Although acute myocardial infarction is a common cause of out-of-hospital cardiac arrest (OHCA), the role of early coronary angiography in OHCA remains uncertain. We conducted a meta-analysis of observational studies to determine the association of early coronary angiography with survival in OHCA. ⋯ Among patients resuscitated from OHCA, early coronary angiography is associated with increased survival to discharge and favourable neurological outcome.
