gene -572 G > C polymorphism and myocardial infarction risk.

INTRODUCTION

The association between () gene -572 G^C polymorphism and myocardial infarction (MI) risk has not been established. We adopted this meta-analysis for further insight into the case-control studies.

MATERIALS AND METHODS

To investigate the genetic association, we searched multiple databases, including Web of Science, EMbase, CBM disc, PubMed and CNKI. Also, we manually identified the searched references. All the statistical analyses were conducted using Stata 11.0.

RESULTS

A total of five studies were identified, involving 2,526 MI cases and 3,027 controls. The results revealed a significant association between gene -572 G^C polymorphism and MI, implying that the gene -572 C allele may be a protective factor for MI (for C allele vs K allele: OR = 0.85, 95% CI = 0.73-0.99, = 0.041; for C/C vs G/G: OR = 0.55, 95% CI = 0.31-0.98, = 0.044; for C/C vs G/C + G/G: OR = 0.60, 95% CI = 0.41-0.89, = 0.011). However, in the subgroup analysis with regard to ethnicity, no significant correlation was identified between gene -572 G^C polymorphism and MI among Europeans.

CONCLUSION

The gene -572 C allele may be a protective factor for MI. Future studies involving larger sample bases are still recommended.
