Early Impella support in post-cardiac arrest cardiogenic shock complicating acute myocardial infarction improves short and long term survival


 
 
 Early mechanical circulatory support with Impella may improve survival outcomes in the setting of post-cardiac arrest cardiogenic shock (CS) after out of hospital cardiac arrest (OHCA) complicating acute myocardial infarction (AMI). However, the optimal timing to initiate mechanical circulatory support (MCS) in this particular setting remains unclear.
 
 
 
 We aimed to compare survival outcomes of patients supported with Impella 2.5 before percutaneous coronary intervention (PCI) (pre-PCI) to those supported after PCI (post-PCI).
 
 
 
 Single center study of patients resuscitated from OHCA due to AMI with post-cardiac arrest CS between September 2014 and June 2018. Survival outcomes were compared between those with Impella support before and after PCI.
 
 
 
 A total of 65 consecutive patients with infarct-related post-cardiac arrest shock supported with Impella 2.5 during admission coronary angiogram were included. All patients were in profound CS requiring catecholamines on admission. Overall survival to discharge and at 12-months was 44.6% and 41.5%, respectively. Patients in the pre-PCI group had a higher survival to discharge and at 12-months as compared to patients of the post-PCI group (60.7% versus 32.4%, p=0.03 and 57.1% versus 29.7%, p=0.04, respectively). Moreover, the patients in the early support group demonstrated a greater functional recovery of the left ventricle when Impella support was initiated prior to PCI.
 
 
 
 Our results suggest that the early initiation of MCS with Impella 2.5 prior to PCI is associated with improved hospital and 12-month survival in patients with post-cardiac arrest CS complicating AMI.
