AbstractWe analyzed long-term follow-up data accumulated during an 8 year study of survivors of prehospital cardiac arrest. All patients included in this study were primary entrants via community-based rescue systems; patients who were tertiary referrals (survivors of cardiac arrest from other hospitals) were not included in this analysis. In the group of 61 patients entering our study between 1975 and 1980, with a follow-up to 1983, there have been a total of 24 deaths (39%). Sixteen of the 24 deaths were the result of recurrent cardiac arrest; eight were nonsudden cardiac deaths or noncardiac deaths. The mean duration from entry to death in the nonsurvivors was 27.5 +/- 19.7 months, and the time from the index event to last follow-up in the long-term survivors was 59.9 +/- 19.4 months. Life table analysis demonstrated a 10% rate of recurrence of cardiac arrest in the first year, with a 5% per year rate in each of the subsequent 3 years. Left ventricular ejection fractions at entry were not significantly different between survivors (mean = 45.3 +/- 13.6%) and nonsurvivors (mean = 37.6 +/- 12.6%), and the severity of ejection fraction abnormality at entry did not correlate with time to death in the nonsurvivors. However, ejection fraction was significantly lower in patients who died from causes other than recurrent cardiac arrest than in those who died of cardiac arrest (24.5 +/- 9.1% vs 42.7 +/- 9.2%; p less than .002).(ABSTRACT TRUNCATED AT 250 WORDS)
