Cardiac arrest & resuscitation
Prolonged follow-up after apparently unexplained sudden cardiac arrest: A retrospective study
Authors' conclusion
Our findings emphasized that approximately a quarter of patients who had been initially considered as having apparently USCA after index hospital stay actually reveal heart conditions, especially electrical heart disorders.
Study context
- Population
- Out-of-hospital cardiac arrest (OHCA) patients admitted alive to a cardiac arrest centre, 2002–2022
- Participants
- 2,482 OHCA patients
- Exposure
- Unexplained sudden cardiac arrest (USCA) vs electrical heart disorders vs other cardiac etiologies of OHCA
- USCAn = 68
- Electrical heart disordersn = 30
- Outcome
- New diagnoses established during follow-up of USCA survivors
- Follow-up
- Mean 8.1 ± 6.3 years
