Cardiac arrest & resuscitation
Prodromal complaints and 30-day survival after emergency medical services-witnessed out-of-hospital cardiac arrest
Authors' conclusion
Experiencing chest pain or heart palpitations prior to EMS-witnessed OHCA was associated with higher 30-day survival. Conversely, complaints of unresponsiveness or having blue skin or lips implied reduced odds of 30-day survival.
