Usefulness of cooling and coronary catheterization to improve survival in out-of-hospital cardiac arrest.

Abstract

Survival rates after out-of-hospital cardiac arrest (OHCA) continue to be poor. Recent evidence suggests that a more aggressive approach to postresuscitation care, in particular combining therapeutic hypothermia with early coronary intervention, can improve prognosis. We performed a single-center review of 125 patients who were resuscitated from OHCA in 2 distinct treatment periods, from 2002 to 2003 (control group) and from 2007 to 2009 (contemporary group). Patients in the contemporary group had a higher prevalence of cardiovascular risk factors but similar cardiac arrest duration and prehospital treatment (adrenaline administration and direct cardioversion). Rates of cardiogenic shock (48..
