[Various periodical and aperiodical variations of heart infarct mortality in the DRG]

On the basis of 66.900 cases of death from ischaemic heart disease from 1970 to 1974, patient aged 70 years and younger, total statistics, an average quotient for the house/clinic-relation was calculated. The variations of the house/clinic-relation observed are subdivided into 3 stable periods: 24-hour periodicity, season periodicity and weekday periodicity (socially conditioned). These periods are superimposed by aperiodical influences. The relations between increased house/clinic-relation of the cases of death from ischaemic heart disease and the increased influences of the geomagnetic field as well as geomagnetic tempests (SSC). Here a significant positive connection for the indicators of activity as well as for the SSC was the result. One can issue from the fact that, the higher the ratio is the more unfavourable conditions for a specialised therapy of the complications of the ischaemic heart disease are existing. The cases in question in this phenomenon are new chronobiological knowledges which have a direct relation to the medical practice. Instances are given for the practical use in the prevention of complications of the ischaemic heart disease.
