Day-of-the-week variation of sudden unexpected cardiac death
Background: There has been some controversy about the day-of-the-week (septadian) variation of unexpected sudden cardiac death (SCD). Methods: We evaluated the incidence of unexpected SCD on different days of the week in a consecutive series of 5869 SCD victims from Northern Finland [the FINGESTURE...

| Summary: | Background: There has been some controversy about the day-of-the-week (septadian) variation of unexpected sudden cardiac death (SCD). Methods: We evaluated the incidence of unexpected SCD on different days of the week in a consecutive series of 5869 SCD victims from Northern Finland [the FINGESTURE study (Finnish Genetic Study of Arrhythmic Events)]. As it is mandatory in Finland, a medico-legal autopsy was performed on all unexpected sudden death victims. The autopsies were performed between the years 1998–2017. Results: The mean incidence of unexpected SCD was higher at weekends (during the days from Friday to Sunday, peaking on Saturday) than during the days from Monday to Thursday (8.54 ± 0.72 vs. 7.22 ± 0.19 SCDs per day of the week per 100,000 inhabitants per year, p < 0.001). Regardless of sex or ischemic versus non-ischemic etiology of SCD, the distribution of the occurrence of SCD among the days of the week was similar compared with the whole SCD cohort. Conclusion: The incidence of unexpected SCD was highest at weekends (during the days from Friday to Sunday, peaking on Saturday). |
