In the present study we evaluated whether two polymorphisms of β2-adrenergic receptors (β2-AR) gene (R16G and Q27E) could modify the risk of myocardial infarction (MI). Using a case-control design, we analyzed the data from 125 male patients who had experienced a first episode of MI before the age of 45 years and 108 male controls matched for age. The allele frequencies for R16G and Q27E were: G16=0.56 and E27=0.36 in patients with MI and G16=0.61 and E27=0.42 in the control group. There was a trend (not statistically significant) of decreasing MI risk according to E27 or G16 alleles. Combined effect between E27 allele and history of dyslipidemia has been observed. Whereas dyslipidemia conferred a relative risk of MI of 4.8 (P2-adrenergic receptor has a significant protective effect on MI in dyslipidemic young male.
