[The epidemiology of out-of-hospital deaths due to acute coronary events in young Beijing adults].
OBJECTIVE
To explore the characteristics of status and different populations of prehospital death associated with acute coronary events among young adults in Beijing.


METHODS
Data of acute coronary events of hospitalization or death were obtained from the Hospital Discharge Information System from Beijing Public Health Information Center and Death Register System from Beijing Center for Disease Control in Beijing. The total case fatality rate of acute coronary events and proportion of prehospital coronary heart disease (CHD) death were compared upon gender, area, occupation and marital status among people aged between 25 - 45 years old.


RESULTS
A total of 3489 cases were identified during 2007 to 2009 with acute coronary events (male: 3183, female: 306), with a mean age of (40.5 ± 4.3) years old. The 3-years' overall mortality was 26.0%, with female's higher than male's (51.0% vs 23.6%, P < 0.05); and it was higher in rural area than in urban areas (28.9% vs 22.9%, P < 0.05). Ninety-five percent of death due to acute coronary events occurred prehospital, with the proportion of 95.2% in male and 94.2% in female. Among the people with different occupations, self-employed people had the highest rate of prehospital death. Majority of prehospital deaths (64.8%) occurred at home.


CONCLUSIONS
More than 90% of deaths caused by acute coronary events among young adults aged between 25-45 years old occurred before been admitted into hospital, and the site of prehospital deaths was mainly at home.
