AB Cardiogenic  shock  is  an  acute  state  of  decreased  cardiac  output  resulting  in  inadequate  tissue  perfusion  despite  adequate  circulating  volume.  Cardiogenic  shock  is  the  leading  cause  of  in-hospital  death  in  patients  with  acute  myocardial  infarction  (AMI).1  The  true  incidence  of  cardiogenic  shock  is  unknown  because  many  patients  die  before  arrival  and  escape  estimates.  Cardiogenic  shock  is  seen  in  4%  to  8%  of  patients  with  ST-segment  elevation  myocardial  infarction  (STEMI).2,3  The  incidence  is  declining  in  part  as  a  result  of  the  increased  use  of  percutaneous  intervention  for  AMI.3,4,5,6  Cardiogenic  shock  occurs  less  frequently  (2.5%)  in  those  with  non–ST-segment  elevation  myocardial  infarction  (NSTEMI)  compared  with  those  with  STEMI.7,8  Only  ~10%  of  AMI  patients  who  will  develop  cardiogenic  shock  have  it  at  ED  presentation,  with  the  median  time  of  onset  after  arrival  being  approximately  6  hours.2,9  This  underscores  the  therapeutic  opportunity  that  exists  by  thwarting  ongoing  myocardial  ischemia.
