Which patients post cardiac arrest should go to the cath lab?

This topic remains a little controversial, but according to a recent review:

The high rate of acute coronary occlusion, the lack of clear means to select ideal candidates, and the benefit associated with early PCI strongly encourage performing a systematic coronary angiography in all OHCA patients, providing that there is no obvious noncardiac cause of arrest. Several questions remain unsolved but at this time, this strategy appears to be the most secure and the best adapted in these patients.
