Acute cardiac care & resuscitationCase-control study
Incidence, analysis and risk of out-of-hospital cardiac arrest in individuals with non-ischaemic dilated cardiomyopathy
- observational, register-based study with cohort and nested case-control analyses
- nationwide
- exposure-matched cohort
Authors' conclusion
The Danish NIDCM population has a significantly increased incidence of OHCA compared to the general population but a comparable mortality despite multiple positive resuscitation characteristics.
