Acute cardiac care & resuscitation
DanGer shock criteria and outcomes in acute myocardial infarction-related cardiogenic shock treated with Impella: the J-PVAD registry
Authors' conclusion
In this nationwide registry, one-third of AMI-CS patients treated with Impella met DanGer shock criteria. Outcomes in non-eligible subgroups were heterogeneous

Risk factors for mortality in non-eligible STEMI-CS
- Mortality increased significantly with advanced age, renal dysfunction, VA-ECMO use, ventricular arrhythmia or sepsis
