la distribución de infartos un día después del día del máximo de Ap. Aparentemente la morbilidad por infarto agudo al miocardio responde a un nivel umbral de actividad geomagnética de Ap entre 20- 50 g.Universidad Nacional Autónoma de México.
