Characteristics and short-term survival of individuals with out-of-hospital cardiac arrests in the East Bohemian region

SUMMARYHealth care associated with cardiac arrest exhibits a significant economic burden, rather than effectiveness.Hypothesis: The time of the out-of-hospital cardiac arrest (OHCA) onset during a diurnal period alters the survival chance.Professionally resuscitated patients for witnessed OHCA (n = 495) from the study were prospectively followed for 12 months. The distribution of the onset of cardiac arrest during the 24-hour period was tested in the survivors (the total group, the other groups).In the ultrashort-term survivors (n = 136, follow-up = admission to hospital) the highest incidence was seen between 18:01-22:00 h. The same trend was seen in both the shortterm (n = 48, follow-up = discharge from hospital) and the long-term survivors (n = 39, follow-up = 1 year). Furthermore, when the ultrashort-, short-, and long-term survivors were analysed according to indicators of prehospital care (early electrical defibrillation ≤5 min, bystander cardiopulmonary resuscitation, ambulance response time ≤10 min; locations of arrest; initial cardiac rhythms) an OHCA peak was observed for early defibrillation and ambulance response time (ultrashort-term survivors, 18:01-22:00 h) and/or in the case of OHCA that occurred in a public place (short-term survivors, 18:01-22:00 h). The lowest incidence of cardiac arrest was between 22:01-06:00 h in all groups.The evening incidence of OHCA reflects a higher chance of survival in our study area (East Bohemian region).

aOut-of-hospital cardiac arrest (OHCA) is a leading cause of death in developed industrial countries. The global worldwide average of OHCA incidence in adults is 95.9/100,000/year. European incidences vary according to source from 16 to 119/100,000/year. The aim of this study was to provide an overview of current information on OHCA. The incidences in various populations are discussed, along with the factors affecting the prognosis and outcome of these patients. The etiology and pathophysiological mechanisms are also described, especially in relation to the most common causes -acute and chronic forms of coronary artery disease and cardiomyopathies. Measures that could improve survival rates are discussed, with emphasis on the role of the general public and deployment of automatic external defibrillators.

Background: Early reperfusion by direct percutaneous coronary intervention (PCI) in patients with ST segment elevation acute myocardial infarctions (STEMI) with an out-of-hospital cardiac arrest (OHCA) reduces hospital and longterm mortality. Aims: Evaluating the significance of direct PCI for the short-term (discharge from acute hospitalization) and 1-year survival in patients with acute STEMI after OHCA. Methods: In this prospective study, from April 1, 2002 up to August 31, 2004, a total of 26 hospitalized individuals (22 men, 4 women, aged 35–79 years, median 58.5) from the East Bohemian region with OHCA (primary group of 718 individuals) with acute STEMI were included. Urgent coronary angiography was performed in 20 individuals, and direct PCI was done in 19 of them. The remaining 6 patients did not undergo angiography. Results: Fifteen patients (57.7%) survived acute hospitalization, of whom 11 were without neurological deficits. In the subgroup with urgent coronary angiography 14 patients (70%) survived hospitalization, and in the subgroup without coronarography only 1 patient survived hospitalization (16.7%). In the subgroup with PCIs, 13 out of the 19 patients survived (68.4%). None of the patients died during the 1-year follow-up after being discharged from acute hospitalization. According to the urgent coronarography the artery most commonly responsible for the infarction was the left anterior descending artery (50%). Initial TIMI flow grade 0–I was found in 17 patients and grade II–III in 3 individuals. After PCI, irrespective of stent implantation, an optimal angiographic success (TIMI flow grade II–III) was obtained in 17 cases. Conclusion: Short-term survival of patients after OHCA with STEMI treated with direct PCI was found to be 68.4%. Out of 6 patients not receiving reperfusion therapy 1 survived (16.7%). Over the course of the 1-year follow-up none of the patients died.
