Abstract

Introduction. The aim of this multicentre prospective study was to describe the seven-year survival of patients, from the region of East Bohemia, after out-of-hospital cardiac arrest (OHCA), occurring between  2002 and  2004. The main focus of this study was on the survival of patients with ST-segment elevated myocardial infarction (STEMI).
Patients and Methods. A total 718 patients  with OHCA were included in the study. Of these patients, 149 were admitted to hospital. The main cohort of our study consisted of 53 patients (41 men; median 59; average 58±13), who survived acute hospitalization. In these patients, STEMI was the main cause of OHCA in 15 cases (28%), whereas without STEMI was found in 38 cases (72%). Patients who survived hospitalization were periodically followed-up at six-monthly intervals.
Results. In the first follow-up year, 42 patients survived (79% of 53 patients), in the third year 38 patients (72%), in the fifth year 33 patients (62%) and in the seventh year 31 patients (59%). Ninety-four percent of patients were in good neurological condition after the seventh follow-up year. The whole period of seven years was survived by 12 (80%) out of 15 patients with STEMI, and by 19 (50%) out of 38 patients without STEMI. In patients who survived the seventh year after STEMI, direct percutaneous coronary intervention was performed in 11 cases.
Conclusions. Fifty-nine percent of patients discharged from hospital after OHCA   survived until the seventh year. The highest rate of survival during this period was seen in patients with STEMI, i.e. in 80%.
