| Abstract: |
The overall mortality and cardiovascular mortality data from Romania within 1989–1995 were processed. They exhibit an increase by about 10% caused by the increase of inhabitants and by the increase of their average age. The percentage of cardiovascular mortality increases as well. Both data series display a pronounced annual wave supplemented by a smaller semiannual wave, resulting in a double maximum in January and April and a minimum in August. There is also a variation with the social week, given by a combination of the 7-day and 3.5-day wave, with a maximum on Thursday and Sunday and a distinct minimum on Friday. The mortality depends also on the lunar synodic cycle. This variation has a form of the semilunar wave with maxima two days before first and last quarter. The difference in the mortality between maxima and minima was tested and appeared to be significant. The semilunar wave is supplemented by some smaller waves with shorter periods but not by a lunar wave. This semilunar variation agrees surprisingly well with the same variation found in the sudden cardiovascular mortality data in Brno (400,000 inhabitants), Czech republic,within 1975–1983. This data set includes all cases of sudden death due to cardiovascular defeat at home, etc., not in hospital (i.e., earlier than medical assistance arrived). The maxima of the semilunar wave lay two days before the first and two days before the last quarters and their position depends on the solar cycle. Moreover, waves with periods between 3 and 4 days appear to be significant as well. All these periodicities in both data sets (from Romania and from Brno) are only connected with the lunar month and are not pronounced if these data are arranged with respect to some other effects (e.g., solar rotation).
