Cardiac arrest & resuscitation
Scoping review of echocardiographic parameters associated with diagnosis and prognosis after resuscitated sudden cardiac arrest
Authors' conclusion
This scoping review highlights the limited data on early echocardiography in providing etiology of arrest and prognostic information after resuscitated sudden death.
Study context
- Population
- Adults with early (<48 h) echocardiography after resuscitation from non-traumatic sudden death
- Participants
- 2,035 adults · 16 studies
- Outcome
- Diagnostic: associations of RWMA, ventricular function and structural abnormalities with cardiac etiologies of arrest; prognostic: associations of echocardiographic findings with survival to hospital discharge and favorable neurological outcome
Main finding
As reported in the abstract
- Studies formally reporting diagnostic accuracy for cardiac etiology
- 2 of 6
- Regional wall motion abnormalities (RWMA) associated with presumed cardiac ischemia (5 of 6 studies)
- 17-89%
- No association of reduced LVEF with favorable neurologic status
- n = 5
- High mitral E/e' ratio associated with poor survival
- n = 1
- RV systolic dysfunction associated with poor survival
- n = 2
