Does immediate percutaneous coronary intervention improve hospital survival in patients with out-of-hospital cardiac arrest?
Immediate percutaneous coronary intervention is associated with better hospital survival in out-of-hospital cardiac arrest patients regardless of the presence of ST-segment elevation.
Successful immediate coronary angioplasty is associated with improved hospital survival in patients with or without ST-segment elevation. Therefore, our findings support the use of immediate coronary angiography in patients with out-of-hospital cardiac arrest with no obvious noncardiac cause of arrest regardless of the ECG pattern.
Dumas et al. (2010) studied this question.
