Acute cardiac care & resuscitation
Incidence, analysis and risk of out-of-hospital cardiac arrest in individuals with non-ischaemic dilated cardiomyopathy
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.
