Abstract 131: Cardiac Arrest Due to Cardiac Etiology: A Progress Report on the Past 20 Years in an Emergency Department in Vienna
Background: Based on demographic changes in the western world, the number of patients with cardiac arrest due to a cardiovascular event is continuously rising. A large variety of factors impacting on favorable neurological outcome (CPC 1-2) and the 6-month survival, are well established. The question whether the knowledge about these predictive factors result in improved outcome over the last 20 years, has not been proven within a long-term study so far.
Methods: We prospectively identified 2670 patients (out-of hospital [OOH], n = 1822; in-hospital [IH], n = 848) with cardiac arrest of cardiac etiology and ventricular fibrillation as a first rhythm treated at our emergency department between January 1992 and December 2012. Chi-square test and Cochran-Mantel-Haenszel test have been used to assess differences in CPC and 6-month survival within the observation-period.
Results: Within our total cohort, 2189 patients (82.0%) survived the initial event. After a follow-up period of 6 months, 1007 patients (46%) with ROSC deceased. A favorable CPC (1-2) after 6 months has been detected in 1197 patients (54.7%). Within the last 20 years there was an improvement of favorable neurological outcome (CPC 1-2) (p<0.001) and as well a reduction of 6-month mortality rates (p=0.004).
Independently in patients with IH cardiac arrest, 78.5% (n=666) survived the initial event, but the 6-month survival rate (n=381, 57.2%) and the favorable CPC outcome (n=443, 66.5%) were approximately higher. Independently within IH cardiac arrest patients a reduction of 6-month mortality rates (p=0.048) was found. Still there were constantly high rates of favorable neurological outcome (CPC 1-2) after 6 months, but there was no improvement within the past 20 years (p=0.665).
Conclusion: We were able to demonstrate, that outcome of patients with cardiac arrest of a cardiac etiology has improved significantly within the last 20 years. This gives the impression, that critical care medicine on a high level for patients with cardiac arrest even in the emergency department could be important for outcome. If such specific cardiac arrest centers merged with emergency departments prove to be valuable for ideal patient care has to be further evaluated in detail.
