Background It has been suggested that the a ngiotensinogen ( AGT ) gene rs4762 (p.Thr174Met) polymorphism might be associated with myocardial infarction (MI) risk, but the study results are still debatable. Objective and Methods . In order to explore the relationship between AGT p.Thr174Met polymorphism and MI risk, the current meta-analysis involving 7657 subjects from 11 individual studies was conducted.Results A significant association between AGT p.Thr174Met polymorphism and MI was found under recessive (OR: 2.26, 95% CI: 1.35-3.77, P = 0.002), dominant (OR: 1.131, 95% CI: 1.016-1.260, P = 0.024), codominant (OR: 2.198, 95% CI: 1.334-3.621, P = 0.002), and additive (OR: 1.363, 95% CI: 1.132-1.641, P = 0.001) genetic models. In the Asian subgroup, significantly increased MI risk was found under all genetic models ( P < 0.05). No significant association between AGT p.Thr174Met polymorphism and MI was found under all genetic models in the Caucasian subgroup ( P > 0.05).Conclusions AGT p.Thr174Met variant might increase MI risk, especially within the Asian population. The Met174 allele of AGT p.Thr174Met might confer the risk for MI.
