Authors' conclusion

This study found that a strategy of immediate coronary angiography does not provide clinical benefit compared with a delayed or selective invasive approach for patients 1 year after resuscitated OHCA of presumed coronary cause and without ST-segment elevation.

Study context

Population
Resuscitated OHCA of presumed cardiac origin with stable return of spontaneous circulation, without ST-segment elevation on postresuscitation ECG

Comparison
Immediate vs delayed or selective coronary angiography
  • Immediate angiographyn = 281
  • Delayed or selectiven = 273reference
