Sports-related sudden cardiac deaths (SrSCDs) occur most frequently
in highly dynamic and/or static sports. We aimed to assess the incidence and
characteristics of SrSCDs in Switzerland and to compare SrSCD occurrence
according to sports categories with the sports participation behaviour in the
general population. METHODS: Between 1999 and 2010, forensic reports of SrSCDs in
young individuals (10-39 years of age) were retrospectively reviewed and
categorised based on peak static (increasing from I to III) and dynamic sports
components (increasing from A to C). Data were compared to the sports
participation behaviour of the Swiss population. RESULTS: Sixty-nine SrSCDs were
identified. Forty-eight (69.6%) occurred during recreational sports (REC) and 21
(30.4%) during competitive sports (COMP). Incidences
(per 100,000 athlete
person-years) for COMP and REC were 0.90 and 0.52, respectively (p = 0.001). Most
SrSCDs occurred in IC (23 cases, 33.3%), followed by IIC (13, 18.9%), IIIA and
IIIC (11 each, 15.9%), IIIB (6, 8.7%), IIA (4, 5.8%) and IB sports categories (1,
1.5%). No SrSCDs were found in IA and IIB sports categories. Incidences between
sports categories (IIIA 0.25, IB 0.25, IC 0.18, IIC 0.33 and IIIC 0.25) were not
significantly different except to IIA (0.94, p < 0.001), due to the fact that few
people were involved in this sports category. Coronary artery disease (CAD) was
the most common underlying pathology of SrSCD. CONCLUSIONS: In this Swiss cohort,
incidence of SrSCD was very low and similar in all sports categories classified
by their static and dynamic components. However, the incidence was higher in COMP
compared to REC, and CAD proved to be the most common underlying cause of SrSCD.
