title: [Study on the association of -689C/T polymorphism in the PPARgamma2 promoter with myocardial infarction].
abstract: OBJECTIVE
  To investigate the association of -689C/T polymorphism in the peroxisome proliferator-activated receptor-gamma2 (PPARgamma2) promoter with myocardial infarction (MI).
  
  
  METHODS
  This is a case-control study, which included 194 subjects with MI and 693 subjects without MI in nondiabetic Han population in Wuhan. Polymerase chain reaction-restriction fragment length polymorphism was used to determine the -689C-->T substitution.
  
  
  RESULTS
  The CC,CT, and TT genotype frequencies of -689C/T polymorphism were 88.1%,11.9%,and 0.0 in MI patients and 93.1%,6.6%,and 0.3% in controls, respectively (CC vs. CT+TT, P=0.025). The -689T allele was an independent risk factor for MI (OR=2.125, 95%CI: 1.206-3.744, P=0.009) after adjusting for age,sex,waist circumference,body mass index, smoking, alcohol drinking, physical activities, systolic blood pressure, diastolic blood pressure, fasting blood glucose, total cholesterol, triglyceride, level. The -689T allele carriers had significantly higher TC levels than noncarriers [(5.05+/-1.16) mmol/L vs. (4.78+/-1.05) mmol/L, P=0.004] in the total population.
  
  
  CONCLUSIONS
  The PPARgamma2 promoter -689C/T polymorphism is associated with an increased risk of MI.
