title: [Primary risk factors in Chinese patients with first acute myocardial infarction].
abstract: OBJECTIVE
  To analyze the primary risk factors of patients with first ST elevation acute myocardial infarction (FSTEMI) in Beijing and Shenyang area between 2004--2005. The Attributable risk percentage (ARP) and population attributable risk percentage (PARP) of every risk factor were determined.
  
  
  METHODS
  A total of 426 consecutive FSTEMI patients and 426 gender and age matched healthy controls were included in this 1:1 matched case-control study.
  
  
  RESULTS
  Multivariate logistic regression analysis showed that following 8 primary risk factors were associated with FSTEMI: heavy smoking (OR = 3.170), diabetes (OR = 2.835), positive family history (OR = 2.243), lack of soybeans intake (OR = 2.243), higher psychological stress (OR = 2.138), lack of fish intake (OR = 1.740), lower education level (OR = 1.572) and recent adverse life events (< 6 months before FSTEMI, OR = 1.515). The ARP are 71.53%, 58.33%, 54.05%, 40.81%, 56.85%, 41.53%, 48.62%, 54.00%; the PARP are 38.79%, 10.40%, 4.69%, 33.72%, 36.03%, 24.96%, 29.56%, 14.83%, respectively.
  
  
  CONCLUSIONS
  In this patient cohort, the harmful risk factors responsible for the development of FSTEMI in Beijing and Shenyang areas during 2004--2005 are heavy smoking, higher psychological stress, lack of soybeans intake, lower education level, lack of fish intake, recent adverse life events, diabetes and positive family history.
