Purpose: The purpose of this study was to describe and compare the return of spontaneous circulation (ROSC) cases of out-of-hospital cardiac arrest on the basis of Heart Saver laureate. Methods: This study aimed to investigate the cardiopulmonary resuscitation (CPR) outcomes and the clinical characteristics of patients with out-of-hospital cardiac arrest by analyzing the data of two regions. The data were prehospital emergency reports of 473 patients who survived for ＞ 72 hours after ROSC in two region from January 2012 to December 2013. Results: Among the ROSC patients, 86.8% (G), 77.9% (S) were men and 72.9% (G), 67.9% (S) were of age 41~70 years, 87.6% (G), 82.9% (S) had a witnessed cardiac arrest; and 66.7% (G), 70.6% (S) received cardiopulmonary resuscitation from bystander. Of those who performed the resuscitation, paramedics in 89.1% (G), 89.8% (S). Furthermore, 119 emergency medical technicians were involved in 69.0% of two-rescue teams in G and in 90.4% of three-rescue team in S. Conclusion: Most heart savers were qualified paramedics, and three-rescuer-teams resulted in better survival rate than two-rescuer-teams.
