Diurnal, weekly and seasonal variation of sudden death. Population-based analysis of 24061 consecutive cases
Abstract
AIMS: Several studies have reported circadian and seasonal variations in acute cardiovascular disease. In addition, a weekly variation has been observed in acute myocardial infarction. The aim of our study was to determine the circadian weekly, and seasonal variations of sudden death utilizing population-based data. METHODS AND RESULTS: We analysed the emergency medical system data of Berlin (West) from 1987-1991 with respect to all consecutive sudden deaths in subjects >18 years (n=24 061). There was a marked circadian variation of sudden death, with a minimum between 0 and 6 h and a maximum between 6 and 12 h (P<0.0001) for every day of the week. A minimum of events occurred on Sundays (n=3143), and a maximum on Mondays (n=3721), corresponding to a relative increase of 18.3% (P<0.0001). The increase was more pronounced (23.6%) in patients < or =65 than in patients >65 (15.7%). In addition, we found a significant seasonal variation (P<0.0001) in events, with a maximum during winter (December to February, n=6493), and a minimum during summer (June to August, n=5472), corresponding to a relative difference of 18.7%. The seasonal variation was more pronounced in patients >65 years. CONCLUSION: The present analyses demonstrate marked variations in the occurrence of sudden death with peaks during morning hours, on Mondays, and during winter months. The findings suggest that the onset of sudden death may be associated with endogenous rhythms and external factors including climatic conditions.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
