AimTo describe the 3-year survival of patients after out-of-hospital cardiac arrest (OHCA) taking into account the presence of ST-segment elevation myocardial infarction (STEMI) and evaluating prognostic factors associated with pre-hospital and hospital care.Patient GroupOver a period of 29 months and with the aid of a questionnaire supplied to 24 rescue stations, we prospectively included 560 individuals (415 men; aged 16-97 years, median 68) for whom cardio-pulmonary resuscitation (CPR) for OHCA of confirmed cardiac etiology was attempted.ResultsOf 149 hospitalized individuals, 28.2% survived 1 year and 25.5% survived 3 years after OHCA. In the subgroup of patients with STEMI (26 individuals; 17.5%), 57.7% survived 1 year and 53.9% survived 3 years. In the subgroup of patients without STEMI (n=123), 22% survived 1 year and 19.5% survived 3 years. The strongest predictors for long-term survival by logistic regression analysis were: age under 70 years, ventricular fibrillation as initial rhythm, CPR without atropine, and STEMI. OHCA occurrence at a public place was an indicator of better survival in the subgroup with STEMI. In the subgroup of patients without STEMI, long-term angiotensin-converting enzyme inhibitor treatment, CPR without atropine, a Glasgow Coma Scale upon hospital admission over 3, no presence of cardiogenic shock, and no manifestations of postanoxic encephalopathy (Fisher's exact test, chi(2) test) were indicators of better survival.ConclusionAmong 560 individuals with "primary cardiac" etiology OHCA and initiation of professional CPR, 8% survived 1 year and 7% survived 3 years. A higher survival rate among patients with STEMI was documented.
