Long-term performance of subcutaneous implantable defibrillators in athletes: A multicenter, real-world analysis of sport activities from the iSUSI registry
Authors' conclusion
Sports practice was not associated with an increased risk of complications or inappropriate shocks, although athletes are exposed to a higher risk of S-ICD infections in the early postoperative period.

Main finding
As reported in the abstract
Overall device-related complications (yearly rate)
- No differences in overall device-related complications
- Athletes vs Nonathletes: P = 0.448
Observational data: associations, not effects.
