A retrospective patient record analysis of the Emergency Medial Service’s Rîga City Regional Centre was provided from January 2012 through December 2013. 1359 adult patients were CPR treated for out-of-hospital cardiac arrest according to ERC Guidelines 2010. A total of 490 patients were excluded from the study. The main outcome measure was survival to hospital admission. Of 869 CPR-treated patients, 60% (n = 521) were men. The mean age of patients was 66.68 ± 15.28 years. The survival rate to hospital admission was 12.9% (n = 112). 54 of survived patients were women. Mean patient age of successful CPR was 63.22 ± 16.21 and unsuccessful CPR 67.20 ± 15.09. At least one related illness was recorded with 63.4% (n = 551) patients. There were 61 survivors in bystander witnessed OHCA and nine survivors in unwitnessed OHCA. The rate of bystander CPR when CA (cardiac arrest) was witnessed was 24.8%. Ventricular fibrillation (VF) as initial heart rhythm was significantly associated with survival to hospital admission in 54 cases (p < 0.0001). Age and gender affected return of spontaneous circulation. Survival to hospital admission had rhythm-specific outcome. Presence of OHCA witnesses improved outcome compared to bystander CPR. The objective of this study was to report patient characteristics, the role of witnesses in out-of-hospital cardiac arrest (OHCA) and outcome of adult cardiopulmonary resuscitation
