Incidence, Mortality, and Outcome-Predictors of Sudden Cardiac Arrest Complicating Myocardial Infarction Prior to Hospital Admission

More than 1 of 20 STEMI presents prehospital SCA after EMS arrival. SCA occurrence is associated with a 10-fold higher mortality at hospital discharge compared with STEMI without SCA. PCI is the strongest survival predictor, leading to a twice-lower mortality. This highlights the persistently dramatic impact of SCA on STEMI and the major importance of PCI in this setting.
