In this multicenter, national analysis of ICU admission for critically ill patients with AMI, we found that admission to the Cardiac Intensive Care Unit (CICU) was associated with lower in-hospital mortality than patients admitted to the medical ICU (MICU).

These findings persisted when analyzed by hospital type and critical diagnoses (eg, cardiogenic shock and cardiac arrest).

Finally, patients admitted to the CICU more commonly underwent cardiac critical care therapies and a similar proportion of historically described noncardiac critical care therapies.

Future research is needed to explore other specific disease states that may benefit from CICU triage as well as to identify patient-specific factors driving these findings.
